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

The ResNet50 v1.5 model is a modified version of the original ResNet50 v1 model.

The difference between v1 and v1.5 is that in the bottleneck blocks which requires\ndownsampling, v1 has stride = 2 in the first 1x1 convolution, whereas v1.5 has stride = 2 in the 3x3 convolution.

This difference makes ResNet50 v1.5 slightly more accurate (~0.5% top1) than v1 but comes with a small performance drawback (~5% imgs/sec).

The model is initialized as described in Delving deep into rectifiers: Surpassing human-level performance on ImageNet classification

This model is trained with mixed precision using Tensor Cores on the NVIDIA Ampere GPU architectures. Therefore, researchers can get results over 2x faster than training without Tensor Cores while experiencing the benefits of mixed precision training. This model is tested against each NGC monthly container release to ensure consistent accuracy and performance over time.

Default configuration

The following sections highlight the default configurations for the ResNet50 model.

Optimizer

This model uses SGD with momentum optimizer with the following hyperparameters:

Momentum (0.875)
Learning rate (LR) = 0.256 for 256 global batch size, for other batch sizes we linearly\nscale the learning rate. For example, default LR = 2.048 for 2048 global batch size on 8xA100. (256 batch size per GPU)
Learning rate schedule - we use cosine LR schedule
Linear warmup of the learning rate during the first 5 epochs according to Training ImageNet in 1 hour.
Weight decay (WD)= 3.0517578125e-05 (1/32768).
We do not apply WD on Batch Norm trainable parameters (gamma/bias)
Label smoothing = 0.1
We train for:\n
- 50 Epochs -> configuration that reaches 75.9% top1 accuracy
- 90 Epochs -> configuration that reaches 76.9% top1 accuracy (90 epochs is a standard for ImageNet networks)
\n

Data augmentation

This model uses the following data augmentation:

For training:\n
- Normalization
- Random resized crop to 224x224\n
  - Scale from 8% to 100%
  - Aspect ratio from 3/4 to 4/3
  \n
- Random horizontal flip
\n
For inference:\n
- Normalization
- Scale to 256x256
- Center crop to 224x224
\n

Other training recipes

This script does not target any specific benchmark.\nThere are changes that others have made which can speed up convergence and/or increase accuracy.

One of the more popular training recipes is provided by fast.ai.

The fast.ai recipe introduces many changes to the training procedure, one of which is progressive resizing of the training images.

The first part of training uses 128px images, the middle part uses 224px images, and the last part uses 288px images.\nThe final validation is performed on 288px images.

The training script in this repository performs validation on 224px images, just like the original paper described.

These two approaches can't be directly compared, since the fast.ai recipe requires validation on 288px images,\nand this recipe keeps the original assumption that validation is done on 224px images.

Using 288px images means that more FLOPs are needed during inference to reach the same accuracy.

Features

\n
NVIDIA DALI - DALI is a library accelerating the data preparation pipeline. To accelerate your input pipeline, you only need to define your data loader\nwith the DALI library. For more information about DALI, refer to the DALI product documentation.
\n
\n
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. Refer to the Enabling mixed precision section for more details.
\n
\n
Paddle ASP is a PaddlePaddle built-in module that provides functions to enable automatic sparsity workflow with only a few code line insertions. The full APIs can be found in Paddle.static.sparsity. Paddle ASP support, currently, static graph mode only (Dynamic graph support is under development). Refer to the Enable Automatic SParsity section for more details.
\n
\n
Paddle-TRT is a PaddlePaddle inference integration with TensorRT. It selects subgraph to be accelerated by TensorRT, while leaving the rest of the operations to be executed natively by PaddlePaddle. Refer to the Inference with TensorRT section for more details.
\n

DALI

We use NVIDIA DALI,\nwhich speeds up data loading when the CPU becomes a bottleneck.\nDALI can use CPU or GPU and outperforms the PaddlePaddle native data loader.

For data loader, we only support DALI as data loader for now.

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)\nwhile 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 walk through 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 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.

