exception andrey.DataTypeWarning

How a call reads its columns’ types: inferred, missing, or possibly mistaken.

A mixed-data test or score warns when it infers the categorical columns or finds none, and so runs as its linear-Gaussian form; a continuous one warns once when columns look like category codes. A score search left at score_func=None warns once when it picks BDeu because every column is categorical, or the conditional Gaussian BIC because some are.
