< 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 > ,

or < 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 > space.
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
result for non-graph spaces is always a < 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 > with flat boundaries. While
the result for graph spaces is always 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 > with
< code class = "xref py py-attr docutils literal notranslate" > < span class = "pre" > Graph.node_space< / span > < / code > being a < code class = "docutils literal notranslate" > < span class = "pre" > Box< / span > < / code >
with flat boundaries and < code class = "xref py py-attr docutils literal notranslate" > < span class = "pre" > Graph.edge_space< / span > < / code > being a < code class = "docutils literal notranslate" > < span class = "pre" > Box< / span > < / code > with flat boundaries or
< code class = "docutils literal notranslate" > < span class = "pre" > None< / span > < / code > . The box has exactly < a class = "reference internal" href = "#gymnasium.spaces.utils.flatdim" title = "gymnasium.spaces.utils.flatdim" > < code class = "xref py py-func docutils literal notranslate" > < span class = "pre" > flatdim()< / span > < / code > < / a > dimensions. 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 >
