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!
Apparently, your issue
"Could not find a version that satisfies the requirement opencv-python (from versions: ) is related to pip, and the suggested fix was to upgrade your pip ( https://pypi.org/project/opencv-python/). You may want to start with that. You will also need to find how opencv plays with pypy.

This happens because opencv decided to release only binary wheels on PyPI, as you can see here; note that the only files available are *.whl: https://pypi.org/project/opencv-python/#files The great advantage of binary wheels is that you don't have to recompile the package yourself; however, they are tied to a particular combination of OS/python version: opencv didn't release any binary wheel for PyPy, so pip cannot find any. When pip cannot locate a wheel, it tries to download a source package (like .tar.bz2 or .zip) and compile it on the fly; however, opencv didn't release any, that's why you get the error. Your best bet to have opencv on PyPy is to clone the source repo from github and run setup.py yourself: $ git clone https://github.com/skvark/opencv-python $ cd opencv-python $ pypy3 setup.py install ciao, Anto
