Error when create training data sets

Hi, really thanks for the excellent tool.

I faced an error when creating training datasets by GUI.
I am not sure if the error was caused by the Chinese characters in the pathway.
If that is the case, is there any suggestion to resolve it?
Thanks a lot.

Here is the error message.

python 3.6.9
DLC 2.1.4
Tensorflow 1.8.0
Windows 10 Professional (Tranditional Chinese version)
