Puppeteer Runtime Error

[DearVa]

This happened when I try to run "puppeteer.py", my camera worked perfectly and I could see my face was highlighted. However, when I import a image, it stopped working and showed this:
Exception in Tkinter callback

I can run "manual_poser.py" perfectly and no exception was thrown.
