tf.linalg.global_norm

View source on GitHub

Computes the global norm of multiple tensors.

Given a tuple or list of tensors t_list, this operation returns the global norm of the elements in all tensors in t_list. The global norm is computed as:

global_norm = sqrt(sum([l2norm(t)**2 for t in t_list]))

Any entries in t_list that are of type None are ignored.

Args
t_list A tuple or list of mixed Tensors, IndexedSlices, or None.
name A name for the operation (optional).
Returns
A 0-D (scalar) Tensor of type float.
Raises
TypeError If t_list is not a sequence.
