PyHammer Crash/Does not Run when running example PyHammer script

[thaynecurrie]

I have installed PyHammer and have verified that I have sufficiently updated versions of packages.

Unfortunately, PyHammer crashes and I cannot run it, even when attempting to run the example script provided in the wiki

1. (from command line)
   python pyhammer.py -f -l -i test_case/exampleInputFile.txt

2. the GUI pops up. I click on "Start PyHammer"

3. after two warnings about creating "an ndarray from ragged nested sequence(s)", I get the following crash:

Traceback (most recent call last):
File "pyhammer.py", line 864, in goToMain
main(self.options)
File "pyhammer.py", line 232, in main
Eyecheck(spec, options)
File "/Users/thaynecurrie/Research/Data/stellar/PyHammer/eyecheck.py", line 24, in init
self.updatePlot() # Update the plot showing the template and spectrum
File "/Users/thaynecurrie/Research/Data/stellar/PyHammer/eyecheck.py", line 659, in updatePlot
if self.toolbar._active != 'ZOOM':
AttributeError: 'NavigationToolbar2QT' object has no attribute '_active'
Abort

The crash occurs regardless of whether I run in command line mode (-c), GUI (-g), or full (-f)

This is a duplicate of Issue #40. Essentially, newer versions of matplotlib have depreciated a feature the eyeplot was trying to use. Ideally a fix should be added to the repository, but as a simple fix on your end, try going to Line 659 in eyecheck.py and changing _active to _actions. That should work. At worst, you can just comment out that entire if statement as it's only there as a nice-to-have feature and not critical.

Hope that helps!

Hi, I've just downloaded this very nice tool, I fixed the line 659 in eyecheck.py as you told. Apparently now it works, but as soon as I try to re-size the GUI it crashes as before.
