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]) +

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
T = random.random((2,d,d))
W = random.random((2,d,d,i))
and d 2. For d = 3 it fails for i = 911...1365.
Should I submit this as a bug (if so, how do I do that?) and/or
contact the author Mark Wiebe?

PS: How

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!
