seems problem keras , not tensorflow according post enter link description here wondering if has been fixed yet?

this problem between keras , tensorflow. should change fix use like

if hasattr(tf.contrib, 'ctc'):   ctc = tf.contrib.ctc  # old version else:   ctc = tf.nn  # new official version.

the current "official" way access ctc operations in tf.nn, instance, tf.nn.ctc_loss.
