AttributeError: Can't get attribute 'VectorEnvFactoryConfig'

[kellyiss]

I install the habitat-lab and habitat-sim of the branch challenge-2023. However, when I try to train the ddppo baseline using the config objectnav/ddppo_objectnav_v2_hm3d_stretch.yaml, I came across this error:

AttributeError: Can't get attribute 'VectorEnvFactoryConfig' on <module 'habitat_baselines.config.default_structured_configs' from '/home/code/3dsemexp/src/habitat-lab-challenge-2023/habitat-baselines/habitat_baselines/config/default_structured_configs.py'>

Can you help check this?
