BERT, or Bidirectional Encoder Representations from Transformers, 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. NVIDIA's implementation of BERT is an optimized version of the Hugging Face implementation, leveraging mixed precision arithmetic and Tensor Cores on NVIDIA Volta V100 and NVIDIA Ampere A100 GPUs for faster training times while maintaining target accuracy.

This repository contains scripts to interactively launch data download, training, benchmarking, and inference routines in a Docker container for both 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
Fused LAMB optimizer to support training with larger batches
Fused Adam optimizer for fine-tuning tasks
Fused CUDA kernels for better performance LayerNorm
Automatic mixed precision (AMP) training support
Scripts to launch on multiple number of nodes

Other publicly available implementations of BERT include:

This model trains with mixed precision Tensor Cores on NVIDIA Volta 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 configurations by default, which are described in the table below.

Features

APEX is a PyTorch extension with NVIDIA-maintained utilities to streamline mixed precision and distributed training, whereas AMP is an abbreviation used for automatic mixed precision training.

DDP stands for DistributedDataParallel and is used for multi-GPU training.

LAMB stands for Layerwise Adaptive Moments based optimizer, is a large batch optimization technique that helps accelerate 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.

NVLAMB adds the necessary tweaks to LAMB version 1, to ensure correct convergence. The algorithm is as follows:

$\"NVLAMB\"$

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

NVFuser is NVIDIA's fusion backend for PyTorch.

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 the 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.

For information about:

How to train using mixed precision, refer to the Mixed Precision Training paper and Training With Mixed Precision documentation.
Techniques used for mixed precision training, refer to the Mixed-Precision Training of Deep Neural Networks blog.
APEX tools for mixed precision training, refer to the NVIDIA APEX: Tools for Easy Mixed-Precision Training in PyTorch.

Enabling mixed precision

In this repository, mixed precision training is enabled by NVIDIA's APEX library. The APEX library has an automatic mixed precision module that allows mixed precision to be enabled with minimal code changes.

Automatic mixed precision can be enabled with the following code changes:

, loss_scale="dynamic")\n \nif fp16:\n with amp.scale_loss(loss, optimizer) as scaled_loss:\n scaled_loss.backward()\n\">

from apex import amp\nif fp16:\n    # Wrap optimizer and model\n    model, optimizer = amp.initialize(model, optimizer, opt_level=<opt_level>, loss_scale=\"dynamic\")\n \nif fp16:\n    with amp.scale_loss(loss, optimizer) as scaled_loss:\n        scaled_loss.backward()\n

Where <opt_level> is the optimization level. In the pre-training, O2 is set as the optimization level. Mixed precision training can be turned on by passing the fp16 argument to the run_pretraining.py and run_squad.py. All shell scripts have a positional argument available to enable mixed precision training.

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.

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\n`python run_glue.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/DeepLearningExamples/tree/master/PyTorch/LanguageModeling/BERT/../../../Tools/lddl/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- [MRPC](https://www.microsoft.com/en-us/download/details.aspx?id=52398): for paraphrase detection.\n- [SST-2](https://nlp.stanford.edu/sentiment/index.html): for sentiment analysis.\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 the Wikipedia dataset as training data using the LAMB optimizer. By default, the training script runs two phases of training with a hyperparameter recipe specific to 8x V100 32G cards:\n \nPhase 1: (Maximum sequence length of 128)\n- Runs on 8 GPUs with a training batch size of 64 per GPU\n- Uses a learning rate of 6e-3\n- Has FP16 precision 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 a training batch size of 8 per GPU\n- Uses a learning rate of 4e-3\n- Has FP16 precision 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 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 \nThese parameters will train on the Wikipedia dataset to state-of-the-art accuracy on a DGX-1 with 32GB V100 cards.\n \n`bash run_pretraining.sh

