When exporting PYTORCH_BUILD_VERSION=1.10.0 and PYTORCH_BUILD_NUMBER=1, I could build locally version 1.10.0 with PyTorch 1.10.0-rc3 from source. However, the cuda113 torchvision rc requests PyTorch version 1.10.0+cu113, and the PyTorch build fails if I export PYTORCH_BUILD_VERSION=1.10.0+cu113. I looked into the python script, and yet could only find this one method to specify the PyTorch version. I wondering how PyTorch team built the wheel with the cuda version tag. Similarly for CPU binaries, how did the public binary come with 1.10.0+cpu? Could someone help here? Thanks!
