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

Question

I am trying to use tqdm_notebook in my Python code, but I am running into this error

import tqdm

for i in tqdm.tqdm_notebook(range(2, int(total_number)//20):i

ERROR:

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

I am using Python 3.7.1 and tqdm version (4.28.1)

Solution 1

This worked for me.

conda install -c conda-forge ipywidgets
jupyter nbextension enable --py widgetsnbextension

Restarting jupyter notebook afterwards worked.

Solution originally from here.

Solution 2

For those not using conda:

pip3 install ipywidgets --user

Solution 3

This works fine for me:

conda install ipywidgets==7.4.2

Solution 4

ah my bad ! Just had to install the packages jupyter and ipywidgets!
