Shifts batch-major values in time by some amount.
tf_agents.utils.common.shift_values(
values, gamma, num_steps, final_values=None
)
Args |
values
|
A Tensor of shape [batch_size, total_steps] and dtype float32.
|
gamma
|
A float discount value.
|
num_steps
|
A nonnegative integer amount to shift values by.
|
final_values
|
A float32 Tensor of shape [batch_size] corresponding to the
values at step num_steps + 1. Defaults to None (all zeros).
|
Returns |
A Tensor of shape [batch_size, total_steps], where each entry (i, j) is
gamma^num_steps * values[i, j + num_steps] if j + num_steps < total_steps;
gamma^(total_steps - j) * final_values[i] otherwise.
|
Raises |
ValueError
|
If values is not of rank 2.
