Description Anthony Horton 2011-11-23 11:28:03 UTC

Description of problem:

There is an incompatibility between the version of NumPy in the Fedora 16 repos and python-numdisplay which prevents numdisplay from working at all.

A bug was filed upstream against numdisplay ( https://www.stsci.edu/trac/ssb/stsci_python/ticket/694 ) and a trivial fix applied to the development tree ( https://www.stsci.edu/trac/ssb/stsci_python/changeset/12315 ) however there have been no new upstream releases of numdisplay containing the fix.  The fix was added as version 1.6.1 but the last released version of numdisplay ( http://stsdas.stsci.edu/numdisplay/ ) is version 1.5.6.

Can this trivial fix be back-ported to the Fedora python-numdisplay package?  Numdisplay is completely unusable without it.


Version-Release number of selected component (if applicable):

python-numdisplay 1.5.6-3.fc15 
numpy.x86_64 1:1.6.0-2.1.fc16 


How reproducible: Always


Steps to Reproduce:
1. Call the numdisplay.display() method from within Python code/interpreter

  
Actual results:

A TypeError exception.  See full trace back under additional info below.


Expected results:

NumPy array is displayed in ds9 application.


Additional info:

In [27]: a = numpy.array([[2,1],[1,0]])

In [28]: numdisplay.display(a)
