Run your repo in tensorflow 1.1.0

Hi KnHuq,
Thanks for your code! I can learn a lot about the tensorflow usage. But when I ran your code in newer tf version, like 1.1.0, some functions need to be changed, e.g. tf.pack and tf.unpack.
After the modifications, I still encounter the problem "axis 0 specified more than once" at this line of code "sess.run(train_step, feed_dict={rnn._inputs: X, y: Y})".
I was stopped by this problem for two days, currently I don't know what I can do. can you help me figure out the reason?

Thanks for reaching to me. I will go through the code and update it to support latest tensorflow version.
