自己训练的图片分类model pyinstaller 打包程序后偶尔出现该问题

出现原因

使用 @loguru.logger.catch捕捉以下异常

File "C:\Python\3.7.9\lib\site-packages\paddlex\cv\models\load_model.py", line 146, in load_model logging.info("Model[{}] loaded.".format(model_info['Model'])) │ │ └ {'Model': 'PPLCNet', 'Transforms': [{'ResizeByShort': {'interp': 'LINEAR', 'max_size': -1, 'short_size': 256}}, {'CenterCrop'... │ └ <function info at 0x000001821FA1E048> └ <module 'paddlex.utils.logging' from 'C:\Python\3.7.9\lib\site-packages\paddlex\utils\logging.py'>

对sys.stdout 没有做 None 判断导致
