Returns the set of global variables in this graph.
Returns the set of global variables in this graph.
Global variables are variables that are shared across machines in a distributed environment. The Variable()

An alternative to global variables are local variables.

Imports a serialized representation of a graph into the current graph.
Serialized representation of the graph that will be imported into this graph.
Optional prefix that will be prepended to all node names in the graph that is being imported to this graph.
Optional inputs mapping. For each
(source_op_name, source_op_output_index) -> destination_op_output mapping, the
importer will set any imported nodes with input named
source_op_name:source_op_output_index to have that input replaced with
destination_op_output. source_op_name refers to a node in the graph to be
imported, whereas destination_op_output references a node already existing in
this graph.
Optional control dependencies mapping. For each source_op_name -> destination_op
mapping, the importer will set any imported ops with control input named
source_op_name to have that input replaced with destination_op.
source_op_name refers to a node in the graph to be imported, whereas
destination_op references an op already existing in this graph.

destination_op_output. source_op_name refers to a node in the graph to be
imported, whereas destination_op_output references a node already existing
in this graph.

source_op_name -> destination_op mapping, the importer will set any imported
ops with control input named source_op_name to have that input replaced with

imported, whereas destination_op references an op already existing in this
graph.
Optional control dependencies set. The importer will make sure that the imported graph has a control dependency on all ops in this set. All such ops, should therefore be defined in this graph.

Returns the set of local variables in this graph.
Returns the set of local variables in this graph.
Local variables (or per-process variables), are usually not saved/restored to/from checkpoints and are used for temporary or intermediate values. For example, they can be used as counters for metrics computations or number of epochs this machine has read data. This convenience function returns the contents of that collection.
An alternative to local variables are global variables.

Graph extension helper for constructing a function.
A FunctionGraph keeps track of all inputs into every op created inside it. If any input is from another graph, we keep track of it and substitute the input with a placeholder.
Each captured input's corresponding placeholder is converted into a function argument and the caller passes in the captured tensor.
