cupy is not correctly installed. if you are using wheel distribution (cupy-cudaxx), make sure that the version of cupy you installed matches with the version of cuda on your host. also, confirm that only one cupy package is installed: $ pip freeze if you are building cupy from source, please check your environment, uninstall cupy and reinstall it with: $ pip install cupy --no-cache-dir -vvvv

이 문제에 대해서는 anaconda에 cupy를 따로 설치해야 할 것이라 판단하여

$ conda install -c conda-forge cupy
