Recent Changes
Aug 28, 2023
- Add dynamic img size support to models in
vision_transformer.py
,vision_transformer_hybrid.py
,deit.py
, andeva.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

weights above all trained on TPU thanks to TRC program! Rest trained on overheating GPUs.- Hugging Face Hub support fixes verified, demo notebook TBA
- Pretrained weights / configs can be loaded externally (ie from local disk) w/ support for head adaptation.
- 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

in all cases.- a bit slower than previous custom impl on some hardware (ie Ampere w/ CL), but overall fewer regressions across wider HW / PyTorch version ranges.
- previous impl exists as

inmodels/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)?
- ImageNet-22k weight training + finetune ongoing, work on multi-weight support (slowly) chugging along (there are a LOT of weights, sigh) …

- 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 a0.5.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.

weights above all trained on TPU thanks to TRC program! Rest trained on overheating GPUs.- Hugging Face Hub support fixes verified, demo notebook TBA
- Pretrained weights / configs can be loaded externally (ie from local disk) w/ support for head adaptation.
- Add support to change image extensions scanned by
timm
datasets/parsers. 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)
viaLayerNorm2d
in all cases.- a bit slower than previous custom impl on some hardware (ie Ampere w/ CL), but overall fewer regressions across wider HW / PyTorch version ranges.
- previous impl exists as
LayerNormExp2d
inmodels/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)?
- ImageNet-22k weight training + finetune ongoing, work on multi-weight support (slowly) chugging along (there are a LOT of weights, sigh) …

- Official Swin-V2 models and weights added from (https://github.com/microsoft/Swin-Transformer). Cleaned up to support torchscript.
- Some refactoring for existing
timm
Swin-V2-CR impl, will likely do a bit more to bring parts closer to official and decide whether to merge some aspects. - More Vision Transformer relative position / residual post-norm experiments (all trained on TPU thanks to TRC program)

How to Train Your ViT
) vit_*
models support removal of class token, use of global average pool, use of fc_norm (ala beit, mae).

. IMPORTANT this update for a coming 0.6.x release will likely de-stabilize the master branch for a while. Branch0.5.x
or a previous 0.5.x release can be used if stability is required. - Significant weights update (all TPU trained) as described in this release

- 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 a0.5.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.

- 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…
