Thanks for your wonderful work! I want to load task-related config file such as //omnigibson/data/og_dataset/scenes/Beechwood_0_garden/json/Beechwood_0_garden_task_make_a_milkshake_0_0_template.json. I refer to the code of /omnigibson/examples/action_primitives/wip_solve_behavior_task.py and modify the task name.

The code I run is below:
code.txt

The log I get is below:
log.txt

I found only when I use the one and only scene and task in the example, I can success. If I try other scenes or tasks, there will be the following errors:

And the following error:

or

"ValueError: invalid literal for int() with base 10: '0.0'"

Actually, I have already download the dataset.

I will appreciate it so much If you can help me!

Sorry for the late response. The issue in the title is a spurious warning that is safe to ignore. The second issue re: pymeshlab stems from a library in your conda environment that includes an incorrect version of Qt that prevents pymeshlab from launching. This only affects cloth objects which pymeshlab is used for. I recommend reinstalling with a clean conda environment.
