Hi, I saw that the precompiled binaries dropped support for my (older) GPU and read that I need to compile from source. I’m relatively new to installing large projects from source and I’ve hit a roadblock. After installing cuda and cudnn and following the provided instructions found on pytorch.org 6 I’m failing the build process with the following output. Any help would be very much appreciated.
