Error trying to open generated scene in Unity.

[ZheningHuang]

I tried to follow this guide to view the generated scene in Unity.

Here is what I have in Unity once I open the ai2thor project:

Then, I attempted to run python connect_to_unity.py --scene a_living_room-2024-04-06-11-58-33-174468/a_living_room.json but encountered the following errors.

Any suggestions?

Traceback (most recent call last):
  File "/Users/zhao/miniconda3/envs/holodeck/lib/python3.9/site-packages/ai2thor/wsgi_server.py", line 48, in queue_get
    res = que.get(block=True, timeout=queue_get_timeout_per_try)
  File "/Users/zhao/miniconda3/envs/holodeck/lib/python3.9/queue.py", line 179, in get
    raise Empty
_queue.Empty

During handling of the above exception, another exception occurred:

Hello, may I ask how you resolved this issue? I am currently encountering the same error.

Hi, I followed the instructions at https://github.com/allenai/Holodeck#load-the-scene-in-unity closely and managed to get it working. I forgot to do step 3 in my first try.

Thank you for your reply. I have completed everything as instructed, but I am still encountering the error mentioned above.

Hi, I think this error is due to the fact that your Python code cannot link with the Unity engine after a long time of trying. So, I guess there's something wrong with your Unity installation?

Maybe try this and see if it can open Unity first:

Hi Zhening. I spent weeks trying to connect to Unity and load the scene, but it did not work. And it looks like you are using Miniconda, could you please get me more info regarding the sys, env and version you are using?

Because I am using ubuntu 24.04 and unity 2020.3.25, but I couldn't open unity without sandbox and everytime when I load ai2thor in it, I have complier issues. I think it is because Unity may not be supported in ubuntu 24,04.

I would appreciate any information. Thanks:)

Hi, I was using a Mac and had no problem following the instructions given by the author. Maybe @ the author team for support?
