odd crash, apparently unicode-related.

[mperrin]

Twice just now I've had the CTVT crash and die for no apparent reason. The crashes occurred once when I was clicking in the window to position the companion at a given roll angle, and once when I clicked on the 'zoom to fit' button.

The error traceback is pretty unhelpful:

    self.tk.mainloop(n)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

This is on an iMac running Sierra, Python 3.5, tinter 0.3.1, with a pretty standard astroconda setup.

That... should be fixed? Make sure you have the latest versions of everything? The version of Tk bundled with anaconda was incompatible with Python3 due to a lack of support for mouse scroll events which was fixed at some point. I think.

@juliengirard is it possible this is the crash you were seeing?

[mperrin]

@kjbrooks possible this is the crash you just saw?

[kjbrooks]

Yes, this is the crash I saw.

[juliengirard]

Since I restarted to use the CVT in 2019, I haven't experienced any crash, have you?

[kjbrooks]

@juliengirard how are you running this? I barely remember doing this and when I tried to run it today, I got an error. It wasn't the same error as the one that Marshall posted above though.

[juliengirard]

@kjbrooks in this case I use the MacOS app https://jwst-docs.stsci.edu/other-tools/target-visibility-tools/jwst-coronagraphic-visibility-tool-help

If you're running macOS and want a double-clickable app:

Download the double-clickable app archive (e.g. jwst_coronagraph_visibility_calculator_macos_v0.1.0.zip) from https://github.com/spacetelescope/jwst_coronagraph_visibility/releases/latest
Extract the .zip file to get the .app bundle
Double-click the .app bundle

[kjbrooks]

@juliengirard I cannot get the app to work for me. I double click on it but nothing happens. And, if I try running it from the command line with the jwst-coronagraph-visibility-gui command, I get the following error:

    from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
ImportError: cannot import name 'NavigationToolbar2TkAgg'

I fully recognize that this is probably an issue on my end at this point. If others can get it working, I am happy to have this issue closed and to sit down with you at some point to troubleshoot why it isn't working for me. (I also don't use this tool, really, ever, so I'm not sure if it even matters).

[juliengirard]

It used to work in command line but not anymore...

On python 3.5, I get

`

On python 2.7, I have issues with Tkinter

The CVT gui is still crashing with Unicode errors in python 3.5. This happens sometimes when
clicking the plot windows or the magnify tool:
