Hello, it's an honor to watch the work. It's very helpful and has benefited me a lot. But I found a problem. The file you uploaded is missing a Py file named classBarra. Please share it or send it to my email lrBkDV@outlook.com. Thank you very much. In addition, I hope you can tell me the name of your paper. I want to study it. Similarly, you can send it to my email. Thank you again.
