## What's New

❗Updates after Oct 10, 2022 are available in version >= 0.9❗
* Many changes since the last 0.6.x stable releases. They were previewed in 0.8.x dev releases but not everyone transitioned.
* `timm.models.layers` moved to `timm.layers`:
  * `from timm.models.layers import name` will still work via deprecation mapping (but please transition to `timm.layers`).
  * `import timm.models.layers.module` or `from timm.models.layers.module import name` needs to be changed now.
* Builder, helper, non-model modules in `timm.models` have a `_` prefix added, ie `timm.models.helpers` -> `timm.models._helpers`, there are temporary deprecation mapping files but those will be removed.
* All models now support `architecture.pretrained_tag` naming (ex `resnet50.rsb_a1`).
  * The pretrained_tag is the specific weight variant (different head) for the architecture.
  * Using only `architecture` defaults to the first weights in the default_cfgs for that model architecture.
  * In adding pretrained tags, many model names that existed to differentiate were renamed to use the tag  (ex: `vit_base_patch16_224_in21k` -> `vit_base_patch16_224.augreg_in21k`). There are deprecation mappings for these.
* A number of models had their checkpoints remaped to match architecture changes needed to better support `features_only=True`, there are `checkpoint_filter_fn` methods in any model module that was remapped. These can be passed to `timm.models.load_checkpoint(..., filter_fn=timm.models.swin_transformer_v2.checkpoint_filter_fn)` to remap your existing checkpoint.
* The Hugging Face Hub (https://huggingface.co/timm) is now the primary source for `timm` weights. Model cards include link to papers, original source, license. 
* Previous 0.6.x can be cloned from [0.6.x](https://github.com/rwightman/pytorch-image-models/tree/0.6.x) branch or installed via pip with version.

### Jan 8, 2024
Datasets & transform refactoring
* HuggingFace streaming (iterable) dataset support (`--dataset hfids:org/dataset`)
* Webdataset wrapper tweaks for improved split info fetching, can auto fetch splits from supported HF hub webdataset
* Tested HF `datasets` and webdataset wrapper streaming from HF hub with recent `timm` ImageNet uploads to https://huggingface.co/timm
* Make input & target column/field keys consistent across datasets and pass via args
* Full monochrome support when using e:g: `--input-size 1 224 224` or `--in-chans 1`, sets PIL image conversion appropriately in dataset
* Improved several alternate crop & resize transforms (ResizeKeepRatio, RandomCropOrPad, etc) for use in PixParse document AI project
* Add SimCLR style color jitter prob along with grayscale and gaussian blur options to augmentations and args
* Allow train without validation set (`--val-split ''`) in train script
* Add `--bce-sum` (sum over class dim) and `--bce-pos-weight` (positive weighting) args for training as they're common BCE loss tweaks I was often hard coding 

### Nov 23, 2023
* Added EfficientViT-Large models, thanks [SeeFun](https://github.com/seefun)
* Fix Python 3.7 compat, will be dropping support for it soon
* Other misc fixes
* Release 0.9.12

### Nov 20, 2023
* Added significant flexibility for Hugging Face Hub based timm models via `model_args` config entry. `model_args` will be passed as kwargs through to models on creation. 
  * See example at https://huggingface.co/gaunernst/vit_base_patch16_1024_128.audiomae_as2m_ft_as20k/blob/main/config.json
  * Usage: https://github.com/huggingface/pytorch-image-models/discussions/2035
* Updated imagenet eval and test set csv files with latest models
* `vision_transformer.py` typing and doc cleanup by [Laureηt](https://github.com/Laurent2916)
* 0.9.11 release

### Nov 3, 2023
* [DFN (Data Filtering Networks)](https://huggingface.co/papers/2309.17425) and [MetaCLIP](https://huggingface.co/papers/2309.16671) ViT weights added
* DINOv2 'register' ViT model weights added (https://huggingface.co/papers/2309.16588, https://huggingface.co/papers/2304.07193)
* Add `quickgelu` ViT variants for OpenAI, DFN, MetaCLIP weights that use it (less efficient)
* Improved typing added to ResNet, MobileNet-v3 thanks to [Aryan](https://github.com/a-r-r-o-w)
* ImageNet-12k fine-tuned (from LAION-2B CLIP) `convnext_xxlarge`
* 0.9.9 release

### Oct 20, 2023
* [SigLIP](https://huggingface.co/papers/2303.15343) image tower weights supported in `vision_transformer.py`.
  * Great potential for fine-tune and downstream feature use.
* Experimental 'register' support in vit models as per [Vision Transformers Need Registers](https://huggingface.co/papers/2309.16588)
* Updated RepViT with new weight release. Thanks [wangao](https://github.com/jameslahm)
* Add patch resizing support (on pretrained weight load) to Swin models
* 0.9.8 release pending

