Thanks for great code!
I encountered this problem every time I finished running code. Although my code had completed but it's pretty weird, nothing bad happened while running but a bug just show up at the end.

And also, when i done running a .py file using NLPClient, my folder appears one more this

Thanks in advance! Have a great day!
