What version of CUDA did you install? Also what GPU do you have? CUDA is failing on an old sm_20 architecture (Fermi, which is an old GPU model). You could try following these instructions in the CMakeLists.txt file (https://stackoverflow.com/questions/47663033/nvcc-fatal-value-sm-20-is-not-defined-for-option-gpu-architecture).

Thank you for your reply. My CUDA version is 10.1 and GPU is titanX(pascal)

jacobaustin123 commented 3 years ago

So this seems like an issue with the CUDA installation itself. Are you able to run nvcc from the command line? Or install other gpu based software like pytorch/tensorflow?

There may be a simple fix on my end, but let me know about other programs.
