Hi.
I have got a question. I have trained a deep neural network on GPU, and then finally moved my GPU mode  deep network to the CPU mode. Further more, after saving CPU mode network with  torch.save(net.state_dict(), 'final.pth') and moving to another system and loading with net.load_state_dict(torch.load('./final.pth')) and running it, I have encountered with below error. Could you please help me what is the problem of my code?

Traceback (most recent call last):

n = int(s.strip() or “0”, 8)

I have to say that my server’s pytorch version is 0.1.11 and my own system is 0.1.8. Is this the source of error?
Thanks
Edit 1:
I have tried above code on our server. It is actually fine and without error. These errors were started to generate when I reinstalled pytorch.
Edit 2:
The saved format before reinstallation of pytorch on our server was .tar but after reinstallation it has changed to Binary. Moreover, I should say that all of the conversion are done on server!
