EDIT: I solved it. Turns out running as root is necessary for some reason
When training an RCNN or FastRCNN I get the following error:
Warning: An error occurred while using rcnnObjectDetector.proposeRegions to process /data/datasets/image.jpg:
im2uint8 requires a Image_Toolbox license
However, I have a license
license('test', 'Image_Toolbox')
ans = 1
and if I call checkout with the same function it succeeds. If I call the im2uint8 on the command windows, it works fine. Only inside the training function call does it have an issue.

Hi, please contact Technical Support (support@mathworks.com) to help resolve this. You shouldn't need to submit the job as root (and probably don't want to for several reasons).

Is your default profile for Parallel Computing Toolbox connected to a cluster ?
