not sure you are still having this error but in case you are having, run nvidia-smi you should see which cuda version you have in here NVIDIA-SMI 435.21 Driver Version: 435.21 CUDA Version: 10.1 for me it's 10.1 after learning the cuda version go to cupy installation page here

and install the correct cupy with same cuda version for me it's pip install cupy-cuda101

this should work, in case it's not working comment here.

@hikmet-demir Wow, it's been a while... But I'll try to do something.

My cuda version is NVIDIA-SMI 450.119.03 Driver Version: 450.119.03 CUDA Version: 11.0 I followed the steps suggested by @hikmet-demir but I got this error - "ImportError: CuPy is not installed correctly." However, pip install cupy --no-cache-dir -vvvv worked for me.
