[pdfgui bug] I think I broke PDFGui

[dif...@diffpy.org]

summary: I think I broke PDFGui

description: I'm running Ubuntu; a few days ago I tried upgrading from Hardy to Intrepid, and got some error messages related to NumPy. Since then I've removed and completely re-installed NumPy, but to no avail, apparently. The DiffPy website hasn't been working for the last few days, so I've been unable to check and see whether maybe there are other libraries I should be looking at replacing.

This error happened when, immediately after starting PDFgui, I tried creating a new fit. I get errors when I try to do pretty much anything now, which is what makes me think I have a bad library somewhere.

Hi Craig,

There seems to be some problem with the matplotlib library.
Your PDFgui is installed under Python 2.5, but Hardy comes with
Python 2.6 and it is possible that some libraries in the 2.5 tree
stopped working. Please, try to reinstall PDFgui under python 2.6.
Use "python -V" to verify what is your python version and make sure
all system packages required for PDFgui are installed:

sudo aptitude install \
python-wxtools python-numpy python-setuptools \
python-matplotlib python-dev libgsl0-dev g++

sudo easy_install diffpy.pdfgui

Hope this helps,

Pavol

Never mind -- after sending this in I tried re-installing matplotlib; now it works fine.

No problem. BTW, diffpy.org should be up again. We will move
that server from MSU to Columbia soon, so there might be few
more hitches this month. Sorry about that. Cheers,
