If the actor network is probabilistic and uses a :class:`~tensordict.nn.distributions.CompositeDistribution`,
this class must be used with tensordicts and cannot function as a tensordict-independent module.
This is because composite action spaces inherently rely on the structured representation of data provided by
tensordicts to handle their actions.
