Looks like there is no opencv-python for Python 3.10… yet. Be patient.

This issue is being tracked already: https://github.com/opencv/opencv-python/issues?q=3.10

I have installed OpenCV with Python 3.10 on M1 using pip install opencv-python

I hope it will work on Windows and Linux as well.

Answer 3

pip install opencv-python worked for me.

I had a clean environment (anaconda prompt), did not even install pip, but it still worked.
My steps:

conda create -n envname
conda activate envname
conda install -c anaconda numpy (I needed numpy, it installed python 3.10)
conda install opencv-python (did not work, prompt adviced me to search in other channel.)
pip install opencv-python (as sharmaji adviced)

Everything works and my program that did not work bevore because opencv was missing, now works to.

Numpy 1.22.3 , opencv-python 4.6.0.66 and python 3.10.4

A lot more as well, but that’s outside the scope of this topic.