### Sep 1, 2023
* TinyViT added by [SeeFun](https://github.com/seefun)
* Fix EfficientViT (MIT) to use torch.autocast so it works back to PT 1.10
* 0.9.7 release

### Aug 28, 2023
* Add dynamic img size support to models in `vision_transformer.py`, `vision_transformer_hybrid.py`, `deit.py`, and `eva.py` w/o breaking backward compat.
  * Add `dynamic_img_size=True` to args at model creation time to allow changing the grid size (interpolate abs and/or ROPE pos embed each forward pass).
  * Add `dynamic_img_pad=True` to allow image sizes that aren't divisible by patch size (pad bottom right to patch size each forward pass).
  * Enabling either dynamic mode will break FX tracing unless PatchEmbed module added as leaf.
  * Existing method of resizing position embedding by passing different `img_size` (interpolate pretrained embed weights once) on creation still works.
  * Existing method of changing `patch_size` (resize pretrained patch_embed weights once) on creation still works.
  * Example validation cmd `python validate.py /imagenet --model vit_base_patch16_224 --amp --amp-dtype bfloat16 --img-size 255 --crop-pct 1.0 --model-kwargs dynamic_img_size=True dyamic_img_pad=True`

* Multi-weight and HF hub for DeiT and MLP-Mixer based models

### March 22, 2023
* More weights pushed to HF hub along with multi-weight support, including: `regnet.py`, `rexnet.py`, `byobnet.py`, `resnetv2.py`, `swin_transformer.py`, `swin_transformer_v2.py`, `swin_transformer_v2_cr.py`
* Swin Transformer models support feature extraction (NCHW feat maps for `swinv2_cr_*`, and NHWC for all others) and spatial embedding outputs.
* FocalNet (from https://github.com/microsoft/FocalNet) models and weights added with significant refactoring, feature extraction, no fixed resolution / sizing constraint
* RegNet weights increased with HF hub push, SWAG, SEER, and torchvision v2 weights. SEER is pretty poor wrt to performance for model size, but possibly useful.
* More ImageNet-12k pretrained and 1k fine-tuned `timm` weights:
  * `rexnetr_200.sw_in12k_ft_in1k` - 82.6 @ 224, 83.2 @ 288

### Jan 11, 2023
* Update ConvNeXt ImageNet-12k pretrain series w/ two new fine-tuned weights (and pre FT `.in12k` tags)
  * `convnext_nano.in12k_ft_in1k` - 82.3 @ 224, 82.9 @ 288  (previously released)
  * `convnext_tiny.in12k_ft_in1k` - 84.2 @ 224, 84.5 @ 288
  * `convnext_small.in12k_ft_in1k` - 85.2 @ 224, 85.3 @ 288

### Jan 6, 2023
* Finally got around to adding `--model-kwargs` and `--opt-kwargs` to scripts to pass through rare args directly to model classes from cmd line
  * `train.py /imagenet --model resnet50 --amp --model-kwargs output_stride=16 act_layer=silu`
  * `train.py /imagenet --model vit_base_patch16_clip_224 --img-size 240 --amp --model-kwargs img_size=240 patch_size=12`
* Cleanup some popular models to better support arg passthrough / merge with model configs, more to go.

### Jan 5, 2023
* ConvNeXt-V2 models and weights added to existing `convnext.py`
  * Paper: [ConvNeXt V2: Co-designing and Scaling ConvNets with Masked Autoencoders](http://arxiv.org/abs/2301.00808)
  * Reference impl: https://github.com/facebookresearch/ConvNeXt-V2 (NOTE: weights currently CC-BY-NC)

### Dec 23, 2022 🎄☃
* Add FlexiViT models and weights from https://github.com/google-research/big_vision (check out paper at https://arxiv.org/abs/2212.08013)
  * NOTE currently resizing is static on model creation, on-the-fly dynamic / train patch size sampling is a WIP
* Many more models updated to multi-weight and downloadable via HF hub now (convnext, efficientnet, mobilenet, vision_transformer*, beit)
* More model pretrained tag and adjustments, some model names changed (working on deprecation translations, consider main branch DEV branch right now, use 0.6.x for stable use)
* More ImageNet-12k (subset of 22k) pretrain models popping up:
  * `efficientnet_b5.in12k_ft_in1k` - 85.9 @ 448x448
  * `vit_medium_patch16_gap_384.in12k_ft_in1k` - 85.5 @ 384x384
  * `vit_medium_patch16_gap_256.in12k_ft_in1k` - 84.5 @ 256x256
  * `convnext_nano.in12k_ft_in1k` - 82.9 @ 288x288

