backend for matplotlib on NAS Lou

Hi all,

I'm just getting started with running hydro calculations on NASA's Pleiades
cluster. To view the results one can use the Lou nodes (dedicated to data
analysis). I installed anaconda so that I could use matplotlib, but so far
I can't find a backend that works. Qt5Agg leads to an error from
libpthread about the GLIBC version. Qt4 fails with "No module named
PyQt4". Anyway, does anyone have a solution to this?

Of course, I could ask this of the NAS folks, but I thought it was likely
that someone on this list had dealt with this problem.

Regards,
Jon

Since you are a professional in astro-whatever, I *might* susepct that
you loaded in your computer a good deal of specific software.
I did that once, when I taught something the local folks name
"informatique g?ographique".? Not knowing what I would really use, I fed
the beast with at least 5 different GIS, and some other stuff, some of
which came with their private copies of QT and PyQT. And there were
conflicts...
A thorough cleaning, elimination of double packages, isolating the
environments, and ensuring that when I use Anaconda Matplotlib packages,
its support is searched for first, really helped, not only me and my
students, but some friends (local physicists) as well. No guarantee,
though...

Best regards

On my desktop I installed Anaconda last fall - so it's pretty recent. I
also needed PyQt4. If that would solve your problem, here's one answer:

Read thru and you will find "conda install pyqt=4".