Automatic SParsity

Automatic SParsity (ASP) provides a workflow to transfer deep learning models from dense to 2:4 structured sparse, that allows that inference leverage NVIDIA's Sparse Tensor Core, introduced in Ampere architecture, to theoretically reach 2x speedup and save almost 50% memory usage. The workflow of ASP generally includes two steps:

Prune well-trained dense models to 2:4 sparse.
Retrain sparse model with same hyper-parameters to recover accuracy.

For more information, refer to

GTC 2020: Accelerating Sparsity in the NVIDIA Ampere Architecture.
Mishra, Asit, et al. \"Accelerating Sparse Deep Neural Networks.\" arXiv preprint arXiv:2104.08378 (2021).
Pool, Jeff, and Chong Yu. \"Channel Permutations for N: M Sparsity.\" Advances in Neural Information Processing Systems 34 (2021).

Enable Automatic SParsity

There is a built-in module in PaddlePaddle to enable ASP training, which only needs to insert a couple of lines in the original codebase optimizer decoration and model pruning.

optimizer = sparsity.decorate(optimizer)\n...\nsparsity.prune_model(main_program)\n

Moreover, ASP is also compatible with mixed precision training.

Note that currently ASP only supports static graphs (Dynamic graph support is under development).

Clone the repository.\n```bash\ngit clone https://github.com/NVIDIA/DeepLearningExamples.git\ncd DeepLearningExamples/PaddlePaddle/Classification/RN50v1.5\n```\n\n### 2. Download and preprocess the dataset.\n\nThe ResNet50 script operates on ImageNet 1k, a widely popular image classification dataset from the ILSVRC challenge.\n\nPaddle can work directly on JPEGs; therefore, preprocessing/augmentation is not needed.\n\nTo train your model using mixed or TF32 precision with Tensor Cores or using FP32,\nperform the following steps using the default parameters of the resnet50 model on the ImageNet dataset.\nFor the specifics concerning training and inference, refer to the [Advanced](#advanced) section.\n\n1. [Download the images](http://image-net.org/download-images).\n\n2. Extract the training data:\n ```bash\n cd \n mkdir train && mv ILSVRC2012_img_train.tar train/ && cd train\n tar -xvf ILSVRC2012_img_train.tar && rm -f ILSVRC2012_img_train.tar\n find . -name \"*.tar\" | while read NAME ; do mkdir -p \"${NAME%.tar}\"; tar -xvf \"${NAME}\" -C \"${NAME%.tar}\"; rm -f \"${NAME}\"; done\n cd ..\n ```\n\n3. Extract the validation data and move the images to subfolders:\n ```bash\n mkdir val && mv ILSVRC2012_img_val.tar val/ && cd val && tar -xvf ILSVRC2012_img_val.tar\n wget -qO- https://raw.githubusercontent.com/soumith/imagenetloader.torch/master/valprep.sh | bash\n ```\n\nThe directory in which the `train/` and `val/` directories are placed is referred to as `` in this document.\n\n### 3. Build the ResNet50 PaddlePaddle NGC container.\n```bash\ndocker build . -t nvidia_resnet50\n```\n\n### 4. Start an interactive session in the NGC container to run training/inference.\n```bash\nnvidia-docker run --rm -it -v :/imagenet --ipc=host nvidia_resnet50\n```\n\n### 5. Start training\n\nTo run training for a standard configuration (DGXA100, AMP/TF32),\nuse one of scripts in `scripts/training` to launch training. (Please ensure ImageNet is mounted in the `/imagenet` directory.)\n\nExample:\n```bash\n# For TF32 and 8 GPUs training in 90 epochs\nbash scripts/training/train_resnet50_TF32_90E_DGXA100.sh\n\n# For AMP and 8 GPUs training in 90 epochs\nbash scripts/training/train_resnet50_TF32_90E_DGXA100.sh\n```\n\nOr you can manually launch training by `paddle.distributed.launch`. `paddle.distributed.launch` is a built-in module in PaddlePaddle that spawns up multiple distributed training processes on each of the training nodes.\n\nExample:\n```bash\n# For single GPU training with AMP\npython -m paddle.distributed.launch --gpus=0 train.py \\\n --epochs 90 \\\n --amp \\\n --scale-loss 128.0 \\\n --use-dynamic-loss-scaling \\\n --data-layout NHWC\n\n# For 8 GPUs training with AMP\npython -m paddle.distributed.launch --gpus=0,1,2,3,4,5,6,7 train.py \\\n --epochs 90 \\\n --amp \\\n --scale-loss 128.0 \\\n --use-dynamic-loss-scaling \\\n --data-layout NHWC\n```\n\nNote that for initializing training with checkpoints or pretrained parameters, refer to [Training process](#training-process) for more details.\n\n### 6. Start validation/evaluation.\nTo evaluate the validation dataset located in `/imagenet/val`, you need to specify the pretrained weights by `--from-pretrained-params` and set `eval_only` to `--run-scope`.\n\nYou can download pretrained weights from NGC:\n```shell\nwget --content-disposition https://api.ngc.nvidia.com/v2/models/nvidia/dle/resnet_50_paddle_ckpt/versions/22.05.0_amp/zip -O resnet_50_paddle_ckpt_22.05.0_amp.zip\nunzip -d resnet_50_paddle_ckpt_22.05.0_amp.zip\n```\nThis checkpoint is well pretrained on the ImageNet dataset with AMP mode. It achieves 77.11% top 1 accuracy on the test dataset.\n\nExample:\n* TF32\n```bash\n# For single GPU evaluation\npython -m paddle.distributed.launch --gpus=0 train.py \\\n --from-pretrained-params \\\n --run-scope eval_only\n\n# For 8 GPUs evaluation\npython -m paddle.distributed.launch --gpus=0,1,2,3,4,5,6,7 train.py \\\n --from-pretrained-params \\\n --run-scope eval_only\n```\n\n* AMP\n```bash\n# For single GPU evaluation\npython -m paddle.distributed.launch --gpus=0 train.py \\\n --from-pretrained-params \\\n --run-scope eval_only \\\n --amp \\\n --data-layout NHWC\n\n# For 8 GPUs evaluation\npython -m paddle.distributed.launch --gpus=0,1,2,3,4,5,6,7 train.py \\\n --from-pretrained-params \\\n --run-scope eval_only \\\n --amp \\\n --data-layout NHWC\n```\n\nWe also provide scripts to inference with TensorRT that could reach better performance.

