Reads TFRecord, queues, batches and parses Example proto. (deprecated)

THIS FUNCTION IS DEPRECATED. It will be removed in a future version. Instructions for updating: Use tf.data.

See more detailed description in read_examples.

Args:

• file_pattern: List of files or patterns of file paths containing Example records. See tf.gfile.Glob for pattern rules.
• batch_size: An int or scalar Tensor specifying the batch size to use.
• features: A dict mapping feature keys to FixedLenFeature or VarLenFeature values.
• 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.
• reader_num_threads: The number of threads to read examples. In order to have predictable and repeatable order of reading and enqueueing, such as in prediction and evaluation mode, reader_num_threads should be 1.
• name: Name of resulting op.

Returns:

A dict of Tensor or SparseTensor objects for each in features.

Raises:

• ValueError: for invalid inputs.
