tf.contrib.learn.build_parsing_serving_input_fn(feature_spec, default_batch_size=1)

See the guide: Learn (contrib) > Input processing

Build an input_fn appropriate for serving, expecting fed tf.Examples.

Creates an input_fn that expects a serialized tf.Example fed into a string placeholder. The function parses the tf.Example according to the provided feature_spec, and returns all parsed Tensors as features. This input_fn is for use at serving time, so the labels return value is always None.

Args:

• feature_spec: a dict of string to VarLenFeature/FixedLenFeature.
• default_batch_size: the number of query examples expected per batch.

Returns:

An input_fn suitable for use in serving.
