Returns the appropriate graph to use for the given inputs.
graphis provided, we validate that all inputs in
op_input_listare 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.
op_input_list: A list of inputs to an operation, which may include
Operation, and other objects that may be converted to a graph element.
graph: (Optional) The explicit graph to use.
op_input_listis 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.
