Autocomplete is still not working on pycharm.

[zihaomu]

Expected behaviour

Autocomplete is still not working on pycharm.

Steps to reproduce

Test it with Apple M1, PyCharm.
And the opencv-version:
4.7.0.68 and 4.7.0.72 are both not working.

Issue submission checklist

• This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• I'm using the latest version of opencv-python

Workaround for Windows is to create a hard link from the site-packages folder to the binary file mentioned in the linked discussion.

be aware that 'mklink' is only available in the old windows command line.

cd <your_venv_location>/Lib/site-packages
mklink /H cv2.pyd cv2\cv2.pyd

On MacOS (M1) I had to symlink the cv2.abi3.so file into the site-packages dir:

cd <venv>/lib/python3.8/site-packages
ln -s cv2/cv2.abi3.so

cd <venv>/lib/python3.8/site-packages
ln -s cv2/cv2.abi3.so

Thanks, this also does the trick on my Intel Mac. I ran:

ln -s /Users/kyle/PycharmProjects/animation-processing/venv/lib/python3.11/site-packages/cv2/cv2.abi3.so /Users/kyle/PycharmProjects/animation-processing/venv/lib/python3.11/site-packages/

And then I also needed to invalidate caches in PyCharm before autocomplete started working (File -> Invalidate Caches)

@kylefmohr I'm doing this in IDEA where the symlink gets picked up automatically.

But an issue with the symlink is pipenv often seems to clear it away and I have to re-add the symlink fairly often.

I now had access to a test system with Linux/AMD64, and the workaround also works there.

Linux and Mac (thanks to @damonmaria):

cd <your_venv>/lib/<your_python_version>/site-packages
ln -s cv2/cv2.abi3.so

Windows (old windows cmd line)

cd <your_venv_location>/Lib/site-packages
mklink /H cv2.pyd cv2\cv2.pyd

Linux and Mac (thanks to @damonmaria):

cd <your_venv>/lib/<your_python_version>/site-packages
ln -s cv2/cv2.abi3.so

I do find you have to recreate it fairly often (with pipenv anyway). But still worth it.

I normally use venv, which does not appear to have this problem.

Fixed in:

• Python typing stub generation opencv#20370
• Try to add pyi files to package #853

[Gornoka]

Thanks a @asmorkalov lot for working on a fix for that, do you happen to know when we can expect the next release of the Python package?

[asmorkalov]

In good luck - next week. Main OpenCV release will happen first, OpenCV-Python in a couple of days.
