你好，segment fault通常是内存相关问题。可否贴一下您的代码，并告知运行方法，方便我们复现找到问题所在？

我也遇到了，运行就会报错，但是是偶发的，有时候会报错有时候不会

运行paddle.utils.run_check()就是这个错误了 wsl2+cuda11.7

[Giszy]

@fmscole 问题分析： paddle.utils.run_check()运行的时候会搜索libcuda.so，但在WSL2下，该文件是Windows的路径"C:\Windows\System32\lxss\lib\libcuda.so"。所以，出现FatalError: Segmentation fault is detected by the operating system，就是因为在WSL2的Ubuntu系统中缺少libcuda.so所致。

解决方案：将libcuda.so拷贝到/usr/local/cuda/lib64/下即可。测试通过。
