I tried using a method similar to the one in DeepLabCut 2.x, but the network didn't work. After reviewing the explanation document for the pytorch_config.yaml file (https://deeplabcut.github.io/DeepLabCut/docs/pytorch/pytorch_config.html#dlc3-pytorch-config), I still couldn't find any relevant information on this feature. Does this operation not yet have support in the current version?
