cfinlay / pytorch-helloworld Goto Github PK

I was trying to implement and run the code. Everything seems to be fine unless I met the following two errors when running the code.

I am new to deep learning & PyTorch. I googled the issue and practiced the solution on StackOverFlow . I don't understand the problem or the solution much but it works.

My environment: Nvidia Tesla P4, cuda 10.0.130, cudnn 7.4.2, pytorch 1.0.1.

Hope it helps.
