Ginga cannot load stginga plugins

[pllim]

@ejeschke , this no longer works. Does this have something to do with ejeschke/ginga#426? Please advise.

$ ginga --loglevel=40 --stderr --plugins=stginga.plugins.DQInspect

Calling stginga directly gives similar traceback.

I don't think it should have anything to do with that PR because it simply added an additional way to load plugins. In other words, I didn't change the existing ways that plugins can be loaded.

I'll give it a try and report my results.

[ejeschke]

I think the ModuleManager did get an update recently, having to do with python 3 compatibility.

Do you get the same result with python 2.7?

[pllim]

Oh, dear. I have not touched Python 2.7 in a while... :sweat_smile: Let me see if I remember where it is...

[pllim]

On Python 2.7 using latest dev of both:

$ ginga --loglevel=40 --stderr --plugins=stginga.plugins.DQInspect

[ejeschke]

@pllim, can you try commit ejeschke/ginga@48348a8d57aa7bbd5aded5a13fd771f36906fd89 ? I think this may fix the issue.

[ejeschke]

It was due to the ModuleManager update.

[pllim]

Thanks for the quick fix, @ejeschke !
