the command is
“./python.sh tools/composer/src/main.py --input parameters/warehouse.yaml --output */datasets/warehouse --num-scenes 10 --mount ~/workspaces/isaac/”
the error is
"ImportError: /home/sota/.local/share/ov/pkg/isaac_sim-2021.2.1/kit/extscore/omni.usd.libs/bin/libjs.so: undefined symbol: _ZN32pxrInternal_v0_20__pxrReserved__18
I researched about this and found a report that several packages with Isaac depend on an instance of SimulationApp, and the dependent packages must be imported after the instance is created, or it will result in an ImportError.
Therefore, we edited the executable file tool/composer/main.py and changed it so that the SimulationApp instance is created first.
First, open the relevant file in an editor.