### Dec 8, 2022
* Add 'EVA l' to `vision_transformer.py`, MAE style ViT-L/14 MIM pretrain w/ EVA-CLIP targets, FT on ImageNet-1k (w/ ImageNet-22k intermediate for some)

### Dec 5, 2022

* Pre-release (`0.8.0dev0`) of multi-weight support (`model_arch.pretrained_tag`). Install with `pip install --pre timm`
  * vision_transformer, maxvit, convnext are the first three model impl w/ support
  * model names are changing with this (previous _21k, etc. fn will merge), still sorting out deprecation handling
  * bugs are likely, but I need feedback so please try it out
  * if stability is needed, please use 0.6.x pypi releases or clone from [0.6.x branch](https://github.com/rwightman/pytorch-image-models/tree/0.6.x)
* Support for PyTorch 2.0 compile is added in train/validate/inference/benchmark, use `--torchcompile` argument
* Inference script allows more control over output, select k for top-class index + prob json, csv or parquet output
* Add a full set of fine-tuned CLIP image tower weights from both LAION-2B and original OpenAI CLIP models

* Port of MaxViT Tensorflow Weights from official impl at https://github.com/google-research/maxvit
  * There was larger than expected drops for the upscaled 384/512 in21k fine-tune weights, possible detail missing, but the 21k FT did seem sensitive to small preprocessing

### Oct 15, 2022
* Train and validation script enhancements
* Non-GPU (ie CPU) device support
* SLURM compatibility for train script
* HF datasets support (via ReaderHfds)
* TFDS/WDS dataloading improvements (sample padding/wrap for distributed use fixed wrt sample count estimate)
* in_chans !=3 support for scripts / loader
* Adan optimizer
* Can enable per-step LR scheduling via args
* Dataset 'parsers' renamed to 'readers', more descriptive of purpose
* AMP args changed, APEX via `--amp-impl apex`, bfloat16 supportedf via `--amp-dtype bfloat16`
* main branch switched to 0.7.x version, 0.6x forked for stable release of weight only adds
* master -> main branch rename

### Oct 10, 2022
* More weights in `maxxvit` series, incl first ConvNeXt block based `coatnext` and `maxxvit` experiments:
  * `coatnext_nano_rw_224` - 82.0 @ 224 (G) -- (uses ConvNeXt conv block, no BatchNorm)
  * `maxxvit_rmlp_nano_rw_256` - 83.0 @ 256, 83.7 @ 320  (G) (uses ConvNeXt conv block, no BN)
  * `maxvit_rmlp_small_rw_224` - 84.5 @ 224, 85.1 @ 320 (G)
  * `maxxvit_rmlp_small_rw_256` - 84.6 @ 256, 84.9 @ 288 (G) -- could be trained better, hparams need tuning (uses ConvNeXt block, no BN)
  * `coatnet_rmlp_2_rw_224` - 84.6 @ 224, 85 @ 320  (T)
  * NOTE: official MaxVit weights (in1k) have been released at https://github.com/google-research/maxvit -- some extra work is needed to port and adapt since my impl was created independently of theirs and has a few small differences + the whole TF same padding fun.

### Sept 23, 2022
* LAION-2B CLIP image towers supported as pretrained backbones for fine-tune or features (no classifier)
  * vit_base_patch32_224_clip_laion2b
  * vit_large_patch14_224_clip_laion2b
  * vit_huge_patch14_224_clip_laion2b
  * vit_giant_patch14_224_clip_laion2b

### Sept 7, 2022
* Hugging Face [`timm` docs](https://huggingface.co/docs/hub/timm) home now exists, look for more here in the future
* Add BEiT-v2 weights for base and large 224x224 models from https://github.com/microsoft/unilm/tree/master/beit2
* Add more weights in `maxxvit` series incl a `pico` (7.5M params, 1.9 GMACs), two `tiny` variants:
  * `maxvit_rmlp_pico_rw_256` - 80.5 @ 256, 81.3 @ 320  (T)
  * `maxvit_tiny_rw_224` - 83.5 @ 224 (G)
  * `maxvit_rmlp_tiny_rw_256` - 84.2 @ 256, 84.8 @ 320 (T)


## Introduction

Py**T**orch **Im**age **M**odels (`timm`) is a collection of image models, layers, utilities, optimizers, schedulers, data-loaders / augmentations, and reference training / validation scripts that aim to pull together a wide variety of SOTA models with ability to reproduce ImageNet training results.

