tf_agents.agents.ppo.ppo_utils.distribution_from_spec

Convert (spec, new_distribution_params) -> Distribution.

tf_agents.agents.ppo.ppo_utils.distribution_from_spec(
    spec: tf_agents.typing.types.NestedTensorSpec,
    new_distribution_params: tf_agents.typing.types.NestedTensor,
    legacy_distribution_network: bool
) -> tf_agents.typing.types.NestedDistribution

new_distribution_params typically comes from a logged policy info.

Args
`spec`	A nested tensor spec. If `legacy_distribution_network` is `True`, these are typically `actor_net.output_spec`. If it's `False`, these are typically the output of `actor_net.create_variables()`.
`new_distribution_params`	Parameters to merge with the spec to create a new distribution. These were typically emitted by `get_distribution_params` and stored in the replay buffer.
`legacy_distribution_network`	`True` if the spec and params were generated from a `network.DistributionNetwork`.

Returns
A (possibly nested set of) `Distribution` created from the spec merged with the new params.
