This resource is using open-source code maintained in github (see the quick-start-guide section) and available for download from NGC

Bidirectional Encoder Representations from Transformers (BERT) is a new method of pre-training language representations that obtains state-of-the-art results on a wide array of Natural Language Processing (NLP) tasks. This model is based on the BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding paper.

This repository contains scripts to interactively launch data download, training, benchmarking, and inference routines in a Docker container for pre-training and fine-tuning tasks such as question answering. The major differences between the original implementation of the paper and this version of BERT are as follows:

Scripts to download the Wikipedia dataset
Scripts to preprocess downloaded data into inputs and targets for pre-training in a modular fashion
LAMB optimizer to support training with larger batches
Adam optimizer for fine-tuning tasks
Automatic mixed precision (AMP) training support

Other publicly available implementations of BERT include:

This model trains with mixed precision Tensor Cores on NVIDIA Ampere and provides a push-button solution to pre-training on a corpus of choice. As a result, researchers can get results 4x faster than training without Tensor Cores. This model is tested against each NGC monthly container release to ensure consistent accuracy and performance over time.

Model architecture

The BERT model uses the same architecture as the encoder of the Transformer. Input sequences are projected into an embedding space before being fed into the encoder structure. Additionally, positional and segment encodings are added to the embeddings to preserve positional information. The encoder structure is simply a stack of Transformer blocks, which consist of a multi-head attention layer followed by successive stages of feed-forward networks and layer normalization. The multi-head attention layer accomplishes self-attention on multiple input representations.

An illustration of the architecture taken from the Transformer paper is shown below.

$\"BERT\"$

Default configuration

The architecture of the BERT model is almost identical to the Transformer model that was first introduced in the Attention Is All You Need paper. The main innovation of BERT lies in the pre-training step, where the model is trained on two unsupervised prediction tasks using a large text corpus. Training on these unsupervised tasks produces a generic language model, which can then be quickly fine-tuned to achieve state-of-the-art performance on language processing tasks such as question answering.

The BERT paper reports the results for two configurations of BERT, each corresponding to a unique model size. This implementation provides the same default configurations, which are described in the table below.

Features

Fleet is a unified API for distributed training of PaddlePaddle.

LAMB stands for Layerwise Adaptive Moments based optimizer, which is a large batch optimization technique that helps accelerate the training of deep neural networks using large minibatches. It allows using a global batch size of 65536 and 32768 on sequence lengths 128 and 512, respectively, compared to a batch size of 256 for Adam. The optimized implementation accumulates 1024 gradient batches in phase 1 and 4096 steps in phase 2 before updating weights once. This results in a 15% training speedup. On multi-node systems, LAMB allows scaling up to 1024 GPUs resulting in training speedups of up to 72x in comparison to Adam. Adam has limitations on the learning rate that can be used since it is applied globally on all parameters, whereas LAMB follows a layerwise learning rate strategy.

LDDL is a library that enables scalable data preprocessing and loading. LDDL is used by this PaddlePaddle BERT example.

Mixed precision training

Mixed precision is the combined use of different numerical precisions in a computational method. Mixed precision training offers significant computational speedup by performing operations in half-precision format while storing minimal information in single-precision to retain as much information as possible in critical parts of the network. Since the introduction of Tensor Cores in NVIDIA Volta, and following with both the NVIDIA Turing and NVIDIA Ampere architectures, significant training speedups are experienced by switching to mixed precision -- up to 3x overall speedup on the most arithmetically intense model architectures. Using mixed precision training requires two steps:

Porting the model to use the FP16 data type where appropriate.
Adding loss scaling to preserve small gradient values.

The ability to train deep learning networks with lower precision was introduced in the Pascal architecture and first supported in CUDA 8 in the NVIDIA Deep Learning SDK.

For information about:

How to train using mixed precision in PaddlePaddle, refer to the Mixed Precision Training paper and Automatic Mixed Precision Training documentation.
Techniques used for mixed precision training, refer to the Mixed-Precision Training of Deep Neural Networks blog.

Enabling mixed precision

Mixed precision is enabled in Paddle by using the Automatic Mixed Precision (AMP) while storing variables in single-precision format. Furthermore, to preserve small gradient magnitudes in backpropagation, a loss scaling step must be included when applying gradients.\nIn PaddlePaddle, loss scaling can be easily applied by passing in arguments to GradScaler(). The scaling value to be used can be dynamic or fixed.

For an in-depth walkthrough on AMP, check out sample usage here. Paddle AMP is a PaddlePaddle built-in module that provides functions to construct AMP workflow. The details can be found in Automatic Mixed Precision (AMP), which requires minimal network code changes to leverage Tensor Cores performance.

