I am brand-new to PyTorch and trying to get up to speed. I installed PyTorch on a 64 bit virtual machine running CentOS 7.5. Host processor is AMD 4 core Phenom IIx4 945.
Python 3.6.8
Gcc 4.8.5 20150603
No GPU
Installation instruction (from website)
pip3 install torch==1.3.1+cpu torchvision==0.4.2+cpu -f https://download.pytorch.org/whl/torch_stable.html 6
In the third section of the “60 minute blitz tutorial”, following all the instructions, I entered:
out.backward(torch.randn(1, 10))
And got a core dump.



out.backward(torch.randn(1,10))
Illegal instruction (core dumped)



Having the tutorial crash looks really bad ;^)  Also interfering with my goal to learn PyTorch!
I’d appreciate help with this. Thanks.
