+
+**OpenAI Gym is a toolkit for developing and comparing reinforcement learning algorithms.** This is the ``gym`` open-source library, which gives you access to an ever-growing variety of environments.
+
+``gym`` makes no assumptions about the structure of your agent, and is compatible with any numerical computation library, such as TensorFlow or Theano. You can use it from Python code, and soon from other languages.
+
+If you're not sure where to start, we recommend beginning with the
+`docs `_ on our site.
+
+A whitepaper for OpenAI Gym is available at http://arxiv.org/abs/1606.01540, and here's a BibTeX entry that you can use to cite it in a publication::
+
+ @misc{1606.01540,
+ Author = {Greg Brockman and Vicki Cheung and Ludwig Pettersson and Jonas Schneider and John Schulman and Jie Tang and Wojciech Zaremba},
+ Title = {OpenAI Gym},
+ Year = {2016},
+ Eprint = {arXiv:1606.01540},
+ }
+
+.. contents:: **Contents of this document**
+ :depth: 2
+
+Basics
+======
+
+There are two basic concepts in reinforcement learning: the
+environment (namely, the outside world) and the agent (namely, the
+algorithm you are writing). The agent sends `actions` to the
+environment, and the environment replies with `observations` and
+`rewards` (that is, a score).
+
+The core `gym` interface is `Env
+`_, which is
+the unified environment interface. There is no interface for agents;
+that part is left to you. The following are the ``Env`` methods you
+should know:
+
+- `reset(self)`: Reset the environment's state. Returns `observation`.
+- `step(self, action)`: Step the environment by one timestep. Returns `observation`, `reward`, `done`, `info`.
+- `render(self, mode='human', close=False)`: Render one frame of the environment. The default mode will do something human friendly, such as pop up a window. Passing the `close` flag signals the renderer to close any such windows.
+
+Installation
+============
+
+You can perform a minimal install of ``gym`` with:
+
+.. code:: shell
+
+ git clone https://github.com/openai/gym.git
+ cd gym
+ pip install -e .
+
+If you prefer, you can do a minimal install of the packaged version directly from PyPI:
+
+.. code:: shell
+
+ pip install gym
+
+You'll be able to run a few environments right away:
+
+- `algorithmic `_
+- `toy_text `_
+- `classic_control `_ (you'll need ``pyglet`` to render though)
+
+We recommend playing with those environments at first, and then later
+installing the dependencies for the remaining environments.
+
+Installing everything
+---------------------
+
+To install the full set of environments, you'll need to have some system
+packages installed. We'll build out the list here over time; please let us know
+what you end up installing on your platform.
+
+On OSX:
+
+.. code:: shell
+
+ brew install cmake boost boost-python sdl2 swig wget
+
+On Ubuntu 14.04:
+
+.. code:: shell
+
+ apt-get install -y python-numpy python-dev cmake zlib1g-dev libjpeg-dev xvfb libav-tools xorg-dev python-opengl libboost-all-dev libsdl2-dev swig
+
+MuJoCo has a proprietary dependency we can't set up for you. Follow
+the
+`instructions `_
+in the ``mujoco-py`` package for help.
+
+Once you're ready to install everything, run ``pip install -e '.[all]'`` (or ``pip install 'gym[all]'``).
+
+Supported systems
+-----------------
+
+We currently support Linux and OS X running Python 2.7 or 3.5.
+Python 3 support should still be considered experimental -- if you find any bugs, please report them!
+
+In particular on OSX + Python3 you may need to run
+
+.. code:: shell
+
+ brew install boost-python --with-python3
+
+We will expand support to Windows based on demand. We
+will also soon ship a Docker container exposing the environments
+callable from any platform, for use with any non-Python framework, such as Torch.
+
+Pip version
+-----------
+
+To run ``pip install -e '.[all]'``, you'll need a semi-recent pip.
+Please make sure your pip is at least at version ``1.5.0``. You can
+upgrade using the following: ``pip install --ignore-installed
+pip``. Alternatively, you can open `setup.py
+`_ and
+install the dependencies by hand.
+
+Rendering on a server
+---------------------
+
+If you're trying to render video on a server, you'll need to connect a
+fake display. The easiest way to do this is by running under
+``xvfb-run`` (on Ubuntu, install the ``xvfb`` package):
+
+.. code:: shell
+
+ xvfb-run -s "-screen 0 1400x900x24" bash
+
+Installing dependencies for specific environments
+-------------------------------------------------
+
+If you'd like to install the dependencies for only specific
+environments, see `setup.py
+`_. We
+maintain the lists of dependencies on a per-environment group basis.
