When i try to run this command I get an Error like this

`` -- Configuring bitsandbytes (Backend: hip) -- NO_CUBLASLT := OFF -- The HIP compiler identification is unknown -- Detecting HIP compiler ABI info -- Detecting HIP compiler ABI info - failed -- Check for working HIP compiler: /opt/rocm-6.1.1/llvm/bin/clang++ -- Check for working HIP compiler: /opt/rocm-6.1.1/llvm/bin/clang++ - broken CMake Error at /usr/share/cmake-3.29/Modules/CMakeTestHIPCompiler.cmake:73 (message): The HIP compiler

is not able to compile a simple test program.

It fails with the following output:

Hi @shriharshan , the 'cmath' file not found has a troubleshooting page: https://rocm.docs.amd.com/projects/install-on-linux/en/develop/how-to/native-install/install-faq.html#issue-4-c-libraries

Please try this suggestion and let me know if it helps.
