2018-07-29 opencv, cannot find DLL

I recently faced an issue with opencv-python and python 3.7: import cv2 returned the following error:

ImportError: DLL load failed: Le module spécifié est introuvable.

Too configurations are working for me:

  • Python 3.6, OpenCV-Python 3.4.1, Windows Server 2012.

  • Python 3.7, OpenCV-Python 3.4.2, Windows 10.

Not working :

  • Python 3.6, OpenCV-Python 3.4.2, Windows Server 2012.

  • Python 3.7, OpenCV-Python 3.4.2, Windows Server 2012.

I guess I’ll have to recompile it to understand what is different.
