Object error in examples

[ConnerQiu]

Great that the new version is released. The installation process is simple and clean! when I run both of the examples secen_selector and robot_control, I got the same error meassage, it seems like relates to the method "self.disable_collisions_for_fixed_objects()" is used in wrong objects. I am using Isaac Sim (2022.2.1)

Before it shut down, I got serval warning, I list them all in sequence here( they happened in different places): Is these warning important for the simulator to function properly?

Hi, we just discovered the problem today. This should be fixed in v0.1.0 (which we released today). Please use the new docker image or pull from the main branch if you are installing from source.

Isaac Sim does spill out a lot of warnings, so in general if those do not crash OG you can safely ignore them.

Also, we suggest you use 2022.2.0 instead since loading large OmniGibson scenes would cause segfault in 2022.2.1 (though if you don't encounter such problem when using the new version then you should be fine).

[ConnerQiu]

Great. Highly efficient! Also thanks for you advice, I am considering switching to 2022.2.0 to avoid issues in the future~
