Fallback handler could not load library libadvapi32.dll

[zkytony]

I am running ai2thor on a remote machine (AWS ec2 instance running Ubuntu 18.04). I'm using version 2.7.2. When I try to run the following program

from pprint import pprint
import ai2thor.controller
import cv2

if __name__ == '__main__':
    controller = ai2thor.controller.Controller(scene='FloorPlan28')
    event = controller.step(action='RotateRight')
    pprint(event.metadata['agent'])
    cv2.imwrite("output.png", event.cv2img)

I got a bunch of messages saying

Fallback handler could not load library /.../.ai2thor/thor-Linux64-a6674babc132c5d63d18c82a0e14c01d236aa981/thor-Linux64-a6674babc132c5d63d18c82a0e14c01d236aa981_Data/Mono/libadvapi32.dll

It is indeed the case that Mono does not exist under the thor-Linux64-a667..._Data folder. There is only MonoBleedingEdge. This is an issue.

This message didn't appear to affect the program; it still saved an image. I wonder if that will affect the rendering of the image.
