Hi,

I'm having a weird issue with floats in dictionaries and equality comparison (see attached screenshot for an example). When I create two dictionaries with a nan value they pass an equivalence test. However, if I pickle and unpickle one of the dictionaries they become no longer equivalent. I would expect that the behavior would be the same irrespective of whether they are pickled/unpickled. Is there something else I should be doing here or is there a way to easily resolve this (short of writing custom ways to compare equality)?
