Lesson 4 IMDB: can't run the training code

I’m running the notebook for lesson 4, without any changes: https://github.com/fastai/fastai/blob/master/courses/dl1/lesson4-imdb.ipynb But this code: learner.fit(3e-3, 4, wds=1e-6, cycle_len=1, cycle_mult=2) from the section on training the model produces a RuntimeError: RuntimeError: shape ‘[1000000, 1]’ is invalid for input of size 2000 How can I fix this ?
