Getting an deprecation warning

[hellmersjl3ds]

When executing W, THETA, PHI = spin_wigner(psi, theta, phi) I get the message /home/jhellmers/anaconda3/lib/python3.6/site-packages/scipy/sparse/compressed.py:845: VisibleDeprecationWarning: using a non-integer number instead of an integer will result in an error in the future start = self.indptr[major_index] /home/jhellmers/anaconda3/lib/python3.6/site-packages/scipy/sparse/compressed.py:846: VisibleDeprecationWarning: using a non-integer number instead of an integer will result in an error in the future end = self.indptr[major_index+1]

This was in the Adiabatic Quantum Computing lecture notebook.
