I'm use pyrightconfig json file and install cv2.
Can't prompt correctly for cv2.imread or cv2.imwrite
Sorry, my english is not good.
我已经安装了cv2 包 在 test 环境下，并且使用了pyrightconfig.json 文件。
现在问题是无法正常提示cv2的候选项，例如 imread imwrite,这些都无法正常提示。
不过其他包（tensorflow numpy）都能正常提示

Issue is here: microsoft/pylance-release#138

Now there are two solutions.

  1. compile the opencv from source
  2. If you have downloaded like pip install opencv-python then follow these two steps
    • pip install mypy
    • stubgen -m cv2 -o {cv2-package-folder} (In my case it is /home/soumya/anaconda3/lib/python3.7/site-packages/cv2)

I have tested the step 2 and it works.

I needed to modify the stubgen command for this to work.

cd {to your cv2 directory}
stubgen -m cv2 -o .
mv cv2.pyi __init__.pyi
