Hi,
I found a problem while using cv2. In my code, I already imported cv2
and installed pip install opencv-python already, however, it gives
following error.
Collecting cv2
Could not find a version that satisfies the requirement cv2 (from
versions: )
No matching distribution found for cv2.
When I try with python, it is working well, however, when I try with
pypy3, it is not importing cv even though there is a opencv-python in
the site-packages.
Please help me with this error! I have been working on this error for
a week.
Hi Amy. Thanks for trying PyPy. Since PyPy is an alternative
implementation of the python runtime, it needs a spearate installation
of all the python packages, it cannot share with the usual python
(formally known as cpython since it is written in C). If you run `pypy
-c "import sys; print(sys.path)"` you will see where it keeps its
site-packages, which is different than `python3 -c "import sys;
print(sys.path)"`.
As for opencv, it does not provide binary builds for pypy on pypi, you
will have to build from source. You can read more about it here
https://pypi.org/project/opencv-python/
