<li><p><strong>shared_memory</strong> – If <code class="docutils literal notranslate"><span class="pre">True</span></code>, then the observations from the worker processes are communicated back through
shared variables. This can improve the efficiency if the observations are large (e.g. images).</p></li>

<li><p><strong>context</strong> – Context for <cite>multiprocessing</cite>. If <code class="docutils literal notranslate"><span class="pre">None</span></code>, then the default context is used.</p></li>
<li><p><strong>daemon</strong> – If <code class="docutils literal notranslate"><span class="pre">True</span></code>, then subprocesses have <code class="docutils literal notranslate"><span class="pre">daemon</span></code> flag turned on; that is, they will quit if
the head process quits. However, <code class="docutils literal notranslate"><span class="pre">daemon=True</span></code> prevents subprocesses to spawn children,
so for some environments you may want to have it set to <code class="docutils literal notranslate"><span class="pre">False</span></code>.</p></li>
<li><p><strong>worker</strong> – If set, then use that worker in a subprocess instead of a default one.
Can be useful to override some inner vector env logic, for instance, how resets on termination or truncation are handled.</p></li>
<li><p><strong>observation_mode</strong> – Defines how environment observation spaces should be batched. ‘same’ defines that there should be <code class="docutils literal notranslate"><span class="pre">n</span></code> copies of identical spaces.
‘different’ defines that there can be multiple observation spaces with different parameters though requires the same shape and dtype,
warning, may raise unexpected errors. Passing a <code class="docutils literal notranslate"><span class="pre">Tuple[Space,</span> <span class="pre">Space]</span></code> object allows defining a custom <code class="docutils literal notranslate"><span class="pre">single_observation_space</span></code> and
