问题
在rk3588上，python程序运行过程中报错 Segmentation fault (core dumped)
分析
利用gdb，操作方式如下：
gdb python
(gdb) run main.py
## wait for segfault ##
(gdb) backtrace #（或者bt）
## stack trace of the py code
run main.py 执行后，报错情况取下：
Thread 40 "python" received signal SIGSEGV, Segmentation fault.

解决思路：
该程序在rk3588+Ubuntu上运行正常，所有优先考虑迁移到rk3588+openEuler后环境的问题，通过排查，最终定位代码问题，通过修改代码进行适配。
