tf.contrib.framework.assert_or_get_global_step(graph=None, global_step_tensor=None)

See the guide: Framework (contrib) > Variables

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.
