MeqTrees Ubuntu 8.10 Release Notes

Ubuntu 8.10 ships a slightly broken matplotlib package. This is not required for core functionality, but does affect:

  • rendering of FITS images in Purr logs

  • the pylab plotter (used in Jan Noordam's experimental visualization trees.) You will see the following warning on startup caused by a broken matplotlib:

Welcome to the MeqTrees Browser! Please wait a second while the GUI starts up. Module dateutil was already imported from /var/lib/python-support/python2.5/dateutil/init.py, but /var/lib/python-support/python2.5 is being added to sys.path matplotlib (aka pylab) package not found, rendering of FITS histograms will not be available. matplotlib is available from http://matplotlib.sourceforge.net/, or as Debian package python-matplotlib.

*** matplotlib/pylab not imported! *** The system will assume that matplotlib is not present.

The problem can be fixed as follows: 

* install the python-tk package 
* start the meqbrowser as root - you only need to do this once 
* ```
sudo meqbrowser
