torcheval.metrics.functional.throughput¶

torcheval.metrics.functional.throughput(num_processed: int = 0, elapsed_time_sec: float = 0.0) → Tensor¶

Calculate the throughput value which is the number of elements processed per second. Its class version is torcheval.metrics.Throughput.

Parameters:

num_processed (int) – Number of items processed.
elapsed_time_sec (float) – Total elapsed time in seconds to process num_processed items.

Raises:

ValueError – If num_processed is a negative number. If elapsed_time_sec is a non-positive number.

Examples:

>>> import torch
>>> from torcheval.metrics.functional import throughput
>>> throughput(64, 2.0)
tensor(32.)