Code example to enable mixed precision for static graph:

Use paddle.static.amp.decorate to wrap optimizer

import paddle.static.amp as amp\nmp_optimizer = amp.decorate(optimizer=optimizer, init_loss_scaling=8.0)\n

Minimize loss , and get scaled_loss, which is useful when you need customized loss.

ops, param_grads = mp_optimizer.minimize(loss)\nscaled_loss = mp_optimizer.get_scaled_loss()\n

For distributed training, it is recommended to use Fleet to enable amp, which is a unified API for distributed training of PaddlePaddle. For more information, refer to Fleet

import paddle.distributed.fleet as fleet\nstrategy = fleet.DistributedStrategy()\nstrategy.amp = True # by default this is false\noptimizer = fleet.distributed_optimizer(optimizer, strategy=dist_strategy)\n

Enabling TF32

TensorFloat-32 (TF32) is the new math mode in NVIDIA A100 GPUs for handling the matrix math, also called tensor operations. TF32 running on Tensor Cores in A100 GPUs can provide up to 10x speedups compared to single-precision floating-point math (FP32) on NVIDIA Volta GPUs.

TF32 Tensor Cores can speed up networks using FP32, typically with no loss of accuracy. It is more robust than FP16 for models, which require a high dynamic range for weights or activations.

For more information, refer to the TensorFloat-32 in the A100 GPU Accelerates AI Training, HPC up to 20x blog post.

TF32 is supported in the NVIDIA Ampere GPU architecture and is enabled by default.