The work of many others is present here. I've tried to make sure all source material is acknowledged via links to github, arxiv papers, etc in the README, documentation, and code docstrings. Please let me know if I missed anything.

## Models

All model architecture families include variants with pretrained weights. There are specific model variants without any weights, it is NOT a bug. Help training new or better weights is always appreciated.

## Features

Several (less common) features that I often utilize in my projects are included. Many of their additions are the reason why I maintain my own set of models, instead of using others' via PIP:

* All models have a common default configuration interface and API for
    * accessing/changing the classifier - `get_classifier` and `reset_classifier`
    * doing a forward pass on just the features - `forward_features` (see [documentation](https://huggingface.co/docs/timm/feature_extraction))
    * these makes it easy to write consistent network wrappers that work with any of the models
* All models support multi-scale feature map extraction (feature pyramids) via create_model (see [documentation](https://huggingface.co/docs/timm/feature_extraction))
    * `create_model(name, features_only=True, out_indices=..., output_stride=...)`
    * `out_indices` creation arg specifies which feature maps to return, these indices are 0 based and generally correspond to the `C(i + 1)` feature level.
    * `output_stride` creation arg controls output stride of the network by using dilated convolutions. Most networks are stride 32 by default. Not all networks support this.
    * feature map channel counts, reduction level (stride) can be queried AFTER model creation via the `.feature_info` member
* All models have a consistent pretrained weight loader that adapts last linear if necessary, and from 3 to 1 channel input if desired
* High performance [reference training, validation, and inference scripts](https://huggingface.co/docs/timm/training_script) that work in several process/GPU modes:
    * NVIDIA DDP w/ a single GPU per process, multiple processes with APEX present (AMP mixed-precision optional)
    * PyTorch DistributedDataParallel w/ multi-gpu, single process (AMP disabled as it crashes when enabled)
    * PyTorch w/ single GPU single process (AMP optional)
* A dynamic global pool implementation that allows selecting from average pooling, max pooling, average + max, or concat([average, max]) at model creation. All global pooling is adaptive average by default and compatible with pretrained weights.
* A 'Test Time Pool' wrapper that can wrap any of the included models and usually provides improved performance doing inference with input images larger than the training size. Idea adapted from original DPN implementation when I ported (https://github.com/cypw/DPNs)
* Learning rate schedulers
  * Ideas adopted from
     * [AllenNLP schedulers](https://github.com/allenai/allennlp/tree/master/allennlp/training/learning_rate_schedulers)
     * [FAIRseq lr_scheduler](https://github.com/pytorch/fairseq/tree/master/fairseq/optim/lr_scheduler)
     * SGDR: Stochastic Gradient Descent with Warm Restarts (https://arxiv.org/abs/1608.03983)
  * Schedulers include `step`, `cosine` w/ restarts, `tanh` w/ restarts, `plateau`
* Optimizers:
    * `rmsprop_tf` adapted from PyTorch RMSProp by myself. Reproduces much improved Tensorflow RMSProp behaviour.
    * `radam` by [Liyuan Liu](https://github.com/LiyuanLucasLiu/RAdam) (https://arxiv.org/abs/1908.03265)
    * `novograd` by [Masashi Kimura](https://github.com/convergence-lab/novograd) (https://arxiv.org/abs/1905.11286)
    * `lookahead` adapted from impl by [Liam](https://github.com/alphadl/lookahead.pytorch) (https://arxiv.org/abs/1907.08610)
    * `fused<name>` optimizers by name with [NVIDIA Apex](https://github.com/NVIDIA/apex/tree/master/apex/optimizers) installed
    * `adamp` and `sgdp` by [Naver ClovAI](https://github.com/clovaai) (https://arxiv.org/abs/2006.08217)
    * `adafactor` adapted from [FAIRSeq impl](https://github.com/pytorch/fairseq/blob/master/fairseq/optim/adafactor.py) (https://arxiv.org/abs/1804.04235)
    * `adahessian` by [David Samuel](https://github.com/davda54/ada-hessian) (https://arxiv.org/abs/2006.00719)
* Random Erasing from [Zhun Zhong](https://github.com/zhunzhong07/Random-Erasing/blob/master/transforms.py)  (https://arxiv.org/abs/1708.04896)
* Mixup (https://arxiv.org/abs/1710.09412)
* CutMix (https://arxiv.org/abs/1905.04899)
* AutoAugment (https://arxiv.org/abs/1805.09501) and RandAugment (https://arxiv.org/abs/1909.13719) ImageNet configurations modeled after impl for EfficientNet training (https://github.com/tensorflow/tpu/blob/master/models/official/efficientnet/autoaugment.py)
* AugMix w/ JSD loss (https://arxiv.org/abs/1912.02781), JSD w/ clean + augmented mixing support works with AutoAugment and RandAugment as well
* SplitBachNorm - allows splitting batch norm layers between clean and augmented (auxiliary batch norm) data

## Getting Started (Documentation)

The official documentation can be found at https://huggingface.co/docs/hub/timm. Documentation contributions are welcome.

