Answer 1

Pytorch or torch is currently cannot be installed using pypi in windows. You will need conda to accomplish that:

conda install pytorch torchvision cudatoolkit=9.0 -c pytorch

OR

for older torch version you can use whl file, Cuda version can be 8.0,9.0,10.0

pip install torch==1.0.1 -f https://download.pytorch.org/whl/cu90/stable # CUDA 9.0 build
