vistrails ImportError: No module named pylab.plot

[aschilas]

Dear matplot-users,

i have a problem and cannot find a solution. I don't have a lot of experience with python in general and matplotlib.

I want to use a program called vistrails (http://www.vistrails.org) with ALPS (alps.comp-phys.org)
but i think that the problem stems from python.

I installed python from source in my own directory since i don't have superuser access at my pc and build all the neccessary packages from source including scipy numpy and matplotlib.

When trying to import the ALPS module to vistrails i always get the error:

ImportError: No module named pylab.plot

I already tried everything in the troubleshooting and matlibplot seems to work properly when testing.

Here the needed information:

OS: Linux l39 3.2.0-60-generic-pae #91-Ubuntu SMP Wed Feb 19 04:14:56 UTC 2014 i686 i686 i386 GNU/Linux

I am currently using matlibplot 1.1.0 and also tried the newest version 1.3.1 i downloaded the source from http://matplotlib.org and compiled it myself.

I made no changes to setup.py or setupext.py

my compiler is gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

python setup.py build gives:

basedirlist is: ['/usr/local', '/usr']

This is not a matplotlib bug, it is a problem with your vistrails and/or alps installation--maybe just with your PYTHONPATH environment variable after doing those installations. The import error has nothing to do with matplotlib directly. Here is what I see in the alps source archive:

efiring@manini2:~/temp/alps-2.1.1-r6176-src$ grep -r pylab --include '*.py' . | grep import
./alps/vistrails/alps/plots.py:from packages.pylab.plot import MplPlot, MplPlotConfigurationWidget

plots.py is trying to find a pylab.plot module in packages, and it is failing. This is not our code. We don't have a packages, or a pylab.plot module.

Thank you for looking it up.

best wishes Anders

|plots.py| is trying to find a |pylab.plot| module in |packages|, and
it is failing. This is not our code. We don't have a |packages|, or a
|pylab.plot| module.
