The commands I used are:
conda create --name p37_build python=3.7
conda activate p37_build
conda install numpy pyyaml mkl mkl-include setuptools cmake cffi typing
git clone --recursive https://github.com/pytorch/pytorch 2
export CMAKE_PREFIX_PATH=${CONDA_PREFIX:-"$(dirname $(which conda))/…/"}
export USE_CUDA=1 USE_CUDNN=1 USE_MKLDNN=1
cd pytorch/
python setup.py install 2>&1 > build.log
