The torchscript weight from YoLoV5 is not workable

[Jelly123456]

Thanks very much for creating this repo.

Now I am facing one problem that the converted torchscript weight from YoLoV5 is not working with the code you provided.

The conversion is followed on this: https://github.com/ultralytics/yolov5/issues/251

The image size is set to [640, 640] and I also modified your code to be 640.

When loading your existing torchscript weight, it works perfectly.

Do you know which could be the reasons?

Thanks.

I solved this by changing some codes in the export.py from YoLoV5 repo.

It may be that the author of YOLOv5 updated the repo so that some operators in the network are not supported. Perhaps you can solve this problem by cloning the previous version of the YOLOv5 repo and use "export.py" to get the torchscript file.

Thanks very much for your reply. Now I could not run with the torchscript model exported in GPU mode. Do you know how to solve it?

Export the torchscript with map_location=torch.device('cuda') will do

@1chimaruGin @yy2lyx You can follow the instructions in this repo. I tried successfully with GPU + Linux environment.
