[BUG] Specviz: Application not opening! #1676

Open atharvabagul2000 opened 1 year ago

atharvabagul2000 commented 1 year ago

Describe the bug I have been using SpecViz for quite a while, today, I reloaded and had to run my code, but the SpecViz application is not opening.

It is getting imported and showing no error, but the application is not visible. I am getting the following response when I load the application on Jupyter Notebook. I also tried !pip install jdaviz --upgrade and after restarting the kernel I ran SpecViz. It is still showing the same message instead of loading the application.

Application(config='specviz', events=['call_viewer_method', 'close_snackbar_message', 'data_item_remove', 'dat…

Expected behavior When I run the following:

specviz = Specviz() specviz.load_spectrum(...) specviz.app

It should show me the application window in the output section of Jupyter cell.

Desktop (please complete the following information):

Do you still see this problem if you create a new conda environment and only install Jdaviz there?

Do you see any errors in the browser console?

atharvabagul2000 commented 1 year ago

I was not getting this issue till sometime back. This problem just occurred a few days back. I didn't see any issues in the browser console.

Sometimes some upstream update would cause incompatibility that we cannot control. If the problem go away with a new environment, then just use the new environment. 🤞

I am not getting it either in a new environment I created. It is still showing the same issue.

We just released v3.0.1 yesterday. Can you please upgrade again and see? Thanks!

atharvabagul2000 commented 1 year ago

I tried it just now by upgrading it. The issue still persists!

I am not getting enough information here to help you debug. If you wish to Slack call and share your screen, we can try that on Astropy Slack: http://joinslack.astropy.org/

Alas, that is not good for me, but please direct message me (pllim) in that Slack workspace and reference this issue. We can go from there. Thanks!

Update 2022-10-12: We created another fresh enviroment with Python 3.9 and did a pip install jdaviz --upgrade (v3.0.1). We did have to make sure notebook was pointing to the correct conda env. The research notebook in question took a long time to load but investigating that is out of scope. We were able to make Jdaviz application display in a simple notebook but:

So, something in that research notebook is messing up Jdaviz widget application rendering but I don't know what.

Next step: User would provide a more minimal version of the research notebook, just enough to reproduce the problem. Send that along with necessary data to help call. Dev(s) will try to reproduce the problem.

User indicated that separating out just Jdaviz parts into a separate notebook was not a viable solution for the research workflow. User also wants @PatrickOgle to be in the loop on this issue.

PatrickOgle commented 1 year ago

@pllim I have not experienced a similar problem with my version of the notebook in my environment. The notebook is not remarkably 'heavy', and seems typical of astro workflows, similar to a JDAT notebook in scope.

@atharvabagul2000 , another thing you can try is to use Jupyter Lab instead of Jupyter Notebook and see if it makes any difference. Thanks for your patience!
