This causes few issues like

being unable to broadcast
need to write different version of cost function calculation: (1-y).values.flatten() instead of (1-y)

It's better to unify the data type as numpy array to reduce confusion from users.

One quick fix would be using

from sklearn.preprocessing import PolynomialFeatures

PolynomialFeatures(6)
