tf.compat.v1.estimator.inputs.pandas_input_fn
Returns input function that would feed Pandas DataFrame into the model.
tf.compat.v1.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'
)
Note: y
's index must match x
's index.
Args |
x
|
pandas DataFrame object.
|
y
|
pandas Series object or DataFrame . 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 . This parameter is
not used when y is a DataFrame .
|
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.
|
ValueError
|
if 'shuffle' is not provided or a bool.
