error using wavenet code

[sandeeppandey456]

I am getting the following error-

File "/media/eee/AA70975870972A59/Monthwise_experiments/april2019/wavenet-classifier-master/WaveNetClassifier.py", line 154, in fit
if self.task == 'classification':

AttributeError: 'WaveNetClassifier' object has no attribute 'task'

He forgot to add 'task' to class attributes, it is currently only visible in the constructor (init). Add the following line to the init function:
self.task = task