If `<--max-steps>` is not set or set to -1, it will be trained for `<--epochs>` epochs. If `<--max-steps>` is set to a positive number, the total training steps is calculated by: `total_steps = min(max_steps, epochs * steps_per_epoch)`.\n- For pre-training, `<--max-steps>` is required and `<--epochs>` is deprecated. Because We typically train for a specified number of steps rather than epochs.\n\n#### Multi-node\nMulti-node runs can be launched on a pyxis/enroot Slurm cluster (refer to [Requirements](#requirements)) with the `run.sub` script with the following command for a 4-node DGX-A100 example for both phase 1 and phase 2:\n \n```\nTRAIN_BATCH_SIZE=256 GRADIENT_ACCUMULATION_STEPS=8 PHASE=1 sbatch -N4 run.sub\nTRAIN_BATCH_SIZE=32 GRADIENT_ACCUMULATION_STEPS=32 PHASE=2 sbatch -N4 run.sub\n```\n \nCheckpoints after phase 1 will be saved in `checkpointdir` specified in `run.sub`. The checkpoint will be automatically picked up to resume training on phase 2. Note that phase 2 should be run after phase 1.\n \nThe batch variables `BATCHSIZE`, `GRADIENT_STEPS`,`PHASE` refer to the Python arguments `--batch-size`, `--gradient-merge-steps`, `--phase1/--phase2` respectively.\n \nNote that the `run.sub` script is a starting point that has to be adapted depending on the environment. In particular, variables such as `datadir` handle the location of the files for each phase. \n \nRefer to the file's contents to find the full list of variables to adjust for your system.\n\n### Command-line options\n \nTo view the full list of available options and their descriptions, use the `-h` or `--help` command-line option, for example:\n \n`python run_pretraining.py --help`\n \n`python run_squad.py --help`\n\nDetailed descriptions of command-line options can be found in the [Parameters](#parameters) section.\n \n### Getting the data\n\nFor pre-training BERT, we use the Wikipedia (2500M words) dataset. We extract \nonly the text passages and ignore headers, lists, and tables. BERT requires that\ndatasets are structured as a document level corpus rather than a shuffled \nsentence-level corpus because it is critical to extract long contiguous \nsentences. `data/create_datasets_from_start.sh` uses the LDDL downloader to \ndownload the Wikipedia dataset, and `scripts/run_pretraining.sh` uses the LDDL \npreprocessor and load balancer to preprocess the Wikipedia dataset into Parquet\nshards which are then streamed during the pre-training by the LDDL data loader.\nRefer to [LDDL's README](https://github.com/NVIDIA/LDDL/blob/main/README.md) for more \ninformation on how to use LDDL. Depending on the speed of your internet \nconnection, downloading and extracting the Wikipedia dataset takes a few hours,\nand running the LDDL preprocessor and load balancer takes half an hour on a \nsingle DGXA100 node.\n\nFor fine-tuning a pre-trained BERT model for specific tasks, by default, this repository prepares the following dataset:\n \n- [SQuAD](https://rajpurkar.github.io/SQuAD-explorer/): for question answering\n\n#### Dataset guidelines\n \nThe procedure to prepare a text corpus for pre-training is described in the above section. This section provides additional insight into how exactly raw text is processed so that it is ready for pre-training.\n \nFirst, raw text is tokenized using [WordPiece tokenization](https://arxiv.org/pdf/1609.08144.pdf). A [CLS] token is inserted at the start of every sequence, and the two sentences in the sequence are separated by a [SEP] token.\n \nNote: BERT pre-training looks at pairs of sentences at a time. A sentence embedding token [A] is added to the first sentence and token [B] to the next.\n \nBERT pre-training optimizes for two unsupervised classification tasks. The first is Masked Language Modeling (Masked LM). One training instance of Masked LM is a single modified sentence. Each token in the sentence has a 15% chance of being replaced by a [MASK] token. The chosen token is replaced with [MASK] 80% of the time, 10% with a random token and the remaining 10% the token is retained. The task is then to predict the original token.\n \nThe second task is next sentence prediction. One training instance of BERT pre-training is two sentences (a sentence pair). A sentence pair may be constructed by simply taking two adjacent sentences from a single document or by pairing up two random sentences with equal probability. The goal of this task is to predict whether or not the second sentence followed the first in the original document.\n\n### Training process\n \nThe training process consists of two steps: pre-training and fine-tuning.\n \n#### Pre-training\n\nPre-training is performed using the `run_pretraining.py` script along with parameters defined in the `scripts/run_pretraining.sh`.\n \nThe `run_pretraining.sh` script runs a job on a single node that trains the BERT-large model from scratch using Wikipedia datasets as training data using the LAMB optimizer. By default, the training script runs two phases of training with a hyperparameter recipe specific to 8x A100 80G cards:\n\nPhase 1: (Maximum sequence length of 128)\n- Runs on 8 GPUs with a training batch size of 256 per GPU.\n- Uses a learning rate of 6e-3.\n- Has AMP enabled.\n- Runs for 7038 steps, where the first 28.43% (2000) are warm-up steps\n- Saves a checkpoint every 200 iterations (keeps only the latest three checkpoints) and at the end of training. All checkpoints and training logs are saved to the `results/` directory (in the container, which can be mounted to a local directory).\n- Creates a log file containing all the output\n\nPhase 2: (Maximum sequence length of 512)\n- Runs on 8 GPUs with training batch size of 32 per GPU\n- Uses a learning rate of 4e-3\n- Has AMP enabled\n- Runs for 1563 steps, where the first 12.8% are warm-up steps\n- Saves a checkpoint every 200 iterations (keeps only the latest 3 checkpoints) and at the end of training. All checkpoints, and training logs are saved to the `results/` directory (in the container which can be mounted to a local directory).\n- Creates a log file containing all the output\n \nThe default hyperparameters in `run_pretraining.sh` will train BERT-large model using FP16 arithmetic on the Wikipedia dataset to state-of-the-art accuracy on a DGXA100 with 8x80GB A100 cards. 90% of the training steps are done with sequence length 128 (phase 1 of training) and 10% of the training steps are done with sequence length 512 (phase 2 of training).\n \n```shell\nbash run_pretraining.sh \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \n```\n\nWhere:\n- `` is the per-GPU batch size used for training.

