Hello Guys, I did all the processes to compile OpenCV 4.5 with CUDA processor support. as in the image below

But when I check which version is in python3 OpenCV presents the previous version 3.2.0

I already tried to update Python3-OpenCV, already recompile OpenCV 4.5. And it remains the same.

Do you have any idea what I can do ???

Best Regards

Hi,
For more information, do you run this script to build/install OpenCV4.5.0?
JEP/install_opencv4.5.0_Jetson.sh at master · AastaNV/JEP · GitHub

Thank you Danell.

Python3-opencv4.5.0 has been updated

This step is much better than the ones I followed to update opencv4.5.

BTW, NVIDIA L4T ML | NVIDIA NGC this docker image is a better and easy way to test OpenCV4.5 TF Pytorch and basic platform you want.

  • JetPack 4.6 (L4T R32.6.1)
    • l4t-ml:r32.6.1-py3
      • TensorFlow 1.15.5
      • PyTorch v1.9.0
      • torchvision v0.10.0
      • torchaudio v0.9.0
      • onnx 1.8.0
      • CuPy 9.2.0
      • numpy 1.19.5
      • numba 0.53.1
      • OpenCV 4.5.0 (with CUDA)
      • pandas 1.1.5
      • scipy 1.5.4
