Jupyter and Ipywidgets up to date, yet ImportError: IntProgress not found. Please update jupyter and ipywidgets.

Hello,

I have been getting this error when trying to use Tpot library in a jupyter notebook.

tpot.TPOTClassifier.fit(x_train, y_train)

Warning: xgboost.XGBClassifier is not available and will not be used by TPOT.

During handling of the above exception, another exception occurred:

ImportError: IntProgress not found. Please update jupyter and ipywidgets. See https://ipywidgets.readthedocs.io/en/stable/user_install.html

I have followed the ipywidgets installation instructions (https://ipywidgets.readthedocs.io/en/stable/user_install.html), updated conda, but despite all the effort this problem still remains.

The jupyter version:

jupyter core     : 4.5.0
jupyter-notebook : 6.0.0
qtconsole        : 4.5.2
ipython          : 7.6.1
ipykernel        : 5.1.1
jupyter client   : 5.3.1
jupyter lab      : 1.0.4
nbconvert        : 5.5.0
ipywidgets       : 7.5.1
nbformat         : 4.4.0
traitlets        : 4.3.2

Thank you in advance for any suggestions how to get around this!

Hi! Thanks for commenting! This is exactly why I was raising the issue in the first place. Check my jupyter version against the current changelogs. All seems to be up to date. Even though I can import the IntProgress, it still returns the error…

Have you been able to resolve this issue? 😃

I face the exact same problem.

pip install --upgrade jupyter_client resolved this problem for me.

And you can double-check that ipywidgets is working fine by trying to import that yourself:

from ipywidgets import IntProgress
