tf.contrib.framework.assert_or_get_global_step(
graph=None,
global_step_tensor=None
)
Defined in tensorflow/contrib/framework/python/ops/variables.py.
Verifies that a global step tensor is valid or gets one if None is given.
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.
