Is the cats x dogs site still working

I am trying to use Home | Jeremy Howard but after choosing the file to upload the name of the file is just rendered on the screen but that’s it. I don’t have the same result Jeremy does it in the video.
On using Gradio Predict API Docs ( live demo I get response: { detail: 'Not Found' } . Is it still worth to try and make a gradio/github pages out of this pickle or should I just skip to training my own model?
