Interface

+ + + + + +
+ +
gradio.Interface(fn, inputs, outputs, ···)
+ + +

Interface is Gradio's main high-level class, and allows you to create a web-based GUI / demo around a machine learning model (or any Python function) in a few lines of code. You must specify three parameters: (1) the function to create a GUI for (2) the desired input components and (3) the desired output components. Additional parameters can be used to control the appearance and behavior of the demo.

+
+ + + +

Example Usage

+
+
import gradio as gr
+
+def image_classifier(inp):
+    return {'cat': 0.3, 'dog': 0.7}
+
+demo = gr.Interface(fn=image_classifier, inputs="image", outputs="label")
+demo.launch()
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterDescription
+ + fn + +

Callable

+ +

required

+ +
+

the function to wrap an interface around. Often a machine learning model's prediction function. Each parameter of the function corresponds to one input component, and the function should return a single value or a tuple of values, with each element in the tuple corresponding to one output component.

+
+ + inputs + +

str | IOComponent | List[str | IOComponent] | None

+ +

required

+ +
+

a single Gradio component, or list of Gradio components. Components can either be passed as instantiated objects, or referred to by their string shortcuts. The number of input components should match the number of parameters in fn. If set to None, then only the output components will be displayed.

+
+ + outputs + +

str | IOComponent | List[str | IOComponent] | None

+ +

required

+ +
+

a single Gradio component, or list of Gradio components. Components can either be passed as instantiated objects, or referred to by their string shortcuts. The number of output components should match the number of values returned by fn. If set to None, then only the input components will be displayed.

+
+ + examples + +

List[Any] | List[List[Any]] | str | None

+ +

default: None

+ +
+

sample inputs for the function; if provided, appear below the UI components and can be clicked to populate the interface. Should be nested list, in which the outer list consists of samples and each inner list consists of an input corresponding to each input component. A string path to a directory of examples can also be provided, but it should be within the directory with the python file running the gradio app. If there are multiple input components and a directory is provided, a log.csv file must be present in the directory to link corresponding inputs.

+
+ + cache_examples + +

bool | None

+ +

default: None

+ +
+

If True, caches examples in the server for fast runtime in examples. The default option in HuggingFace Spaces is True. The default option elsewhere is False.

+
+ + examples_per_page + +

int

+ +

default: 10

+ +
+

If examples are provided, how many to display per page.

+
+ + live + +

bool

+ +

default: False

+ +
+

whether the interface should automatically rerun if any of the inputs change.

+
+ + interpretation + +

Callable | str | None

+ +

default: None

+ +
+

function that provides interpretation explaining prediction output. Pass "default" to use simple built-in interpreter, "shap" to use a built-in shapley-based interpreter, or your own custom interpretation function. For more information on the different interpretation methods, see the Advanced Interface Features guide.

+
+ + num_shap + +

float

+ +

default: 2.0

+ +
+

a multiplier that determines how many examples are computed for shap-based interpretation. Increasing this value will increase shap runtime, but improve results. Only applies if interpretation is "shap".

+
+ + title + +

str | None

+ +

default: None

+ +
+

a title for the interface; if provided, appears above the input and output components in large font. Also used as the tab title when opened in a browser window.

+
+ + description + +

str | None

+ +

default: None

+ +
+

a description for the interface; if provided, appears above the input and output components and beneath the title in regular font. Accepts Markdown and HTML content.

+
+ + article + +

str | None

+ +

default: None

+ +
+

an expanded article explaining the interface; if provided, appears below the input and output components in regular font. Accepts Markdown and HTML content.

+
+ + thumbnail + +

str | None

+ +

default: None

+ +
+

path or url to image to use as display image when the web demo is shared on social media.

+
+ + theme + +

str | None

+ +

default: None

+ +
+

one of "never", "auto", or "manual". If "never" or "auto", users will not see a button to flag an input and output. If "manual", users will see a button to flag. If "auto", every input the user submits will be automatically flagged (outputs are not flagged). If "manual", both the input and outputs are flagged when the user clicks flag button. This parameter can be set with environmental variable GRADIO_ALLOW_FLAGGING; otherwise defaults to "manual".

+
+ + flagging_options + +

List[str] | None

+ +

default: None

+ +
+

if provided, allows user to select from the list of options when flagging. Only applies if allow_flagging is "manual".

default: False

+ +
+

If True, then the function should process a batch of inputs, meaning that it should accept a list of input values for each parameter. The lists should be of equal length (and be up to length `max_batch_size`). The function is then *required* to return a tuple of lists (even if there is only 1 output component), with each list in the tuple corresponding to one output component.

