mainTafl.py does not work for me

[rosnu]

mainTafl.py does not work; it looks for me like an inconsistency in handling board.
Coach expects for trainExamples (compared to Otello) from getNextState a ndarray, but gets Board objects.

  Traceback (most recent call last):
    File "mainTafl.py", line 34, in <module>

      boards = torch.FloatTensor(np.array(boards).astype(np.float64))
  ValueError: setting an array element with a sequence.
