This also works for me. Remember to restart the kernel :)

i just restarted the kernel and it helped.

[Grazys]

I went to cmd as administrator and put pip install nbformat and it worked

[Grazys]

Or, if you need to upgrade de nbformat, you need to put pip install --upgrade nbformat

I installed nbformat and that fixed the error in the original post, but ran into a subsequent problem.

Running

import plotly.io as pio
pio.renderers.default = "notebook_connected+pdf"

I got AttributeError: module 'isoduration' has no attribute 'DurationParsingException'. Full trace:

That error was misleading, as isoduration wasn't installed. Fixed by installing isoduration, which is apparently a transitive dependency of nbformat->jsonschema. It's still unclear to me where that need is coming from. I'm also having trouble reproducing when creating an environment from scratch. Sharing in case any else runs into the same issue.

Restart your vscode or juypyter notebook
