I encountered this problem first.
>>> from setuptools import setup, Extension
>>> from torch.utils import cpp_extension
INFO: Could not find files for the given pattern(s).

And when I’m trying to use code here 24 to compile a simple extension, I encountered this issue, which I suspect is related to the problem above. But I’m not sure what is it exactly.
UserWarning: Error checking compiler version for cl: [WinError 2] The system cannot find the file specified

I googled this issue but didn’t find a satisfactory answer.
