<dd><p>Flatten a space into a space that is as flat as possible.</p>
|
||
<p>This function will attempt to flatten <code class="docutils literal notranslate"><span class="pre">space</span></code> into a single <a class="reference internal" href="../fundamental/#gymnasium.spaces.Box" title="gymnasium.spaces.Box"><code class="xref py py-class docutils literal notranslate"><span class="pre">gymnasium.spaces.Box</span></code></a> space.
|
||
However, this might not be possible when <code class="docutils literal notranslate"><span class="pre">space</span></code> is an instance of <a class="reference internal" href="../composite/#gymnasium.spaces.Graph" title="gymnasium.spaces.Graph"><code class="xref py py-class docutils literal notranslate"><span class="pre">gymnasium.spaces.Graph</span></code></a>,

<a class="reference internal" href="../composite/#gymnasium.spaces.Sequence" title="gymnasium.spaces.Sequence"><code class="xref py py-class docutils literal notranslate"><span class="pre">gymnasium.spaces.Sequence</span></code></a> or a compound space that contains a <a class="reference internal" href="../composite/#gymnasium.spaces.Graph" title="gymnasium.spaces.Graph"><code class="xref py py-class docutils literal notranslate"><span class="pre">gymnasium.spaces.Graph</span></code></a>

This is equivalent to <a class="reference internal" href="#gymnasium.spaces.utils.flatten" title="gymnasium.spaces.utils.flatten"><code class="xref py py-func docutils literal notranslate"><span class="pre">flatten()</span></code></a>, but operates on the space itself. The

Flattening a sample
|
||
of the original space has the same effect as taking a sample of the flattened
|
||
space. However, sampling from the flattened space is not necessarily reversible.
|
||
For example, sampling from a flattened Discrete space is the same as sampling from
|
||
a Box, and the results may not be integers or one-hot encodings. This may result in
|
||
errors or non-uniform sampling.</p>