For Adam optimizer, it contains beta1, beta2, momentum, and so on. All the information will be saved to a file with suffix \".pdopt\". (If the optimizer has no Tensor need to save (like SGD), the file will not be generated).\n- `.pdmodel`: The network description is the description of the program. It's only used for deployment. The description will save to a file with the suffix \".pdmodel\".\n\nThe prefix of model files is specified by `--model-prefix`, which default value is `resnet_50_paddle`. Model of each epoch would be stored in directory `./output/ResNet50/epoch_id/` with three files by default, including `resnet_50_paddle.pdparams`, `resnet_50_paddle.pdopts`, `resnet_50_paddle.pdmodel`. Note that `epoch_id` is 0-based, which means `epoch_id` is from 0 to 89 for a total of 90 epochs. For example, the model of the 89th epoch would be stored in `./output/ResNet50/89/resnet_50_paddle` \n\nAssume you want to train the ResNet50 for 90 epochs, but the training process aborts during the 50th epoch due to infrastructure faults. To resume training from the checkpoint, specify `--from-checkpoint` and `--last-epoch-of-checkpoint` with following these steps: \n- Set `./output/ResNet50/49` to `--from-checkpoint`.\n- Set `--last-epoch-of-checkpoint` to `49`.\nThen rerun the training to resume training from the 50th epoch to the 89th epoch.\n\nExample:\n```bash\n# Resume AMP training from checkpoint of 50-th epoch\npython -m paddle.distributed.launch --gpus=0,1,2,3,4,5,6,7 train.py \\\n --epochs 90 \\\n --amp \\\n --scale-loss 128.0 \\\n --use-dynamic-loss-scaling \\\n --data-layout NHWC \\\n --model-prefix resnet_50_paddle \\\n --from-checkpoint ./output/ResNet50/49 \\\n --last-epoch-of-checkpoint 49\n```\n\nWe also provide automatic searching for the checkpoint from last epoch. You can enable this by set `--last-epoch-of-checkpoint` as `auto`. Noted that if enable automatic searching, `--from-checkpoint` should be a folder contains chekcpoint files or `/`. In previous example, it should be `./output/ResNet50`.\n\nExample:\n```bash\n# Resume AMP training from checkpoint with automatic searching\npython -m paddle.distributed.launch --gpus=0,1,2,3,4,5,6,7 train.py \\\n --epochs 90 \\\n --amp \\\n --scale-loss 128.0 \\\n --use-dynamic-loss-scaling \\\n --data-layout NHWC \\\n --model-prefix resnet_50_paddle \\\n --from-checkpoint ./output/ResNet50 \\\n --last-epoch-of-checkpoint auto\n```\n\nTo start training from pretrained weights, set `--from-pretrained-params` to `./output/ResNet50//<--model-prefix>`.\n\nExample:\n```bash\n# Train AMP with model initialization by <./your_own_path_to/resnet_50_paddle>\npython -m paddle.distributed.launch --gpus=0,1,2,3,4,5,6,7 train.py \\\n --epochs 90 \\\n --amp \\\n --scale-loss 128.0 \\\n --use-dynamic-loss-scaling \\\n --data-layout NHWC \\\n --model-prefix resnet_50_paddle \\\n --from-pretrained-params ./output/ResNet50/\n```\n\nMake sure:\n- Resume from checkpoints: Both `<--model-prefix>.pdopts` and `<--model-prefix>.pdparams` must be in the given path.\n- Start from pretrained weights: `<--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 as a base for finetuning the model to a different dataset or as a backbone to detection models.