Refer to [LDDL's README](https://github.com/NVIDIA/LDDL/blob/main/README.md) for more information.\n- `` is the path to the bert config file.\n- `` a flag to enable benchmark. The train process will warmup for `` and then measure the throughput of the following ``.\n\nNote that: \n- If users follow [Quick Start Guide](#quick-start-guide) to set up container and dataset, there is no need to set any parameters. For example:\n```shell\nbash scripts/run_pretraining.sh\n```\n- It's common for users to mount their own datasets or customize the hyperparameters. If so, it's better to specify all parameters in `scripts/run_pretraining.sh` manually and ensure that all paths are correct. For example:\n```shell\nbash scripts/run_pretraining.sh \\\n 256 6e-3 amp 8 0.2843 7038 200 false 32 0 bert_pretraining \\\n 32 4e-3 0.128 1563 128 \\\n /path/to/dataset/phase1 \\\n /path/to/dataset/phase2 \\\n /workspace/bert \\\n None \\\n /path/to/wikipedia/source \\\n 32 128 4 0.9 64 static \\\n None false\n```\n \nTo run the pre-training routine on an initial checkpoint, point the `from-checkpoint` variable to the location of the checkpoint folder in `scripts/run_pretraining.sh`.\n\nBoth `scripts/run_pretraining.sh` and `scripts/run_squad.sh` rely on positional arguments, which means that if you want to change just one variable from the default value, you need to explicitly specify the values of all variables before it in the argument list, which can be annoying sometimes. Thus, it's also recommended for users to modify the predefined configurations or create their own configuration in `scripts/configs/` folder and run scripts like: `bash scripts/run_pretraining.sh $(source scripts/configs/.sh && )`. \n\nIf users want to move away from bash scripts and launch python scripts directly. It's also recommended to run `run_pretraining.py` and `run_squad.py` with named arguments. For example:\n```shell\npython3 -m paddle.distributed.launch \\\n --gpus=\"0,1,2,3,4,5,6,7\" \\\n ./run_pretraining.py \\\n --input-dir=/path/to/dataset/phase1 \\\n --vocab-file=vocab/bert-large-uncased-vocab.txt \\\n --output-dir=./results \\\n --bert-model=bert-large-uncased \\\n --from-checkpoint=./results/bert-large-uncased/phase1 \\\n --last-step-of-checkpoint=auto \\\n --batch-size=256 \\\n --max-steps=7038 \\\n --num-steps-per-checkpoint=200 \\\n --log-freq=1 \\\n --max-seq-length=128 \\\n --max-predictions-per-seq=20 \\\n --gradient-merge-steps=32 \\\n --amp \\\n --use-dynamic-loss-scaling \\\n --optimizer=Lamb \\\n --phase1 \\\n --scale-loss=1048576 \\\n --learning-rate=6e-3 \\\n --warmup-proportion=0.2843 \\\n --report-file=./results/dllogger_p1.json\n```\nWe provide examples in `scripts/run_pretraining_p1.sh` for phase 1 pre-training and `scripts/run_pretraining_p2.sh` for phase 2 pre-training. For more imformation about each named argument, run `python run_pretraining.py -h` or `python run_squad.py -h`.\n\nNote that:\n- All `` arguments denote the size of a batch computed simultaneously on each GPU. For example, to run phase 1 pretraining on 8xA100, the `` is set to 256 and the `` is set to 32 by default. Each GPU will compute 32 batches before performing a backward/update pass, which means the effective batch size per GPU is `256 * 32 = 8192` and the global batch size is `8192 * #GPUs = 65536`.\n- Checkpoints will be stored in `<--output-dir>/<--bert-model>/<--phase>/` folders.\n\nFor example, to run bert-large-uncased pre-training phase1 for 1000 steps and save checkpoints into `results/bert-large-uncased/phase1` for every 200 steps, set the following args:\n```\n--output-dir results\n--bert-model bert-large-uncased\n--phase1\n--num-steps-per-checkpoint 200\n--max_steps 1000\n```\nThe lastest 3 checkpoints will be saved into `results/bert-large-uncased/phase1/600`, `results/bert-large-uncased/phase1/800` and `results/bert-large-uncased/phase1/1000`.\n\nEach checkpoint includes four files:\n- `<--model-prefix>.pdparams`: A file contains all the trainable tensors.\n- `<--model-prefix>.pdopts`: A file contains all the tensors used by the optimizer. For Adam optimizer, it contains beta1, beta2, momentum, and so on. (If the optimizer has no Tensor need to save (like SGD), no file will be generated).\n- `<--model-prefix>.pdmodel`: A file to keep the description of the program. It's only used for deployment.\n- `<--model-prefix>_progress.json>`: The record of training progress, including file_id, step_id, phase_id, etc.\n\nMake sure:\n- Resume from checkpoints with `--from-checkpoint`: Both `<--model-prefix>.pdopts` and `<--model-prefix>.pdparams` must be in the given path.\n- Start from pre-trained weights with `--from-pretrained-params`: `<--model-prefix>.pdparams` must be in the given path.\n- Don't set `--from-checkpoint` and `--from-pretrained-params` at the same time.\n\nThe difference between those two is that `--from-pretrained-params` contain only model weights, and `--from-checkpoint`, apart from model weights, contain the optimizer state and LR scheduler state.