Hey guys,
I’m trying to contribute to the pytorch repo and therefore I need to install pytorch from souce with the develop flag.
I followed the OSX specific instructions here 9 and here 8.
The code compiles, but it generates a bunch of warnings and in the end I am not able to run the unit tests code.
Running test_autograd.py ...
