Using OpenCV with OpenSesame

Hi folks,

I've been trying to get to the point where I can use OpenCV ('import cv2') with OpenSesame.

I was getting this error initially because I was using 64 bit version with OpenSesame (I copied the relevant files into site-packages):

ImportError: dll load failed: %1 is not a valid win32 application

I've now reinstalled Anaconda (32 bit) and pip installed the 32 bit version of OpenCV and copied the files over to OpenSesame site-packages again, after deleting the 64 bit ones.

The error I'm getting now when I try to 'import cv2' is:

 ImportError: DLL load failed: The specified module could not be found

I've used 'imp.find_module("cv2")' and it is showing cv2.pyd in the OpenSesame site-packages, so not sure why it isn't being found.

Any idea why this is happening?

Thanks as always,

    Hi folks,

    My colleague solved the issue. Please see his comments below:

    "The best way to complete the installation is to install the package from within OpenSesame.

    This link gives the detailed instructions to do this using 'pip':

    In short,

    In the debug terminal: import pip

    followed by: pip.main(['install', 'opencv-python'])

    That should install OpenCV in OpenSesame.

    Note: You need to run OpenSesame as Admin in Windows or using sudo in Mac/Linux in order to allow installation."