+
+Environments
+============
+
+The code for each environment group is housed in its own subdirectory
+`gym/envs
+`_. The
+specification of each task is in `gym/envs/__init__.py
+`_. It's
+worth browsing through both.
+
+Algorithmic
+-----------
+
+These are a variety of algorithmic tasks, such as learning to copy a
+sequence.
+
+.. code:: python
+
+ import gym
+ env = gym.make('Copy-v0')
+ env.reset()
+ env.render()
+
+Atari
+-----
+
+The Atari environments are a variety of Atari video games. If you didn't do the full install, you can install dependencies via ``pip install -e '.[atari]'`` (you'll need ``cmake`` installed) and then get started as follow:
+
+.. code:: python
+
+ import gym
+ env = gym.make('SpaceInvaders-v0')
+ env.reset()
+ env.render()
+
+This will install ``atari-py``, which automatically compiles the `Arcade Learning Environment `_. This can take quite a while (a few minutes on a decent laptop), so just be prepared.
+
+Board games
+-----------
+
+The board game environments are a variety of board games. If you didn't do the full install, you can install dependencies via ``pip install -e '.[board_game]'`` (you'll need ``cmake`` installed) and then get started as follow:
+
+.. code:: python
+
+ import gym
+ env = gym.make('Go9x9-v0')
+ env.reset()
+ env.render()
+
+Box2d
+-----------
+
+Box2d is a 2D physics engine. You can install it via ``pip install -e '.[box2d]'`` and then get started as follow:
+
+.. code:: python
+
+ import gym
+ env = gym.make('LunarLander-v2')
+ env.reset()
+ env.render()
+
+Classic control
+---------------
+
+These are a variety of classic control tasks, which would appear in a typical reinforcement learning textbook. If you didn't do the full install, you will need to run ``pip install -e '.[classic_control]'`` to enable rendering. You can get started with them via:
+
+.. code:: python
+
+ import gym
+ env = gym.make('CartPole-v0')
+ env.reset()
+ env.render()
+
+Doom
+---------------
+
+These tasks take place inside a Doom game (via the VizDoom project). If you didn't do the full install, you will need to run ``pip install -e '.[doom]'``. You can get started with them via:
+
+.. code:: python
+
+ import gym
+ env = gym.make('DoomBasic-v0')
+ env.reset()
+ env.render()
+
+MuJoCo
+------
+
+`MuJoCo `_ is a physics engine which can do
+very detailed efficient simulations with contacts. It's not
+open-source, so you'll have to follow the instructions in `mujoco-py
+`_
+to set it up. You'll have to also run ``pip install -e '.[mujoco]'`` if you didn't do the full install.
+
+.. code:: python
+
+ import gym
+ env = gym.make('Humanoid-v0')
+ env.reset()
+ env.render()
+
+Toy text
+--------
+
+Toy environments which are text-based. There's no extra dependency to install, so to get started, you can just do:
+
+.. code:: python
+
+ import gym
+ env = gym.make('FrozenLake-v0')
+ env.reset()
+ env.render()
+
+Examples
+========
+
+See the ``examples`` directory.
+
+- Run `examples/agents/random_agent.py `_ to run an simple random agent and upload the results to the scoreboard.
+- Run `examples/agents/cem.py `_ to run an actual learning agent (using the cross-entropy method) and upload the results to the scoreboard.
+- Run `examples/scripts/list_envs `_ to generate a list of all environments. (You see also just `browse `_ the list on our site.
+ - Run `examples/scripts/upload `_ to upload the recorded output from ``random_agent.py`` or ``cem.py``. Make sure to obtain an `API key `_.
+
+Testing
+=======
+
+We are using `nose2 `_ for tests. You can run them via:
+
+.. code:: shell
+
+ nose2
+
+You can also run tests in a specific directory by using the ``-s`` option, or by passing in the specific name of the test. See the `nose2 docs `_ for more details.
+
+What's new
+----------
+
+- 2016-05-28: For controlled reproducibility, envs now support seeding
+ (cf #91 and #135). The monitor records which seeds are used. We will
+ soon add seed information to the display on the scoreboard.

+# Agents
+
+An "agent" describes the method of running an RL algorithm against an environment in the gym. The agent may contain the algorithm itself or simply provide an integration between an algorithm and the gym environments. Submit another to this list via a pull-request.
