Question

How to fix the tqdm warning: "IProgress not found" in Jupyter (missing ipywidgets)?

Decision Rationale

The specific Jupyter warning about tqdm rendering and missing ipywidgets is not present in the existing FAQs, and it’s a notebook/Jupyter tooling issue that fits under this course’s miscellaneous environment support.

This warning occurs when tqdm tries to display an interactive progress bar in Jupyter Notebook or JupyterLab, but the required ipywidgets package is missing, outdated, or not correctly enabled.

Recommended fix: Install ipywidgets
If you're using pip, run:
python -m pip install --upgrade ipywidgets tqdm

If you're using uv:
uv add ipywidgets tqdm

If you're using Conda:
conda install -c conda-forge ipywidgets tqdm

Important: Install ipywidgets in the Python environment used by your Jupyter notebook kernel, not necessarily the environment used by your terminal.

You can check the kernel's Python executable inside a notebook:

import sys
print(sys.executable)

Or install directly into the active notebook kernel using:
%pip install --upgrade ipywidgets tqdm

After installation, restart the Jupyter kernel and refresh the notebook page if necessary.