[Getting Started with PyTorch Image Models (timm): A Practitioner’s Guide](https://towardsdatascience.com/getting-started-with-pytorch-image-models-timm-a-practitioners-guide-4e77b4bf9055) by [Chris Hughes](https://github.com/Chris-hughes10) is an extensive blog post covering many aspects of `timm` in detail.

[timmdocs](http://timm.fast.ai/) is an alternate set of documentation for `timm`. A big thanks to [Aman Arora](https://github.com/amaarora) for his efforts creating timmdocs.

[paperswithcode](https://paperswithcode.com/lib/timm) is a good resource for browsing the models within `timm`.

## Train, Validation, Inference Scripts

The root folder of the repository contains reference train, validation, and inference scripts that work with the included models and other features of this repository. They are adaptable for other datasets and use cases with a little hacking. See [documentation](https://huggingface.co/docs/timm/training_script).

## Licenses

### Code
The code here is licensed Apache 2.0. I've taken care to make sure any third party code included or adapted has compatible (permissive) licenses such as MIT, BSD, etc. I've made an effort to avoid any GPL / LGPL conflicts. That said, it is your responsibility to ensure you comply with licenses here and conditions of any dependent licenses. Where applicable, I've linked the sources/references for various components in docstrings. If you think I've missed anything please create an issue.

### Pretrained Weights
So far all of the pretrained weights available here are pretrained on ImageNet with a select few that have some additional pretraining (see extra note below). ImageNet was released for non-commercial research purposes only (https://image-net.org/download). It's not clear what the implications of that are for the use of pretrained weights from that dataset. Any models I have trained with ImageNet are done for research purposes and one should assume that the original dataset license applies to the weights. It's best to seek legal advice if you intend to use the pretrained weights in a commercial product.

#### Pretrained on more than ImageNet
Several weights included or references here were pretrained with proprietary datasets that I do not have access to. These include the Facebook WSL, SSL, SWSL ResNe(Xt) and the Google Noisy Student EfficientNet models. The Facebook models have an explicit non-commercial license (CC-BY-NC 4.0, https://github.com/facebookresearch/semi-supervised-ImageNet1K-models, https://github.com/facebookresearch/WSL-Images). The Google models do not appear to have any restriction beyond the Apache 2.0 license (and ImageNet concerns). In either case, you should contact Facebook or Google with any questions.

They were previewed in 0.8.x dev releases but not everyone transitioned.\n* `timm.models.layers` moved to `timm.layers`:\n  * `from timm.models.layers import name` will still work via deprecation mapping (but please transition to `timm.layers`).\n  * `import timm.models.layers.module` or `from timm.models.layers.module import name` needs to be changed now.\n* Builder, helper, non-model modules in `timm.models` have a `_` prefix added, ie `timm.models.helpers` -> `timm.models._helpers`, there are temporary deprecation mapping files but those will be removed.\n* All models now support `architecture.pretrained_tag` naming (ex `resnet50.rsb_a1`).\n  * The pretrained_tag is the specific weight variant (different head) for the architecture.\n  * Using only `architecture` defaults to the first weights in the default_cfgs for that model architecture.\n  * In adding pretrained tags, many model names that existed to differentiate were renamed to use the tag  (ex: `vit_base_patch16_224_in21k` -> `vit_base_patch16_224.augreg_in21k`). There are deprecation mappings for these.\n* A number of models had their checkpoints remaped to match architecture changes needed to better support `features_only=True`, there are `checkpoint_filter_fn` methods in any model module that was remapped. These can be passed to `timm.models.load_checkpoint(..., filter_fn=timm.models.swin_transformer_v2.checkpoint_filter_fn)` to remap your existing checkpoint.\n* The Hugging Face Hub (https://huggingface.co/timm) is now the primary source for `timm` weights.

