Version 3.37

New Features:

Introducing a new gr.ChatInterface abstraction, which allows Gradio users to build fully functioning Chat interfaces very easily. The only required parameter is a chat function fn, which accepts a (string) user input message and a (list of lists) chat history and returns a (string) response. Here's a toy example:

import gradio as gr

def echo(message, history):
    return message

demo = gr.ChatInterface(fn=echo, examples=["hello", "hola", "merhaba"], title="Echo Bot")
demo.launch()

Which produces:

image

And a corresponding easy-to-use API at /chat:

image

The gr.ChatInterface abstraction works nicely with various LLM libraries, such as langchain. See the dedicated guide for more examples using gr.ChatInterface. Collective team effort in PR 4869

  • Chatbot messages now show hyperlinks to download files uploaded to gr.Chatbot() by @dawoodkhan82 in PR 4848
  • Cached examples now work with generators and async generators by @abidlabs in PR 4927
  • Add RTL support to gr.Markdown, gr.Chatbot, gr.Textbox (via the rtl boolean parameter) and text-alignment to gr.Textbox(via the string text_align parameter) by @abidlabs in PR 4933

Examples of usage:

with gr.Blocks() as demo:   
    gr.Textbox(interactive=True, text_align="right")
demo.launch()

with gr.Blocks() as demo:   
    gr.Markdown("سلام", rtl=True)
demo.launch()

Bug Fixes:

  • The .change() event is fixed in Video and Image so that it only fires once by @abidlabs in PR 4793
  • The .change() event is fixed in Audio so that fires when the component value is programmatically updated by @abidlabs in PR 4793
  • Add missing display: flex property to Row so that flex styling is applied to children by [@hannahblair] in PR 4896

  • Fixed broken image link in auto-generated app.py from ThemeClass.push_to_hub by @deepkyu in PR 4944

Other Changes:

  • Warning on mobile that if a user leaves the tab, websocket connection may break. On broken connection, tries to rejoin queue and displays error conveying connection broke. By @aliabid94 in PR 4742
  • Remove blocking network calls made before the local URL gets printed - these slow down the display of the local URL, especially when no internet is available. @aliabid94 in PR 4905.
  • Pinned dependencies to major versions to reduce the likelihood of a broken gradio due to changes in downstream dependencies by @abidlabs in PR 4885
  • Queue max_size defaults to parent Blocks max_thread when running on Spaces with ZeroGPU hardware. By @cbensimon in PR 4937

Breaking Changes:

Motivated by the release of pydantic==2.0, which included breaking changes that broke a large number of Gradio apps, we've pinned many gradio dependencies. Note that pinned dependencies can cause downstream conflicts, so this may be a breaking change. That being said, we've kept the pins pretty loose, and we're expecting change to be better for the long-term stability of Gradio apps.

    img = gr.Image()
    img_section = gr.AnnotatedImage()
    def mask(img):
        top_left_corner = [0, 0, 20, 20]

Version 3.21.0

New Features:

Theme Sharing 🎨 🤝

You can now share your gradio themes with the world!

After creating a theme, you can upload it to the HuggingFace Hub to let others view it, use it, and build off of it!

Uploading

There are two ways to upload a theme, via the theme class instance or the command line.

  1. Via the class instance
my_theme.push_to_hub(repo_name="my_theme",
                     version="0.2.0",
                     hf_token="...")
  1. Via the command line

First save the theme to disk

my_theme.dump(filename="my_theme.json")

Then use the upload_theme command:

upload_theme\
"my_theme.json"\
"my_theme"\
"0.2.0"\
"<hf-token>"

The version must be a valid semantic version string.

This creates a space on the huggingface hub to host the theme files and show potential users a preview of your theme.

An example theme space is here: https://huggingface.co/spaces/freddyaboulton/dracula_revamped

Downloading

To use a theme from the hub, use the from_hub method on the ThemeClass and pass it to your app:

my_theme = gr.Theme.from_hub("freddyaboulton/my_theme")

with gr.Blocks(theme=my_theme) as demo:
    ....

