Hello,

I am running python3.9.0 and after installing cv I get the following error: It looks like it's trying to allocate memory size = 18446744071760121856 ? Please help. Thank you.

after installing cv

what did you do, exactly ? os ?

File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/numpy/__init__.py"

looks like a numpy problem, not an opencv one

I installed cv, using

pip install opencv-python

I am on macOS 10.15.2

opencv does not maintain any pip binaries

Otherwise report this to the vendor that provided NumPy. RankWarning: Polyfit may be poorly conditioned

that's what you probably have to do.