+
+_**NOTICE**: Evaluations submitted to the scoreboard are encouraged to link a writeup (gist) about duplicating the results. These writeups will likely direct you to specific algorithms. This agent listing is not attempting to replace writeups and will likely in time be filled with general purpose agents that will serve as a great starting place for those looking for tooling integrations or general algorithm ideas and attempts._
+
+## RandomAgent
+
+A sample agent located in this repo at `gym/examples/agents/random_agent.py`. This simple agent leverages the environments ability to produce a random valid action and does so for each step.

+#Table of Contents
+
+ - [Agents](agents.md) contains a listing of agents compatible with gym environments. Agents facilitate the running of an algorithm against an environment.
+
+ - [Environments](environments.md) lists more environments to run your algorithms against. These do not come prepackaged with the gym.
+
+ - [Miscellaneous](misc.md) is a collection of other value-add tools and utilities. These could be anything from a small convenience lib to a collection of video tutorials or a new language binding.

+# Envs
+
+These are the core integrated environments. Note that we may later
+restructure any of the files, but will keep the environments available
+at the relevant package's top-level. So for example, you should access
+`AntEnv` as follows:
+
+```
+# Will be supported in future releases
+from gym.envs import mujoco
+mujoco.AntEnv
+```
+
+Rather than:
+
+```
+# May break in future releases
+from gym.envs.mujoco import ant
+ant.AntEnv
+```
+
+## How to add new environments to Gym
+
+1. Write your environment in an existing collection or a new collection. All collections are subfolders of `/gym/envs'.
+2. Import your environment into the `__init__.py` file of the collection. This file will be located at `/gym/envs/my_collection/__init__.py`. Add `from gym.envs.my_collection.my_awesome_env import MyEnv` to this file.
+3. Register your env in `/gym/envs/__init__.py`:
+
+ ```
+register(
+ id='MyEnv-v0',
+ entry_point='gym.envs.my_collection:MyEnv',
+)
+```
+
+4. Add your environment to the scoreboard in `/gym/scoreboard/__init__.py`:
+
+ ```
+add_task(
+ id='MyEnv-v0',
+ summary="Super cool environment",
+ group='my_collection',
+ contributor='mygithubhandle',
+)
+```

+# This is simple 4-joints walker robot environment.
+#
+# There are two versions:
+#
+# - Normal, with slightly uneven terrain.
+#
+# - Hardcore with ladders, stumps, pitfalls.
+#
+# Reward is given for moving forward, total 300+ points up to the far end. If the robot falls,
+# it gets -100. Applying motor torque costs a small amount of points, more optimal agent
+# will get better score.
+#
+# Heuristic is provided for testing, it's also useful to get demonstrations to
+# learn from. To run heuristic:
+#
+# python gym/envs/box2d/bipedal_walker.py
+#
+# State consists of hull angle speed, angular velocity, horizontal speed, vertical speed,
+# position of joints and joints angular speed, legs contact with ground, and 10 lidar
+# rangefinder measurements to help to deal with the hardcore version. There's no coordinates
+# in the state vector. Lidar is less useful in normal version, but it works.
+#
+# To solve the game you need to get 300 points in 1600 time steps.
+#
+# To solve hardcore version you need 300 points in 2000 time steps.

+# Rocket trajectory optimization is a classic topic in Optimal Control.

+# According to Pontryagin's maximum principle it's optimal to fire engine full throttle or
+# turn it off. That's the reason this environment is OK to have discreet actions (engine on or off).
+#
+# Landing pad is always at coordinates (0,0). Coordinates are the first two numbers in state vector.
+# Reward for moving from the top of the screen to landing pad and zero speed is about 100..140 points.
+# If lander moves away from landing pad it loses reward back. Episode finishes if the lander crashes or
+# comes to rest, receiving additional -100 or +100 points. Each leg ground contact is +10. Firing main
+# engine is -0.3 points each frame. Solved is 200 points.
+#
+# Landing outside landing pad is possible. Fuel is infinite, so an agent can learn to fly and then land
+# on its first attempt. Please see source code for details.

+ Acrobot is a 2-link pendulum with only the second joint actuated
+ Intitially, both links point downwards. The goal is to swing the
+ end-effector at a height at least the length of one link above the base.
+ Both links can swing freely and can pass by each other, i.e., they don't
+ collide when they have the same angle.
+ **STATE:**
+ The state consists of the two rotational joint angles and their velocities
+ [theta1 theta2 thetaDot1 thetaDot2]. An angle of 0 corresponds to corresponds
+ to the respective link pointing downwards (angles are in world coordinates).
