AttributeError: 'NoneType' object has no attribute 'GetPath'

When I wanted to verify whether it was installed correctly and run python train.py algo=ppo headless=true wandb.entity=YOUR_WANDB_ENTITY, an error AttributeError: 'NoneType' object has no attribute 'GetPath' occurred

`Error executing job with overrides: ['algo=ppo', 'headless=true'] Traceback (most recent call last): File "/home/studj/anaconda3/envs/sim/lib/python3.10/site-packages/hydra/_internal/utils.py", line 220, in run_and_report return func() File "/home/studj/anaconda3/envs/sim/lib/python3.10/site-packages/hydra/_internal/utils.py", line 458, in lambda: hydra.run( File "/home/studj/anaconda3/envs/sim/lib/python3.10/site-packages/hydra/internal/hydra.py", line 132, in run = ret.return_value File "/home/studj/anaconda3/envs/sim/lib/python3.10/site-packages/hydra/core/utils.py", line 260, in return_value raise self._return_value File "/home/studj/anaconda3/envs/sim/lib/python3.10/site-packages/hydra/core/utils.py", line 186, in run_job ret.return_value = task_function(task_cfg) File "/home/studj/OmniDrones/scripts/train.py", line 51, in main base_env = env_class(cfg, headless=cfg.headless) File "/home/studj/Documents/rl/torchrl/envs/common.py", line 177, in call instance: EnvBase = super().call(*args, **kwargs) File "/home/studj/OmniDrones/omni_drones/envs/single/hover.py", line 122, in init super().init(cfg, headless) File "/home/studj/OmniDrones/omni_drones/envs/isaac_env.py", line 134, in init global_prim_paths = self._design_scene() File "/home/studj/OmniDrones/omni_drones/envs/single/hover.py", line 192, in _design_scene kit_utils.create_ground_plane( File "/home/studj/OmniDrones/omni_drones/utils/kit.py", line 84, in create_ground_plane collision_prim_path = prim_utils.get_prim_path( File "/home/studj/.local/share/ov/pkg/isaac-sim-2023.1.0-hotfix.1/exts/omni.isaac.core/omni/isaac/core/utils/prims.py", line 349, in get_prim_path return prim.GetPath() AttributeError: 'NoneType' object has no attribute 'GetPath'
