tf.contrib.framework.get_graph_from_inputs

Returns the appropriate graph to use for the given inputs.

tf.contrib.framework.get_graph_from_inputs(
    op_input_list, graph=None
)

If graph is provided, we validate that all inputs in op_input_list are from the same graph.
Otherwise, we attempt to select a graph from the first Operation- or Tensor-valued input in op_input_list, and validate that all other such inputs are in the same graph.
If the graph was not specified and it could not be inferred from op_input_list, we attempt to use the default graph.

Args
`op_input_list`	A list of inputs to an operation, which may include `Tensor`, `Operation`, and other objects that may be converted to a graph element.
`graph`	(Optional) The explicit graph to use.

Raises
`TypeError`	If `op_input_list` is not a list or tuple, or if graph is not a Graph.
`ValueError`	If a graph is explicitly passed and not all inputs are from it, or if the inputs are from multiple graphs, or we could not find a graph and there was no default graph.

Returns
The appropriate graph to use for the given inputs.