\n\n`--from-checkpoint` is suitable for dividing the training into parts, for example, in order to divide the training job into shorter stages, or restart training after infrastructure faults.\n\n`--from-pretrained-params` can be used to set the initial parameter of phase2 or as a base for fine-tuning the model to a different dataset.\n\nAssume the training process aborts during the 700th step due to infrastructure faults in the previous example, which means the latest checkpoint is saved in `results/bert-large-uncased/phase1/600`. To resume training from the checkpoint, specify `--from-checkpoint` and `--last-step-of-checkpoint` with following these steps: \n- Set `--from-checkpoint` to `results/bert-large-uncased/phase1/600`.\n- Set `--last-step-of-checkpoint` to `600`, which can also be omitted because `results/bert-large-uncased/phase1/600/bert_paddle_progress.json` records the last step id.\nThen rerun the training to resume training from the 601th step to the 1000th step.\n\nWe also provide automatic searching for the checkpoint from the last step. It can be enabled by setting `--last-step-of-checkpoint` as `auto`. Noted that if enable automatic searching, `--from-checkpoint` should be a folder containing checkpoint files or `/`. In the previous example, it should be `results/bert-large-uncased/phase1`.\n\n`--from-phase1-final-params` actually does the same thing as `--from-pretrained-params`. The difference is that the former only works in the first step of phase2, while the latter always works as long as it is set.\n\nAssume you want to train bert-large from scratch however the train progress needs to be restarted many times due to the cluster time limit. To avoid changing `--from-checkpoint` at each run, set the following args:\n- Phase1\n```\n--from-checkpoint results/bert-large-uncased/phase1\n--last-step-of-checkpoint auto\n```\n- Phase2\n```\n--from-checkpoint results/bert-large-uncased/phase2\n--last-step-of-checkpoint auto\n--from-phase1-final-params results/bert-large-uncased/phase1/7038\n```\nAt each rerun, the program will automatically find the checkpoint without having to specify it manually.\n\n#### Fine-tuning\n \nFine-tuning is provided for a variety of tasks. The following tasks are included with this repository through the following scripts (only support SQuAD for now): \n \n- Question Answering (`scripts/run_squad.sh`)\n \nBy default, each Python script implements fine-tuning a pre-trained BERT model for a specified number of training epochs as well as evaluation of the fine-tuned model. Each shell script invokes the associated Python script with the following default parameters:\n \n- Uses 8 GPUs\n- Has FP16 precision enabled\n- Saves a checkpoint at the end of training to the `./results/checkpoints/squad` folder\n \nFine-tuning Python scripts implement support for mixed precision and multi-GPU training. For a full list of parameters and associated explanations, refer to the [Parameters](#parameters) section.\n\nThe fine-tuning shell scripts have positional arguments outlined below:\n \n```shell\nbash scripts/run_squad.sh \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \\\n \n```\n \nBy default, the `mode` argument is set to `train eval`. Refer to the [Quick Start Guide](#quick-start-guide) for explanations of each positional argument.\n \nNote: The first positional argument (the path to the checkpoint to load) is required.\n \nThe fine-tuning script assumes that the corresponding dataset files exist in the `data/` directory or a separate path can be a command-line input to `run_squad.sh`.\n\n### Inference process\n \nFine-tuning inference can be run to obtain predictions on fine-tuning tasks, for example, Q&A on SQuAD. Evaluation fine-tuning is enabled by the same scripts as training:\n \n- Question Answering (`run_squad.py`)\n \nThe `mode` argument of the shell script is used to run in evaluation mode. The fine-tuned BERT model will be run on the evaluation dataset, and the evaluation loss and accuracy will be displayed.\n \nEach inference shell script expects dataset files to exist in the same locations as the corresponding training scripts. The inference scripts can be run with default settings. By setting the `mode` variable in the script to either `eval` or `prediction` flag, you can choose between running predictions and evaluating them on a given dataset or just obtain the model predictions.\n\n`bash scripts/run_squad.sh `","hasAdvanced","performance","### Benchmarking\n \nThe following section shows the steps to run benchmarks measuring the model performance in training and inference modes.\n \n#### Training performance benchmark\n \nTraining performance benchmarks for pre-training can be obtained by running `scripts/run_pretraining.sh`, and fine-tuning can be obtained by running `scripts/run_squad.sh` for SQuAD, respectively. The required parameters can be passed through the command-line as described in [Training process](#training-process).\n\nTo benchmark the training performance on a specific batch size for pre-training, refer to [Pre-training](#pre-training) and turn on the `` flags.

