PyTorch Image Models

Sponsors

Thanks to the following for hardware support:

And a big thanks to all GitHub sponsors who helped with some of my costs before I joined Hugging Face.

What's New

  • ❗Updates after Oct 10, 2022 are available in 0.8.x pre-releases (pip install --pre timm) or cloning main❗
  • Stable releases are 0.6.x and available by normal pip install or clone from 0.6.x branch.

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
    • rexnetr_300.sw_in12k_ft_in1k - 84.0 @ 224, 84.5 @ 288
    • regnety_120.sw_in12k_ft_in1k - 85.0 @ 224, 85.4 @ 288
    • regnety_160.lion_in12k_ft_in1k - 85.6 @ 224, 86.0 @ 288
    • regnety_160.sw_in12k_ft_in1k - 85.6 @ 224, 86.0 @ 288 (compare to SWAG PT + 1k FT this is same BUT much lower res, blows SEER FT away)
  • Model name deprecation + remapping functionality added (a milestone for bringing 0.8.x out of pre-release). Mappings being added...
  • Minor bug fixes and improvements.

Feb 26, 2023

  • Add ConvNeXt-XXLarge CLIP pretrained image tower weights for fine-tune & features (fine-tuning TBD) -- see model card
  • Update convnext_xxlarge default LayerNorm eps to 1e-5 (for CLIP weights, improved stability)
  • 0.8.15dev0

Feb 20, 2023

  • Add 320x320 convnext_large_mlp.clip_laion2b_ft_320 and convnext_lage_mlp.clip_laion2b_ft_soup_320 CLIP image tower weights for features & fine-tune
  • 0.8.13dev0 pypi release for latest changes w/ move to huggingface org

Feb 16, 2023

  • safetensor checkpoint support added
  • Add ideas from 'Scaling Vision Transformers to 22 B. Params' (https://arxiv.org/abs/2302.05442) -- qk norm, RmsNorm, parallel block
  • Add F.scaled_dot_product_attention support (PyTorch 2.0 only) to vit_*, vit_relpos*, coatnet / maxxvit (to start)
  • Lion optimizer (w/ multi-tensor option) added (https://arxiv.org/abs/2302.06675)
  • gradient checkpointing works with features_only=True

Feb 7, 2023

  • New inference benchmark numbers added in results folder.
  • Add convnext LAION CLIP trained weights and initial set of in1k fine-tunes
    • convnext_base.clip_laion2b_augreg_ft_in1k - 86.2% @ 256x256
    • convnext_base.clip_laiona_augreg_ft_in1k_384 - 86.5% @ 384x384
    • convnext_large_mlp.clip_laion2b_augreg_ft_in1k - 87.3% @ 256x256
    • convnext_large_mlp.clip_laion2b_augreg_ft_in1k_384 - 87.9% @ 384x384
  • Add DaViT models. Supports features_only=True. Adapted from https://github.com/dingmyu/davit by Fredo.
  • Use a common NormMlpClassifierHead across MaxViT, ConvNeXt, DaViT
  • Add EfficientFormer-V2 model, update EfficientFormer, and refactor LeViT (closely related architectures). Weights on HF hub.

    • Update inference.py to use, try: python inference.py /folder/to/images --model convnext_small.in12k --label-type detail --topk 5
  • Ready for 0.8.10 pypi pre-release (final testing).

Jan 20, 2023

  • Add two convnext 12k -> 1k fine-tunes at 384x384

    • convnext_tiny.in12k_ft_in1k_384 - 85.1 @ 384

  • 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
  • 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

    • Small ResNet defs added by request with 1 block repeats for both basic and bottleneck (resnet10 and resnet14)
    • CspNet refactored with dataclass config, simplified CrossStage3 (cs3) option. These are closer to YOLO-v5+ backbone defs.
    • More relative position vit fiddling. Two srelpos (shared relative position) models trained, and a medium w/ class token.
    • Add an alternate downsample mode to EdgeNeXt and train a small model. Better than original small, but not their new USI trained weights.

  • Add support to change image extensions scanned by timm datasets/readers. See (https://github.com/rwightman/pytorch-image-models/pull/1274#issuecomment-1178303103)
  • Default ConvNeXt LayerNorm impl to use F.layer_norm(x.permute(0, 2, 3, 1), ...).permute(0, 3, 1, 2) via LayerNorm2d in all cases.

    • previous impl exists as LayerNormExp2d in models/layers/norm.py
  • Numerous bug fixes
  • Currently testing for imminent PyPi 0.6.x release
  • LeViT pretraining of larger models still a WIP, they don't train well / easily without distillation. Time to add distill support (finally)?

Feb 2, 2022

  • Chris Hughes posted an exhaustive run through of timm on his blog yesterday. Well worth a read. Getting Started with PyTorch Image Models (timm): A Practitioner’s Guide
  • I'm currently prepping to merge the norm_norm_norm branch back to master (ver 0.6.x) in next week or so.
    • The changes are more extensive than usual and may destabilize and break some model API use (aiming for full backwards compat). So, beware pip install git+https://github.com/rwightman/pytorch-image-models installs!
    • 0.5.x releases and a 0.5.x branch will remain stable with a cherry pick or two until dust clears. Recommend sticking to pypi install for a bit if you want stable.

Jan 14, 2022

  • Version 0.5.4 w/ release to be pushed to pypi. It's been a while since last pypi update and riskier changes will be merged to main branch soon....
  • Add ConvNeXT models /w weights from official impl (https://github.com/facebookresearch/ConvNeXt), a few perf tweaks, compatible with timm features
  • Tried training a few small (~1.8-3M param) / mobile optimized models, a few are good so far, more on the way...
    • mnasnet_small - 65.6 top-1
    • mobilenetv2_050 - 65.9
    • lcnet_100/075/050 - 72.1 / 68.8 / 63.1

Introduction

PyTorch Image Models (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:

Results

Model validation results can be found in the results tables

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 by Chris Hughes is an extensive blog post covering many aspects of timm in detail.

timmdocs is an alternate set of documentation for timm. A big thanks to Aman Arora for his efforts creating timmdocs.

paperswithcode 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.

Awesome PyTorch Resources

One 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.

Object Detection, Instance and Semantic Segmentation

Computer Vision / Image Augmentation

Knowledge Distillation

Metric Learning

Training / Frameworks

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.
