Defined in tensorflow/python/estimator/inputs/pandas_io.py.

Returns input function that would feed Pandas DataFrame into the model.

Note: y's index must match x's index.

Args:

• x: pandas DataFrame object.
• y: pandas Series object. None if absent.
• batch_size: int, size of batches to return.
• num_epochs: int, number of epochs to iterate over data. If not None, read attempts that would exceed this value will raise OutOfRangeError.
• shuffle: bool, whether to read the records in random order.
• queue_capacity: int, size of the read queue. If None, it will be set roughly to the size of x.
• num_threads: Integer, number of threads used for reading and enqueueing. In order to have predicted and repeatable order of reading and enqueueing, such as in prediction and evaluation mode, num_threads should be 1.
• target_column: str, name to give the target column y.

Returns:

Function, that has signature of ()->(dict of features, target)

Raises:

• ValueError: if x already contains a column with the same name as y, or if the indexes of x and y don't match.
• TypeError: shuffle is not bool.
