1. On calculate_weights I got the following:

assert np.all([A.dtype == "int" for A in Symbol_matrices])
AssertionError

What should I do?

Answer:

Because of not so clear dtypes policies, pyitlib need all integer columns

as int type (col.dtype must return ‘str’). So to fix you can do:

Instead of:

bn.calculate_weights(discretized_data)

Convert dtypes to intc:

bn.calculate_weights(discretized_data.astype(np.intc))
