tf.contrib.framework.reduce_sum_n()

tf.contrib.framework.reduce_sum_n(tensors, name=None)

Reduce tensors to a scalar sum.

This reduces each tensor in tensors to a scalar via tf.reduce_sum, then adds them via tf.add_n.

Args:

• tensors: List of tensors, all of the same numeric type.
• name: Tensor name, and scope for all other ops.

Returns:

Total loss tensor, or None if no losses have been configured.

Raises:

• ValueError: if losses is missing or empty.
