Issac sim python example failed!

Hi @nvidiaAI

You need to instantiate the SimulationApp class before importing all other Omniverse packages/modules as indicated in the documentation

https://docs.omniverse.nvidia.com/app_isaacsim/app_isaacsim/manual_standalone_python.html?#simulationapp

Any Omniverse level imports must occur after the class is instantiated. Because APIs are provided by the extension/runtime plugin system, it must be loaded before they will be available to import.
