Widgets Disappear after 1 or 2 seconds

#1

I am trying to create an extension for jupyter notebook but the extension does not seem to work as expected .
The extension basically loads the widgets on startup of each new notebook .
The issue is the widgets load for a brief second and then disappear .
when i run the cell again the widgets work as expected.

Any suggestions?

We’ll need more information to give you pointers on what you could investigate, such as the version of JLab, is this ipywidgets that you are talking about (if so, what version), and a simple reproducible example would be great.
