<p>ALE-py doesn’t include the atari ROMs (<code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">gymnasium[atari]</span></code>) which are necessary to make any of the atari environments.
|

To install the atari ROM, use <code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">gymnasium[accept-rom-license]</span></code> which will install AutoROM and download the ROMs, install them in the default location.

In doing so, you agree to TODO</p>
|

<p>It is possible to install the ROMs in an alternative location, <a class="reference external" href="https://github.com/Farama-Foundation/AutoROM">repo</a> has more information.</p>

<p>If you use v0 or v4 and the environment is initialized via <code class="docutils literal notranslate"><span class="pre">make</span></code>, the action space will usually be much smaller since most legal actions don’t have
|
||
any effect. Thus, the enumeration of the actions will differ. The action space can be expanded to the full
|
||
legal space by passing the keyword argument <code class="docutils literal notranslate"><span class="pre">full_action_space=True</span></code> to <code class="docutils literal notranslate"><span class="pre">make</span></code>.</p>
|
||
<p>The reduced action space of an Atari environment may depend on the “flavor” of the game. You can specify the flavor by providing
|
||
the arguments <code class="docutils literal notranslate"><span class="pre">difficulty</span></code> and <code class="docutils literal notranslate"><span class="pre">mode</span></code> when constructing the environment. This documentation only provides details on the

action spaces of default flavor choices.</p>

<h2>Stochasticity<a class="headerlink" href="#stochasticity" title="Permalink to this heading">#</a></h2>
|
||
<p>It was pointed out in <a class="reference internal" href="#id1"><span class="std std-ref">[1]</span></a> that Atari games are entirely deterministic. Thus, agents could achieve
|
||
state-of-the-art performance by simply memorizing an optimal sequence of actions while completely ignoring observations from the environment.
|
||
To avoid this, ALE implements sticky actions: Instead of always simulating the action passed to the environment, there is a small
|
||
probability that the previously executed action is used instead.</p>
|
||
<p>On top of this, Gymnasium implements stochastic frame skipping: In each environment step, the action is repeated for a random
|
||
number of frames. This behavior may be altered by setting the keyword argument <code class="docutils literal notranslate"><span class="pre">frameskip</span></code> to either a positive integer or
|
||
a tuple of two positive integers. If <code class="docutils literal notranslate"><span class="pre">frameskip</span></code> is an integer, frame skipping is deterministic, and in each step the action is
|
||
repeated <code class="docutils literal notranslate"><span class="pre">frameskip</span></code> many times. Otherwise, if <code class="docutils literal notranslate"><span class="pre">frameskip</span></code> is a tuple, the number of skipped frames is chosen uniformly at
|
||
random between <code class="docutils literal notranslate"><span class="pre">frameskip[0]</span></code> (inclusive) and <code class="docutils literal notranslate"><span class="pre">frameskip[1]</span></code> (exclusive) in each environment step.</p>

|

<p>When initializing Atari environments via <code class="docutils literal notranslate"><span class="pre">gymnasium.make</span></code>, you may pass some additional arguments. These work for any

<li><p><strong>mode</strong>: <code class="docutils literal notranslate"><span class="pre">int</span></code>. Game mode, see <a class="reference internal" href="#id2"><span class="std std-ref">[2]</span></a>. Legal values depend on the environment and are listed in the table above.</p></li>
|

<li><p><strong>difficulty</strong>: <code class="docutils literal notranslate"><span class="pre">int</span></code>. The difficulty of the game, see <a class="reference internal" href="#id2"><span class="std std-ref">[2]</span></a>. Legal values depend on the environment and are listed in
|
||
the table above. Together with <code class="docutils literal notranslate"><span class="pre">mode</span></code>, this determines the “flavor” of the game.</p></li>
|
||
<li><p><strong>obs_type</strong>: <code class="docutils literal notranslate"><span class="pre">str</span></code>. This argument determines what observations are returned by the environment. Its values are:</p>
|
||
<ul>
|
||
<li><p>ram: The 128 Bytes of RAM are returned</p></li>
|
||
<li><p>rgb: An RGB rendering of the game is returned</p></li>

<li><p>grayscale: A grayscale rendering is returned</p></li>

<li><p><strong>frameskip</strong>: <code class="docutils literal notranslate"><span class="pre">int</span></code> or a tuple of two <code class="docutils literal notranslate"><span class="pre">int</span></code>s. This argument controls stochastic frame skipping, as described in the section on stochasticity.</p></li>

<li><p><strong>repeat_action_probability</strong>: <code class="docutils literal notranslate"><span class="pre">float</span></code>. The probability that an action sticks, as described in the section on stochasticity.</p></li>
