阳神能不能帮我看看为什么编译失败报错RuntimeError: Error building extension 'add2'，后面这句不理解fatal error: add2.h: No such file or directory

[Henry-Avery]

我在Jupiter notebook里运行下面jit命令的编译报错如下
python3 time.py --compiler jit

我把#nclude路径改完#include "../include/add2.h"之后就找到文件了，但是又有新的报错error: expected constructor, destructor, or type conversion before ‘(’ token TORCH_LIBRARY(add2, m)

请问报错解决了吗？同样的报错。
