Hi, I am Amy and using pypy with python3.6.6. I need to import "python -m pip install opencv-python" to run the program and try to import with pypy like "pypy3 -m pip install opencv-python". However, it give an error: "Could not find a version that satisfies the requirement opencv-python (from versions: ) No matching distribution found for opencv-python You are using pip version 9.0.1, however version 19.0.2 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command." (by the way, I upgraded all the tools (pip and wheel) to the lastest version but they keep saying me to upgrade it). Do you have any idea to solve this problem? I need pypy to upgrade the speed of my program which is reading a large video and want to increase the average frame numbers. Thank you!
