Not included: where’s numpy? Where’s networkx? Where’s either scikit-learn or scipy.sparse.linalg? I’m not a C.S. undergrad. I can be coaxed into rewriting random forest regression or whatever but there are even more pressing underlying matters. What’s the pipeline for reading CSV files or querying sql databases and laying results out on a dataframe-like for transformations?
