A Gradio custom component to help you label text snippets inline

Installation

pip install gradio_textlabeler

Usage

from gradio_textlabeler.textlabeler import TextLabelerData
import gradio as gr
from gradio_textlabeler import TextLabeler


with gr.Blocks() as demo:
    gr.Markdown("Label the tweets as positive, negative, or neutral and click on Submit Labels")
    inp = TextLabeler(
        label="Label these tweets",
        info="Label the tweets as positive, negative, or neutral.",
        label_choices=["Positive", "Negative", "Neutral"],
        value=[
            {"text": "I am extremely mad", "label": "Negative"},
            {
                "text": "This product is the next best thing since sliced bread",
                "label": "Positive",
            },
            {"text": "I don't know how I feel about this", "label": None},
            {"text": "The weather is nice today", "label": None},
            {"text": "I love this song", "label": "Positive"},
            {"text": "I'm not sure what to think", "label": None},
        ],
        allow_duplicate_labels=True,
        unlabelled_value_display="No Label",
        text_column_width="60%",
        text_column_header="Tweet",
        label_column_header="Sentiment",
    )   
    btn = gr.Button("Submit Labels")
    out = TextLabeler(label="Label output example")
   
    btn.click(fn=lambda x:x, inputs=inp, outputs=out)

TextLabeler

Initialization

name	type	default	description
label_choices	list[str] | None	None	None
value	list[LabeledValue] | None	None	Set of text-label pairs in the form of LabeledValues. If a "text" is intentionally not labeled, the "label" should be set to None.
allow_duplicate_labels	bool	False	If True, allows the same label to be used for multiple text entries.
unlabelled_value_display	str	"Unlabeled"	The label to display for text entries that are not labeled.
text_column_header	str	"Text"	The header to display for the text column.
label_column_header	str	"Label"	The header to display for the label column.
text_column_width	str	"60%"	The width of the text column.
label	str | None	None	component name in interface.
info	str | None	None	additional component description.
every	float | None	None	If `value` is a callable, run the function 'every' number of seconds while the client connection is open. Has no effect otherwise. The event can be accessed (e.g. to cancel it) via this component's .load_event attribute.
show_label	bool | None	None	if True, will display the component label.
scale	int | None	None	relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True.
min_width	int	160	minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first.
interactive	bool | None	None	if True, choices in this dropdown will be selectable; if False, selection will be disabled. If not provided, this is inferred based on whether the component is used as an input or output.
visible	bool	True	If False, component will be hidden.
elem_id	str | None	None	An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles.
elem_classes	list[str] | str | None	None	An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles.
render	bool	True	If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later.
key	int | str | None	None	if assigned, will be used to assume identity across a re-render. Components that have the same key across a re-render will have their value preserved.

Events

name	description
change	Triggered when the value of the TextLabeler changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See .input() for a listener that is only triggered by user input.
submit	This listener is triggered when the user presses the Enter key while the TextLabeler is focused.

User function

The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).

• When used as an Input, the component only impacts the input signature of the user function.
• When used as an output, the component only impacts the return signature of the user function.

The code snippet below is accurate in cases where the component is used as both an input and an output.

• As output: Is passed, the preprocessed input data sent to the user's function in the backend.
• As input: Should return, the output data received by the component from the user's function in the backend.

def predict(
    value: TextLabelerData
) -> TextLabelerData:
    return value

LabeledValue

class LabeledValue(BaseModel):
    text: str
    label: str | None

TextLabelerData

class TextLabelerData(GradioRootModel):
    root: List[LabeledValue]
