|

<p>This wrapper converts the info format of a

vector environment from a dictionary to a list of dictionaries.
|

This wrapper is intended to be used around vectorized
|

environments. If using other wrappers that perform
|

operation on info like <cite>RecordEpisodeStatistics</cite> this
|
||
need to be the outermost wrapper.</p>
|
