cv2 (opencv-python) intellisense not working #1993
Description
Activity
Sergio Pedri (@Sergio0694) IntelliSense works for me for
cv2. Based on the fact that PyLint is saying it can't findcv2I suspect that yourpip3command is not installing into the same Python environment you have selected for VS Code. If you're using a virtual or conda environment then usePython: Create Terminaland installcv2either using conda orpython -m pip install --upgrade opencv-python.Brett Cannon (@brettcannon) Hello, thank you for you reply. I've followed your advice, uninstalled the package from
pip3and installed it again usingpython -m pip install --upgrade opencv-python.Now it looks like VSCode does show the suggestions in the dropdown menu, but for some reason at the same time it also says it can't find any method inside the package. Here's a screen:
This is the error I'm getting in that screen:
[pylint] E1101:Module 'cv2' has no 'cvtColor' member
Is there something else I need to configure on my end? I'm not sure as to why it's correctly showing the methods from the suggestions box, while also marking them as errors in the line just above.
Thanks again![pylint] E1101:Module 'cv2' has no 'cvtColor' member
Please ensure the packages
pylintandopencv-pythonare installed in the same Python environment, the one used by VS Code extension. You can check what interpreter is used by VS Code by looking at the bottom left of the status bar.Note: If the problem persists, try running the linter from the command prompt manually, e.g.
pylint <filename.py>. If you get the same error reported, then please report this issue upstream inpylint.- locked as resolved and limited conversation to collaborators
on Jul 17, 2018 Solution as described in pylint-dev/pylint#2426
Add
--extension-pkg-whitelist=cv2to pylint's arguments e.g. via"python.linting.pylintArgs": ["--extension-pkg-whitelist=cv2"]

Hello, I'm opening a new issue as I saw the previous ones have been closed already and I couldn't post there. It looks like the cv2 intellisense suggestions don't work, and VSCode currently marks as errors all the calls to any method/member of the cv2 module. Here's a screen:
Steps to Reproduce:
pip3 install --upgrade opencv-pythonimport cv2and try to use any method from that packageDoes this issue occur when all extensions are disabled?: No, as I don't get any kind of suggestions this way, and pylint seems to be disabled entirely with this option.
Thanks!
