I understand where this error comes from, however what I was trying to do seems to "intuitive" that I would like to ask for suggestions: "What should I do if the "number" 2636 becomes unhashable ?"
In your example, that's the array which is unhashable, the numbers itself should be hashable. Arrays are mutable, so I don't think you can easily make them hashable. You could transform everything into tuple of tuple of... if you need to use set, though.
Use md5's of their .data attribute. This works quite well (you might want to hash a pickled string of the dtype in addition). Gaël
