Bug描述 Describe the Bug

在执行https://github.com/PaddlePaddle/PaddleSeg/blob/release/2.6/docs/quick_start_cn.md demo时，python train.py及python val.py均能正常运行，但是在执行python predict.py时报错：

C++ Traceback (most recent call last):

0 ImagingZipEncode 1 deflateReset

---

Error Message Summary:

FatalError: Segmentation fault is detected by the operating system. [TimeInfo: Aborted at 1707286977 (unix time) try "date -d @1707286977" if you are using GNU date ] [SignalInfo: SIGSEGV (@0x0) received by PID 4193083 (TID 0x7f6cb3650480) from PID 0 ]

Segmentation fault (core dumped)

经过Debug，确认是在脚本的最后执行 pred_mask.save(pred_saved_path) 语句时报错的，进一步调试发现，是在执行ImageFile.py中的errcode, data = encoder.encode(bufsize)[1:]语句时返回的。

你好，根据你提供的信息，这个错误出现在文件保存中，请进一步查看pred_mask中是否有非法值。

I also faced similar issue as you when I was training my own model which is HrSegNet. I could train my own model in Windows OS but not Linux, my Linux environment is the same as yours. Not sure where cause the issues.