+ **ACTIONS:**
+ The action is either applying +1, 0 or -1 torque on the joint between
+ the two pendulum links.
+ .. note::
+ The dynamics equations were missing some terms in the NIPS paper which
+ are present in the book. R. Sutton confirmed in personal correspondance
+ that the experimental results shown in the paper and the book were
+ generated with the equations shown in the book.
+ However, there is the option to run the domain with the paper equations
+ by setting book_or_nips = 'nips'
+ **REFERENCE:**
+ .. seealso::
+ R. Sutton: Generalization in Reinforcement Learning:
+ Successful Examples Using Sparse Coarse Coding (NIPS 1996)
+ .. seealso::
+ R. Sutton and A. G. Barto:
+ Reinforcement learning: An introduction.
+ Cambridge: MIT press, 1998.
+ .. warning::
+ This version of the domain uses the Runge-Kutta method for integrating
+ the system dynamics and is more realistic, but also considerably harder
+ than the original version which employs Euler integration,
+ see the AcrobotLegacy class.

+###Controls
+
+Doom is usually played with a full keyboard, and multiple keys can be pressed at once.
+
+To replicate this, we broke down the possible actions in 43 keys. Each key can be pressed (value of 1), or unpressed (value of 0).
+
+The last 5 commands are deltas. [38] - LOOK_UP_DOWN_DELTA and [39] - TURN_LEFT_RIGHT_DELTA replicate mouse movement where values are in the
+range -10 to +10. They represent mouse movement over the x and y axis. (e.g. +5 for LOOK_UP_DOWN_DELTA will make the player look up 5 degrees)
+
+[40] - MOVE_FORWARD_BACKWARD_DELTA, [41] - MOVE_LEFT_RIGHT_DELTA, and [42] - MOVE_UP_DOWN_DELTA represent the speed on an axis.
+Their values range from -100 to 100, where +100 is the maximum speed in one direction, and -100 is the maximum speed in the other.
+(e.g. MOVE_FORWARD_BACKWARD_DELTA of +100 will make the player move forward at 100% of max speed, and -100 will make the player
+move backward at 100% of max speed).
+
+A list of values is expected to be passed as the action (e.g. [0, 1, 0, 0, 1, 0, .... ]).
+
+Each mission is restricted on what actions can be performed, but the mapping is the same across all missions.
+
+For example, if we want to [0] - ATTACK, [2] - JUMP, and [13] - MOVE_FORWARD at the same time, we would submit the following action:
+
+```python
+action = [0] * 43
+action[0] = 1
+action[2] = 1
+action[13] = 1
+```
+
+The full list of possible actions is:
+
+* [0] - ATTACK - Shoot weapon - Values 0 or 1
+* [1] - USE - Use item - Values 0 or 1
+* [2] - JUMP - Jump - Values 0 or 1
+* [3] - CROUCH - Crouch - Values 0 or 1
+* [4] - TURN180 - Perform 180 turn - Values 0 or 1
+* [5] - ALT_ATTACK - Perform alternate attack
+* [6] - RELOAD - Reload weapon - Values 0 or 1
+* [7] - ZOOM - Toggle zoom in/out - Values 0 or 1
+* [8] - SPEED - Run faster - Values 0 or 1
+* [9] - STRAFE - Strafe (moving sideways in a circle) - Values 0 or 1
+* [10] - MOVE_RIGHT - Move to the right - Values 0 or 1
+* [11] - MOVE_LEFT - Move to the left - Values 0 or 1
+* [12] - MOVE_BACKWARD - Move backward - Values 0 or 1
+* [13] - MOVE_FORWARD - Move forward - Values 0 or 1
+* [14] - TURN_RIGHT - Turn right - Values 0 or 1
+* [15] - TURN_LEFT - Turn left - Values 0 or 1
+* [16] - LOOK_UP - Look up - Values 0 or 1
+* [17] - LOOK_DOWN - Look down - Values 0 or 1
+* [18] - MOVE_UP - Move up - Values 0 or 1
+* [19] - MOVE_DOWN - Move down - Values 0 or 1
+* [20] - LAND - Land (e.g. drop from ladder) - Values 0 or 1
+* [21] - SELECT_WEAPON1 - Select weapon 1 - Values 0 or 1
+* [22] - SELECT_WEAPON2 - Select weapon 2 - Values 0 or 1
+* [23] - SELECT_WEAPON3 - Select weapon 3 - Values 0 or 1
+* [24] - SELECT_WEAPON4 - Select weapon 4 - Values 0 or 1
+* [25] - SELECT_WEAPON5 - Select weapon 5 - Values 0 or 1
+* [26] - SELECT_WEAPON6 - Select weapon 6 - Values 0 or 1
+* [27] - SELECT_WEAPON7 - Select weapon 7 - Values 0 or 1
+* [28] - SELECT_WEAPON8 - Select weapon 8 - Values 0 or 1
+* [29] - SELECT_WEAPON9 - Select weapon 9 - Values 0 or 1
+* [30] - SELECT_WEAPON0 - Select weapon 0 - Values 0 or 1
+* [31] - SELECT_NEXT_WEAPON - Select next weapon - Values 0 or 1
+* [32] - SELECT_PREV_WEAPON - Select previous weapon - Values 0 or 1
+* [33] - DROP_SELECTED_WEAPON - Drop selected weapon - Values 0 or 1
+* [34] - ACTIVATE_SELECTED_WEAPON - Activate selected weapon - Values 0 or 1
+* [35] - SELECT_NEXT_ITEM - Select next item - Values 0 or 1
+* [36] - SELECT_PREV_ITEM - Select previous item - Values 0 or 1
+* [37] - DROP_SELECTED_ITEM - Drop selected item - Values 0 or 1
+* [38] - LOOK_UP_DOWN_DELTA - Look Up/Down - Range of -10 to 10 (integer).