You can also pass the theme string directly to Blocks or Interface (gr.Blocks(theme="freddyaboulton/my_theme"))

You can pin your app to an upstream theme version by using semantic versioning expressions.

For example, the following would ensure the theme we load from the my_theme repo was between versions 0.1.0 and 0.2.0:

with gr.Blocks(theme="freddyaboulton/my_theme@>=0.1.0,<0.2.0") as demo:
    ....

by @freddyaboulton in PR 3428

Code component 🦾

New code component allows you to enter, edit and display code with full syntax highlighting by @pngwn in PR 3421

The Chatbot component now supports audio, video, and images

The Chatbot component now supports audio, video, and images with a simple syntax: simply pass in a tuple with the URL or filepath (the second optional element of the tuple is alt text), and the image/audio/video will be displayed:

gr.Chatbot([
    (("driving.mp4",), "cool video"),
    (("cantina.wav",), "cool audio"),
    (("lion.jpg", "A lion"), "cool pic"),
]).style(height=800)
image

Note: images were previously supported via Markdown syntax and that is still supported for backwards compatibility. By @dawoodkhan82 in PR 3413

  • Allow consecutive function triggers with .then and .success by @aliabid94 in PR 3430

  • New code component allows you to enter, edit and display code with full syntax highlighting by @pngwn in PR 3421

  • Added the .select() event listener, which also includes event data that can be passed as an argument to a function with type hint gr.SelectData. The following components support the .select() event listener: Chatbot, CheckboxGroup, Dataframe, Dropdown, File, Gallery, HighlightedText, Label, Radio, TabItem, Tab, Textbox. Example usage:
import gradio as gr

with gr.Blocks() as demo:
    gallery = gr.Gallery(["images/1.jpg", "images/2.jpg", "images/3.jpg"])
    selected_index = gr.Textbox()

    def on_select(evt: gr.SelectData):
        return evt.index

    gallery.select(on_select, None, selected_index)

By @aliabid94 in PR 3399

Bug Fixes:

  • Use huggingface_hub to send telemetry on interface and blocks; eventually to replace segment by @dawoodkhan82 in PR 3342
  • Ensure load events created by components (randomize for slider, callable values) are never queued unless every is passed by @freddyaboulton in PR 3391
  • Prevent in-place updates of generic_update by shallow copying by @gitgithan in PR 3405 to fix #3282

Version 3.19.0

New Features:

Improved embedding experience

When embedding a spaces-hosted gradio app as a web component, you now get an improved UI linking back to the original space, better error handling and more intelligent load performance. No changes are required to your code to benefit from this enhanced experience; simply upgrade your gradio SDK to the latest version.

This behaviour is configurable. You can disable the info panel at the bottom by passing info="false". You can disable the container entirely by passing container="false".

Error statuses are reported in the UI with an easy way for end-users to report problems to the original space author via the community tab of that Hugginface space:

By default, gradio apps are lazy loaded, vastly improving performance when there are several demos on the page. Metadata is loaded ahead of time, but the space will only be loaded and rendered when it is in view.

This behaviour is configurable. You can pass eager="true" to load and render the space regardless of whether or not it is currently on the screen.

Version 3.13.0

New Features:

Scatter plot component

It is now possible to create a scatter plot natively in Gradio!

The gr.ScatterPlot component accepts a pandas dataframe and some optional configuration parameters and will automatically create a plot for you!

This is the first of many native plotting components in Gradio!

For an example of how to use gr.ScatterPlot see below:

import gradio as gr
from vega_datasets import data

cars = data.cars()

with gr.Blocks() as demo:
    gr.ScatterPlot(show_label=False,
                   value=cars,
                   x="Horsepower",
                   y="Miles_per_Gallon",
                   color="Origin",
                   tooltip="Name",
                   title="Car Data",
                   y_title="Miles per Gallon",
                   color_legend_title="Origin of Car").style(container=False)

demo.launch()

By @freddyaboulton in PR 2764

Support for altair plots

The Plot component can now accept altair plots as values! Simply return an altair plot from your event listener and gradio will display it in the front-end. See the example below:

import gradio as gr
import altair as alt
from vega_datasets import data

cars = data.cars()
chart = (
    alt.Chart(cars)
    .mark_point()
    .encode(
        x="Horsepower",
        y="Miles_per_Gallon",
        color="Origin",
    )
)

with gr.Blocks() as demo:
    gr.Plot(value=chart)
demo.launch()
image

By @freddyaboulton in PR 2741

Set the background color of a Label component

The Label component now accepts a color argument by @freddyaboulton in PR 2736. The color argument should either be a valid css color name or hexadecimal string. You can update the color with gr.Label.update!

