Comment #2 on issue 227 by Vinzent....@gmail.com: matrix slicing
broken
http://code.google.com/p/mpmath/issues/detail?id=227
I think this is a bug. The error means that the key of the element you
access (usually something like (0, 0) for instance) is not hashable. In
this case, "key" is a slice, which is apparently not hashable. I did not
implement matrix slicing, so I would have to look further into this to
understand the problem. It used to work however.
Which version of Python are you using?
Thanks for the response.
$: python --version
Python 2.7.1+
If there's anything else you need, just ask.
