Description

ML.NETs Transforms.Conversion.MapValueToKey() adds a UInt32 column with an auto generated integer category key.
Unfortunately the resulting dataview crashes when trying to convert to ToDataFrame(), because it does not support UInt32.

However converting to DataFrame is essential to easily display the results in a Jupyter Notebook (which works nicely in VS Code for DataFrames).
