Gradio is a python library that allows you to easily create input and output interfaces over trained models to make it easy for you to "play around" with your model in your browser by dragging-and-dropping in your own images (or pasting your own text, recording your own voice, etc.) and seeing what the model outputs. Gradio also creates a shareable, public link to your model so you can share the interface with others (e.g. your client, your advisor, or your dad), who can use the model without writing any code.

Gradio is useful for:

  • Creating demos for clients
  • Getting feedback from collaborators
  • Debugging your model during development

To get a sense of gradio, take a look at the python notebooks in the examples folder, or read on below! And be sure to visit the gradio website:


pip install gradio

(you may need to replace pip with pip3 if you're running python3).


Gradio is very easy to use with your existing code. Here is a minimum working example:

import gradio
import tensorflow as tf
image_mdl = tf.keras.applications.inception_v3.InceptionV3()

io = gradio.Interface(inputs="imageupload", outputs="label", model_type="keras", model=image_mdl)

You can supply your own model instead of the pretrained model above, as well as use different kinds of models, not just keras models. Changing the input and output parameters in the Interface face object allow you to create different interfaces, depending on the needs of your model. Take a look at the python notebooks for more examples. The currently supported interfaces are as follows:

Input interfaces:

  • Sketchpad
  • ImageUplaod
  • Webcam
  • Textbox

Output interfaces:

  • Label
  • Textbox


Here are a few screenshots that show examples of gradio interfaces
