#error C++17 or later compatible compiler is required to ~~~~

When I run that code
cmake --build build --target main --config RelWithDebInfo -j

The following error occurs:
#error C++17 or later compatible compiler is required to ~~~~

My g++ version looks like this:

g++ (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0

How can I solve this??

One thing I didn't mention is that since I use cuda version 11.8, I installed a different version of libtorch than the one suggested on git hub.

I also have this issue before. I solved it by installing cuda 11.7 and followed the same version as auther suggestion.
