I’m having an issue installing OpenCV for python3 (cv2) on Debain 8.7.
Both commands,
sudo pip install opencv-python
sudo pip3 install opencv-python
return the error,
Collecting opencv-python
Could not find a version that satisfies the requirement opencv-python (from versions: )
No matching distribution found for opencv-python
I tried this on many of the other debian versions including the most updated versions, and versions pre-8.7 and have been unable to make it work anywhere.
python3 opencv is not available in jessie or stretch. I'm actually backporting opencv 3.2 from buster to stretch as I type this in order to get python3 support. It looks like you are using jessie though.