\n\nMetrics gathered through both training and evaluation:\n - `[train|val].loss` - loss\n - `[train|val].top1` - top 1 accuracy\n - `[train|val].top5` - top 5 accuracy\n - `[train|val].data_time` - time spent on waiting on data\n - `[train|val].compute_time` - time spent on computing\n - `[train|val].batch_time` - time spent on a mini-batch\n - `[train|val].ips` - speed measured in images per second\n\n Metrics gathered through training only\n - `train.lr` - learning rate\n\n### Automatic SParsity training process:\nTo enable automatic sparsity training workflow, turn on `--amp` and `--prune-mode` when training launches. Refer to [Command-line options](#command-line-options)\n\nNote that automatic sparsity (ASP) requires a pretrained model to initialize parameters.\n\nYou can apply `scripts/training/train_resnet50_AMP_ASP_90E_DGXA100.sh` we provided to launch ASP + AMP training.\n```bash\n# Default path to pretrained parameters is ./output/ResNet50/89/resnet_50_paddle\nbash scripts/training/train_resnet50_AMP_ASP_90E_DGXA100.sh \n```\n\nOr following steps below to manually launch ASP + AMP training.\n\nFirst, set `--from-pretrained-params` to a pretrained model file. For example, if you have trained the ResNet50 for 90 epochs following [Training process](#training-process), the final pretrained weights would be stored in `./output/ResNet50/89/resnet_50_paddle.pdparams` by default, and set `--from-pretrained-params` to `./output/ResNet50/89`.\n\nThen run following command to run AMP + ASP:\n```bash\npython -m paddle.distributed.launch --gpus=0,1,2,3,4,5,6,7 train.py \\\n --from-pretrained-params ./output/ResNet50/89 \\\n --model-prefix resnet_50_paddle \\\n --epochs 90 \\\n --amp \\\n --scale-loss 128.0 \\\n --use-dynamic-loss-scaling \\\n --data-layout NHWC \\\n --asp \\\n --prune-model \\\n --mask-algo mask_1d\n```\n\n### Inference process\n\n#### Inference on your own datasets.\nTo run inference on a single example with pretrained parameters,\n\n1. Set `--from-pretrained-params` to your pretrained parameters.\n2. Set `--image-root` to the root folder of your own dataset. \n - Note that validation dataset should be in `image-root/val`.\n3. Set `--run-scope` to `eval_only`.\n```bash\n# For single GPU evaluation\npython -m paddle.distributed.launch --gpus=0 train.py \\\n --from-pretrained-params \\\n --image-root \\\n --run-scope eval_only\n\n# For 8 GPUs evaluation\npython -m paddle.distributed.launch --gpus=0,1,2,3,4,5,6,7 train.py \\\n --from-pretrained-params \\\n --image-root \\\n --run-scope eval_only\n```\n\n#### Inference with TensorRT\nTo run inference with TensorRT for the best performance, you can apply the scripts in `scripts/inference`.\n\nFor example,\n1. Run `bash scripts/inference/export_resnet50_AMP.sh ` to export an inference model.\n - The default path of checkpoint is `./output/ResNet50/89`.\n2. Run `bash scripts/inference/infer_resnet50_AMP.sh` to infer with TensorRT.\n\nOr you could manually run `export_model.py` and `inference.py` with specific arguments, refer to [Command-line options](#command-line-options).\n\nNote that arguments passed to `export_model.py` and `inference.py` should be the same with arguments used in training.","hasAdvanced","performance","The performance measurements in this document were conducted at the time of publication and may not reflect the performance achieved from NVIDIA's latest software release.

