Notebook validation failed

See original GitHub issue

I am using jupyter 1.0.0 and ipywidgets 6.0.0 on Python3 and when I try to save my notebook after calling the display() function from IPython.display I get the following message:

Notebook validation failed: {‘model_id’: ‘211cc089c9134af79f0a8ccff7244ae8’} is not valid under any of the given schemas: { “model_id”: “211cc089c9134af79f0a8ccff7244ae8” }

Example code that gives the error: from ipywidgets import FloatProgress from IPython.display import display a = FloatProgress(value=7.5,min=0,max=10.0) display(a) If I remove the call display(a) and save the file it raises no error.

I found a solution to my problem:

From https://github.com/jupyter/nbformat/issues/161#issuecomment-574530127, by updating manually the "nb_format_minor": 1 to "nb_format_minor": 4 the problem disappears.

This is a bug that occurs with nbformat < 4.2. If you update nbformat, this should go away.
