tf_agents.utils.common.discounted_future_sum_masked

Discounted future sum of batch-major values.

tf_agents.utils.common.discounted_future_sum_masked(
    values, gamma, num_steps, episode_lengths
)

Args
`values`	A Tensor of shape [batch_size, total_steps] and dtype float32.
`gamma`	A float discount value.
`num_steps`	A positive integer number of future steps to sum.
`episode_lengths`	A vector shape [batch_size] with num_steps per episode.

Returns
A Tensor of shape [batch_size, total_steps], where each entry is the discounted sum as in discounted_future_sum, except with values after the end of episode_lengths masked to 0.

Raises
`ValueError`	If values is not of rank 2, or if total_steps is not defined.
