StopIteration Error #17

Hi,

Thank you for a nice implementation. Unfortunately, when I'm trying to run the test example, I bump into two problems.

  1. Local variable "full_sequences" referenced before assignment on line 101 dataset.py (I can fix this by assigning full_sequences = [] before the two for loops)
  2. File "wavenet.py", line 326, in predict outputs = list(data_generators['test'].next()[0][-1]) StopIteration

This one I can't figure out.

Any ideas?

Have you solved it?

I have the same problem as below:
