        # 🐦 pigeonXT - Quickly annotate data in Jupyter Lab
        PigeonXT is an extention to the original [Pigeon](https://github.com/agermanidis/pigeon), created by [Anastasis Germanidis](https://pypi.org/user/agermanidis/).
        PigeonXT is a simple widget that lets you quickly annotate a dataset of
        unlabeled examples from the comfort of your Jupyter notebook.
        
        Pigeon 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 :code:`display_fn` argument.
        
        Additionally, custom hooks can be attached to each row update (:code:`example_process_fn`),
        or when the annotating task is complete(:code:`final_process_fn`).
        
        ## Installation
        PigeonXT obviously needs a Jupyter Lab environment. Futhermore, it requires ipywidgets.
        The widget itself can be installed using pip:
        ```bash
            pip install pigeonXT-jupyter
        ```
        
        To run the provided examples in a new environment using Conda:
        ```bash
            conda create --name pigeon python=3.7
            conda activate pigeon
            conda install nodejs
            pip install numpy pandas jupyterlab ipywidgets
            pip install pigeonXT-jupyter
        ```
        
        Starting Jupyter Lab environment:
        ```bash
            jupyter lab
        ```
        
        ## Examples
        Examples are also provided in the accompanying notebook.
        
        ### Binary or multi-class text classification
        Code:
        ```python
            from pigeonXT import annotate
            annotations = annotate(
              ['I love this movie', 'I was really disappointed by the book'],
              options=['positive', 'negative', 'inbetween']
            )
        ```

        ### multi-label text classification
        Code:

            ])
        
            labels = ['Adventure', 'Romance', 'Fantasy', 'Science fiction', 'Horror', 'Thriller']
        
            annotations = annotate( df.title,

        ### Image classification
        Code:
        ```python
            from pigeonXT import annotate
            from IPython.display import display, Image
        
            annotations = annotate(
              ['assets/img_example1.jpg', 'assets/img_example2.jpg'],
              options=['cat', 'dog', 'horse'],
              display_fn=lambda filename: display(Image(filename))
            )
        ```
