Universe: a software platform for measuring and training an AI's general intelligence across the world's supply of games, websites and other applications.
As is, universe.vectorized.MultiprocessingEnv has two bugs:
In gym versions at or before 0.7.4, a core.Env has a flag self._configured, usually set by configure(), but not set by the configure() method overridden by MultiprocessingEnv. This causes configure() to be re-called with empty arguments upon reset.
seed_n does not seed individual workers, it instead re-uses the same first seed among all worker environments.
This PR adds a single test which checks for both issues and fixes the bugs.
