[BUG] ImportError: cannot import name 'csr_matrix' from 'scipy.sparse' (unknown location)

[suciokhan]

Describe the bug

I just pip-installed Pomegranate into an Anaconda environment after receiving a similar error after conda installation. I'm attempting to do the example here: https://pomegranate.readthedocs.io/en/latest/tutorials/B_Model_Tutorial_6_Bayesian_Networks.html

When I run from pomegranate.distributions import Categorical I receive the following error chain:

---------------------------------------------------------------------------
