Model card for tresnet_l.miil_in1k#
A TResNet image classification model. Trained on ImageNet-1k by paper authors.
The weights for this model have been remapped and modified from the originals to work with standard BatchNorm instead of InplaceABN. inplace_abn can be problematic to build recently and ends up slower with memory_format=channels_last, torch.compile(), etc.
