@mrry @girving @ry hi merry, sorry to bother you. It seems that the problem still occurs in the latest tensorflow 1.2.1. I run the code provided by @yaroslavvb and get the errors.

I use ubuntu 14.04 , tensorflow-gpu 1.2.1, titianx-black

@vanpersie32 That error is unrelated: the calling convention of tf.reverse changed with 1.0 to match numpy. See https://www.tensorflow.org/api_docs/python/tf/reverse.
