Adds operations to read, queue, batch
Example protos. (deprecated)
Given file pattern (or list of files), will setup a queue for file names,
Example proto using provided
reader, use batch queue to create
batches of examples of size
All queue runners are added to the queue runners collection, and may be
All ops are added to the default graph.
parse_fn if you need to do parsing / processing on single examples.
file_pattern: List of files or patterns of file paths containing
tf.gfile.Globfor pattern rules.
batch_size: An int or scalar
Tensorspecifying the batch size to use.
reader: A function or class that returns an object with
readmethod, (filename tensor) -> (example tensor).
randomize_input: Whether the input should be randomized.
num_epochs: Integer specifying the number of times to read through the dataset. If
None, cycles through the dataset forever. NOTE - If specified, creates a variable that must be initialized, so call
tf.local_variables_initializer()and run the op in a session.
queue_capacity: Capacity for input queue.
num_threads: The number of threads enqueuing examples. In order to have predictable and repeatable order of reading and enqueueing, such as in prediction and evaluation mode,
num_threadsshould be 1.
read_batch_size: An int or scalar
Tensorspecifying the number of records to read at once.
parse_fn: Parsing function, takes
ExampleTensor returns parsed representation. If
None, no parsing is done.
name: Name of resulting op.
seed: An integer (optional). Seed used if randomize_input == True.
Tensor of batched
ValueError: for invalid inputs.
