TypeError: tuple indices must be integers or slices, not str

Hi， I have a little problem. when I run

python3 -m scripts.train --algo ppo --env MiniGrid-DoorKey-5x5-v0 --model DoorKey --save-interval 10 --frames 80000

It goes like

        image": preprocess_images([obs["image"] for obs in obss], device=device),
TypeError: tuple indices must be integers or slices, not str

which happened here:

        def preprocess_obss(obss, device=None):
            return torch_ac.DictList({
                "image": preprocess_images([obs["image"] for obs in obss], device=device),
                "text": preprocess_texts([obs["mission"] for obs in obss], vocab, device=device)
            })
        preprocess_obss.vocab = vocab

How should I fix it? Thx

I’ll look into this today

@saleml Should rl-starter-files be modified to work with the new version of gym-minigrid?
