Reads PTB text files, converts strings to integer ids, and performs mini-batching of the inputs. The PTB dataset comes from Tomas Mikolov's webpage: http://www.fit.vutbr.cz/~imikolov/rnnlm/simple-examples.tgz Args: data_path: string path to the directory where simple-examples.tgz has been extracted.
