Standard names to use for graph collections.

The standard library uses various well-known names to collect and retrieve values associated with a graph. For example, thetf.Optimizer subclasses default to optimizing the variables collected under tf.GraphKeys.TRAINABLE_VARIABLES if none is specified, but it is also possible to pass an explicit list of variables.

The following standard keys are defined:

GLOBAL_VARIABLES: the default collection of Variable objects, shared across distributed environment (model variables are subset of these). Seetf.compat.v1.global_variablesfor more details. Commonly, all TRAINABLE_VARIABLES variables will be in MODEL_VARIABLES, and all MODEL_VARIABLES variables will be in GLOBAL_VARIABLES.
LOCAL_VARIABLES: the subset of Variable objects that are local to each machine. Usually used for temporarily variables, like counters.
MODEL_VARIABLES: the subset of Variable objects that are used in the model for inference (feed forward).
TRAINABLE_VARIABLES: the subset of Variable objects that will be trained by an optimizer. Seetf.compat.v1.trainable_variablesfor more details.
SUMMARIES: the summary Tensor objects that have been created in the graph. Seetf.compat.v1.summary.merge_allfor more details.
QUEUE_RUNNERS: the QueueRunner objects that are used to produce input for a computation. Seetf.compat.v1.train.start_queue_runnersfor more details.
MOVING_AVERAGE_VARIABLES: the subset of Variable objects that will also keep moving averages. Seetf.compat.v1.moving_average_variablesfor more details.
REGULARIZATION_LOSSES: regularization losses collected during graph construction.

The following standard keys are defined, but their collections are notautomatically populated as many of the others are:
