Getting Python Working with Isaac Sim Launcher App

Hi There
I am trying to setup Python environment to work with Isaac Sim launched by Omniverse launcher. I couldn’t find " Python mini app" nor the root “_build/linux-x86_64/release” so that I run
./ -m pip install -r python_samples/requirements.txt
Could you please clarify the steps on how to setup Python with the launcher?


Hi, you can follow these step to run that command:

  1. Launch Isaac Sim from the Omniverse Launcher.
  2. On the Isaac Sim App Launcher, click the Open in Terminal button. A terminal window should pop-up
  3. Run ./ -m pip install -r python_samples/requirements.txt

Thanks @Sheikh_Dawood for the prompt response.
I actually did that and then tried running some sample code but keep getting various errors:

  1. tried calling Jetbot sample with this:
    ./ python_samples/jetbot/

here is the error message:

Traceback (most recent call last):
File “python_samples/jetbot/”, line 3, in

There was an error running python

  1. tried the second method through a conda environment and ran:
    python python_samples/jetbot/

and here is the error:

Traceback (most recent call last):
File “python_samples/jetbot/”, line 1, in
import carb
ModuleNotFoundError: No module named ‘carb’

which probably means that the path to the modules are not set.

Please advise.


To run the JetBot sample, run:
./ python_samples/jetbot/
