I'm using the gradio library with one of the basic examples, but am getting this error. I am running this in a Google Colab Notebook. Here is the relevant lines of code:

fare = gr.inputs.Slider(minimum=0, maximum=1000, default=100, label="Fare (british pounds)")
gr.Interface(predict_survival, [sex, age, fare], "label", live=True).launch();

The error is:

MissingSchema: Invalid URL 'None': No schema supplied. Perhaps you meant http://None?

This error happens with older versions of Gradio. Please force upgrade to the latest version of Gradio (sometimes colab doesn't do this automatically):

pip install gradio --upgrade