initialization this ResNet50 version gives ~0.5% better accuracy than original.","This resource is using open-source code maintained in github (see the quick-start-guide section) and available for download from [NGC](https://catalog.ngc.nvidia.com/orgs/nvidia/teams/dle/resources/resnet-paddle)\n\nThe ResNet50 v1.5 model is a modified version of the [original ResNet50 v1 model](https://arxiv.org/abs/1512.03385).\n\nThe difference between v1 and v1.5 is that in the bottleneck blocks which requires\ndownsampling, v1 has stride = 2 in the first 1x1 convolution, whereas v1.5 has stride = 2 in the 3x3 convolution.\n\nThis difference makes ResNet50 v1.5 slightly more accurate (\\~0.5% top1) than v1 but comes with a small performance drawback (\\~5% imgs/sec).\n\nThe model is initialized as described in [Delving deep into rectifiers: Surpassing human-level performance on ImageNet classification](https://arxiv.org/pdf/1502.01852.pdf)\n\nThis model is trained with mixed precision using Tensor Cores on the NVIDIA Ampere GPU architectures. Therefore, researchers can get results over 2x faster than training without Tensor Cores while experiencing the benefits of mixed precision training. This model is tested against each NGC monthly container release to ensure consistent accuracy and performance over time.\n\n### Default configuration\n\nThe following sections highlight the default configurations for the ResNet50 model.\n\n#### Optimizer\n\nThis model uses SGD with momentum optimizer with the following hyperparameters:\n\n* Momentum (0.875)\n* Learning rate (LR) = 0.256 for 256 global batch size, for other batch sizes we linearly\nscale the learning rate. For example, default LR = 2.048 for 2048 global batch size on 8xA100. (256 batch size per GPU)\n* Learning rate schedule - we use cosine LR schedule\n* Linear warmup of the learning rate during the first 5 epochs according to [Training ImageNet in 1 hour](https://arxiv.org/abs/1706.02677).\n* Weight decay (WD)= 3.0517578125e-05 (1/32768).\n* We do not apply WD on Batch Norm trainable parameters (gamma/bias)\n* Label smoothing = 0.1\n* We train for: \n * 50 Epochs -> configuration that reaches 75.9% top1 accuracy \n * 90 Epochs -> configuration that reaches 76.9% top1 accuracy (90 epochs is a standard for ImageNet networks)\n\n#### Data augmentation\n\nThis model uses the following data augmentation:\n\n* For training:\n * Normalization\n * Random resized crop to 224x224\n * Scale from 8% to 100%\n * Aspect ratio from 3/4 to 4/3\n * Random horizontal flip\n* For inference:\n * Normalization\n * Scale to 256x256\n * Center crop to 224x224\n\n#### Other training recipes\n\nThis script does not target any specific benchmark.\nThere are changes that others have made which can speed up convergence and/or increase accuracy.\n\nOne of the more popular training recipes is provided by [fast.ai](https://github.com/fastai/imagenet-fast).\n\nThe fast.ai recipe introduces many changes to the training procedure, one of which is progressive resizing of the training images.\n\nThe first part of training uses 128px images, the middle part uses 224px images, and the last part uses 288px images.\nThe final validation is performed on 288px images.\n\nThe training script in this repository performs validation on 224px images, just like the original paper described.\n\nThese two approaches can't be directly compared, since the fast.ai recipe requires validation on 288px images,\nand this recipe keeps the original assumption that validation is done on 224px images.