+ - Value is the angle - +5 will look up 5 degrees, -5 will look down 5 degrees
+* [39] - TURN_LEFT_RIGHT_DELTA - Turn Left/Right - Range of -10 to 10 (integer).
+ - Value is the angle - +5 will turn right 5 degrees, -5 will turn left 5 degrees
+* [40] - MOVE_FORWARD_BACKWARD_DELTA - Speed of forward/backward movement - Range -100 to 100 (integer).

+------------ Meta - Doom ------------
+This is a meta map that combines all 9 Doom levels.
+
+Levels:
+
+ 0 - Doom Basic
+ 1 - Doom Corridor
+ 2 - Doom DefendCenter
+ 3 - Doom DefendLine
+ 4 - Doom HealthGathering
+ 5 - Doom MyWayHome
+ 6 - Doom PredictPosition
+ 7 - Doom TakeCover
+ 8 - Doom Deathmatch
+
+Goal: 9,000 points
+ - Pass all levels
+
+Scoring:
+ - Each level score has been standardized on a scale of 0 to 1,000
+ - The passing score for a level is 990 (99th percentile)
+ - A bonus of 450 (50 * 9 levels) is given if all levels are passed
+ - The score for a level is the average of the last 3 tries
+ - If there has been less than 3 tries for a level, the missing tries will have a score of 0
+ (e.g. if you score 1,000 on the first level on your first try, your level score will be (1,000+0+0)/ 3 = 333.33)
+ - The total score is the sum of the level scores, plus the bonus if you passed all levels.
+
+ e.g. List of tries:
+
+ - Level 0: 500
+ - Level 0: 750
+ - Level 0: 800
+ - Level 0: 1,000
+ - Level 1: 100
+ - Level 1: 200
+
+ Level score for level 0 = [1,000 + 800 + 750] / 3 = 850 (Average of last 3 tries)
+ Level score for level 1 = [200 + 100 + 0] / 3 = 100 (Tries not completed have a score of 0)
+ Level score for levels 2 to 8 = 0
+ Bonus score for passing all levels = 0
+ ------------------------
+ Total score = 850 + 100 + 0 + 0 = 950
+
+Changing Level:
+ - To unlock the next level, you must achieve a level score (avg of last 3 tries) of at least 600
+ (i.e. passing 60% of the last level)
+ - There are 2 ways to change level:
+
+ 1) Manual method
+
+ - obs, reward, is_finished, info = env.step(action)
+ - if is_finished is true, you can call env.change_level(level_number) to change to an unlocked level
+ - you can see
+ the current level with info["LEVEL"]
+ the list of level score with info["SCORES"],
+ the list of locked levels with info["LOCKED_LEVELS"]
+ your total score with info["TOTAL_REWARD"]
+
+ e.g.
+ import gym
+ env = gym.make('meta-Doom-v0')
+ env.reset()
+ total_score = 0
+ while total_score < 9000:
+ action = [0] * 43
+ obs, reward, is_finished, info = env.step(action)
+ env.render()
+ total_score = info["TOTAL_REWARD"]
+ if is_finished:
+ env.change_level(level_you_want)
+
+ 2) Automatic change
+
+ - if you don't call change_level() and the level is finished, the system will automatically select the
+ unlocked level with the lowest level score (which is likely to be the last unlocked level)
+
+ e.g.
