Verifies that a global step tensor is valid or gets one if None is given.
tf.contrib.framework.assert_or_get_global_step(
graph=None, global_step_tensor=None
)
If global_step_tensor
is not None, check that it is a valid global step
tensor (using assert_global_step
). Otherwise find a global step tensor using
get_global_step
and return it.
Args |
graph
|
The graph to find the global step tensor for.
|
global_step_tensor
|
The tensor to check for suitability as a global step. If
None is given (the default), find a global step tensor.
|
Returns |
A tensor suitable as a global step, or None if none was provided and none
was found.