This model is based on the [BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding](https://arxiv.org/abs/1810.04805) paper.\n \nThis repository contains scripts to interactively launch data download, training, benchmarking, and inference routines in a Docker container for pre-training and fine-tuning tasks such as question answering. The major differences between the original implementation of the paper and this version of BERT are as follows:\n \n- Scripts to download the Wikipedia dataset\n- Scripts to preprocess downloaded data into inputs and targets for pre-training in a modular fashion\n- [LAMB](https://arxiv.org/pdf/1904.00962.pdf) optimizer to support training with larger batches\n- Adam optimizer for fine-tuning tasks\n- Automatic mixed precision (AMP) training support\n \nOther publicly available implementations of BERT include:\n1. [NVIDIA PyTorch](https://github.com/NVIDIA/DeepLearningExamples/tree/master/PyTorch/LanguageModeling/BERT)\n2. [NVIDIA TensorFlow](https://github.com/NVIDIA/DeepLearningExamples/tree/master/TensorFlow/LanguageModeling/BERT)\n3. [Hugging Face](https://github.com/huggingface/pytorch-pretrained-BERT)\n4. [codertimo](https://github.com/codertimo/BERT-pytorch)\n5. [gluon-nlp](https://github.com/dmlc/gluon-nlp/tree/v0.10.x/scripts/bert)\n6. [Google's implementation](https://github.com/google-research/bert)\n \nThis model trains with mixed precision Tensor Cores on NVIDIA Ampere and provides a push-button solution to pre-training on a corpus of choice. As a result, researchers can get results 4x faster than training without Tensor Cores. This model is tested against each NGC monthly container release to ensure consistent accuracy and performance over time.\n \n### Model architecture\n \nThe BERT model uses the same architecture as the encoder of the Transformer. Input sequences are projected into an embedding space before being fed into the encoder structure. Additionally, positional and segment encodings are added to the embeddings to preserve positional information. The encoder structure is simply a stack of Transformer blocks, which consist of a multi-head attention layer followed by successive stages of feed-forward networks and layer normalization. The multi-head attention layer accomplishes self-attention on multiple input representations.\n \nAn illustration of the architecture taken from the [Transformer paper](https://arxiv.org/pdf/1706.03762.pdf) is shown below.\n \n ![BERT](https://raw.githubusercontent.com/NVIDIA/DeepLearningExamples/master/PaddlePaddle/LanguageModeling/BERT//images/model.png)\n\n \n### Default configuration\n \nThe architecture of the BERT model is almost identical to the Transformer model that was first introduced in the [Attention Is All You Need paper](https://arxiv.org/pdf/1706.03762.pdf). The main innovation of BERT lies in the pre-training step, where the model is trained on two unsupervised prediction tasks using a large text corpus. Training on these unsupervised tasks produces a generic language model, which can then be quickly fine-tuned to achieve state-of-the-art performance on language processing tasks such as question answering.\n \nThe BERT paper reports the results for two configurations of BERT, each corresponding to a unique model size. This implementation provides the same default configurations, which are described in the table below.\n \n| **Model** | **Hidden layers** | **Hidden unit size** | **Attention heads** | **Feedforward filter size** | **Max sequence length** | **Parameters** |\n|:---------:|:-----------------:|:--------------------:|:-------------------:|:---------------------------:|:-----------------------:|:--------------:|\n| BERTBASE | 12 encoder | 768 | 12 | 4 x 768 | 512 | 110M |\n| BERTLARGE | 24 encoder | 1024 | 16 | 4 x 1024 | 512 | 330M |\n \n### Feature support matrix\n \nThe following features are supported by this model. \n \n| **Feature** | **BERT** |\n|:-----------:|:--------:|\n| [Paddle AMP](https://www.paddlepaddle.org.cn/documentation/docs/en/guides/performance_improving/amp_en.html) | Yes |\n| [Paddle Fleet](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/distributed/fleet/Fleet_en.html#fleet) | Yes |\n| [LAMB](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/optimizer/Lamb_en.html) | Yes |\n| [LDDL](https://github.com/NVIDIA/LDDL) | Yes |\n| Multi-node | Yes |\n \n#### Features\n \n[Fleet](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/distributed/fleet/Fleet_en.html#fleet) is a unified API for distributed training of PaddlePaddle.