What’s weightspath? How was the model saved? If it was saved as a state_dict(), you may need to reconstruct the class that generated the model first before loading it.

Thanks for your reply.
yes, it is saved as a state_dict,
weights_dict = torch.load(weightspath) simply loads it as a dictionary.

It seems to me that if the model is trained using GPU #3 on another machine, the saved model can not be loaded by a different machine with only 2 gpus.
