Unable to run custom ros2 nodes in isaac sim

[sandipsharan]

Any idea on how to solve this issue? I still have my system taking on Python3.10 as the base and not Python3.11. I followed the instructions given in the official document. Can someone point me to the correct method of running a custom ROS2 node to teleop the object in IsaacSim?

Operating System: Ubuntu 22.04
Isaac Sim Version: 5.0
ROS2 Version: Humble
GPU Information: GeForce RTX4090

Please refer to 'https://docs.ros.org/en/humble/Guides/Installation-Troubleshooting.html#import-failing-without-library-present-on-the-system' for possible solutions

Additional Info: I'm trying to teleop a Crazyflie object in my simulation. I tried to replicate the documentation given for driving a turtlebot. Any help regarding this would be greatly appreciated.

Did you do the steps for Enabling rclpy, Custom ROS 2 Packages, and Workspaces with Python 3.11: https://docs.isaacsim.omniverse.nvidia.com/latest/installation/install_ros.html#enabling-rclpy-custom-ros-2-packages-and-workspaces-with-python-3-11?

Also 5.1.0 has been released. Please try that out.
