PyLint not recognizing cv2 members

This is from pylint. You can generate a pylint config file in the root of your project with this command: (I find this to be helpful if you work in a team or on different computers from the same repo)

pylint --generate-rcfile > ~/.pylintrc

At the beginning of the generated .pylintrc file you will see

# A comma-separated list of package or module names from where C extensions may
# be loaded. Extensions are loading into the active Python interpreter and may
# run arbitrary code.
extension-pkg-whitelist=

Add cv2 so you end up with

# A comma-separated list of package or module names from where C extensions may
# be loaded. Extensions are loading into the active Python interpreter and may
# run arbitrary code.
extension-pkg-whitelist=cv2

Save the file. The lint errors should disappear.

1. On VScode: CTRL + Shift + P
2. Choose "Preferences: Open Settings (JSON)"
3. Add this line into JSON file: "python.linting.pylintArgs": ["--generate-members"]

Done, it works for me

Note: Make sure you choose "Preferences: Open Settings (JSON)", not "Preferences: Open Default Settings (JSON)"

Setting File would look like

{
"workbench.iconTheme": "vscode-icons",
"python.dataScience.sendSelectionToInteractiveWindow": true,
"kite.showWelcomeNotificationOnStartup": false,
"python.dataScience.askForKernelRestart": false,
"python.dataScience.jupyterServerURI": "local",
"python.pythonPath": "/usr/bin/python3",
"workbench.colorTheme": "Monokai",
"vsicons.dontShowNewVersionMessage": true,
"python.linting.pylintArgs": ["--generate-members"] }

Try import cv2 like this: from cv2 import cv2.
