Added an additional parameter for including alignment in blstats

[samvelyan]

Added an additional parameter to MiniHack environments for including alignment flag in blstats.

This is to ensure that models trained on earlier MiniHack versions can be executed following NLE 0.9.0 update.

Example usage

>>> import gym, minihack
>>> env = gym.make("MiniHack-River-v0", include_alignment_blstats=True)
>>> o = env.reset()
>>> len(o['blstats'])
27
>>> o['blstats']
array([38, 13, 16, 16, 16, 12, 15,  8,  8,  0, 12, 12,  1,  0,  2,  2,  7,
        0,  1,  0,  1,  1,  0,  0,  1,  0, -1])
>>> env.close()
>>> env = gym.make("MiniHack-River-v0", include_alignment_blstats=False)
>>> o = env.reset()
>>> len(o['blstats'])
26
>>> o['blstats']
array([32, 10, 10, 10, 18, 14, 12, 10, 11,  0, 12, 12,  1,  0,  2,  2,  7,
        0,  1,  0,  1,  1,  0,  0,  1,  0])

This looks convenient now @samvelyan. Thank you.

Hey @samvelyan ! Looks like include_alignment_blstats flag is not reflected in env.observation_space. Please see the following example -

>>> import minihack
>>> import gym
>>> env = gym.make("MiniHack-MultiRoom-N6-v0", include_alignment_blstats=False)
>>> env.observation_space
Dict(blstats:Box(27,), chars:Box(21, 79), chars_crop:Box(9, 9), colors:Box(21, 79), colors_crop:Box(9, 9), glyphs:Box(21, 79), glyphs_crop:Box(9, 9), message:Box(256,), specials:Box(21, 79), specials_crop:Box(9, 9))
>>> env = gym.make("MiniHack-MultiRoom-N6-v0", include_alignment_blstats=True)
>>> env.observation_space
Dict(blstats:Box(27,), chars:Box(21, 79), chars_crop:Box(9, 9), colors:Box(21, 79), colors_crop:Box(9, 9), glyphs:Box(21, 79), glyphs_crop:Box(9, 9), message:Box(256,), specials:Box(21, 79), specials_crop:Box(9, 9))

Thanks @SharathRaparthy for pointing this out. #85 resolves this.

Great! Thanks @samvelyan
