1 month ago Found a fix - https://github.com/isaac-sim/IsaacLab/issues/257#issuecomment-2352011015 - just need to prepend the snippet mentioned in the linked issue to any "standalone" script that you want to run. Pasting the snippet (which needs to be prepended to run standalone scripts) here for added convenience -
# Launch Isaac Sim Simulator first.
import argparse
from omni.isaac.lab.app import AppLauncher
# add argparse arguments
parser = argparse.ArgumentParser(description="My dummy script.")
# append AppLauncher cli args
AppLauncher.add_app_launcher_args(parser)
# parse the arguments
args_cli = parser.parse_args()
# launch omniverse app
app_launcher = AppLauncher(args_cli)
simulation_app = app_launcher.app
# Rest everything follows.
When I try to run the following -
from omni.isaac.lab.envs import DirectRLEnvI get the following error -
My machine specfications are the following -
I followed all the installation instructions here - https://isaac-sim.github.io/IsaacLab/main/source/setup/installation/pip_installation.html#
My conda environment is the following -
Could someone help me out here? Thanks in advance!