+ import gym
+ env = gym.make('meta-Doom-v0')
+ env.reset()
+ total_score = 0
+ while total_score < 9000:
+ action = [0] * 43
+ obs, reward, is_finished, info = env.step(action)
+ env.render()
+ total_score = info["TOTAL_REWARD"]
+
+Allowed actions:
+ - Each level has their own allowed actions, see each level for details
+
+Mode:
+ - env.mode can be 'fast', 'normal' or 'human' (e.g. env.mode = 'fast')
+ - 'fast' (default) will run as fast as possible (~75 fps) (best for simulation)
+ - 'normal' will run at roughly 35 fps (easier for human to watch)
+ - 'human' will let you play the game (keyboard: Arrow Keys, '<', '>' and Ctrl, mouse available for Doom Deathmatch)
+
+ e.g. to start in human mode:
+
+ import gym
+ env = gym.make('meta-Doom-v0')
+ env.mode='human'
+ env.reset()
+ num_episodes = 10
+ for i in range(num_episodes):
+ env.step([0] * 43)
+
+Actions:
+ actions = [0] * 43
+ actions[0] = 0 # ATTACK
+ actions[1] = 0 # USE
+ [...]
+ actions[42] = 0 # MOVE_UP_DOWN_DELTA
+ A full list of possible actions is available in controls.md

+ """Simple blackjack environment
+
+ Blackjack is a card game where the goal is to obtain cards that sum to as
+ near as possible to 21 without going over. They're playing against a fixed
+ dealer.
+ Face cards (Jack, Queen, King) have point value 10.
+ Aces can either count as 11 or 1, and it's called 'usable' at 11.
+ This game is placed with an infinite deck (or with replacement).
+ The game starts with each (player and dealer) having one face up and one
+ face down card.
+
+ The player can request additional cards (hit=1) until they decide to stop
+ (stick=0) or exceed 21 (bust).
+
+ After the player sticks, the dealer reveals their facedown card, and draws
+ until their sum is 17 or greater. If the dealer goes bust the player wins.
+
+ If neither player nor dealer busts, the outcome (win, lose, draw) is
+ decided by whose sum is closer to 21. The reward for winning is +1,
+ drawing is 0, and losing is -1.
+
+ The observation of a 3-tuple of: the players current sum,
+ the dealer's one showing card (1-10 where 1 is ace),
+ and whether or not the player holds a usable ace (0 or 1).
+
+ This environment corresponds to the version of the blackjack problem
+ described in Example 5.1 in Reinforcement Learning: An Introduction
+ by Sutton and Barto (1998).

+# Wrappers (experimental)
+
+This is a placeholder for now: we will likely soon start adding
+standardized wrappers for environments. (Only stable and
+general-purpose wrappers will be accepted into gym core.)
+
+Note that we may later restructure any of the files, but will keep the
+wrappers available at the wrappers' top-level folder. So for
+example, you should access `MyWrapper` as follows:
+
+```
+# Will be supported in future releases
+from gym.wrappers import MyWrapper
+```
+
+## How to add new wrappers to Gym
+
+1. Write your wrapper in the wrappers' top-level folder.
+2. Import your wrapper into the `__init__.py` file. This file is located at `/gym/wrappers/__init__.py`. Add `from gym.wrappers.my_awesome_wrapper import MyWrapper` to this file.
+3. Write a good description of the utility of your wrapper using python docstring format (""" """ under the class definition)
+
+
+## Quick Tips
+
+- Don't forget to call super(class_name, self).__init__(env) if you override the wrapper's __init__ function
+- You can access the inner environment with `self.unwrapped`
+- You can access the previous layer using `self.env`
+- The variables `metadata`, `action_space`, `observation_space`, `reward_range`, and `spec` are copied to `self` from the previous layer
+- Create a wrapped function for at least one of the following: `__init__(self, env)`, `_step`, `_reset`, `_render`, `_close`, `_configure`, or `_seed`
+- Your layered function should take its input from the previous layer (`self.env`) and/or the inner layer (`self.unwrapped`)

+$program:
+
+ A hack to run a stock Xorg(1) or XFree86(1) X server with the "dummy"
+ (RAM-only framebuffer) video driver such that it AVOIDS the Linux VT
+ switching, opening device files in /dev, keyboard and mouse conflicts,
+ and other problems associated with the normal use of "dummy".
+
+ In other words, it tries to make Xorg/XFree86 with the "dummy"
+ device driver act more like Xvfb(1).
