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:

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.