This lets you create Alert and Warning boxes with the Label component. See below:

import gradio as gr
import random

def update_color(value):
    if value < 0:
        # This is bad so use red
        return "#FF0000"
    elif 0 <= value <= 20:
        # Ok but pay attention (use orange)
        return "#ff9966"
    else:
        # Nothing to worry about
        return None

def update_value():
    choice = random.choice(['good', 'bad', 'so-so'])
    color = update_color(choice)
    return gr.Label.update(value=choice, color=color)


with gr.Blocks() as demo:
    label = gr.Label(value=-10)
    demo.load(lambda: update_value(), inputs=None, outputs=[label], every=1)
demo.queue().launch()

Version 3.12.0

New Features:

The Chatbot component now supports a subset of Markdown (including bold, italics, code, images)

You can now pass in some Markdown to the Chatbot component and it will show up, meaning that you can pass in images as well! by @abidlabs in PR 2731

Here's a simple example that references a local image lion.jpg that is in the same folder as the Python script:

import gradio as gr

with gr.Blocks() as demo:
    gr.Chatbot([("hi", "hello **abubakar**"), ("![](/file=lion.jpg)", "cool pic")])

demo.launch()

Alt text

To see a more realistic example, see the new demo /demo/chatbot_multimodal/run.py.

Latex support

Added mathtext (a subset of latex) support to gr.Markdown. Added by @kashif and @aliabid94 in PR 2696.

Example of how it can be used:

gr.Markdown(
    r"""
    # Hello World! $\frac{\sqrt{x + y}}{4}$ is today's lesson.
    """)

Update Accordion properties from the backend

You can now update the Accordion label and open status with gr.Accordion.update by @freddyaboulton in PR 2690

import gradio as gr

with gr.Blocks() as demo:
    with gr.Accordion(label="Open for greeting", open=False) as accordion:
        gr.Textbox("Hello!")
    open_btn = gr.Button(value="Open Accordion")
    close_btn = gr.Button(value="Close Accordion")
    open_btn.click(
        lambda: gr.Accordion.update(open=True, label="Open Accordion"),
        inputs=None,
        outputs=[accordion],
    )
    close_btn.click(
        lambda: gr.Accordion.update(open=False, label="Closed Accordion"),

New Features:

Upload Button

There is now a new component called the UploadButton which is a file upload component but in button form! You can also specify what file types it should accept in the form of a list (ex: image, video, audio, text, or generic file). Added by @dawoodkhan82 in PR 2591.

Example of how it can be used:

import gradio as gr

def upload_file(files):
    file_paths = [file.name for file in files]
    return file_paths

with gr.Blocks() as demo:
    file_output = gr.File()

Accessing the Requests Object Directly

You can now access the Request object directly in your Python function by @abidlabs in PR 2641. This means that you can access request headers, the client IP address, and so on. In order to use it, add a parameter to your function and set its type hint to be gr.Request. Here's a simple example:

import gradio as gr

def echo(name, request: gr.Request):
    if request:
        print("Request headers dictionary:", request.headers)
        print("IP address:", request.client.host)
    return name

io = gr.Interface(echo, "textbox", "textbox").launch()

New Features:

Running Events Continuously

Gradio now supports the ability to run an event continuously on a fixed schedule. To use this feature, pass every=# of seconds to the event definition. This will run the event every given number of seconds!

