Handing mission space in Babyai env about stable-baselines3 HOT 6 CLOSED

Hey, please provide the system info
As far as I remember, the babyai mission is a str right?

from stable-baselines3.

Here is the system info as requested:

• OS: Linux-6.5.0-28-generic-x86_64-with-glibc2.35 # 29~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Apr 4 14:39:20 UTC 2
• Python: 3.11.5
• Stable-Baselines3: 2.2.1
• PyTorch: 2.1.0+cu118
• GPU Enabled: True
• Numpy: 1.24.3
• Cloudpickle: 2.2.1
• Gymnasium: 0.29.1
• OpenAI Gym: 0.26.2

Yes you're correct it should be a string based on the babyai level, but image and direction key are not causing the issue for sure. Even on simply Using this code

env  = gym.make("BabyAI-PickupLoc-v0")
model = PPO("MlpPolicy", env, seed = 42, verbose=1)
model.learn(50000)
env.close()

throws the same error.

Text observation is not supported. Technically, to make it work, you can convert the text to a discrete value, for example.
That said, depending on what you're trying to do and show, this solution may not be relevant.

Can I convert text into a vector embedding and them might be able to use it?

it should work yes
