build error

[waky80]

I tried building Nimble. I had the following error. Can you help me?

Than you.

Thanks for you interest! I think this error is not relevant to the changes (for Nimble) we've made in PyTorch's codebase. In fact, the log that you've attached above has no information about which part of the code made the compilation unsuccessful. Can you first "clean" your build history (simply run python setup.py clean) and then retry the build again?

If you still have problem after cleaning the history, I think you should first try building PyTorch v1.4.1 because I expect you will have the same problem in building the original PyTorch codebase.