This can be used to:

  • Create live visualizations that show the most up to date data
  • Refresh the state of the frontend automatically in response to changes in the backend

Here is an example of a live plot that refreshes every half second:

import math
import gradio as gr
import plotly.express as px
import numpy as np


plot_end = 2 * math.pi


def get_plot(period=1):
    global plot_end
    x = np.arange(plot_end - 2 * math.pi, plot_end, 0.02)
    y = np.sin(2*math.pi*period * x)
    fig = px.line(x=x, y=y)
    plot_end += 2 * math.pi
    return fig


with gr.Blocks() as demo:
    with gr.Row():
        with gr.Column():
            gr.Markdown("Change the value of the slider to automatically update the plot")
            period = gr.Slider(label="Period of plot", value=1, minimum=0, maximum=10, step=1)
            plot = gr.Plot(label="Plot (updates every half second)")

Version 3.7

New Features:

Batched Functions

Gradio now supports the ability to pass batched functions. Batched functions are just functions which take in a list of inputs and return a list of predictions.

For example, here is a batched function that takes in two lists of inputs (a list of words and a list of ints), and returns a list of trimmed words as output:

import time

def trim_words(words, lens):
    trimmed_words = []
    time.sleep(5)
    for w, l in zip(words, lens):
        trimmed_words.append(w[:l])
    return [trimmed_words]

The advantage of using batched functions is that if you enable queuing, the Gradio server can automatically batch incoming requests and process them in parallel, potentially speeding up your demo. Here's what the Gradio code looks like (notice the batch=True and max_batch_size=16 -- both of these parameters can be passed into event triggers or into the Interface class)

import gradio as gr

with gr.Blocks() as demo:
    with gr.Row():
        word = gr.Textbox(label="word", value="abc")
        leng = gr.Number(label="leng", precision=0, value=1)
        output = gr.Textbox(label="Output")
    with gr.Row():
        run = gr.Button()

    event = run.click(trim_words, [word, leng], output, batch=True, max_batch_size=16)

demo.queue()
demo.launch()

In the example above, 16 requests could be processed in parallel (for a total inference time of 5 seconds), instead of each request being processed separately (for a total inference time of 80 seconds).

Upload Event

Video, Audio, Image, and File components now support a upload() event that is triggered when a user uploads a file into any of these components.

Example usage:

import gradio as gr

with gr.Blocks() as demo:
    with gr.Row():
        input_video = gr.Video()
        output_video = gr.Video()

     # Clears the output video when an input video is uploaded
    input_video.upload(lambda : None, None, output_video)

Version 3.6

New Features:

Cancelling Running Events

Running events can be cancelled when other events are triggered! To test this feature, pass the cancels parameter to the event listener. For this feature to work, the queue must be enabled.

cancel_on_change_rl

Code:

import time
import gradio as gr

def fake_diffusion(steps):
    for i in range(steps):
        time.sleep(1)
        yield str(i)

def long_prediction(*args, **kwargs):
    time.sleep(10)
    return 42


with gr.Blocks() as demo:
    with gr.Row():
        with gr.Column():
            n = gr.Slider(1, 10, value=9, step=1, label="Number Steps")
            run = gr.Button()
            output = gr.Textbox(label="Iterative Output")
            stop = gr.Button(value="Stop Iterating")
        with gr.Column():
            prediction = gr.Number(label="Expensive Calculation")
            run_pred = gr.Button(value="Run Expensive Calculation")
        with gr.Column():
            cancel_on_change = gr.Textbox(label="Cancel Iteration and Expensive Calculation on Change")

    click_event = run.click(fake_diffusion, n, output)
    stop.click(fn=None, inputs=None, outputs=None, cancels=[click_event])
    pred_event = run_pred.click(fn=long_prediction, inputs=None, outputs=prediction)

    cancel_on_change.change(None, None, None, cancels=[click_event, pred_event])


demo.queue(concurrency_count=1, max_size=20).launch()

For interfaces, a stop button will be added automatically if the function uses a yield statement.

Version 3.4

New Features:

1. Gallery Captions 🖼️

You can now pass captions to images in the Gallery component. To do so you need to pass a {List} of (image, {str} caption) tuples. This is optional and the component also accepts just a list of the images.

