@zkjqw139 Firstly, I want to thank you for your reply, so you are right I figured this issue by the same your suggestion, but I still stuck in the other errors.
I'm not sure if this error belongs to running the code in windows system or other reasons, because I'm a beginner. Let me show the errors:

So I hope to find any suggestions, thanks advance.
