Hi @trianoncentury,

compute capability sm_30 (which is a constant set in CMakeLists.txt) is supported up to CUDA 10.2, you have 12.0.

To know the compute caps of your GPU:

nvidia-smi --query-gpu=compute_cap --format=csv

If your card supports caps newer than sm_30 then change CMakeLists.txt accordingly, otherwise you have to downgrade CUDA.
