Utilities related to distributions.

## Classes

[`class DistributionSpecV2`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/DistributionSpecV2): Describes a tfp.distribution.Distribution using nested parameters.

[`class Params`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/Params): The (recursive) parameters of objects exposing the `parameters` property.

[`class SquashToSpecNormal`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/SquashToSpecNormal): Scales an input normalized action distribution to match spec bounds.

## Functions

[`assert_specs_are_compatible(...)`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/assert_specs_are_compatible): Checks that the output of [`network.create_variables`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/networks/network/create_variables) matches a spec.

[`get_parameters(...)`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/get_parameters): Creates a recursive `Params` object from `value`.

[`make_from_parameters(...)`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/make_from_parameters): Creates an instance of type `value.type_` with the parameters in `value`.

[`merge_to_parameters_from_dict(...)`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/merge_to_parameters_from_dict): Merges dict matching data of `parameters_to_dict(value)` to a new `Params`.

[`parameters_to_dict(...)`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/parameters_to_dict): Converts `value` to a nested `dict` (excluding all `type_` info).

[`scale_distribution_to_spec(...)`](https://www.tensorflow.org/agents/api_docs/python/tf_agents/distributions/utils/scale_distribution_to_spec): Scales the given distribution to the bounds of the given spec.
