Running PENCIL codes

[varvanih]

Hello,

I am new to Python and neural networks. I am trying to run this code and comparing the results with the reference paper. I encountered some errors and solved them. But now I encountered an error and have now idea about that:

BrokenPipeError: [Errno 32] Broken pipe

I have some questions and I appreciate it if you could help me:

1 - What is the reason for this error?
2 - Can this code run without any GPU?
3 - Is there any help or guide on how to use and run the codes available here for beginners?

Thanks
Hossein
