@glenn best practices for running trained YOLOv5 models in new python environments is to use PyTorch Hub. See PyTorch Hub Tutorial:

@Glenn but when I use "torch.hub.load" to load my own model weights, it raises an error "RuntimeError: Cannot find callable custom in hubconf"

[glenn-jocher]

@BruceYangxl your cache is out of date (you are using old code). use force_reload=True as shown in PyTorch Hub tutorial:
https://docs.ultralytics.com/yolov5

Force Reload

If you run into problems with the above steps, setting force_reload=True may help by discarding the existing cache and force a fresh download of the latest YOLOv5 version from PyTorch Hub.

model = torch.hub.load('ultralytics/yolov5', 'yolov5s', pretrained=True, force_reload=True)  # force reload