+
+ The primary motivation for the Xdummy script is to provide a virtual X
+ server for x11vnc but with more features than Xvfb (or Xvnc); however
+ it could be used for other reasons (e.g. better automated testing
+ than with Xvfb.) One nice thing is the dummy server supports RANDR
+ dynamic resizing while Xvfb does not.
+
+ So, for example, x11vnc+Xdummy terminal services are a little better
+ than x11vnc+Xvfb.
+
+ To achieve this, while running the real Xserver $program intercepts
+ system and library calls via the LD_PRELOAD method and modifies
+ the behavior to make it work correctly (e.g. avoid the VT stuff.)
+ LD_PRELOAD tricks are usually "clever hacks" and so might not work
+ in all situations or break when something changes.
+
+ WARNING: Take care in using Xdummy, although it never has it is
+ possible that it could damage hardware. One can use the -prconf
+ option to have it print out the xorg.conf config that it would use
+ and then inspect it carefully before actually using it.
+
+ This program no longer needs to be run as root as of 12/2009.
+ However, if there are problems for certain situations (usually older
+ servers) it may perform better if run as root (use the -root option.)
+ When running as root remember the previous paragraph and that Xdummy
+ comes without any warranty.
+
+ gcc/cc and other build tools are required for this script to be able
+ to compile the LD_PRELOAD shared object. Be sure they are installed
+ on the system. See -install and -uninstall described below.
+
+ Your Linux distribution may not install the dummy driver by default,
+ e.g:
+
+ /usr/lib/xorg/modules/drivers/dummy_drv.so
+
+ some have it in a package named xserver-xorg-video-dummy you that
+ need to install.
+
+Usage:
+
+ $program <${program}-args>
+
+ (actually, the arguments can be supplied in any order.)
+
+Examples:
+
+ $program -install
+
+ $program :1
+
+ $program -debug :1
+
+ $program -tmpdir ~/mytmp :1 -nolisten tcp
+
+startx example:
+
+ startx -e bash -- $program :2 -depth 16
+
+ (if startx needs to be run as root, you can su(1) to a normal
+ user in the bash shell and then launch ~/.xinitrc or ~/.xsession,
+ gnome-session, startkde, startxfce4, etc.)
+
+xdm example:
+
+ xdm -config /usr/local/dummy/xdm-config -nodaemon
+
+ where the xdm-config file has line:
+
+ DisplayManager.servers: /usr/local/dummy/Xservers
+
+ and /usr/local/dummy/Xservers has lines:
+
+ :1 local /usr/local/dummy/Xdummy :1 -debug
+ :2 local /usr/local/dummy/Xdummy :2 -debug
+
+ (-debug is optional)
+
+gdm/kdm example:
+
+ TBD.
+
+Config file:
+
+ If the file $program.cfg exists it will be sourced as shell
+ commands. Usually one will set some variables this way.
+ To disable sourcing, supply -nocfg or set XDUMMY_NOCFG=1.
+
+Root permission and x11vnc:
+
+ Update: as of 12/2009 this program no longer must be run as root.
+ So try it as non-root before running it as root and/or the
+ following schemes.
+
+ In some circumstances X server program may need to be run as root.

+
+Options:
+
+ ${program}-args:
+
+ -install Compile the LD_PRELOAD shared object and install it
+ next to the $program script file as:
+
+ $0.so
+
+ When that file exists it is used as the LD_PRELOAD
+ shared object without recompiling. Otherwise,
+ each time $program is run the LD_PRELOAD shared
+ object is compiled as a file in /tmp (or -tmpdir)
+
+ If you set the environment variable
+ INTERPOSE_GETUID=1 when building, then when
+ $program is run as an ordinary user, the shared
+ object will interpose getuid() calls and pretend
+ to be root. Otherwise it doesn't pretend to
+ be root.
+
+ You can also set the CFLAGS environment variable
+ to anything else you want on the compile cmdline.
+
+ -uninstall Remove the file:
+
+ $0.so
+
+ The LD_PRELOAD shared object will then be compiled
+ each time this program is run.
+
+ The X server is not started under -install, -uninstall, or -prconf.
+
+
+ :N The DISPLAY (e.g. :15) is often the first
+ argument. It is passed to the real X server and
+ also used by the Xdummy script as an identifier.
+
+ -geom geom1[,geom2...] Take the geometry (e.g. 1024x768) or list
+ of geometries and insert them into the Screen
+ section of the tweaked X server config file.
+ Use this to have a different geometry than the
+ one(s) in the system config file.
