About opencv-python-cuda

This project provides pre-built NVIDIA® CUDA™ enabled OpenCV packages for Python that come with all batteries included. It is a fork of the official opencv-python project. Currently, packages are only produced for Windows x64, and devices must be Maxwell class (GeForce 900 series) or newer.

The wheel is fully standalone — no CUDA Toolkit, cuDNN, or any other NVIDIA software needs to be installed on your system. All required runtime libraries are bundled directly in the package. Just install the .whl file and you're ready to go.

Once installed via pip (or another Python package manager like uv), the following should just work:

import cv2
print(cv2.cuda.getCudaEnabledDeviceCount())
