Handling corner cases

[MKatereggaExigent]

The library fails on dataframes where column types are not explicitly defined. For instance in cases where a continuous column has text, the following error is returned:

TypeError: unsupported operand type(s) for +: 'int' and 'str'

It will be great to have an intelligent library that would auto-fix such.

It would be great if you could mention the function that you're trying to call and also add the complete error message.
