tf.compat.v1.estimator.TrainSpec

tf.estimator.TrainSpec(
    input_fn, max_steps=None, hooks=None
)

TrainSpec determines the input data for the training, as well as the duration. Optional hooks run at various stages of training.

Args
input_fn	A function that provides input data for training as minibatches. See Premade Estimators for more information. The function should construct and return one of the following: A 'tf.data.Dataset' object: Outputs of Dataset object must be a tuple (features, labels) with same constraints as below. A tuple (features, labels): Where features is a Tensor or a dictionary of string feature name to Tensor and labels is a Tensor or a dictionary of string label name to Tensor.
max_steps	Int. Positive number of total steps for which to train model. If None, train forever. The training input_fn is not expected to generate OutOfRangeError or StopIteration exceptions. See the train_and_evaluate stop condition section for details.
hooks	Iterable of tf.train.SessionRunHook objects to run on all workers (including chief) during training.

Raises
ValueError	If any of the input arguments is invalid.
TypeError	If any of the arguments is not of the expected type.
