Visualization Ai2THOR scenes on Ubuntu

[moorthyrahul]

Hey, I'm trying Ai2THOR for the first time. I installed it via pip on Ubuntu 18.04. After installing, I wanted to verify the installation using the following (via python3.7 terminal):

from ai2thor.controller import Controller
controller = Controller(scene="FloorPlan10")
event = controller.step(action="RotateRight")

There's no output after the controller command and I'm unable to visualize the scene. Also in the locally downloaded ~/.ai2thor directory, I don't see any game environment containing the 3D scenes. Has anyone else faced this issue?

Thanks in advance!

Hi @moorthyrahul,

Can you try something like printing the event:

from ai2thor.controller import Controller
controller = Controller(scene="FloorPlan10")
event = controller.step(action="RotateRight")
print(event)

or saving the RGB image frame:

from ai2thor.controller import Controller
from PIL import Image
controller = Controller(scene="FloorPlan10")
event = controller.step(action="RotateRight")
Image.fromarray(event.frame).save("frame.png")

Hi @mattdeitke,

Thank you for your response. I tried that, but still unable to view the output scene from the controller (below image) and there's no further feedback. I'm using python 3.6, Ubuntu 18.04 and installed Ai2THOR via pip install.

Kindly let me know if there's a setup issue from my end!

Are you running on a headless machine (i.e., a machine without a monitor attached) by chance?