Here's an example:

import gradio as gr

images_with_captions = [
    ("https://images.unsplash.com/photo-1551969014-7d2c4cddf0b6", "Cheetah by David Groves"),
    ("https://images.unsplash.com/photo-1546182990-dffeafbe841d", "Lion by Francesco"),
    ("https://images.unsplash.com/photo-1561731216-c3a4d99437d5", "Tiger by Mike Marrah")
    ]

with gr.Blocks() as demo:
    gr.Gallery(value=images_with_captions)

demo.launch()
gallery_captions

2. Type Values into the Slider 🔢

You can now type values directly on the Slider component! Here's what it looks like:

type-slider

3. Better Sketching and Inpainting 🎨

We've made a lot of changes to our Image component so that it can support better sketching and inpainting.

Now supports:

  • A standalone black-and-white sketch
import gradio as gr
demo = gr.Interface(lambda x: x, gr.Sketchpad(), gr.Image())
demo.launch()

bw

  • A standalone color sketch
import gradio as gr
demo = gr.Interface(lambda x: x, gr.Paint(), gr.Image())
demo.launch()

color-sketch

  • An uploadable image with black-and-white or color sketching
import gradio as gr
demo = gr.Interface(lambda x: x, gr.Image(source='upload', tool='color-sketch'), gr.Image()) # for black and white, tool = 'sketch'
demo.launch()

sketch-new

  • Webcam with black-and-white or color sketching
import gradio as gr
demo = gr.Interface(lambda x: x, gr.Image(source='webcam', tool='color-sketch'), gr.Image()) # for black and white, tool = 'sketch'
demo.launch()

Version 3.3

New Features:

1. Iterative Outputs ⏳

You can now create an iterative output simply by having your function return a generator!

Here's (part of) an example that was used to generate the interface below it. See full code.

def predict(steps, seed):
    generator = torch.manual_seed(seed)
    for i in range(1,steps):
        yield pipeline(generator=generator, num_inference_steps=i)["sample"][0]

Version 3.2

New Features:

1. Improvements to Queuing 🥇

We've implemented a brand new queuing system based on web sockets instead of HTTP long polling. Among other things, this allows us to manage queue sizes better on Hugging Face Spaces. There are also additional queue-related parameters you can add:

  • Now supports concurrent workers (parallelization)
demo = gr.Interface(...)
demo.queue(concurrency_count=3)
demo.launch()
  • Configure a maximum queue size
demo = gr.Interface(...)
demo.queue(max_size=100)
demo.launch()
  • If a user closes their tab / browser, they leave the queue, which means the demo will run faster for everyone else

2. Fixes to Examples

  • Dataframe examples will render properly, and look much clearer in the UI: (thanks to PR #2125)

Screen Shot 2022-08-30 at 8 29 58 PM

  • Image and Video thumbnails are cropped to look neater and more uniform: (thanks to PR #2109)

Screen Shot 2022-08-30 at 8 32 15 PM

  • Other fixes in PR #2131 and #2064 make it easier to design and use Examples

3. Component Fixes 🧱

  • Specify the width and height of an image in its style tag (thanks to PR #2133)
components.Image().style(height=260, width=300)
  • Automatic conversion of videos so they are playable in the browser (thanks to PR #2003). Gradio will check if a video's format is playable in the browser and, if it isn't, will automatically convert it to a format that is (mp4).
  • Pass in a json filepath to the Label component (thanks to PR #2083)
  • Randomize the default value of a Slider (thanks to PR #1935)

slider-random

  • Improvements to State in PR #2100

4. Ability to Randomize Input Sliders and Reload Data whenever the Page Loads

  • In some cases, you want to be able to show a different set of input data to every user as they load the page app. For example, you might want to randomize the value of a "seed" Slider input. Or you might want to show a Textbox with the current date. We now supporting passing functions as the default value in input components. When you pass in a function, it gets re-evaluated every time someone loads the demo, allowing you to reload / change data for different users.

