tf.contrib.framework.assert_or_get_global_step

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.
