Converts a graphdef with LiteOp hints into stub operations.
tf.lite.experimental.convert_op_hints_to_stubs( session=None, graph_def=None, write_callback=(lambda graph_def, comments: None) )
This is used to prepare for toco conversion of complex intrinsic usages. Note: only one of session or graph_def should be used, not both.
session: A TensorFlow session that contains the graph to convert.
graph_def: A graph def that we should convert.
write_callback: A function pointer that can be used to write intermediate steps of graph transformation (optional).
A new graphdef with all ops contained in OpHints being replaced by a single op call with the right parameters.
ValueError: If both session and graph_def are provided.
