Hi,
I have been having problems trying to install matplotlib properly on
our server. Our environment is Debian 4.1.1-21, Python2.4 , and I have
installed all the required modules (numpy, Numeric etc). I originally
tried installing matplotlib from source, but the build was
unsuccessful. I was getting this error when I tried building
matplotlib-0.90.1:
python setup.py build

your build/install environment

So I tried installing matplotlib from distribution (ie. using apt-get
install python-matplotlib), thinking it may work instead of me trying
to manually install it. The distribution installs matplotlib-0.87.7,
which is older than the current version available by source. And it
seemed to compile fine without any errors. However, when I try to
import pylab using python command line, I get this error:
import matplotlib
import pylab
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "pylab.py", line 1, in ?
from matplotlib.pylab import *

File "matplotlib/numerix/_sp_imports.py", line 9, in ?
from numpy import Int8, UInt8, \
ImportError: cannot import name Int8
I think this Debian distribution of matplotlib (which is older than
the current release) is incompatible with the current version of
numpy/Numeric that I have installed, but I'm not sure. I would rather
have the latest matplotlib vesrion installed (version 0.90.1), but I
can't seem to get it to even build properly.
I'm stumped and I'm hoping someone has an idea why I might be getting
this error, and how I can get around it. Please let me know if you
need more information if it helps understand the problem better.
Thanks in advance,
best,
Hardeep
