Fair enough -- though you'd probably get a big speed up moving to cython.
Indeed. If this is needed, we'll
Hello,
The science package I'm using fits legendre polynomials to data. I heard
it is more stable than the normal polynomials for a fit. Is there a
polyfit for legendre polynomials? How do I do that with the new legendre
polynomials module?
Thanks

Well, the hungarian algorithm has a theoretical upper bound of O(n^3),
with n being the number of nodes, which is pretty much the best you
can do if you have a dense graph and make no assumptions on
capacities.
OK, your input is making my motivation to fight with Jonker-Volgenant go
down.

Right now we are playing with the idea of integrating it in the scikits
learn, as it would be useful in a couple of places. I don't know

Hello,
I am encountering a very strange behaviour of einsum on my machine. I
tracked the problem down to the following test code:
from numpy import *
T = random.random((3,10,10))
W = random.random((3,10,7,275))
print all(einsum('ij...,j...-i...',T[0],W[0]) +

The equality being that the _expression_ should be ~0?
Exactly.
I see the problem when the last index is in the range 235 - 390.
Good to see I am not the only one - I was getting crazy. Same range for me by the way.
Out of curiosity, which machine/OS are you using? I'm on 64 bit

It also fails for

W = random.random((2,d,d,i))

Should I submit this as a bug (if so, how do I do that?) and/or

Thanks for your reply! I managed to open a ticket,
http://projects.scipy.org/numpy/ticket/1834
You are actually right, you can also just use zeros instead of random.
Maybe I can test a bit more tomorrow... but its 4am in the morning now ;-).
Thanks for your help and kindness!
