[Bug Report] [Warning] [omni.client.python] Detected a blocking function. This will cause hitches or hangs in the UI. Please switch to the async version:
#701
I run the demo script from source/standalone/demos/quadrupeds.py in VSCode integrated Terminal (command line & debugger), and get the warnings "[omni.client.python] Detected a blocking function. This will cause hitches or hangs in the UI. Please switch to the async version:"
The python program is blocked and does not run as expected.
This problem does not appears when I run this script in system Terminal.
Steps to reproduce
Open the VSCode at the IsaacLab root directory: cd /path/to/IsaacLab && code .
Activate Conda virtual environment and setup the conda_python: conda activate isaaclab && source /home/sim/.local/share/ov/pkg/isaac-sim-4.0.0/setup_conda_env.sh
run the demo python script: python source/standalone/demos/quadrupeds.py
