Detailed Description

I tried to creating an empty scene by first clicking “python.bat” and type import isaacsim then type isaaclab, then paste codes for creating an empty scene, which is:
import argparse
from isaaclab.app import AppLauncher
parser = argparse.ArgumentParser(description=“Tutorial on creating an empty stage.”)
AppLauncher.add_app_launcher_args(parser)
args_cli = parser.parse_args()
app_launcher = AppLauncher(args_cli)
simulation_app = app_launcher.app

I am not sure is this because RTX2060 is too low to run isaac sim4.5.0. Or I have to change a laptop such RTX4060 to run it.
