  • Support loading PaliGemma jax weights into SigLIP ViT models with average pooling.
  • Add Hiera models from Meta (https://github.com/facebookresearch/hiera).
  • Add normalize= flag for transorms, return non-normalized torch.Tensor with original dytpe (for chug)
  • Version 1.0.3 release

May 11, 2024

  • Searching for Better ViT Baselines (For the GPU Poor) weights and vit variants released. Exploring model shapes between Tiny and Base.

  • AttentionExtract helper added to extract attention maps from timm models. See example in #1232 (comment)
  • forward_intermediates() API refined and added to more models including some ConvNets that have other extraction methods.
  • 1017 of 1047 model architectures support features_only=True feature extraction. Remaining 34 architectures can be supported but based on priority requests.
  • Remove torch.jit.script annotated functions including old JIT activations. Conflict with dynamo and dynamo does a much better job when used.

  • Prepping for a long overdue 1.0 release, things have been stable for a while now.
  • Significant feature that's been missing for a while, features_only=True support for ViT models with flat hidden states or non-std module layouts (so far covering 'vit_*', 'twins_*', 'deit*', 'beit*', 'mvitv2*', 'eva*', 'samvit_*', 'flexivit*')
  • Above feature support achieved through a new forward_intermediates() API that can be used with a feature wrapping module or direclty.
model = timm.create_model('vit_base_patch16_224')
final_feat, intermediates = model.forward_intermediates(input) 
output = model.forward_head(final_feat)  # pooling + classifier head

print(final_feat.shape)
torch.Size([2, 197, 768])

for f in intermediates:
    print(f.shape)
torch.Size([2, 768, 14, 14])

output = model(torch.randn(2, 3, 512, 512))

  • TinyCLIP vision tower weights added, thx Thien Tran
