Tqdm 4.28.1 in Jupyter Notebook "IntProgress not found. Please update jupyter and ipywidgets."

This worked for me.

conda install -c conda-forge ipywidgetsjupyter nbextension enable --py widgetsnbextension

Restarting jupyter notebook afterwards worked.

Solution originally from here.

python jupyter-notebook tqdm

For those not using conda:

pip3 install ipywidgets --user

python jupyter-notebook tqdm

This works fine for me:

conda install ipywidgets==7.4.2
