I got error

[rubashka]

player_y, player_x = (obs.observation["minimap"][_PLAYER_RELATIVE] == _PLAYER_SELF).nonzero()

KeyError: 'minimap'

Why does it happen and how can I fix it...?

Looks like there may be some breaking changes from a newer release of pysc2? In the "Refining the Sparse Reward Agent": From the command line I got an error that "T" is not a valid race type. Changing that to "terran" allowed the simulation to launch, but it soon crashed with a "key not found" error:

File "skjb\pysc2-tutorial\Refining the Sparse Reward Agent\refined_agent.py", line 173, in step
unit_type = obs.observation['screen'][_UNIT_TYPE]
KeyError: 'screen'

Very late solution post, but will be useful for other people hopefully,

IF YOU ARE USING pysc2 version 3.0.0

1. Instead of obs.observation['screen'][_UNIT_TYPE] use
   obs.observation["feature_screen"][_UNIT_TYPE]

2. Instead of obs.observation["minimap"][_PLAYER_RELATIVE] use
   obs.observation["feature_screen"][_PLAYER_RELATIVE]
