Returns a Trajectory
given transitions.
tf_agents.trajectories.from_transition(
time_step: tf_agents.trajectories.TimeStep
,
action_step: tf_agents.trajectories.PolicyStep
,
next_time_step: tf_agents.trajectories.TimeStep
) -> tf_agents.trajectories.Trajectory
Used in the notebooks
from_transition
is used by a driver to convert sequence of transitions into
a Trajectory
for efficient storage. Then an agent (e.g.
ppo_agent.PPOAgent
) converts it back to transitions by invoking
to_transition
.
Note that this method does not add a time dimension to the Tensors in the
resulting Trajectory
. This means that if your transitions don't already
include a time dimension, the Trajectory
cannot be passed to
agent.train()
.