Here's an example loading the current date time into an input Textbox:

import gradio as gr
import datetime

with gr.Blocks() as demo:
    gr.Textbox(datetime.datetime.now)

demo.launch()

Note that we don't evaluate the function -- datetime.datetime.now() -- we pass in the function itself to get this behavior -- datetime.datetime.now

Because randomizing the initial value of Slider is a common use case, we've added a randomize keyword argument you can use to randomize its initial value:

import gradio as gr
demo = gr.Interface(lambda x:x, gr.Slider(0, 10, randomize=True), "number")
demo.launch()

5. New Guide 🖊️

Full Changelog:

Contributors Shoutout:

Version 3.1

New Features:

1. Embedding Demos on Any Website 💻

With PR #1444, Gradio is now distributed as a web component. This means demos can be natively embedded on websites. You'll just need to add two lines: one to load the gradio javascript, and one to link to the demos backend.

Here's a simple example that embeds the demo from a Hugging Face space:

<script
	type="module"
	src="https://gradio.s3-us-west-2.amazonaws.com/3.0.18/gradio.js"
></script>
<gradio-app space="abidlabs/pytorch-image-classifier"></gradio-app>

But you can also embed demos that are running anywhere, you just need to link the demo to src instead of space. In fact, all the demos on the gradio website are embedded this way:

Screen Shot 2022-07-14 at 2 41 44 PM

Read more in the Embedding Gradio Demos guide.

2. Reload Mode 👨‍💻

Reload mode helps developers create gradio demos faster by automatically reloading the demo whenever the code changes. It can support development on Python IDEs (VS Code, PyCharm, etc), the terminal, as well as Jupyter notebooks.

If your demo code is in a script named app.py, instead of running python app.py you can now run gradio app.py and that will launch the demo in reload mode:

Launching in reload mode on: http://127.0.0.1:7860 (Press CTRL+C to quit)
Watching...
WARNING: The --reload flag should not be used in production on Windows.

If you're working from a Jupyter or Colab Notebook, use these magic commands instead: %load_ext gradio when you import gradio, and %%blocks in the top of the cell with the demo code. Here's an example that shows how much faster the development becomes:

Blocks

3. Inpainting Support on gr.Image() 🎨

We updated the Image component to add support for inpainting demos. It works by adding tool="sketch" as a parameter, that passes both an image and a sketchable mask to your prediction function.

Here's an example from the LAMA space:

FXApVlFVsAALSD-

4. Markdown and HTML support in Dataframes 🔢

We upgraded the Dataframe component in PR #1684 to support rendering Markdown and HTML inside the cells.

This means you can build Dataframes that look like the following:

image (8)

5. gr.Examples() for Blocks 🧱

We've added the gr.Examples component helper to allow you to add examples to any Blocks demo. This class is a wrapper over the gr.Dataset component.

Screen Shot 2022-07-14 at 2 23 50 PM

gr.Examples takes two required parameters:

  • examples which takes in a nested list
  • inputs which takes in a component or list of components

You can read more in the Examples docs or the Adding Examples to your Demos guide.

6. Fixes to Audio Streaming

With PR 1828 we now hide the status loading animation, as well as remove the echo in streaming. Check out the stream_audio demo for more or read through our Real Time Speech Recognition guide.

Version 3.0

🔥 Gradio 3.0 is the biggest update to the library, ever.

New Features:

1. Blocks 🧱

Blocks is a new, low-level API that allows you to have full control over the data flows and layout of your application. It allows you to build very complex, multi-step applications. For example, you might want to:

  • Group together related demos as multiple tabs in one web app
  • Change the layout of your demo instead of just having all of the inputs on the left and outputs on the right
  • Have multi-step interfaces, in which the output of one model becomes the input to the next model, or have more flexible data flows in general
  • Change a component's properties (for example, the choices in a Dropdown) or its visibility based on user input

Here's a simple example that creates the demo below it:

import gradio as gr

def update(name):
    return f"Welcome to Gradio, {name}!"

demo = gr.Blocks()

with demo:
    gr.Markdown(
    """
    # Hello World!
    Start typing below to see the output.
    """)
    inp = gr.Textbox(placeholder="What is your name?")
    out = gr.Textbox()

    inp.change(fn=update,
               inputs=inp,
               outputs=out)

demo.launch()
