Missing numpy dependency at installation #2188
Description
I installed PyTorch on a fresh Python 3.6 installation (brew install python3), got an error and found out that numpy wasn't installed. I installed numpy and then things work. Shouldn't it be included among dependencies of the PyTorch package?