\n \n[LAMB](https://arxiv.org/pdf/1904.00962.pdf) stands for Layerwise Adaptive Moments based optimizer, which is a large batch optimization technique that helps accelerate the training of deep neural networks using large minibatches. It allows using a global batch size of 65536 and 32768 on sequence lengths 128 and 512, respectively, compared to a batch size of 256 for [Adam](https://arxiv.org/pdf/1412.6980.pdf). The optimized implementation accumulates 1024 gradient batches in phase 1 and 4096 steps in phase 2 before updating weights once. This results in a 15% training speedup. On multi-node systems, LAMB allows scaling up to 1024 GPUs resulting in training speedups of up to 72x in comparison to Adam. Adam has limitations on the learning rate that can be used since it is applied globally on all parameters, whereas LAMB follows a layerwise learning rate strategy.\n\n[LDDL](https://github.com/NVIDIA/LDDL) is a library that enables scalable data preprocessing and loading. LDDL is used by this PaddlePaddle BERT example.\n\n### Mixed precision training\n\nMixed precision is the combined use of different numerical precisions in a computational method. [Mixed precision](https://arxiv.org/abs/1710.03740) training offers significant computational speedup by performing operations in half-precision format while storing minimal information in single-precision to retain as much information as possible in critical parts of the network. Since the introduction of [Tensor Cores](https://developer.nvidia.com/tensor-cores) in NVIDIA Volta, and following with both the NVIDIA Turing and NVIDIA Ampere architectures, significant training speedups are experienced by switching to mixed precision -- up to 3x overall speedup on the most arithmetically intense model architectures. Using mixed precision training requires two steps:\n1. Porting the model to use the FP16 data type where appropriate.\n2. Adding loss scaling to preserve small gradient values.\n\nThe ability to train deep learning networks with lower precision was introduced in the Pascal architecture and first supported in CUDA 8 in the NVIDIA Deep Learning SDK.\n\nFor information about:\n- How to train using mixed precision in PaddlePaddle, refer to the [Mixed Precision Training](https://arxiv.org/abs/1710.03740) paper and [Automatic Mixed Precision Training](https://www.paddlepaddle.org.cn/documentation/docs/en/guides/01_paddle2.0_introduction/basic_concept/amp_en.html#automatic-mixed-precision-training) documentation.\n- Techniques used for mixed precision training, refer to the [Mixed-Precision Training of Deep Neural Networks](https://devblogs.nvidia.com/mixed-precision-training-deep-neural-networks/) blog.\n\n#### Enabling mixed precision\n\nMixed precision is enabled in Paddle by using the Automatic Mixed Precision (AMP) while storing variables in single-precision format. Furthermore, to preserve small gradient magnitudes in backpropagation, a [loss scaling](https://docs.nvidia.com/deeplearning/sdk/mixed-precision-training/index.html#lossscaling) step must be included when applying gradients.\nIn PaddlePaddle, loss scaling can be easily applied by passing in arguments to [GradScaler()](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/amp/GradScaler_en.html). The scaling value to be used can be dynamic or fixed.\n\nFor an in-depth walkthrough on AMP, check out sample usage [here](https://www.paddlepaddle.org.cn/documentation/docs/en/guides/01_paddle2.0_introduction/basic_concept/amp_en.html). Paddle AMP is a PaddlePaddle built-in module that provides functions to construct AMP workflow. The details can be found in [Automatic Mixed Precision (AMP)](https://www.paddlepaddle.org.cn/documentation/docs/en/guides/01_paddle2.0_introduction/basic_concept/amp_en.html#automatic-mixed-precision-training), which requires minimal network code changes to leverage Tensor Cores performance.\n\nCode example to enable mixed precision for static graph:\n- Use `paddle.static.amp.decorate` to wrap optimizer\n ```python\n import paddle.static.amp as amp\n mp_optimizer = amp.decorate(optimizer=optimizer, init_loss_scaling=8.0)\n ```\n- Minimize `loss` , and get `scaled_loss`, which is useful when you need customized loss.