Problems in interpolation_helper.py

[nonstopfor]

In examples/seq2seq_exposure_bias, I ran interpolation_main.py as the README told me. However, the program crashed. Here is the key error at line 127 in interpolation_helper.py:
[state[0][:, :time], tf.expand_dims(sample_ids, 1) TypeError: tuple indices must be integers or slices, not tuple
What's wrong with that?
And I find that the problem seems be relevant with commit 2307d99. Could anybody help to solve that? Thanks!
