Hi Community,
The Isaac Lab Reinforcement learning sample, Running Existing Scripts — Isaac Lab documentation, errors when executing on windows with:
Traceback (most recent call last):
File “C:\Users\tnrad\Isaac\IsaacLab\source\standalone\workflows\sb3\train.py”, line 41, in
app_launcher = AppLauncher(args_cli)
File “C:\Users\tnrad\Isaac\IsaacLab\source\extensions\omni.isaac.lab\omni\isaac\lab\app\app_launcher.py”, line 113, in init
self._create_app()
File “C:\Users\tnrad\Isaac\IsaacLab\source\extensions\omni.isaac.lab\omni\isaac\lab\app\app_launcher.py”, line 568, in _create_app
self._app = SimulationApp(self._sim_app_config, experience=self._sim_experience_file)
File “C:\Users\tnrad\Isaac\IsaacLab_isaac_sim/exts/omni.isaac.kit\omni\isaac\kit\simulation_app.py”, line 250, in init
from omni.kit.window.title import get_main_window_title
ModuleNotFoundError: No module named 'omni.kit.window.title
The issue is this code in the init function in the “_isaac_sim/exts/omni.isaac.kit/omni/isaac/kit/simulation_app.py”:
from omni.isaac.version import get_version
from omni.kit.window.title import get_main_window_title
window_title = get_main_window_title()
app_version_core, _, _, _, _, _, _, _ = get_version()
window_title.set_app_version(app_version_core)
commenting it out resolved the issue.
May be related to this issue, Cannot import omni.isaac.core - #2 by toni.sm
I’m interested to learn more on why this causes an issue.
