Quick-draw in tutorial doesn't work in space

As a beginner, I was trying to deploy the quick-draw in my space following the tutorial. However, it didn’t work even after I fully duplicated the one from the other’s space.

My space: frank1206 (guan)
The one I copied from: Quickdraw - a Hugging Face Space by mmsamuel

One interesting finding is the sketchpad looks different between us, but not sure why. Is it because of gradio versions are different? I tried to use old ones but still didn’t help.
