It allows you to take a bunch of TensorFlow ops and annotate the construction such that toco knows how to convert it to tflite. This embeds a pseudo function in a TensorFlow graph. This allows embedding high-level API usage information in a lower level TensorFlow implementation so that an alternative implementation can be substituted later.
Essentially, any "input" into this pseudo op is fed into an identity, and attributes are added to that input before being used by the constituent ops that make up the pseudo op. A similar process is done to any output that is to be exported from the current op.
Args
function_name
Name of the function (the custom op name in tflite)
level
OpHint level.
children_inputs_mappings
Children OpHint inputs/outputs mapping. children_inputs_mappings should like below: "parent_first_child_input": [{"parent_input_index": num, "child_input_index": num}, ...] "parent_last_child_output": [{"parent_output_index": num, "child_output_index": num}, ...] "internal_children_input_output": [{"child_input_index": num, "child_output_index": num}, ...]
**kwargs
Keyword arguments of any constant attributes for the function.
"name" label "tag" a tag to group multiple arguments that will be aggregated. I.e. a string like 'cool_input'. Basically multiple inputs can be added to the same hint for parallel operations that will eventually be combined. An example would be static_rnn which creates multiple copies of state or inputs. "aggregate" aggregation strategy that is valid only for tag non None. Acceptable values are OpHint.AGGREGATE_FIRST, OpHint.AGGREGATE_LAST, and OpHint.AGGREGATE_STACK. "index_override" The global index to use. This corresponds to the argument order in the final stub that will be generated.
