tf.estimator.inputs.pandas_input_fn( x, y=None, batch_size=128, num_epochs=1, shuffle=None, queue_capacity=1000, num_threads=1, target_column='target' )
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 matchx
's index.
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
.Function, that has signature of ()->(dict of features
, target
)
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.
