I'm going over the Book Deep Learning with Python from F. Chollet. https://www.manning.com/books/deep-learning-with-python
I'm trying to follow along with the code examples. I just installed keras, and I am getting this error when trying to run this: from this notebook: https://github.com/fchollet/deep-learning-with-python-notebooks/blob/master/2.1-a-first-look-at-a-neural-network.ipynb
from keras import models

I'm wondering if there's something off with my installation?
keras.__version__
2.2.4
If anyone could give me a clue of what to look into.
