[BUG] Confusing error message on aperture photometry tab when photutils is not installed

[eteq]

Jdaviz component

Imviz

Description

I created a fresh environment to test something in jdaviz, but I forgot to install photutils. Then when I tried to open up the aperture photometry plugin, I get the following rather misleading error:

The confusing thing being the "No data available", when, as the screenshot shows, there's clearly data. If I re-do it with photutils installed it correctly shows the data sets present.

How to Reproduce

1. Install jdaviz but not photutils
2. Start imviz, load some image
3. Open the aperture photometry plugin

Expected behavior

I would have expected some sort of "photutils not installed" message in the plugin.

How did you even get to the point of having jdaviz without photutils? photutils is a required dependency.

jdaviz/pyproject.toml

Line 28 in d033439

"photutils>=1.4",

Not sure if there is anything we can do to help you if you managed to circumvent pip install rules.

Also your version manifest above says you have photutils 1.8.0

Aperture requires a subset to exist. We don't set the "No data available text", but I can see how that is very misleading, perhaps we can try to override it. Or if there are no values, instead of showing the dropdown, show a warning alert in its place.

I don't think you can even import jdaviz without photutils, although we could do what we do for footprints and allow importing and just disable the plugin (with a warning in the UI).

I really don't think there is anything to fix here. It was likely user error. I asked Erik to close this issue if he cannot reproduce it.