\n\nUsing 288px images means that more FLOPs are needed during inference to reach the same accuracy.\n\n### Feature support matrix\n\nThis model supports the following features:\n\n| Feature | ResNet50\n|-----------------------|--------------------------\n|[DALI](https://docs.nvidia.com/deeplearning/sdk/dali-release-notes/index.html) | Yes |\n|[Paddle AMP](https://www.paddlepaddle.org.cn/documentation/docs/en/guides/performance_improving/amp_en.html) | Yes |\n|[Paddle ASP](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/static/sparsity/decorate_en.html) | Yes |\n|[Paddle-TRT](https://github.com/PaddlePaddle/Paddle-Inference-Demo/blob/master/docs/optimize/paddle_trt_en.rst) | Yes |\n\n#### Features\n\n- NVIDIA DALI - DALI is a library accelerating the data preparation pipeline. To accelerate your input pipeline, you only need to define your data loader\nwith the DALI library. For more information about DALI, refer to the [DALI product documentation](https://docs.nvidia.com/deeplearning/dali/user-guide/docs/index.html).\n\n- 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/performance_improving/amp_en.html#automatic-mixed-precision-training-with-paddlepaddle), which requires minimal network code changes to leverage Tensor Cores performance. Refer to the [Enabling mixed precision](#enabling-mixed-precision) section for more details.\n\n- Paddle ASP is a PaddlePaddle built-in module that provides functions to enable automatic sparsity workflow with only a few code line insertions. The full APIs can be found in [Paddle.static.sparsity](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/static/sparsity/calculate_density_en.html). Paddle ASP support, currently, static graph mode only (Dynamic graph support is under development). Refer to the [Enable Automatic SParsity](#enable-automatic-sparsity) section for more details.\n\n- Paddle-TRT is a PaddlePaddle inference integration with [TensorRT](https://docs.nvidia.com/deeplearning/tensorrt/developer-guide/index.html). It selects subgraph to be accelerated by TensorRT, while leaving the rest of the operations to be executed natively by PaddlePaddle. Refer to the [Inference with TensorRT](#inference-with-tensorrt) section for more details.\n\n### DALI\n\nWe use [NVIDIA DALI](https://github.com/NVIDIA/DALI),\nwhich speeds up data loading when the CPU becomes a bottleneck.\nDALI can use CPU or GPU and outperforms the PaddlePaddle native data loader.\n\nFor data loader, we only support DALI as data loader for now.\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/performance_improving/amp_en.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\n#### Enabling mixed precision\n\nMixed precision is enabled in Paddle by using the Automatic Mixed Precision (AMP) \nwhile 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 walk through on AMP, check out sample usage [here](https://www.paddlepaddle.org.cn/documentation/docs/en/guides/performance_improving/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/performance_improving/amp_en.html#automatic-mixed-precision-training-with-paddlepaddle), 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 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### Automatic SParsity\n\nAutomatic SParsity (ASP) provides a workflow to transfer deep learning models from dense to 2:4 structured sparse, that allows that inference leverage NVIDIA's Sparse Tensor Core, introduced in Ampere architecture, to theoretically reach 2x speedup and save almost 50% memory usage. The workflow of ASP generally includes two steps:\n- Prune well-trained dense models to 2:4 sparse.