Also, to resume pre-training on your corpus of choice, the training dataset should be created using the same vocabulary file used in `data/create_datasets_from_start.sh`.\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:\n \n- Question Answering (`scripts/run_squad.sh`)\n- Paraphrase Detection and Sentiment Analysis (`script/run_glue.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/` folder\n \nFine-tuning Python scripts implement support for mixed precision and multi-GPU training through NVIDIA's [APEX](https://github.com/NVIDIA/apex) library. 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```\n# For SQuAD.\nbash scripts/run_squad.sh \n# For GLUE\nbash scripts/run_glue.sh \n```\n \nBy default, the mode positional 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 \nEach fine-tuning script assumes that the corresponding dataset files exist in the `data/` directory or separate path can be a command-line input to `run_squad.sh`.\n \n### Inference process\n\nFine-tuning inference can be run in order to obtain predictions on fine-tuning tasks, for example, Q&A on SQuAD.\n \n#### Fine-tuning inference\n \nEvaluation fine-tuning is enabled by the same scripts as training:\n \n- Question Answering (`scripts/run_squad.sh`)\n- Paraphrase Detection and Sentiment Analysis (`scripts/run_glue.sh`)\n \nThe mode positional 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 `\n`bash scripts/run_glue.sh `\n\nFor SQuAD, to run inference interactively on question-context pairs, use the script `inference.py` as follows:\n \n`python inference.py --bert_model \"bert-large-uncased\" --init_checkpoint= --config_file=\"bert_config.json\" --vocab_file= --question=\"What food does Harry like?\" --context=\"My name is Harry and I grew up in Canada. I love apples.\"`\n\n### Deploying BERT using NVIDIA Triton Inference Server\n \nThe [NVIDIA Triton Inference Server](https://github.com/NVIDIA/triton-inference-server) provides a cloud inferencing solution optimized for NVIDIA GPUs. The server provides an inference service via an HTTP or GRPC endpoint, allowing remote clients to request inferencing for any model being managed by the server. More information on how to perform inference using NVIDIA Triton Inference Server can be found in [triton/README.md](https://github.com/NVIDIA/DeepLearningExamples/tree/master/PyTorch/LanguageModeling/BERT/./triton/README.md).","hasAdvanced","performance","### Benchmarking\n \nThe following section shows how 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 for fine-tuning can be obtained by running `scripts/run_squad.sh` or `scripts/run_glue.sh` for SQuAD or GLUE, respectively.

This model is based on the [BERT: Pre-training of Deep Bidirectional Transformers for Language Understanding](https://arxiv.org/abs/1810.04805) paper. NVIDIA's implementation of BERT is an optimized version of the [Hugging Face implementation](https://github.com/huggingface/pytorch-pretrained-BERT), leveraging mixed precision arithmetic and Tensor Cores on NVIDIA Volta V100 and NVIDIA Ampere A100 GPUs for faster training times while maintaining target accuracy.\n \nThis repository contains scripts to interactively launch data download, training, benchmarking, and inference routines in a Docker container for both 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- Fused [LAMB](https://arxiv.org/pdf/1904.00962.pdf) optimizer to support training with larger batches\n- Fused Adam optimizer for fine-tuning tasks\n- Fused CUDA kernels for better performance LayerNorm\n- Automatic mixed precision (AMP) training support\n- Scripts to launch on multiple number of nodes\n \nOther publicly available implementations of BERT include:\n1.

