Hi Soumith,
I checked some parts of the builder script. https://github.com/pytorch/builder/blob/master/conda/switch_cuda_version.sh 92
Although I haven’t tested it, it seems that, the CUDA and cuDNN is not handled by conda, and instead they are installed in system-level directories.
Seems that I should get myself an environment like that in https://github.com/pytorch/builder/tree/master/manywheel 76, and then run scripts under wheel?
