问题：运行python程序出现Segmentation fault (core dumped)问题。

bdlf@bdlf-desktop:~/2、car_detect$ python3 test_zxh.py 
Segmentation fault (core dumped)

解决思路：

在主程序最开始加入两行代码：

import faulthandler
faulthandler.enable()
# 下面是原代码

运行程序，出现以下问题： 

OSError: libcublasLt.so.10: cannot open shared object file: No such file or directory

查看CUDA Toolkit是否已经安装在系统上，若已安装，确保libcublasLt.so.10文件存在于系统上，可以使用如下命令查找该文件：

bdlf@bdlf-desktop:~/1、logistics_service$ find /usr/local -name libcublasLt.so.10
/usr/local/cuda-10.2/targets/aarch64-linux/lib/libcublasLt.so.10

重新安装nvidia-jetpack后，再次尝试运行程序，又出现新的问题，可能与torch有关。

import torch后问题复现，接下来就是重新安装torch，到此问题完美解决啦~~
