Adding return_info argument to reset to allow for optional info dict as a second return value (#2546) * initial draft of optional info dict in reset function, implemented for cartpole, tests seem to be passing * merged core.py * updated return type annotation for reset function in core.py * optional metadata with return_info from reset added for all first party environments, with corresponding tests. Incomplete implementation for wrappers and vector wrappers * removed Optional type for return_info arguments * added tests for return_info to normalize wrapper and sync_vector_env * autoformatted using black * added optional reset metadata tests to several wrappers * added return_info capability to async_vector_env.py and test to verify functionality * added optional return_info test for record_video.py * removed tests for mujoco environments * autoformatted * improved test coverage for optional reset return_info * re-removed unit test envs accidentally reintroduced in merge * removed unnecessary import * changes based on code-review * small fix to core wrapper typing and autoformatted record_epsisode_stats * small change to pass flake8 style 2022-02-06 17:28:27 -06:00			`import numpy as np`
Improve `pre-commit` workflow (#2602) * feat: add `isort` to `pre-commit` * ci: skip `__init__.py` file for `isort` * ci: make `isort` mandatory in lint pipeline * docs: add a section on Git hooks * ci: check isort diff * fix: isort from master branch * docs: add pre-commit badge * ci: update black + bandit versions * feat: add PR template * refactor: PR template * ci: remove bandit * docs: add Black badge * ci: try to remove all `\|\| true` statements * ci: remove lint_python job - Remove `lint_python` CI job - Move `pyupgrade` job to `pre-commit` workflow * fix: avoid messing with typing * docs: add a note on running `pre-cpmmit` manually * ci: apply `pre-commit` to the whole codebase 2022-03-31 12:50:38 -07:00			`import pytest`
