It gives an error: "AttributeError: module 'message' has no attribute '__all__'", what should I do?

Question

Python

When I try to run the script, I get an error that there is no message module, I find it through the project interpreter and try to install it, but it says that there is no observable module, I install it. Again I try to set message , I get an error: "AttributeError: module 'message' has no attribute '__all__'".

Tell me how to solve the problem?
PS via "cmd" is the same.
