tf.train.get_global_step(graph=None)
Defined in tensorflow/python/training/training_util.py.
Get the global step tensor.
The global step tensor must be an integer variable. We first try to find it
in the collection GLOBAL_STEP, or by name global_step:0.
Args:
graph: The graph to find the global step in. If missing, use default graph.
Returns:
The global step variable, or None if none was found.
Raises:
TypeError: If the global step tensor has a non-integer type, or if it is not aVariable.
