Hi,  
My team is using CV2 instead of PIL to load images and we are running into an issue where the cv2 system dependencies are not installed. Besides we also have a couple of python libraries we would like to install beforehand.

I understand we can build our own docker image but when we actually submit the code it won’t be tested with our docker image right? So we were wondering if there is a way to install the dependencies when doing make test-submission.

Hi @andohuman,
