Getting "Button is not defined" error

NameError Traceback (most recent call last)

NameError: name 'Button' is not defined

I have reduced my dataset size to an hour all split up into 5-10 second files. Previously when my data set was too big, I was told both minibatch and traceback were both not defined before, but now it's button.
