Hi everyone,

I have MacOS 10.14. I’m trying to install opencv in the python interactor by this code:

from slicer.util import pip_install
pip_install(“opencv”)

I get this error:

ERROR: Could not find a version that satisfies the requirement opencv (from versions: none)
ERROR: No matching distribution found for opencv
WARNING: You are using pip version 20.1.1; however, version 20.3.3 is available.
You should consider upgrading via the ‘/Applications/Slicer.app/Contents/bin/./python-real -m pip install --upgrade pip’ command.
Traceback (most recent call last):

subprocess.CalledProcessError: Command ‘[’/Applications/Slicer.app/Contents/bin/…/bin/PythonSlicer’, ‘-m’, ‘pip’, ‘install’, ‘opencv’]’ returned non-zero exit status 1.

Also regarding the Warning that I get for the update for pip when I open the python real, it is not editable to be able to put this code:

/Applications/Slicer.app/Contents/bin/./python-real -m pip install --upgrade pip

Thanks for your help.
