Thread: [Matplotlib-users] ImportError: No module named pylab

I am using the latest svn version of matplotlib

Python 2.4.1 (#1, Sep 12 2005, 23:33:18)
[GCC 4.0.2 20050901 (prerelease) (SUSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> from pylab import *
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib64/python2.4/site-packages/pylab.py", line 1, in ?
    from matplotlib.pylab import *
ImportError: No module named pylab

This seems to be related to some of the recent changes.

Am I missing something ?

Nils

Dear all,

I'm unable to import pylab anymore, and I don't know why. It seems to=20
be due to environment variables. The sys.path leads to the correct=20
directories. I'm running Fedora 7 (I started using Matplotlib & Co. on=20
FC5, then due to the problems I had I upgraded to F7, but it still=20
doesn't work) Do you know if there is a conflict between scipy,=20
matplotlib and pylab. Problems seem to have started after I installed=20
scipy from the home:ashigabou.repo repository.

I can import pylab from an interactive prompt:

[me@mycomputer ~] $ python
Python 2.5 (r25:51908, Oct 19 2007, 09:47:40)=20
[GCC 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pylab
>>> import matplotlib
>>> import scipy
>>>=20

If I try to run a script which imports pylab I get the following=20
error:

[me@mycomputer ~] $ python scripts/fit_gauss.py
Traceback (most recent call last):
  File "scripts/fit_gauss.py", line 3, in <module>
    from pylab import *
  File "/usr/lib/python2.5/site-packages/pylab.py", line 1, in=20
<module>
    from matplotlib.pylab import *
ImportError: No module named pylab

I am also getting the same error if I try to run a script from XEmacs.

Thank you for your time!

Cheers,

Maximilian

I can't reproduce.  Does the file
"/usr/lib64/python2.4/site-packages/matplotlib/pylab.py" exist for
you?

I'm using the most recent svn (2273), and I can't reproduce this.

Something is flaky.  Try running python with "python -v".  You can
also try the "--verbose-debug-annoying" flag, but I am guessing you
aren't getting far enough to get any matplotlib output.

This sounds like a python path issue. Nils, could it be that you have a 
matplotlib directory in your current working directory? Try changing dirs and 
running your test again.

No but I had a file called matplotlib.py in my home directory. I have 
removed it. Now it works again.
Thank you very much and sorry for the noise !
