Questions about EXP_PATH and moudle lazy_moni

[Eressss]

Hi, my system is Ubuntu 20.04, with RTX 3090 and CUDA version 12.1. I installed omnigibson v1.1.1 with pip followed the instrction on official website. The version of Isaac Sim is 4.1.0-rc.7+4.1.14801.71533b68.gl. I find that the EXP_PATH is not automatically set, is it correct to set it like this: EXP_PATH= ..../anaconda3/envs/behavior1k/lib/python3.10/site-packages/isaacsim/apps ? And when I run the command python -m omnigibson.examples.robots.robot_control_example --quickstart, I encounter the following error:

Traceback (most recent call last):

    raise AttributeError(f"module {self.__name__} has no attribute {name}") from None
AttributeError: module lazy_omni has no attribute log

Is this caused by the wrong version of the module lazy_omni? But I didn't install this module manually. Please help me with these problems ,thanks!

[cgokmen]

There is no module lazy.omni, essentially the lazy module is a magic module that we use to delay all omniverse-dependent imports to after Omniverse is launched, at which time these modules will be available because of Omniverse updating the python path. So omni.log is not available is what it's saying which does indeed point at Omniverse not launching correctly.

Re: EXP_PATH, you should not have to set this. Why do you think you need to? I understand you did a pip install (make sure you ran python -m omnigibson.install as in the installation steps - did you?), after that open a Python interpreter and run import isaacsim to check the installation was successful. If it was, that import will automatically set the EXP_PATH variable for you.

Please send us the full output log you see when you run the robot control example if you are still having issues. The real issue appears in the log far above this trace you posted.

Installed isaacsim 4.1.0 by Omniverse Launcher, and omnigibson v1.1.1;
import omnigibson && import isaacsim works fine,
but when creating env as the 'my_first_env.py' in https://behavior.stanford.edu/omnigibson/getting_started/quickstart.html#defining-a-task

env = og.Environment(cfg)

Errors occurred:

Any ideas?

[Eressss]

Please make sure you have installed all units successfully. I set it up in a new virtual environment with the same version and never encountered this error again. The first time I was interrupted by the system when installing omnigibson because of lack of memory and It seems that the system mistakenly thinks it has installed all the files about omnigibson.

Hi Eressss, I have another isaacsim version 4.2.0 installed by a python venv, which works normal, could this be the matter? # And omnigibson was installed by miniconda.

[Eressss]

I don't think so, since the version of isaacsim I have is 4.1.0.0. But omnigibson is installed by pip.
