All,
On my iMac at work running 10.6.8, I did a brew-based installation of Python
2.7.2. I used pip to install scipy, numpy and then matplotlib. The last didn't
work right so I scoured the internets to find out what to do. The first
solution I found suggested doing a git clone of the repository and running
python setup.py build then python setup.py install. That worked just great.
At home, I tried the same thing on my MBP running 10.6.8. When I got to the
compile matplotlib step, the fix from above didn't work. So I started trying
other solutions I had found. Many of them "worked", however, when I went to run
this simple script:
import matplotlib.pylab as plt
from scipy.stats import norm
I got this error:
Traceback (most recent call last):

line 464, in get_weight
return self._header['Weight']
KeyError: 'Weight'
Googling did not reveal a single occurrence of this error reported anywhere.
And so I would move on to the next instructions for compilation including the
original make.osx instructions...and while the compilations succeeded, I still
got the same error. Finally I decided to try the Enthought completely
pre-compiled and packaged installation. Same problem.
I'm at a loss. I even completely erased my /usr/local/ directory so that
everything would be consistently installed via Homebrew. But no matter what I
do, I end up with the same problem.
I'm considering that something is wrong with my Snow Leopard installation and
perhaps (reluctantly) upgrading to Lion, something I haven't really felt
compelled to do. I'm hoping that there is a setting that I neglected.
Ideas?
Thanks,
Steve
