OK, thanks a lot!

Hi, It is not tested in ROS Noetic version. You can go through the URDF files to fix this problem. I think there is something updated in ROS Noetic when...

Hi, This may be related to the Lidar sensor. Maybe the link or joint's name is wrong due to the difference of parse xarco file in Noetic.

From README of gym: 2019-02-06 (v0.11.0) remove gym.spaces.np_random common PRNG; use per-instance PRNG instead.

If I load an usd file which contains lots of objects, how to label these objects one by one automaticly

like the function **apply semantic data using prim names** in https://docs.omniverse.nvidia.com/isaacsim/latest/replicator_tutorials/tutorial_replicator_getting_started.html

Thanks, semantic tags should solve the problem. Is it possiable to run the function from "Semantics Schema Editor" by python code in orbit? The GUI has an "add" button which...

I'm not sure if the semantic tags work well. I try the code "source/standalone/tutorials/04_sensors/run_usd_camera.py", adding the "semantic_segmentation" option to camera and save the images. ``` camera_cfg = CameraCfg( prim_path="/World/Origin_.*/CameraSensor", update_period=0,...

Just update the latest code. Works well now, thanks! I believe this commit fix this bug: 8dea21a8ac805ab4dd804fc9927110f3c27f8b3b

Although the semantic camera is correct, the semantic tag is still wrong. Its semantic label is the path in the simulation, not the value set when generating
