该错误是由于在设置日志时，代码在检查当前系统是否为Windows，以及系统的标准输出编码是否为utf-8之前，尝试访问sys.stdout.encoding，但因为sys.stdout可能为None，因此引发了AttributeError。修复此错误的方法是在代码之前添加sys.stdout是否为None的检查。 代码示例： import sys from ultralytics.utils.logger import set_logging LOGGER_NAME = 'my_logger' VERBOSE = True if sys.stdout is not None:

if sys.platform == 'win32' and sys.stdout.encoding != 'utf-8':
    sys.stdout = open(sys.stdout.fileno(), mode='w', encoding='utf-8', buffering=1)

LOGGER = set_logging(LOGGER_NAME, verbose=VERBOSE)
