Must compile on GPU session.

compile with CUDA support install Ubuntu's default CUDA package:

!sudo apt-get install -y
nvidia-cuda-toolkit
nvidia-cuda-toolkit-gcc

In the CMakeFile.txt, I add these lines: set(CMAKE_CUDA_COMPILER "/usr/local/cuda/bin/nvcc") set(CMAKE_CUDA_ARCHITECTURES 52 60 61 75 86) Upgrade cmake to version 3.26.1 cmake .. -GNinja ninja sudo ninja install