+
+ + max_batch_size + +

int

+ +

default: 4

+ +
+

Maximum number of inputs to batch together if this is called from the queue (only relevant if batch=True)

+
+ + + + +

+

+ Flagging +

+

+ A Gradio Interface includes a "Flag" button that appears + underneath the output. By default, clicking on the Flag button sends the input and output + data back to the machine where the gradio demo is running, and saves it to a CSV log file. + But this default behavior can be changed. To set what happens when the Flag button is clicked, + you pass an instance of a subclass of FlaggingCallback to the flagging_callback parameter + in the Interface constructor. You can use one of the FlaggingCallback subclasses + that are listed below, or you can create your own, which lets you do whatever + you want with the data that is being flagged. +

+
+ + + +
+ + + + + + + + +
+ +

SimpleCSVLogger

+ + + +
+ +
gradio.SimpleCSVLogger(···)
+ + +

A simplified implementation of the FlaggingCallback abstract class provided for illustrative purposes. Each flagged sample (both the input and output data) is logged to a CSV file on the machine running the gradio app.

+
+ + + +

Example Usage

+
+
import gradio as gr
+def image_classifier(inp):
+    return {'cat': 0.3, 'dog': 0.7}
+demo = gr.Interface(fn=image_classifier, inputs="image", outputs="label",
+                    flagging_callback=SimpleCSVLogger())

CSVLogger

+ + + +
+ +
gradio.CSVLogger(···)
+ + +

The default implementation of the FlaggingCallback abstract class. Each flagged sample (both the input and output data) is logged to a CSV file with headers on the machine running the gradio app.

+
+ + + +

Example Usage

+
+
import gradio as gr
+def image_classifier(inp):
+    return {'cat': 0.3, 'dog': 0.7}

Series

+ + + + + +
+ +
gradio.Series(interfaces, ···)
+ + +

Creates a new Interface from multiple Interfaces in series (the output of one is fed as the input to the next, and so the input and output components must agree between the interfaces).

+
+ + + + +
+
import gradio as gr
+
+get_name = gr.Interface(lambda name: name, inputs="textbox", outputs="textbox")
+prepend_hello = gr.Interface(lambda name: f"Hello {name}!", inputs="textbox", outputs="textbox")
+append_nice = gr.Interface(lambda greeting: f"{greeting} Nice to meet you!",
+                           inputs="textbox", outputs=gr.Textbox(label="Greeting"))
+demo = gr.Series(get_name, prepend_hello, append_nice)

Blocks

+ + + + + +
+ +
with gradio.Blocks():
+ + +

Blocks is Gradio's low-level API that allows you to create more custom web applications and demos than Interfaces (yet still entirely in Python).

Compared to the Interface class, Blocks offers more flexibility and control over: (1) the layout of components (2) the events that trigger the execution of functions (3) data flows (e.g. inputs can trigger outputs, which can trigger the next level of outputs). Blocks also offers ways to group together related demos such as with tabs.

The basic usage of Blocks is as follows: create a Blocks object, then use it as a context (with the "with" statement), and then define layouts, components, or events within the Blocks context. Finally, call the launch() method to launch the demo.

+
+ + + +

Example Usage

+
+
import gradio as gr
+def update(name):
+    return f"Welcome to Gradio, {name}!"
+
+with gr.Blocks() as demo:
+    gr.Markdown("Start typing below and then click **Run** to see the output.")
+    with gr.Row():
+        inp = gr.Textbox(placeholder="What is your name?")
+        out = gr.Textbox()
+    btn = gr.Button("Run")
+    btn.click(fn=update, inputs=inp, outputs=out)
+
+demo.launch()
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterDescription
+ + theme + +

str

+ +

default: "default"

+ +
+

which theme to use - right now, only "default" is supported.

+
+ + analytics_enabled + +

bool | None

+ +

default: None

+ +
+

whether to allow basic telemetry. If None, will use GRADIO_ANALYTICS_ENABLED environment variable or default to True.

+
+ + mode + +

str

+ +

default: "blocks"

+ +
+

a human-friendly name for the kind of Blocks or Interface being created.

+
+ + title + +

str

+ +

default: "Gradio"

+ +
+

The tab title to display when this is opened in a browser window.

+
+ + css + +

str | None

+ +

default: None

+ +
+

custom css or path to custom css file to apply to entire Blocks

+
+ + + + +

Methods

+
+ + + +
+ + + + + + + + +
+ +

load

+ + + +
+ +
gradio.Blocks.load(···)
+ + +

For reverse compatibility reasons, this is both a class method and an instance method, the two of which, confusingly, do two completely different things.

