Hi guys,  
I am facing some issues with my jetson Xavier NX. Actually I want to build OpenCV in that with python 3.7 and CUDA support. When I’m trying to install the OS using SDK manager I am getting python 3.6 with CUDA 10.2, Cudnn 8.2 and I can build OpenCV on top of that. But I want to build OpenCV with CUDA support for python 3.7. If I am upgrading my python version form 3.6 to 3.7, I am not able to use OpenCV that has been built over python 3.6.  
Can you help me with providing some documents that can help me in doing these changes.

Hi,

Please find below an example of building OpenCV with a custom Python version:

> Hi, You can modify the CMake command to build the OpenCV library for python 3.7. For example, below are steps for building OpenCV with python 3.9. \*\* Install NumPy for python 3.9 $ sudo -H python3.9 -m pip install numpy --upgrade numpy \*\* Update CMake command for python 3.9 [https://github.com/AastaNV/JEP/blob/master/script/install\_opencv4.6.0\_Jetson.sh#L62](https://github.com/AastaNV/JEP/blob/master/script/install_opencv4.6.0_Jetson.sh#L62) $ cmake \ -D PYTHON\_LIBRARIES=/usr/lib/python3.9/config-3.9-aarch64-linux-gnu/libpython3.9.so \ -D PYTHON3\_EXECUTABLE=/usr/bin/python3…

Thanks.
