tf_agents.agents.data_converter.DataContext

A class that stores useful data for performing data conversions.

tf_agents.agents.data_converter.DataContext(
    time_step_spec: tf_agents.trajectories.TimeStep,
    action_spec: tf_agents.typing.types.NestedTensorSpec,
    info_spec: tf_agents.typing.types.NestedTensorSpec,
    policy_state_spec: tf_agents.typing.types.NestedTensorSpec = (),
    use_half_transition: bool = False
)

time_step_spec A nest of tf.TimeStep representing the time_steps.
action_spec A nest of tf.TypeSpec representing the actions.
info_spec A nest of tf.TypeSpec representing the policy's info. (Typically this is the info emitted by the collect policy).
policy_state_spec A nest of tf.TypeSpec representing the policy's state.
use_half_transition A special transition that the next_time_step contains a dummy observation.

TypeError If any of the specs are not nests containing tf.TypeSpec objects.
