“Could not find a version that satisfies the requirement opencv-python”

Question

I am struggling with Jetson TX2 board (aarch64).

I need to install python wrapper for OpenCV.

I can do:

$ sudo apt-get install python-opencv
         


        

Answer 1

Another problem can be that the python version you are using is not yet supported by opencv-python.

E.g. as of right now there is no opencv-python for python 3.8. You would need to downgrade your python to 3.7.5 for now.

Answer 2

pip doesn't use http://www.lfd.uci.edu/~gohlke/pythonlibs/, it downloads packages from PyPI.

The problem is that you have an unusual architecture; pip cannot find a package for it and there is no source code package.

Unfortunately I think you're on your own. You have to download source code from https://github.com/skvark/opencv-python, install compiler and necessary libraries and compile OpenCV yourself.

Answer 3

A way to do this is to install Anaconda on your computer.

Then you should be able to do:

pip install opencv-python

or

conda install opencv