\n- Retrain sparse model with same hyper-parameters to recover accuracy.\n\nFor more information, refer to\n- [GTC 2020: Accelerating Sparsity in the NVIDIA Ampere Architecture.](https://developer.nvidia.com/gtc/2020/video/s22085#)\n- Mishra, Asit, et al. \"Accelerating Sparse Deep Neural Networks.\" arXiv preprint arXiv:2104.08378 (2021).\n- Pool, Jeff, and Chong Yu. \"Channel Permutations for N: M Sparsity.\" Advances in Neural Information Processing Systems 34 (2021).\n\n#### Enable Automatic SParsity\nThere is a built-in module in PaddlePaddle to enable ASP training, which only needs to insert a couple of lines in the original codebase [optimizer decoration](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/static/sparsity/decorate_en.html) and [model pruning](https://www.paddlepaddle.org.cn/documentation/docs/en/api/paddle/static/sparsity/prune_model_en.html). \n```python\noptimizer = sparsity.decorate(optimizer)\n...\nsparsity.prune_model(main_program)\n```\nMoreover, ASP is also compatible with mixed precision training.\n\nNote that currently ASP only supports static graphs (Dynamic graph support is under development).","displayName","ResNet50 v1.5 for PaddlePaddle",["D",1667524988152],"publisher","NVIDIA Deep Learning Examples","latestVersion","versions","collectionCounts","imageUrl","/api/image/nvidia/dle/resources/resnet_paddle","rawImageUrl","https://assets.nvidiagrid.net/ngc/logos/Deep-Learning-Examples.png","canGuestDownload","latestVersionSizeInBytes","licenseTerms","isMultinodeEnabled","isMultiArchitecture","bias","explainability","privacy","safetyAndSecurity","featureLabels",[],"displayLabels",[],"policyLabels",[],"systemLabels",[],"products",[],"hasNimMetadata",{"_108":1224,"_110":1225},"ngcApps",[1177],"csaApiBaseUrl","https://www.nvidia.com/ai-agents/csa-agent/dcsm","datadogRum",{"_1158":1159,"_1160":1161,"_1162":1163,"_1164":1165,"_1166":257,"_140":283,"_1167":1168,"_1169":56,"_1170":87,"_1171":87,"_1172":1173,"_1174":87,"_1175":1176},"amplitude",{"_1155":1156,"_795":-7,"_1157":31},"disableJs","environment","prod","featureFlagsBlob","JTdCJTIydGVzdEZsYWclMjIlM0FmYWxzZSUyQyUyMnNob3dTZWFyY2hMYWJlbFNldEZpbHRlcnMlMjIlM0FmYWxzZSUyQyUyMmVuYWJsZUNzYVdpZGdldCUyMiUzQWZhbHNlJTJDJTIyZW5hYmxlUHJvZHVjdEdyb3VwaW5nQnlTdWJzY3JpcHRpb24lMjIlM0FmYWxzZSUyQyUyMmNvbnRhaW5lclNjYW5uaW5nUmVkZXNpZ25NMiUyMiUzQWZhbHNlJTdE","featureFlagsGuarded","isDevLikeEnv","isPlaywright","isMobileDevice","categorizedOrgs",{"_1149":1150,"_1151":1152,"_1153":1154},"currentOrgContext","currentContextRoles",[],"enterpriseOrgs",[],"manageableExternalUserGroups",[],"ngcApiOrigin","ngcHelmOrigin","origin","https://catalog.ngc.nvidia.com","usesMocks","theme","year",2026,"now",1787569265566,"1.12.0","defaultSearchSuggestions",{"_1035":362,"_1036":1037,"_1038":1039,"_1040":1041},"announcements",[],"consentState",{"_320":1025,"_1026":87,"_1027":31,"_1028":31,"_1029":1030},"consentConfig",{"_302":303,"_304":305,"_306":307,"_308":309,"_310":311,"_312":313,"_314":315,"_316":317,"_318":319,"_320":321},"showContactAdmin",1787569265571,[],[],[297,298,299,300,301],{"_45":60,"_47":71,"_49":103,"_51":-5,"_53":-5,"_55":56},{"_45":60,"_47":69,"_49":103,"_51":-5,"_53":-5,"_55":56},{"_45":60,"_47":61,"_49":103,"_51":-5,"_53":-5,"_55":56},{"_45":57,"_47":58,"_49":103,"_51":-5,"_53":-5,"_55":56},{"_45":46,"_47":48,"_49":103,"_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.
