v0.9.6

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
