Import a ConcreteFunction and convert it to a textual MLIR module.

This API is only intended for inspecting the internals of TensorFlow and the string returned is at the moment intended for debugging purposes.

A tf.function can be imported and converted from TensorFlow to TensorFlow MLIR with this API by extracting its ConcreteFunction (eagerly-executing wrapper around a tf.Graph).

For example:

@tf.function ... def add(a, b): ... return a + b

concrete_function = add.get_concrete_function(
    tf.TensorSpec(None, tf.dtypes.float32),
    tf.TensorSpec(None, tf.dtypes.float32))
'...module attributes {...} {...}'

concrete_function An object of type ConcreteFunction.
pass_pipeline A textual description of an MLIR Pass Pipeline to run on the module, see MLIR documentation for the textual pass pipeline syntax.

A textual representation of the MLIR module corresponding to the ConcreteFunction.

InvalidArgumentError if concrete_function is invalid or cannot be converted to MLIR.
