remove dependency on timm/resnet18.a1_in1k when using Padim()

[lilz-egoto]

Hi, I have something that uses anomalib.models.Padim() and I have noticed that everytime that it is called, it downloads a model from an external source https://huggingface.co:443 "HEAD /timm/resnet18.a1_in1k/resolve/main/model.safetensors HTTP/11" 302 0. Is it possible to just have this downloaded locally and have the library refer to the local file? I have combed through documentation and tried fiddling with the class and methods, but there doesn't seem to be a way to do this.

@lilz-egoto I feel that'd be on the anomalib Padmin to allow disabling timm pretrained load when it's not needed, is there not a flag?

timm weights usually check the HF hub if pretrained is enable to ensure up to date weights being used (even if DL not needed). Can run with HF_HUB_OFFLINE=1 in env to disable the check and use whatever is currently in cache (does need something in cache though).

Oh woops, I thought this was anomalib, I'll make a post there
