Hi Soumith,
I download “cifar10_tutorial.py"from http://pytorch.org/tutorials/beginner/blitz/cifar10_tutorial.html 79.
When I run this file in Spyder on Windows10, it reports"BrokenPipeError: [Errno 32] Broken pipe”, the details information are as follows:

runfile(‘D:/PyTorch/Code/LearnPyTorch/cifar10_tutorial.py’, wdir=‘D:/PyTorch/Code/LearnPyTorch’)

Could you give me any advise to help me run “cifar10_tutorial.py” successfully? By the way, other examples in “Deep Learning with PyTorch: A 60 Minute Blitz” have been run suceessfully.
