Community matplotlib-users
#1

Hello,
I am new to matplotlib. My system administrator installed matplotlib (using gentoo's emerge command). There were no errors while installation, but wen i try to import pylab i get an error:

markacy@...632...:~>python
Python 2.3.5 (#1, Apr 28 2005, 10:18:07)
[GCC 3.3.5-20050130 (Gentoo Linux 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, pie- on linux2
Type "help", "copyright", "credits" or "license" for more information.

from pylab import *

Traceback (most recent call last):
   File "<stdin>", line 1, in ?
ImportError: No module named pylab

What is the problem??
Thanks,
Marek

Hi Marek,

I just installed Matplotlib via gentoo's emerge (a first for me) and had no
problem with from pylab import *. I think you may need to take it up with
your sysadmin. Make sure dev-python/matplotlib is added to your
package.keywords file. The 0.80 version is stable, although it is masked as
testing (~) in the gentoo tree.

Try
~> locate matplotlib

I think you have version 0.64, which did not include the change from
matplotlib.matlab to matplotlib.pylab. I'll try to find someone to mark the
most recent version as stable in the gentoo tree. I can almost guarantee this
to be the source of your problem.

You were right, Darren, it was the problem. from matplotlib.matlab import * works just fine:)
Thanks very much.

You won't know until you address the syntax error
('form').

Well, that was quick. Matplotlib-0.71 has been marked stable in the gentoo
tree, version 0.64 and 0.65 have been removed.

you typed "form" instead of "from".

I hope this helps,
