Return a tuple containing a function which converts a list into a numpy array and the type produced by the converter function.

numpy_type : numpy data-type

The numpy type required of an array returned by converter. Must be a valid numpy type, e.g., numpy.uint, numpy.int8, numpy.int64, numpy.float, numpy.float64, numpy.str.

(converter, converter_type) : (function, generic data-type)

converter is a function which accepts a list and converts it to a numpy array of type numpy_type. converter_type tracks the generic data type produced by the converter function.


Raised by converter if the list elements could not be converted to the required type.
