Disclaimer: I am new to source builds of pytorch.
I was able to build and install pytorch successfully, following https://pytorch.org/get-started/locally/#windows-from-source against a miniconda environment. Two questions remain for me:
-
torchvision: Is this part of the package? I couldn’t found any egg/whl. Any knobs, I am not aware yet?
-
Out-of-Source builds gives me the following error:

I am not very well-versed in python’s setup.py framework, so it is easily possible that I make very simple errors here. My call to setup.py comes from my intended build directory for cmake and has the form:
python ..\src\pytorch\setup.py install
Are there any options, providing setup.py with the correct build directory in order to transfer this information to cmake? (The mentioned caffe2/proto/caffe2_legacy_pb2.py was copied to this build directory - but the leading path seems to be missing).
Unrelated: Would a ‘build’ category possible for this forum (similar to ‘deployment’)?