+
+ The option -geometry can be used instead of -geom;
+ x11vnc calls Xdummy and Xvfb this way.
+
+ -nomodelines When you specify -geom/-geometry, $program will
+ create Modelines for each geometry and put them
+ in the Monitor section. If you do not want this
+ then supply -nomodelines.
+
+ -depth n Use pixel color depth n (e.g. 8, 16, or 24). This
+ makes sure the X config file has a Screen.Display
+ subsection of this depth. Note this option is
+ ALSO passed to the X server.
+
+ -DEPTH n Same as -depth, except not passed to X server.
+
+ -tmpdir dir Specify a temporary directory, owned by you and
+ only writable by you. This is used in place of
+ /tmp/Xdummy.\$USER/.. to place the $program.so
+ shared object, tweaked config files, etc.
+
+ -nonroot Run in non-root mode (working 12/2009, now default)
+
+ -root Run as root (may still be needed in some
+ environments.) Same as XDUMMY_RUN_AS_ROOT=1.
+
+ -nosudo Do not try to use sudo(1) when re-running as root,
+ use su(1) instead.
+
+ -xserver path Specify the path to the Xserver to use. Default
+ is to try "Xorg" first and then "XFree86". If
+ those are not in \$PATH, it tries these locations:
+ /usr/bin/Xorg
+ /usr/X11R6/bin/Xorg
+ /usr/X11R6/bin/XFree86
+
+ -n Do not run the command to start the X server,
+ just show the command that $program would run.
+ The LD_PRELOAD shared object will be built,
+ if needed. Also note any XDUMMY* environment
+ variables that need to be set.
+
+ -prconf Print, to stdout, the tweaked Xorg/XFree86
+ config file (-config and -xf86config server
+ options, respectively.) The Xserver is not
+ started.
+
+ -notweak Do not tweak (modify) the Xorg/XFree86 config file
+ (system or server command line) at all. The -geom
+ and similar config file modifications are ignored.
+
+ It is up to you to make sure it is a working
+ config file (e.g. "dummy" driver, etc.)
+ Perhaps you want to use a file based on the
+ -prconf output.
+
+ -nocfg Do not try to source $program.cfg even if it
+ exists. Same as setting XDUMMY_NOCFG=1.
+
+ -debug Extra debugging output.
+
+ -strace strace(1) the Xserver process (for troubleshooting.)
+ -ltrace ltrace(1) instead of strace (can be slow.)
+
+ -h, -help Print out this help.
+
+
+ Xserver-args:
+
+ Most of the Xorg and XFree86 options will work and are simply
+ passed along if you supply them. Important ones that may be
+ supplied if missing:
+
+ :N X Display number for server to use.
+
+ vtNN Linux virtual terminal (VT) to use (a VT is currently
+ still used, just not switched to and from.)
+
+ -config file Driver "dummy" tweaked config file, a
+ -xf86config file number of settings are tweaked besides Driver.
+
+ If -config/-xf86config is not given, the system one
+ (e.g. /etc/X11/xorg.conf) is used. If the system one cannot be
+ found, a built-in one is used. Any settings in the config file
+ that are not consistent with "dummy" mode will be overwritten
+ (unless -notweak is specified.)
+
+ Use -config xdummy-builtin to force usage of the builtin config.
+
+ If "file" is only a basename (e.g. "xorg.dummy.conf") with no /'s,
+ then no tweaking of it is done: the X server will look for that
+ basename via its normal search algorithm. If the found file does
+ not refer to the "dummy" driver, etc, then the X server will fail.
+
+ You can set the env. var. XDUMMY_EXTRA_SERVER_ARGS to hold some
+ extra Xserver-args too. (Useful for cfg file.)
+
+Notes:
+
+ The Xorg/XFree86 "dummy" driver is currently undocumented. It works
+ well in this mode, but it is evidently not intended for end-users.
+ So it could be removed or broken at any time.
+
+ If the display Xserver-arg (e.g. :1) is not given, or ":" is given
+ that indicates $program should try to find a free one (based on
+ tcp ports.)
+
+ If the display virtual terminal, VT, (e.g. vt9) is not given that
+ indicates $program should try to find a free one (or guess a high one.)
+
+ This program is not completely secure WRT files in /tmp (but it tries
+ to a good degree.) Better is to use the -tmpdir option to supply a
+ directory only writable by you. Even better is to get rid of users
+ on the local machine you do not trust :-)
+
+ Set XDUMMY_SET_XV=1 to turn on debugging output for this script.