Class method: loads a demo from a Hugging Face Spaces repo and creates it locally and returns a block instance. Equivalent to gradio.Interface.load()

Instance method: adds event that runs as soon as the demo loads in the browser. Example usage below.

+
+ + + +

Example Usage

+
+
import gradio as gr
+import datetime
+with gr.Blocks() as demo:
+    def get_time():
+        return datetime.datetime.now().time()
+    dt = gr.Textbox(label="Current time")
+    demo.load(get_time, inputs=None, outputs=dt)
+demo.launch()
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterDescription
+ + fn + +

Callable | None

+ +

default: None

+ +
+

Instance Method - the function to wrap an interface around. Often a machine learning model's prediction function. Each parameter of the function corresponds to one input component, and the function should return a single value or a tuple of values, with each element in the tuple corresponding to one output component.

+
+ + inputs + +

List[Component] | None

+ +

default: None

+ +
+

Instance Method - List of gradio.components to use as inputs. If the function takes no inputs, this should be an empty list.

+
+ + outputs + +

List[Component] | None

+ +

default: None

+ +
+

Instance Method - List of gradio.components to use as inputs. If the function returns no outputs, this should be an empty list.

+
+ + api_name + +

str | None

+ +

default: None

+ +
+

Instance Method - Defining this parameter exposes the endpoint in the api docs

+
+ + scroll_to_output + +

bool

+ +

default: False

+ +
+

Instance Method - If True, will scroll to output component on completion

+
+ + show_progress + +

bool

+ +

default: True

+ +
+

Instance Method - If True, will show progress animation while pending

+
+ + queue + +

+ +

default: None

+ +
+

Instance Method - If True, will place the request on the queue, if the queue exists

+
+ + batch + +

bool

+ +

default: False

+ +
+

Instance Method - If True, then the function should process a batch of inputs, meaning that it should accept a list of input values for each parameter. The lists should be of equal length (and be up to length `max_batch_size`). The function is then *required* to return a tuple of lists (even if there is only 1 output component), with each list in the tuple corresponding to one output component.

+
+ + max_batch_size + +

int

+ +

default: 4

+ +
+

Instance Method - Maximum number of inputs to batch together if this is called from the queue (only relevant if batch=True)

+
+ + preprocess + +

bool

+ +

default: True

+ +
+

Instance Method - If False, will not run preprocessing of component data before running 'fn' (e.g. leaving it as a base64 string if this method is called with the `Image` component).

+
+ + postprocess + +

bool

+ +

default: True

+ +
+

Instance Method - If False, will not run postprocessing of component data before returning 'fn' output to the browser.

+
+ + every + +

float | None

+ +

default: None

+ +
+

Instance Method - Run this event 'every' number of seconds. Interpreted in seconds. Queue must be enabled.

+
+ + name + +

str | None

+ +

default: None

+ +
+

Class Method - the name of the model (e.g. "gpt2" or "facebook/bart-base") or space (e.g. "flax-community/spanish-gpt2"), can include the `src` as prefix (e.g. "models/facebook/bart-base")

+
+ + src + +

str | None

+ +

default: None

+ +
+

Class Method - the source of the model: `models` or `spaces` (or leave empty if source is provided as a prefix in `name`)

+
+ + api_key + +

str | None

+ +

default: None

+ +
+

Class Method - optional access token for loading private Hugging Face Hub models or spaces. Find your token here: https://huggingface.co/settings/tokens

+
+ + alias + +

str | None

+ +

default: None

+ +
+

Class Method - optional string used as the name of the loaded model instead of the default name (only applies if loading a Space running Gradio 2.x)

+
+ + + + + +

+ Components +

+

+ Gradio includes pre-built components that can be used as + inputs or outputs in your Interface or Blocks with a single line of code. Components + include preprocessing steps that convert user data submitted through browser + to something that be can used by a Python function, and postprocessing + steps to convert values returned by a Python function into something that can be displayed in a browser. +

+

+ Consider an example with three inputs (Textbox, Number, and Image) and two outputs + (Number and Gallery), below is a diagram of what our preprocessing will send to the function and what + our postprocessing will require from it. +

+ +

+ Components also come with certain events that they support. These are methods that are triggered with user actions. + Below is a table showing which events are supported for each component. All events are also listed (with parameters) in the component's docs. +

+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Methods

+
+ + + +
+ + + + + + + + +
+ +

change

+ + + +
+ +
gradio.Textbox.change(fn, ···)
+ + +

This event is triggered when the component's input value changes (e.g. when the user types in a textbox or uploads an image). This method can be used when this component is in a Gradio Blocks.

+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterDescription

Image

+ + + + + +
+ +
gradio.Image(···)
+ + + +
+ + + +

Creates an image component that can be used to upload/draw images (as an input) or display images (as an output).

