Anytime I try to install a package using the package manager I get this error

[Firepup650]

Since that is an error with urllib3, try this:

@Firepup650

That’s a urllib3 error (Removed the ability to do that in 2.0.0), run:

pip install --force-reinstall urllib3==1.26.15
poetry add urllib3==1.26.15

The second one ensures poetry doesn’t update it and break something unintentionally.

And as for the opencv template, you can find it here.
