Probably not. While Traits triggers the execution of the failing code,
the last line is pure numpy, and the error message comes from
numpy.array(). You then do what one normally does to debug a TypeError
being thrown by a function: find out the type and value of the inputs
being given to the function either by print statements or a debugger.

enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
