Is there some errors with the actions in the Ms-Pacman dataset?

[hutchinsonian]

I downloaded $store$_action_ckpt.10.gz and $store$_observation_ckpt.10.gz in atari-replay-datasets/dqn/MsPacman/1/replay_logs.
I found that action and observation do not match.
Specifically, the first 10 actions are array([2, 2, 2, 2, 6, 2, 2, 7, 7, 7], dtype=int32). And I found that the action definition here is the same as https://gymnasium.farama.org/environments/atari/ms_pacman/ , action 2 controls the character to move to the right.
I saved the first few frames of observation:

Why is the character moving upwards? Am I missing something? @agarwl @tangbotony @zhixuan-lin @google-admin

I suppose this might be due to using the reduced action space (game dependent) in dopamine rather than full action space (18 actions) .

In fact, in gymnasium Discrete(9), the action corresponding to action 2 is Right.

How to konw the actions defined in dopamine?

[hutchinsonian]

I also observed that the character is moving upwards when action 7 is executed at frames 30-32. I can't match these observations with the actions. This doesn't seem to fit any setting.

[hutchinsonian]

I found that these actions seem to be normal in the breakout environment. This also makes me wonder if there is some difference in the ms-pacman data?

I suppose this might be due to using the reduced action space (game dependent) in dopamine rather than full action space (18 actions) .

The action you mentioned

'MsPacman': [
    'NOOP', 'UP', 'RIGHT', 'LEFT', 'DOWN', 'UPRIGHT', 'UPLEFT', 'DOWNRIGHT',
    'DOWNLEFT'
],

is the same as defined here https://gymnasium.farama.org/environments/atari/ms_pacman/. In MsPacman, action2 is RIGHT. So it does not correspond to observation

[agarwl]

Could it be one-based indexing? There's no reason for MsPacMan to be wrong specifically.
