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

Question

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 running:
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 https://ipywidgets.readthedocs.io/en/stable/user_install.html
Any idea why?
Tried proposed solutions.

Answer 1

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:
Create a new environment using conda (I use miniconda):
conda create --name teststackoverflow python=3.7
Activate new environment:
conda activate teststackoverflow
Install jupyter:
pip install jupyter
Install all the libraries without specific versions to get the last ones:
pip install ipywidgets widgetsnbextension pandas-profiling
Run jupyter notebook in the console to turn on the notebooks server and create a new notebook.
Run this line in a new cell:
!jupyter nbextension enable --py widgetsnbextension
With the result:
Enabling notebook extension jupyter-js-widgets/extension...
- Validating: OK
Run some sample code to define df:
import pandas as pd
df = pd.DataFrame({'A': [1, 2, 3, 4], 'B': [1, 2, 3, 4]})
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:

Answer 2

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

Answer 3

Installing ipywidgets and building Jupyter Lab did the trick for me.
Make sure you activate the correct conda environment
Install ipywidgets: conda install -c conda-forge ipywidgets
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
Stop Jupyter Lab
Build Juyter Lab: jupyter lab build
Start Jupyter Lab

Answer 4

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

Answer 5

I ran into the same error. On M1 mac, I change from tqdm.notebook import tqdm as tqdm to from tqdm import tqdm. Hope it helps. Original post: https://github.com/CosmiQ/solaris/issues/392#issuecomment-759238485
