For example: running the arm_demo from Isaaclab_Doc

python source/standalone/demos/arms.py

But it still launch with the 4.0.0 version of isaacsim:

And Can i check my current using version of isaacsim and isaaclab in another way?(like by typing something in the Terminal and it outputs with the version of isaacsim and isaaclab).

And the isaacsim runs as expected:

${ISAACSIM_PATH}/isaac-sim.sh

${ISAACSIM_PYTHON_EXE} -c "print('Isaac Sim configuration is now complete.')"

output:

Warning: running in conda env, please deactivate before executing this script
If conda is desired please source setup_conda_env.sh in your python 3.10 conda env and run python normally
Isaac Sim configuration is now complete.

But this doesn’t went well:

# checks that Isaac Sim can be launched from python
${ISAACSIM_PYTHON_EXE} ${ISAACSIM_PATH}/standalone_examples/api/omni.isaac.core/add_cubes.py

Isaacsim was launched but crashed after hanging for a while.

According to the log,It launched with the correct 4.2.0version.
But then i try with :

python source/standalone/demos/arms.py

it still says i was running with 4.0.0 version of issacsim from the log:
