The error message ModuleNotFoundError: No module named ‘cupy’ is a common error that occurs in Python when the interpreter can’t locate the ‘cupy’ module.
This can happen due to a few reasons:
- The cupy module might not be installed in your Python environment.
- If you have multiple Python environments, you might be using an environment where cupy isn’t installed.
- You might be trying to import a part of the module that doesn’t exist.
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
If you’re using a specific CUDA version, you’ll need to install the corresponding cupy-cudaXX package.
Step 2: Check your Python environment
Ensure that you’re using the Python environment where cupy is installed.
Step 3: Correct your import statements
Make sure you’re importing the correct submodules or functions from cupy.
Step 4: Reinstalling
If you’ve tried these steps and are still seeing the error, it might help to uninstall and reinstall cupy.

pip uninstall cupyTo reinstall, use the following command:
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.
