Issue installing opencv-python #54

Closed cwaeland closed 3 years ago

cwaeland commented 3 years ago

So one of my coworkers recently started using the opencv dependency. This project has a very large C component but thankfully they provide a number of binary wheels for different platforms.

For local development on macOS pip_install() has been able to install the correct wheel opencv_python-4.5.1.48-cp38-cp38-macosx_10_13_x86_64.whl. However, during our CI process pip_install() is instead downloading the source and compiling which can take over 15 minutes.

If I manually pip install on one of our CI instances (pip3 install opencv-python) it finds and downloads opencv_python-4.5.1.48-cp38-cp38-manylinux2014_x86_64.whl.

Any thoughts as to what might be going on here or how to debug?

Actually I was able to resolve by using the most recent commit of rules_pip. I suspect the updated version of pip helped.
