ImportError: IProgress not found. Please update jupyter and ipywidgets although it is installed

I am using jupyter notebook and installed

ipywidgets==7.4.2 widgetsnbextension pandas-profiling=='.0.0 

and also I ran:

!jupyter nbextension enable --py widgetsnbextension 

but when runninhg

from pandas_profiling import ProfileReport profile = ProfileReport(df, title="Pandas Profiling Report", explorative=True) profile.to_widgets() 

I get the error:

ImportError: IProgress not found. Please update jupyter and ipywidgets. See 

Any idea why? Tried proposed solutions.

I tried everything you mentioned in a new environment using conda and I had another issue related to the version of ipywidgets (a bug found in Github with comments saying that got solved after using last version). I solved the problem I had installing last version of ipywidgets. Here is my process:

1. Create a new environment using conda (I use miniconda):

conda create --name teststackoverflow python=3.7 

2. Activate new environment:

conda activate teststackoverflow 

3. Install jupyter:

pip install jupyter 

4. Install all the libraries without specific versions to get the last ones:

pip install ipywidgets widgetsnbextension pandas-profiling 

5. Run jupyter notebook in the console to turn on the notebooks server and create a new notebook.
6. Run this line in a new cell:

!jupyter nbextension enable --py widgetsnbextension 

With the result:

Enabling notebook extension jupyter-js-widgets/extension... - Validating: OK 

7. Run some sample code to define df:

import pandas as pd df = pd.DataFrame({'A': [1, 2, 3, 4], 'B': [1, 2, 3, 4]}) 

8. Run the code you provided:

from pandas_profiling import ProfileReport profile = ProfileReport(df, title="Pandas Profiling Report", explorative=True) profile.to_widgets() 

Final output looks good:

this had worked for me (for all of you who prefer pip instead of conda..) in your virtualenv run

pip install ipywidgets jupyter nbextension enable --py widgetsnbextension 

or, if you prefer to run it in your notebook

!pip install ipywidgets !jupyter nbextension enable --py widgetsnbextension 

and in your notebook add

from ipywidgets import FloatProgress 

Installing ipywidgets and building Jupyter Lab did the trick for me.

0. Make sure you activate the correct conda environment
1. Install ipywidgets: conda install -c conda-forge ipywidgets
2. To build Jupyter Lab, you need to have nodejs > 12.0.0 installed. Check the latest version number from Anaconda website and install nodejs specifying the package number e.g. conda install -c conda-forge nodejs=16.6.1
3. Stop Jupyter Lab
4. Build Juyter Lab: jupyter lab build
5. Start Jupyter Lab

I ran into the same error within the jupyter lab and I just installed ipywidgets using conda install -c conda-forge ipywidgets command.
