Hello,
I am attempting to write a small simulation to reproduce something
from a paper. However, I'm having a whale of a time getting it to
work (as far as I have been able to tell, the calculations from the
paper at least are identical to what I am trying to do, which makes
this all the more frustrating). I recently discovered that if I import
pylab after importing numpy, I get tons of warnings:
Warning: divide by zero encountered in divide
Warning: invalid value encountered in multiply
Warning: overflow encountered in long_scalars
with the last occurring far most often (interestingly, I do not get
these warnings if pylab is imported before numpy). My question then is
two fold:
(1) Why do I only get these warnings depending on when I import pylab?
(2) (a more general python question) How can I get these warning
messages to give me *useful* information, such as where the problems
are happening?
Thanks,