+
+ +

As input: passes the uploaded image as a numpy.array, PIL.Image or str filepath depending on `type` -- unless `tool` is `sketch` AND source is one of `upload` or `webcam`. In these cases, a dict with keys `image` and `mask` is passed, and the format of the corresponding values depends on `type`.

+

As output: expects a numpy.array, PIL.Image or str or pathlib.Path filepath to an image and displays the image.

+ +

Format expected for examples: a str filepath to a local file that contains the image.

Video

+ + + + + +
+ +
gradio.Video(···)
+ + + +
+ + + +
+ + +

Creates a video component that can be used to upload/record videos (as an input) or display videos (as an output). For the video to be playable in the browser it must have a compatible container and codec combination. Allowed combinations are .mp4 with h264 codec, .ogg with theora codec, and .webm with vp9 codec. If the component detects that the output video would not be playable in the browser it will attempt to convert it to a playable mp4 video. If the conversion fails, the original video is returned.

+
+ +

As input: passes the uploaded video as a str filepath or URL whose extension can be modified by `format`.

+

As output: expects a str filepath to a video which is displayed.

+ +

Format expected for examples: a str filepath to a local file that contains the video.

+ + +

Supported events: change(), clear(), pause(), play(), stop(), upload()

As input: passes the uploaded audio as a Tuple(int, numpy.array) corresponding to (sample rate, data) or as a str filepath, depending on `type`

+

As output: expects a Tuple(int, numpy.array) corresponding to (sample rate, data) or as a str filepath or URL to an audio file, which gets displayed

+ +

Format expected for examples: a str filepath to a local file that contains audio.

+ + +

Supported events: change(), clear(), pause(), play(), stop(), stream(), upload()

change

+ + + +
+ +
gradio.Model3D.change(fn, ···)
+ + +

This event is triggered when the component's input value changes (e.g. when the user types in a textbox or uploads an image). This method can be used when this component is in a Gradio Blocks.

+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterDescription
+ + fn + +

Callable | None

+ +

Progress

+ + + + + +
+ +
gradio.Progress(···)
+ + + +
+ + + +
+ + +

The Progress class provides a custom progress tracker that is used in a function signature. To attach a Progress tracker to a function, simply add a parameter right after the input parameters that has a default value set to a `gradio.Progress()` instance. The Progress tracker can then be updated in the function by calling the Progress object or using the `tqdm` method on an Iterable. The Progress tracker is currently only available with `queue()`.

+
+ + + +

Example Usage

+
+
import gradio as gr
+import time
+def my_function(x, progress=gr.Progress()):
+    progress(0, desc="Starting...")
+    time.sleep(1)
+    for i in progress.tqdm(range(100)):
+        time.sleep(0.1)
+    return x
+gr.Interface(my_function, gr.Textbox(), gr.Textbox()).queue().launch()
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterDescription
+ + track_tqdm + +

bool

+ +

default: False

+ +
+

If True, the Progress object will track any tqdm.tqdm iterations with the tqdm library in the function.

+
+ + + + +

update

+ + + + + +
+ +
gradio.update(kwargs, ···)
+ + +

Updates component properties. When a function passed into a Gradio Interface or a Blocks events returns a typical value, it updates the value of the output component. But it is also possible to update the properties of an output component (such as the number of lines of a `Textbox` or the visibility of an `Image`) by returning the component's `update()` function, which takes as parameters any of the constructor parameters for that component. This is a shorthand for using the update method on a component. For example, rather than using gr.Number.update(...) you can just use gr.update(...). Note that your editor's autocompletion will suggest proper parameters if you use the update method on the component.

+
+ + + +

Example Usage

+
+
# Blocks Example
+import gradio as gr
+with gr.Blocks() as demo:
+    radio = gr.Radio([1, 2, 4], label="Set the value of the number")
+    number = gr.Number(value=2, interactive=True)
+    radio.change(fn=lambda value: gr.update(value=value), inputs=radio, outputs=number)
+demo.launch()
+
+# Interface example
+import gradio as gr
+def change_textbox(choice):
+  if choice == "short":
+      return gr.Textbox.update(lines=2, visible=True)
+  elif choice == "long":
+      return gr.Textbox.update(lines=8, visible=True)
+  else:
+      return gr.Textbox.update(visible=False)
+gr.Interface(
+  change_textbox,
+  gr.Radio(
+      ["short", "long", "none"], label="What kind of essay would you like to write?"
+  ),
+  gr.Textbox(lines=2),
+  live=True,
+).launch()
+
+ + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterDescription
+ + kwargs + +

+ +
