Cupy cuda error.

Hello,
I could not make it work with different combinations of cupy's and cudatoolkits. I have cuda 11.5. Should I install an older version of cuda? What are the dependencies?
Original error:
ImportError: libnvrtc.so.11.1: cannot open shared object file: No such file or directory
another error,
Original error:
ImportError: /home/istek/.local/lib/python3.8/site-packages/cupy_backends/cuda/api/runtime.cpython-38-x86_64-linux-gnu.so: undefined symbol: cudaMallocAsync
and some other cuda errors for different versions.
You need to make sure that PyTorch uses the same CUDA toolkit version as CuPy as well as your system. You can check the CUDA version installed on your system with nvcc --version, for PyTorch you can do print(torch.version.cuda) and for CuPy you can do cupy.show_config().
