I have found the cause of the problem. The reason is: the versions of ultralytics and yolov8 do not match. My yolov8 is version 8.1 and ultralytics is version 8.2. I downgraded ultralytics to 8.1. After training again, I got best.pt and no error was reported after running the test case.

@807xuan great job pinpointing the version mismatch issue! Matching the versions of YOLOv8 and the Ultralytics library often resolves such errors. If you have any more questions or face further issues, feel free to reach out. Happy coding! 😊