train script\n* HF datasets support (via ReaderHfds)\n* TFDS/WDS dataloading improvements (sample padding/wrap for distributed use fixed wrt sample count estimate)\n* in_chans !=3 support for scripts / loader\n* Adan optimizer\n* Can enable per-step LR scheduling via args\n* Dataset 'parsers' renamed to 'readers', more descriptive of purpose\n* AMP args changed, APEX via `--amp-impl apex`, bfloat16 supportedf via `--amp-dtype bfloat16`\n* main branch switched to 0.7.x version, 0.6x forked for stable release of weight only adds\n* master -> main branch rename\n\n### Oct 10, 2022\n* More weights in `maxxvit` series, incl first ConvNeXt block based `coatnext` and `maxxvit` experiments:\n  * `coatnext_nano_rw_224` - 82.0 @ 224 (G) -- (uses ConvNeXt conv block, no BatchNorm)\n  * `maxxvit_rmlp_nano_rw_256` - 83.0 @ 256, 83.7 @ 320  (G) (uses ConvNeXt conv block, no BN)\n  * `maxvit_rmlp_small_rw_224` - 84.5 @ 224, 85.1 @ 320 (G)\n  * `maxxvit_rmlp_small_rw_256` - 84.6 @ 256, 84.9 @ 288 (G) -- could be trained better, hparams need tuning (uses ConvNeXt block, no BN)\n  * `coatnet_rmlp_2_rw_224` - 84.6 @ 224, 85 @ 320  (T)\n  * NOTE: official MaxVit weights (in1k) have been released at https://github.com/google-research/maxvit -- some extra work is needed to port and adapt since my impl was created independently of theirs and has a few small differences + the whole TF same padding fun.\n\n### Sept 23, 2022\n* LAION-2B CLIP image towers supported as pretrained backbones for fine-tune or features (no classifier)\n  * vit_base_patch32_224_clip_laion2b\n  *

https://github.com/microsoft/unilm/tree/master/beit2\n* Add more weights in `maxxvit` series incl a `pico` (7.5M params, 1.9 GMACs), two `tiny` variants:\n  * `maxvit_rmlp_pico_rw_256` - 80.5 @ 256, 81.3 @ 320  (T)\n  * `maxvit_tiny_rw_224` - 83.5 @ 224 (G)\n  * `maxvit_rmlp_tiny_rw_256` - 84.2 @ 256, 84.8 @ 320 (T)\n\n\n## Introduction\n\nPy**T**orch **Im**age **M**odels (`timm`) is a collection of image models, layers, utilities, optimizers, schedulers, data-loaders / augmentations, and reference training / validation scripts that aim to pull together a wide variety of SOTA models with ability to reproduce ImageNet training results.\n\nThe work of many others is present here. I've tried to make sure all source material is acknowledged via links to github, arxiv papers, etc in the README, documentation, and code docstrings. Please let me know if I missed anything.\n\n## Models\n\nAll model architecture families include variants with pretrained weights. There are specific model variants without any weights, it is NOT a bug. Help training new or better weights is always appreciated.\n\n* Aggregating Nested Transformers - https://arxiv.org/abs/2105.12723\n* BEiT - https://arxiv.org/abs/2106.08254\n* Big Transfer ResNetV2 (BiT) -

