Unable to run 'python3 demo.py --env_config objectgoal_suncg_mf'

Hello, I wanted to try to run python3 demo.py --env_config objectgoal_suncg_mf. However, I encountered the following problem:

jin@jin-System-Product-Name:~/minos-0.6.x/gym$ python3 demo.py --env_config objectgoal_suncg_mf

Then I comment the following two lines:

if 'goalObservations' in result:
            del result['goalObservations']

However, I still encountered the following errors:

Please give me some help! Thank you very much!
