关于YOLOv8的GUI打包出现的问题

Question

为什么我使用pyinstaller打包我的pyqt6项目，之后生成了exe文件，点击exe文件之后报错如下

我发现都是跟编码问题有关encoding="utf-8"，但是试了很多方法都没有效果

本答案参考ChatGPT-3.5

根据错误信息，问题似乎出在ultralytics库中的日志设置部分。具体地，出错的地方是在ultralytics.utils模块的set_logging函数的line 238处。

错误信息中提到了一个'NoneType' object has no attribute 'encoding'的错误，这意味着sys.stdout对象为空，没有encoding属性。这通常是由于在GUI应用程序中使用pyinstaller打包时引起的。

解决这个问题的一种方法是修改ultralytics.utils模块的set_logging函数，以确保在sys.stdout为空时不进行编码配置。

解决方案：

1. 打开ultralytics/utils/init.py文件。
2. 找到set_logging函数，即第238行，将以下代码修改为：

if WINDOWS and sys.stdout and sys.stdout.encoding and sys.stdout.encoding != "utf-8":

1. 保存文件，并重新运行pyinstaller来生成exe文件。

这样修改后，set_logging函数将首先检查sys.stdout是否存在，然后再检查其是否具有encoding属性。这样可以避免'NoneType' object has no attribute 'encoding'错误的出现。

希望这个解决方案能够帮助你解决问题！如果仍然有其他问题，请随时提问。
