Find-GCP module

Developers Chat
#1

Hi,
I am trying to wite a module (pipeline stage) to automatically run ArUCo detection based on find-gcp work.
In order to do so I think I need to add a dependency to opencv but I did not managed to do it. I have added the following in the requirements.txt file:

opencv-python-headless
opencv-contrib-python-headless

But when executing the run.bat (I am under windows dev env) I have the following output:

['D:\\dev\\tests\\ODM_tools\\ODM_fork', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\venv\\lib\\site-packages\\cv2\\python-3.8', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\venv', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\python38\\python38.zip', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\python38\\DLLs', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\python38\\lib', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\python38', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\venv\\lib\\site-packages', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\SuperBuild\\install/lib/python3.9/dist-packages', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\SuperBuild\\install/lib/python3.8/dist-packages', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\SuperBuild\\install/lib/python3/dist-packages', 'D:\\dev\\tests\\ODM_tools\\ODM_fork\\SuperBuild\\install/bin/opensfm']

ImportError: ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.

Any hint or info on what I am doing wrong here ?
