How to fix the modulenotfounderror: no module named cupy?

To resolve this, you can try the following steps:

Step 1: Install CuPy

Use pip to install the cupy module.

pip install cupy --no-cache-dir

The –no-cache-dir option ensures that cupy is rebuilt from source.

If necessary, please replace pip with pip3 or the equivalent command for your Python 3 environment.

If you’re using a specific version of CUDA, replace cupy with cupy-cudaXX where XX is your CUDA version.

For example, if you’re using CUDA 10.0, you would use cupy-cuda100.
