For a project I’m working on I’m trying to create a dataset using the Isaac Sim python API.
I’ve decided to use the sample dataset generator script (under offline_generation) as my starting point.
There I’ve added a class method to add DR components to the scene, and have been able to get a lighting component working. However, both trying to implement a transform component or a visibility component still gives me error messages.
Transform component:
for the transform component I added the following function:
for i in range(cam_ymin, cam_ymax): camera_points_list.append(Gf.Vec3f(-250, i, 500)) result, prim = omni.kit.commands.execute( "CreateTransformComponentCommand", prim_paths="/Root/Camera_01", target_points=camera_points_list, enable_sequential_behavior=False )
This gives me the following error:
2021-09-16 10:44:06 [252,788ms] [Error] [carb.python] Failed to execute a command: CreateTransformComponentCommand.

It seems the prim path is incorrect, but I checked it multiple times. I also tested it with a mesh in the scene instead of the camera, but that led to the same error.
Visibility component:
for the visibility component I added the following function:
result, prim = omni.kit.commands.execute( 'CreateVisibilityComponentCommand', prim_paths=['/Root/Group_05/SM_PaletteA_359/SM_PaletteA_01'], num_visible_range=(0, 0), duration=1.0, include_children=True, seed=12345 )
This gives me the following error:
2021-09-16 10:25:46 [237,605ms] [Error] [omni.usd] Runtime Error: in _SetValueImpl at line 6028 of /buildAgent/work/ca6c508eae419cf8/USD/pxr/usd/usd/stage.cpp – Empty typeName for </Root/Group_05/SM_PaletteA_359/SM_PaletteA_01/subset.visibility>
for reference, the lighting component which does work:
light_prim_path = “/Root/SM_LampCeilingA_23/RectLight”
result, prim = omni.kit.commands.execute(
“CreateLightComponentCommand”,
light_paths=[light_prim_path],
first_color_range=(1, 1., 1.),
second_color_range=(1.0, 1.0, 1.0),
intensity_range=(0, 70000.0),
temperature_range=(1500.0, 6500.0),
enable_temperature=True,
duration=1.0,
include_children=False,
)
I’ve looked through the forums but wasn’t able to find any other posts with these error messages.
If some extra info is needed, just let me know.
The script I’m using:
