tf.train.string_input_producer(string_tensor, num_epochs=None, shuffle=True, seed=None, capacity=32, shared_name=None, name=None, cancel_op=None)

See the guide: Inputs and Readers > Input pipeline

Output strings (e.g. filenames) to a queue for an input pipeline.

Note: if num_epochs is not None, this function creates local counter epochs. Use local_variables_initializer() to initialize local variables.

Args:

  • string_tensor: A 1-D string tensor with the strings to produce.
  • num_epochs: An integer (optional). If specified, string_input_producer produces each string from string_tensor num_epochs times before generating an OutOfRange error. If not specified, string_input_producer can cycle through the strings in string_tensor an unlimited number of times.
  • shuffle: Boolean. If true, the strings are randomly shuffled within each epoch.
  • seed: An integer (optional). Seed used if shuffle == True.
  • capacity: An integer. Sets the queue capacity.
  • shared_name: (optional). If set, this queue will be shared under the given name across multiple sessions.
  • name: A name for the operations (optional).
  • cancel_op: Cancel op for the queue (optional).

Returns:

A queue with the output strings. A QueueRunner for the Queue is added to the current Graph's QUEUE_RUNNER collection.

Raises:

  • ValueError: If the string_tensor is a null Python list. At runtime, will fail with an assertion if string_tensor becomes a null tensor.
