Crashes while processing .fits file

[jvntra]

While attempting to process one spectrum, I got some errors which are pasted below:

1) Processing spec-0473-51929-0157.fits Exception in Tkinter callback Traceback (most recent call last): File "/Users/JPeg/anaconda/envs/solarium3.5/lib/python3.5/site-packages/matplotlib/backends/tkagg.py", line 22, in blit id(data), colormode, id(bbox_array)) _tkinter.TclError: invalid command name "PyAggImagePhoto"

During handling of the above exception, another exception occurred:

We cannot reproduce the issue by running on the same spectrum. Can you post your current operating system (and version), python version, matplotlib version, and tkinter version?

Hello,

I'm using Mac OS X 10.11.5, Python 3.5.2 :: Anaconda 4.1.1 (x86_64) , Matplotlib 1.5.1, tk 8.5.18

However, i was able to fix my issues by changing "TkAgg" in eyecheck.py to "Qt4Agg".

We previously used the TkAgg backend by default for Macs as that appeared to work for every case we tried. It seems your particular setup doesn't work. We're going to try switching to the Qt4Agg backend for macs by default. Please let us know if this causes any further problems.
