Jupyter Notebook javascript error when trying to display the widgets

I am currently working on a EDA Project using ydata_profiling library.

This is the code i have written as of now:

import numpy as np
import pandas as pd
from ydata_profiling import ProfileReport

profile = ProfileReport(df, title='Pandas Profiling Report', explorative=True)

profile.to_widgets()

On displaying this .to_widgets() code, a summary of my data appears, but under the variables section i get this javascript error:

I would really appreciate some suggestions or fixes for this.

Solution: Please don't overlook updating the version of your jupyter notebook. I updated the entire jupyter notebook environment and reloaded and issue got resolved. Run commands like :

jupyter notebook --version

pip install --upgrade notebook
Solution

  • Jupyter Lab issue displaying widgets (javascript error) received several relevant answers, none of them being a definite answer on its own. This suggests:

    So, first step is making sure the whole environment is up to date, starting with conda, then Jupyter and ipywidgets.

    A couple notes:
