I retrained my model again, but after exporting to torchscript, I got the same error. Does anyone encounter the same problem?

@Andy824 thanks for the bug report! We recently updated this section of the code, I'll take a look.

@Andy824 I'm not able to reproduce any errors using the pretrained YOLOv5s model exported to torchscript. Are you sure you are using the latest code?

[glenn-jocher]

@Andy824 EDIT: able to reproduce on custom trained model. Will investigate.

Traced to JSON dumps converting int keys to strings during export, i.e.