Many of their additions are the reason why I maintain my own set of models, instead of using others' via PIP:\n\n* All models have a common default configuration interface and API for\n    * accessing/changing the classifier - `get_classifier` and `reset_classifier`\n    * doing a forward pass on just the features - `forward_features` (see [documentation](https://huggingface.co/docs/timm/feature_extraction))\n    * these makes it easy to write consistent network wrappers that work with any of the models\n* All models support multi-scale feature map extraction (feature pyramids) via create_model (see [documentation](https://huggingface.co/docs/timm/feature_extraction))\n    * `create_model(name, features_only=True, out_indices=..., output_stride=...)`\n    * `out_indices` creation arg specifies which feature maps to return, these indices are 0 based and generally correspond to the `C(i + 1)` feature level.\n    * `output_stride` creation arg controls output stride of the network by using dilated convolutions. Most networks are stride 32 by default. Not all networks support this.\n    * feature map channel counts, reduction level (stride) can be queried AFTER model creation via the `.feature_info` member\n* All models have a consistent pretrained weight loader that adapts last linear if necessary, and from 3 to 1 channel input if desired\n* High performance [reference training, validation, and inference scripts](https://huggingface.co/docs/timm/training_script) that work in several process/GPU modes:\n    * NVIDIA DDP w/ a single GPU per process, multiple processes with APEX present (AMP mixed-precision optional)\n    * PyTorch DistributedDataParallel w/ multi-gpu, single process (AMP disabled as it crashes when enabled)\n    * PyTorch w/ single GPU single process (AMP optional)\n* A dynamic global pool implementation that allows selecting from average pooling, max pooling, average + max, or concat([average, max]) at model creation. All global pooling is adaptive average by default and compatible with pretrained weights.\n* A 'Test Time Pool' wrapper that can wrap any of the included models and usually provides improved performance doing inference with input images larger than the training size. Idea adapted from original DPN implementation when I ported (https://github.com/cypw/DPNs)\n* Learning rate schedulers\n  * Ideas adopted from\n     * [AllenNLP schedulers](https://github.com/allenai/allennlp/tree/master/allennlp/training/learning_rate_schedulers)\n     * [FAIRseq lr_scheduler](https://github.com/pytorch/fairseq/tree/master/fairseq/optim/lr_scheduler)\n     * SGDR: Stochastic Gradient Descent with Warm Restarts (https://arxiv.org/abs/1608.03983)\n  * Schedulers include `step`, `cosine` w/ restarts, `tanh` w/ restarts, `plateau`\n* Optimizers:\n    * `rmsprop_tf` adapted from PyTorch RMSProp by myself. Reproduces much improved Tensorflow RMSProp behaviour.\n    * `radam` by [Liyuan Liu](https://github.com/LiyuanLucasLiu/RAdam) (https://arxiv.org/abs/1908.03265)\n    * `novograd` by [Masashi Kimura](https://github.com/convergence-lab/novograd) (https://arxiv.org/abs/1905.11286)\n    * `lookahead` adapted from impl by [Liam](https://github.com/alphadl/lookahead.pytorch) (https://arxiv.org/abs/1907.08610)\n    * `fused<name>` optimizers by name with [NVIDIA Apex](https://github.com/NVIDIA/apex/tree/master/apex/optimizers) installed\n    * `adamp` and `sgdp` by [Naver ClovAI](https://github.com/clovaai) (https://arxiv.org/abs/2006.08217)\n    * `adafactor` adapted from [FAIRSeq impl](https://github.com/pytorch/fairseq/blob/master/fairseq/optim/adafactor.py) (https://arxiv.org/abs/1804.04235)\n    * `adahessian` by [David Samuel](https://github.com/davda54/ada-hessian) (https://arxiv.org/abs/2006.00719)\n* Random Erasing from [Zhun Zhong](https://github.com/zhunzhong07/Random-Erasing/blob/master/transforms.py)  (https://arxiv.org/abs/1708.04896)\n* Mixup (https://arxiv.org/abs/1710.09412)\n* CutMix (https://arxiv.org/abs/1905.04899)\n* AutoAugment (https://arxiv.org/abs/1805.09501) and RandAugment (https://arxiv.org/abs/1909.13719) ImageNet configurations modeled after impl for EfficientNet training (https://github.com/tensorflow/tpu/blob/master/models/official/efficientnet/autoaugment.py)\n* AugMix w/ JSD loss (https://arxiv.org/abs/1912.02781), JSD w/ clean + augmented mixing support works with AutoAugment and RandAugment as well\n* SplitBachNorm - allows splitting batch norm layers between clean and augmented (auxiliary batch norm) data\n* DropPath aka \"Stochastic Depth\" (https://arxiv.org/abs/1603.09382)\n* DropBlock (https://arxiv.org/abs/1810.12890)\n* Blur Pooling (https://arxiv.org/abs/1904.11486)\n* Space-to-Depth by [mrT23](https://github.com/mrT23/TResNet/blob/master/src/models/tresnet/layers/space_to_depth.py) (https://arxiv.org/abs/1801.04590) -- original paper?