[codertimo](https://github.com/codertimo/BERT-pytorch)\n4. [gluon-nlp](https://github.com/dmlc/gluon-nlp/tree/v0.10.x/scripts/bert)\n5. [Google's implementation](https://github.com/google-research/bert)\n \nThis model trains with mixed precision Tensor Cores on NVIDIA Volta 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://github.com/NVIDIA/DeepLearningExamples/raw/master/PyTorch/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 configurations by default, 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| PyTorch AMP | Yes |\n| PyTorch DDP | Yes |\n| LAMB | Yes |\n| Multi-node | Yes |\n| LDDL | Yes |\n| NVFuser | Yes |\n \n#### Features\n \n[APEX](https://github.com/NVIDIA/apex) is a PyTorch extension with NVIDIA-maintained utilities to streamline mixed precision and distributed training, whereas [AMP](https://nvidia.github.io/apex/amp.html) is an abbreviation used for automatic mixed precision training.\n \n[DDP](https://nvidia.github.io/apex/parallel.html) stands for DistributedDataParallel and is used for multi-GPU training.\n \n[LAMB](https://arxiv.org/pdf/1904.00962.pdf) stands for Layerwise Adaptive Moments based optimizer, is a large batch optimization technique that helps accelerate 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 \nNVLAMB adds the necessary tweaks to [LAMB version 1](https://arxiv.org/abs/1904.00962v1), to ensure correct convergence. The algorithm is as follows:\n \n ![NVLAMB](https://github.com/NVIDIA/DeepLearningExamples/raw/master/PyTorch/LanguageModeling/BERT/images/nvlamb.png)\n\n\n[LDDL](../../../Tools/lddl) is a library that enables scalable data preprocessing and loading. LDDL is used by this PyTorch BERT example.\n \nNVFuser is NVIDIA's fusion backend for PyTorch.\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 the 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:\n \n1. Porting the model to use the FP16 data type where appropriate.\n2. Adding loss scaling to preserve small gradient values.\n \nFor information about:\n- How to train using mixed precision, refer to the [Mixed Precision Training](https://arxiv.org/abs/1710.03740) paper and [Training With Mixed Precision](https://docs.nvidia.com/deeplearning/performance/mixed-precision-training/index.html) 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- APEX tools for mixed precision training, refer to the [NVIDIA APEX: Tools for Easy Mixed-Precision Training in PyTorch](https://devblogs.nvidia.com/apex-pytorch-easy-mixed-precision-training/).\n \n#### Enabling mixed precision\n \nIn this repository, mixed precision training is enabled by NVIDIA's APEX library. The APEX library has an automatic mixed precision module that allows mixed precision to be enabled with minimal code changes.\n \nAutomatic mixed precision can be enabled with the following code changes:\n \n```\nfrom apex import amp\nif fp16:\n # Wrap optimizer and model\n model, optimizer = amp.initialize(model, optimizer, opt_level=, loss_scale=\"dynamic\")\n \nif fp16:\n with amp.scale_loss(loss, optimizer) as scaled_loss:\n scaled_loss.backward()\n ```\n \nWhere `` is the optimization level. In the pre-training, `O2` is set as the optimization level. Mixed precision training can be turned on by passing the `fp16` argument to the `run_pretraining.py` and `run_squad.py`. All shell scripts have a positional argument available to enable mixed precision training.\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 PyTorch",["D",1680631551806],"publisher","NVIDIA Deep Learning Examples","latestVersion","versions","collectionCounts","imageUrl","/api/image/nvidia/-/resources/bert_for_pytorch","rawImageUrl","https://assets.nvidiagrid.net/ngc/logos/Deep-Learning-Examples.png","canGuestDownload","latestVersionSizeInBytes",7492644,"licenseTerms","isMultinodeEnabled","isMultiArchitecture","bias","explainability","privacy","safetyAndSecurity","featureLabels",[],"displayLabels",[281,282],"policyLabels",[],"systemLabels",[],"products",[],"hasNimMetadata",{"_248":292,"_284":293,"_286":294,"_288":289},{"_248":283,"_284":285,"_286":287,"_288":289},"Natural Language Understanding","value","uscs_natural_language_understanding","filter",{"_290":291,"_284":285},"category","label","field","application","Deep Learning Examples","pltfm_deep_learning_examples",{"_290":295,"_284":293},"platform",{"_87":1484,"_89":1485},"ngcApps",[1437],"csaApiBaseUrl","https://www.nvidia.com/ai-agents/csa-agent/dcsm","datadogRum",{"_1419":1420,"_1421":1422,"_1423":1424,"_1425":1426,"_1427":307,"_114":331,"_1428":1429,"_1417":50,"_1430":66,"_1431":66,"_1432":1433,"_1434":66,"_1435":1436},"amplitude",{"_1415":1416,"_1417":50,"_1006":-7,"_1418":26},"disableJs","environment","prod","featureFlagsBlob","JTdCJTIydGVzdEZsYWclMjIlM0FmYWxzZSUyQyUyMnNob3dTZWFyY2hMYWJlbFNldEZpbHRlcnMlMjIlM0FmYWxzZSUyQyUyMmNoaW5hTmltRGlzdHJpYnV0b3JzUmVkZXNpZ24lMjIlM0F0cnVlJTJDJTIyZW5hYmxlQ3NhV2lkZ2V0JTIyJTNBZmFsc2UlMkMlMjJlbmFibGVQcm9kdWN0R3JvdXBpbmdCeVN1YnNjcmlwdGlvbiUyMiUzQWZhbHNlJTJDJTIyY29udGFpbmVyU2Nhbm5pbmdSZWRlc2lnbk0xJTIyJTNBZmFsc2UlN0Q=","featureFlagsGuarded","isDevLikeEnv","isPlaywright","isMobileDevice","categorizedOrgs",{"_1409":1410,"_1411":1412,"_1413":1414},"currentOrgContext","currentContextRoles",[],"enterpriseOrgs",[],"locale","en","ngcApiOrigin","ngcHelmOrigin","origin","https://catalog.ngc.nvidia.com","usesMocks","theme","year",2026,"1.4.0","defaultSearchSuggestions",{"_1281":412,"_1282":1283,"_1284":1285,"_1286":1287},"announcements",[],"consentState",{"_369":1271,"_1272":66,"_1273":26,"_1274":26,"_1275":1276},"consentConfig",{"_351":352,"_353":354,"_355":356,"_357":358,"_359":360,"_361":362,"_363":364,"_365":366,"_367":368,"_369":370},"showContactAdmin",1782610601044,[],[],[345,346,347,348,349,350],{"_39":54,"_41":63,"_43":82,"_45":-5,"_47":-5,"_49":50},{"_39":54,"_41":61,"_43":82,"_45":-5,"_47":-5,"_49":50},{"_39":54,"_41":59,"_43":82,"_45":-5,"_47":-5,"_49":50},{"_39":54,"_41":55,"_43":82,"_45":-5,"_47":-5,"_49":50},{"_39":51,"_41":52,"_43":82,"_45":-5,"_47":-5,"_49":50},{"_39":40,"_41":42,"_43":82,"_45":-5,"_47":-5,"_49":50},"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.
