I was running a simple sine wave generator program using widgets with interact command on a Mint 18.3. Perfect! The program commences with
Blockquote
%matplotlib inline
import matplotlib.pyplot as plt
import numpy as np
from ipywidgets import interact
Blockquote
Now I have installed a fresh Mint 20, and Jupyter Notebook, Using the same program I get the following message:
Blockquote
Widget Javascript not detected. It may not be installed or enabled properly.
Blockquote
When I operate the widgets, I get:
Blockquote
The save operation succeeded, but the notebook does not appear to be valid. The validation error was:
Notebook validation failed: {‘model_id’: ‘7196c42ed6f441279205c0eb24207f99’} is not valid under any of the given schemas:
{
“model_id”: “7196c42ed6f441279205c0eb24207f99”
}
Blockquote
Can you help me to get this set up again correctly, please.
Thanks,
Robin
