The error of scene_loader.get_scene_from_token(token)
Hello, I am running this part of the tutorial code
token = np.random.choice(scene_loader.tokens) scene = scene_loader.get_scene_from_token(token)
The following error occurs：
`TypeError Traceback (most recent call last) Cell In[60], line 2 1 token = np.random.choice(scene_loader.tokens) ----> 2 scene = scene_loader.get_scene_from_token(token)

TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType`
I don't know what the reason is, can you give me some help?