\n* Adaptive Gradient Clipping (https://arxiv.org/abs/2102.06171, https://github.com/deepmind/deepmind-research/tree/master/nfnets)\n* An extensive selection of channel and/or spatial attention modules:\n    * Bottleneck Transformer - https://arxiv.org/abs/2101.11605\n    * CBAM - https://arxiv.org/abs/1807.06521\n    * Effective Squeeze-Excitation (ESE) - https://arxiv.org/abs/1911.06667\n    * Efficient Channel Attention (ECA) - https://arxiv.org/abs/1910.03151\n    * Gather-Excite (GE) - https://arxiv.org/abs/1810.12348\n    * Global Context (GC) - https://arxiv.org/abs/1904.11492\n    * Halo - https://arxiv.org/abs/2103.12731\n    * Involution - https://arxiv.org/abs/2103.06255\n    * Lambda Layer - https://arxiv.org/abs/2102.08602\n    * Non-Local (NL) -  https://arxiv.org/abs/1711.07971\n    * Squeeze-and-Excitation (SE) - https://arxiv.org/abs/1709.01507\n    * Selective Kernel (SK) - (https://arxiv.org/abs/1903.06586\n    * Split (SPLAT) - https://arxiv.org/abs/2004.08955\n    * Shifted Window (SWIN) - https://arxiv.org/abs/2103.14030\n\n## Results\n\nModel validation results can be found in the [results tables](results/README.md)\n\n## Getting Started (Documentation)\n\nThe official documentation can be found at https://huggingface.co/docs/hub/timm. Documentation contributions are welcome.\n\n[Getting Started with PyTorch Image Models (timm): A Practitioner\u2019s Guide](https://towardsdatascience.com/getting-started-with-pytorch-image-models-timm-a-practitioners-guide-4e77b4bf9055) by [Chris Hughes](https://github.com/Chris-hughes10) is an extensive blog post covering many aspects of `timm` in detail.\n\n[timmdocs](http://timm.fast.ai/) is an alternate set of documentation for `timm`. A big thanks to [Aman Arora](https://github.com/amaarora) for his efforts creating timmdocs.\n\n[paperswithcode](https://paperswithcode.com/lib/timm) is a good resource for browsing the models within `timm`.\n\n## Train, Validation, Inference Scripts\n\nThe root folder of the repository contains reference train, validation, and inference scripts that work with the included models and other features of this repository. They are adaptable for other datasets and use cases with a little hacking. See [documentation](https://huggingface.co/docs/timm/training_script).\n\n## Awesome PyTorch Resources\n\nOne of the greatest assets of PyTorch is the community and their contributions. A few of my favourite resources that pair well with the models and components here are listed below.\n\n### Object Detection, Instance and Semantic Segmentation\n* Detectron2 - https://github.com/facebookresearch/detectron2\n* Segmentation Models (Semantic) - https://github.com/qubvel/segmentation_models.pytorch\n* EfficientDet (Obj Det, Semantic soon) - https://github.com/rwightman/efficientdet-pytorch\n\n### Computer Vision / Image Augmentation\n* Albumentations - https://github.com/albumentations-team/albumentations\n* Kornia - https://github.com/kornia/kornia\n\n### Knowledge Distillation\n* RepDistiller - https://github.com/HobbitLong/RepDistiller\n* torchdistill - https://github.com/yoshitomo-matsubara/torchdistill\n\n### Metric Learning\n* PyTorch Metric Learning - https://github.com/KevinMusgrave/pytorch-metric-learning\n\n### Training / Frameworks\n* fastai - https://github.com/fastai/fastai\n\n## Licenses\n\n### Code\nThe code here is licensed Apache 2.0. I've taken care to make sure any third party code included or adapted has compatible (permissive) licenses such as MIT, BSD, etc. I've made an effort to avoid any GPL / LGPL conflicts. That said, it is your responsibility to ensure you comply with licenses here and conditions of any dependent licenses. Where applicable, I've linked the sources/references for various components in docstrings. If you think I've missed anything please create an issue.\n\n### Pretrained Weights\nSo far all of the pretrained weights available here are pretrained on ImageNet with a select few that have some additional pretraining (see extra note below). ImageNet was released for non-commercial research purposes only (https://image-net.org/download). It's not clear what the implications of that are for the use of pretrained weights from that dataset. Any models I have trained with ImageNet are done for research purposes and one should assume that the original dataset license applies to the weights. It's best to seek legal advice if you intend to use the pretrained weights in a commercial product.\n\n#### Pretrained on more than ImageNet\nSeveral weights included or references here were pretrained with proprietary datasets that I do not have access to. These include the Facebook WSL, SSL, SWSL ResNe(Xt) and the Google Noisy Student EfficientNet models. The Facebook models have an explicit non-commercial license (CC-BY-NC 4.0, https://github.com/facebookresearch/semi-supervised-ImageNet1K-models, https://github.com/facebookresearch/WSL-Images). The Google models do not appear to have any restriction beyond the Apache 2.0 license (and ImageNet concerns). In either case, you should contact Facebook or Google with any questions.\n\n## Citing\n\n### BibTeX\n\n```bibtex\n@misc{rw2019timm,\n  author = {Ross Wightman},\n  title = {PyTorch Image Models},\n  year = {2019},\n  publisher = {GitHub},\n  journal = {GitHub repository},\n  doi = {10.5281/zenodo.4414861},\n  howpublished = {\\url{https://github.com/rwightman/pytorch-image-models}}\n}\n```\n\n### Latest DOI\n\n[![DOI](https://zenodo.org/badge/168799526.svg)](https://zenodo.org/badge/latestdoi/168799526)\n",