\n ```python\n ops, param_grads = mp_optimizer.minimize(loss)\n scaled_loss = mp_optimizer.get_scaled_loss()\n ```\n- For distributed training, it is recommended to use Fleet to enable amp, which is a unified API for distributed training of PaddlePaddle. For more information, refer to [Fleet](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/distributed/fleet/Fleet_en.html#fleet)\n\n ```python\n import paddle.distributed.fleet as fleet\n strategy = fleet.DistributedStrategy()\n strategy.amp = True # by default this is false\n optimizer = fleet.distributed_optimizer(optimizer, strategy=dist_strategy)\n ```\n\n#### Enabling TF32\n\nTensorFloat-32 (TF32) is the new math mode in [NVIDIA A100](https://www.nvidia.com/en-us/data-center/a100/) GPUs for handling the matrix math, also called tensor operations. TF32 running on Tensor Cores in A100 GPUs can provide up to 10x speedups compared to single-precision floating-point math (FP32) on NVIDIA Volta GPUs.\n\nTF32 Tensor Cores can speed up networks using FP32, typically with no loss of accuracy. It is more robust than FP16 for models, which require a high dynamic range for weights or activations.\n\nFor more information, refer to the [TensorFloat-32 in the A100 GPU Accelerates AI Training, HPC up to 20x](https://blogs.nvidia.com/blog/2020/05/14/tensorfloat-32-precision-format/) blog post.\n\nTF32 is supported in the NVIDIA Ampere GPU architecture and is enabled by default.\n\n### Glossary\n \n**Fine-tuning** \nTraining an already pre-trained model further using a task-specific dataset for subject-specific refinements by adding task-specific layers on top if required.\n \n**Language Model** \nAssigns a probability distribution over a sequence of words. Given a sequence of words, it assigns a probability to the whole sequence.\n \n**Pre-training** \nTraining a model on vast amounts of data on the same (or different) task to build general understandings.\n \n**Transformer** \nThe paper [Attention Is All You Need](https://arxiv.org/abs/1706.03762) introduces a novel architecture called Transformer that uses an attention mechanism and transforms one sequence into another.\n \n**Phase 1** \nPre-training on samples of sequence length 128 and 20 masked predictions per sequence.\n \n**Phase 2** \nPre-training on samples of sequence length 512 and 80 masked predictions per sequence.","displayName","BERT for PaddlePaddle",["D",1680632378086],"publisher","NVIDIA Deep Learning Examples","latestVersion","versions","collectionCounts","imageUrl","/api/image/nvidia/dle/resources/bert_paddle","rawImageUrl","https://assets.nvidiagrid.net/ngc/logos/Deep-Learning-Examples.png","canGuestDownload","latestVersionSizeInBytes","licenseTerms","isMultinodeEnabled","isMultiArchitecture","bias","explainability","privacy","safetyAndSecurity","featureLabels",[],"displayLabels",[245],"policyLabels",[],"systemLabels",[],"products",[],"hasNimMetadata",{"_213":246,"_247":248,"_249":250,"_251":252},"Natural Language Understanding","value","uscs_natural_language_understanding","filter",{"_253":254,"_247":248},"category","label","field","application",{"_107":1431,"_109":1432},"ngcApps",[1384],"csaApiBaseUrl","https://www.nvidia.com/ai-agents/csa-agent/dcsm","datadogRum",{"_1365":1366,"_1367":1368,"_1369":1370,"_1371":1372,"_1373":266,"_139":290,"_1374":1375,"_1376":56,"_1377":86,"_1378":86,"_1379":1380,"_1381":86,"_1382":1383},"amplitude",{"_1362":1363,"_963":-7,"_1364":31},"disableJs","environment","prod","featureFlagsBlob","JTdCJTIydGVzdEZsYWclMjIlM0FmYWxzZSUyQyUyMnNob3dTZWFyY2hMYWJlbFNldEZpbHRlcnMlMjIlM0FmYWxzZSUyQyUyMmNoaW5hTmltRGlzdHJpYnV0b3JzUmVkZXNpZ24lMjIlM0F0cnVlJTJDJTIyZW5hYmxlQ3NhV2lkZ2V0JTIyJTNBZmFsc2UlMkMlMjJlbmFibGVQcm9kdWN0R3JvdXBpbmdCeVN1YnNjcmlwdGlvbiUyMiUzQWZhbHNlJTJDJTIyY29udGFpbmVyU2Nhbm5pbmdSZWRlc2lnbk0xJTIyJTNBdHJ1ZSU3RA==","featureFlagsGuarded","isDevLikeEnv","isPlaywright","isMobileDevice","categorizedOrgs",{"_1356":1357,"_1358":1359,"_1360":1361},"currentOrgContext","currentContextRoles",[],"enterpriseOrgs",[],"locale","en","ngcApiOrigin","ngcHelmOrigin","origin","https://catalog.ngc.nvidia.com","usesMocks","theme","year",2026,"1.7.3","defaultSearchSuggestions",{"_1238":370,"_1239":1240,"_1241":1242,"_1243":1244},"announcements",[],"consentState",{"_327":1228,"_1229":86,"_1230":31,"_1231":31,"_1232":1233},"consentConfig",{"_309":310,"_311":312,"_313":314,"_315":316,"_317":318,"_319":320,"_321":322,"_323":324,"_325":326,"_327":328},"showContactAdmin",1783982856431,[],[],[304,305,306,307,308],{"_45":59,"_47":70,"_49":102,"_51":-5,"_53":-5,"_55":56},{"_45":59,"_47":68,"_49":102,"_51":-5,"_53":-5,"_55":56},{"_45":59,"_47":60,"_49":102,"_51":-5,"_53":-5,"_55":56},{"_45":57,"_47":58,"_49":102,"_51":-5,"_53":-5,"_55":56},{"_45":46,"_47":48,"_49":102,"_51":-5,"_53":-5,"_55":56},"mainInfoText","We and our third-party partners (including social media, advertising, and analytics partners) use cookies and other tracking technologies to collect, store, monitor, and process certain information about you when you visit our website.
