```
np.uint8(0).dtype.kind in np.typecodes['AllInteger'] == False
np.uint8(0).dtype.char in np.typecodes['AllInteger'] == True
```
```
dtype.kind A character code (one of ‘biufcmMOSUV’) identifying the general kind of data.
dtype.char A unique character code for each of the 21 different built-in types.
```
`contains` really should not exist when it does exactly what the builtin
magic method `__contains__` was meant for, but that would break backward
compatibility.
* add dtype to Box
* remove board_game, debugging, safety, parameter_tuning environments
* massive set of breaking changes
- remove python logging module
- _step, _reset, _seed, _close => non underscored method
- remove benchmark and scoring folder
* Improve render("human"), now resizable, closable window.
* get rid of default step and reset in wrappers, so it doesn’t silently fail for people with underscore methods
* CubeCrash unit test environment
* followup fixes
* MemorizeDigits unit test envrionment
* refactored spaces a bit
fixed indentation
disabled test_env_semantics
* fix unit tests
* fixes
* CubeCrash, MemorizeDigits tested
* gym backwards compatibility patch
* gym backwards compatibility, followup fixes
* changelist, add spaces to main namespaces
* undo_logger_setup for backwards compat
* remove configuration.py
* Doom - Added reward_threshold and timestep_limit for all environments
* Doom - Returning all available game variables
* Doom - Moved _seed to doom_env to avoid repetition in every environment
* Doom - Added ALT_ATTACK and made all action_space equivalent (same controls between environments).
* Doom - Actions can either be a short list of allowed actions or the full list of 41 commands
* Doom - Returning black observation space on error or is_finished, rather than empty list (which was triggering an error)
* Doom - HighLow.sample() returns the small list.
* Doom - Updated difficulty for some missions
* Doom - Fixed inconsistency between controls.md and deathmatch.cfg
* Doom - Issue #168 - Remove sleep statement from DoomEnv render
* Doom - Only using full action space (43 keys)
- Added 'normal', 'fast' and 'human' mode
- Set non-deterministic to True
- Set video.frames_per_second to 35
- Properly returning game variables
* Replaced warnings.warn by logger.warn
* Doom - Added NUM_ACTIONS and action_idx instead of x
* Doom - Added NUM_ACTIONS and action_idx instead of x
* Doom - reset() only calls game.new_episode() after first call
* Doom is now deterministic
* Doom - Partial fix for issue #167 - DoomDeathmatch environment crashes sporadically
* Doom - Standardized envs, simplified _reset
* Doom - Removed temporary fix for issue #167
* Doom - Added scoreboard summary and description
* Make environments seedable
* Fix monitor bugs
- Set monitor_id before setting the infix. This was a bug that would yield incorrect results with multiple monitors.
- Remove extra pid from stats recorder filename. This should be purely cosmetic.
* Start uploading seeds in episode_batch
* Fix _bigint_from_bytes for python3
* Set seed explicitly in random_agent
* Pass through seed argument
* Also pass through random state to spaces
* Pass random state into the observation/action spaces
* Make all _seed methods return the list of used seeds
* Switch over to np.random where possible
* Start hashing seeds, and also seed doom engine
* Fixup seeding determinism in many cases
* Seed before loading the ROM
* Make seeding more Python3 friendly
* Make the MuJoCo skipping a bit more forgiving
* Remove debugging PDB calls
* Make setInt argument into raw bytes
* Validate and upload seeds
* Skip box2d
* Make seeds smaller, and change representation of seeds in upload
* Handle long seeds
* Fix RandomAgent example to be deterministic
* Handle integer types correctly in Python2 and Python3
* Try caching pip
* Try adding swap
* Add df and free calls
* Bump swap
* Bump swap size
* Try setting overcommit
* Try other sysctls
* Try fixing overcommit
* Try just setting overcommit_memory=1
* Add explanatory comment
* Add what's new section to readme
* BUG: Mark ElevatorAction-ram-v0 as non-deterministic for now
* Document seed
* Move nondetermistic check into spec
