Hi qingchunlizhi
This source code is a bit old, so it is possibly caused by some python packages.
Which version of python are you using? 2.x or 3.x?

python 2.x

I am getting the same error. Was the issue resolved?

This code is a bit old so I'm thinking of updating it.

[purplepeach29]

If you could update it sooner, that would be of great help. Thank you.
