4.13.0-dev1
f2c1edd

Preview build of OpenCV 4.13.0 with CUDA support, including hardware video encode/decode (NVDEC/NVENC).

Installation

pip install opencv_python_cuda-4.13.0+f2c1edd-cp37-abi3-win_amd64.whl

Make sure to uninstall any existing OpenCV packages first. This package can be uninstalled via pip uninstall opencv-python-cuda.

Build/Version Information

  • Build Run
  • OpenCV 4.13.0 with all features excluding non-free
  • Nvidia CUDA Toolkit v12.9.1
  • Nvidia CuDNN 9.18.1.3
  • Nvidia Video Codec SDK 13.0.37 (hardware video decode/encode)
  • Device compatibility: Maxwell through Blackwell (SASS: 5.0, 5.2, 6.0, 6.1, 7.0, 7.5, 8.0, 8.6, 8.9, 9.0, 10.0; PTX: 10.0)

System Requirements

  • Windows 7 64-bit or newer
  • Python 3.7 or newer
  • Nvidia GPU that is Maxwell-class or newer (GeForce 900-series)
  • Nvidia display driver must be installed: cv2 links against nvcuvid.dll / nvEncodeAPI64.dll, which ship with the driver, so import cv2 fails on machines without it

Changes from 4.12.0-dev2

  • Updated OpenCV from 4.12.0 to 4.13.0 (merged upstream opencv-python 4.x, including packaging updates)
  • CI build runners pinned to windows-2022 (windows-2025 dropped the VS2022 toolset required by CUDA 12.x)
