PigeonXT is an extention to the original Pigeon, created by Anastasis Germanidis. PigeonXT is a simple widget that lets you quickly annotate a dataset of unlabeled examples from the comfort of your Jupyter notebook.
PigeonXT currently support the following annotation tasks:
- binary / multi-class classification
- multi-label classification
- regression tasks
- captioning tasks
Anything that can be displayed on Jupyter
(text, images, audio, graphs, etc.) can be displayed by pigeon
by providing the appropriate display_fn
argument.
Additionally, custom hooks can be attached to each row update (example_process_fn
),
or when the annotating task is complete(final_process_fn
).
There is a full blog post on the usage of PigeonXT on Towards Data Science.

PigeonXT obviously needs a Jupyter Lab environment. Futhermore, it requires ipywidgets. The widget itself can be installed using pip:
pip install pigeonXT-jupyter
Currently, it is much easier to install due to Jupyterlab 3: To run the provided examples in a new environment using Conda:
conda create --name pigeon python=3.9
conda activate pigeon
pip install numpy pandas jupyterlab ipywidgets pigeonXT-jupyter
For an older Jupyterlab or any other trouble, please try the old method:
conda create --name pigeon python=3.7
conda activate pigeon
conda install nodejs
pip install numpy pandas jupyterlab ipywidgets
jupyter nbextension enable --py widgetsnbextension
jupyter labextension install @jupyter-widgets/jupyterlab-manager
pip install pigeonXT-jupyter
Starting Jupyter Lab environment:
jupyter lab
I have moved the development environment to Poetry. To create an identical environment use:
conda env create -f environment.yml
conda activate pigeonxt
poetry install
pre-commit install
Examples are also provided in the accompanying notebook.
