Data for expert gameplay

[Roger Creus]

Hi!

In the paper, you mention:

For perspective, it took one of the authors (with extensive knowledge of the game mechanics) roughly 5 hours of gameplay to first achieve a ‘perfect’ run where every achievement was completed. This was playing in a GUI that allowed for unlimited time to pause and think before taking each action.

And I see the play_craftax() function records the trajectories of environment states, actions and rewards. Could you please release that data for the "perfect run" you mention in the paper?

Thank you! :)

Hi Roger, releasing a small offline dataset is on my TODO list - I'll let you know when it's released

@roger-creus please see the new offline dataset section in the README. Unfortunately the subsequent refactors of the environment have made the pkl files invalid, but you can role back to v1.1.0 and it should all work.

Let me know if that works for you!

Hey! Re-opening this @MichaelTMatthews ! I have been able to call render_craftax_pixels but not render_craftax_text on all states in the dataset! I am using craftax==1.1.0 as suggested for processing this data.

When rendering the text observations I get:

Traceback (most recent call last):
  text_obs = render_craftax_text(state)
  craftax/renderer.py", line 1062, in render_craftax_text
    text_obs += ItemType(item_map_view[x, y]).name.lower() + " on "
ValueError: Array(7, dtype=int32) is not a valid ItemType

The ItemType=7 does not seem to exist either in v1.1.0 or the current one. How can I proceed? Thank you! :)
