No graphical output using Xming Server #851

Open mariiak2021 opened 3 years ago

mariiak2021 commented 3 years ago

Hi all,

I'm trying to use Ai2Thor on a Debian-based remote-server with GPU, but without GUI, therefore I use Xming server with X11 forwarding to display work on my laptop display (laptop OS is Windows). It perfectly works with many algorithms - the display is opened correctly, but with Ai2Thor I don't receive any error and still don't see any output display with simulator.

The only line, which I get after executing Controller example (https://ai2thor.allenai.org/ithor/documentation/initialization) is:

Found path: /home/mkhan/.ai2thor/releases/thor-Linux64-a4bcfa890c748c0e9e04de9dc2062bb6a5d1bf3e/thor-Linux64-a4bcfa890c748c0e9e04de9dc2062bb6a5d1bf3e

Then no output more at all. Can someone please help me to understand what can be wrong?

same problem, did you solve that?

We have another option for rendering without a graphical display, please try the following code:

import ai2thor.controller
from ait2thor.platform import CloudRendering

controller = ai2thor.controller.Controller(platform=CloudRendering)

You will need to have the package libvulkan installed for this to work.

sudo apt-get -y install libvulkan1

Hi @RupertLuo I solved the problem using VcXsrv verver instead of XMing. While launching display with VcXsrv unselect the option "Native opengl". This worked for me.
