 ## Error handling
 Call CUDA APIs via the provided helper macros `RAFT_CUDA_TRY`, `RAFT_CUBLAS_TRY` and `RAFT_CUSOLVER_TRY`. These macros take care of checking the return values of the used API calls and generate an exception when the command is not successful. If you need to avoid an exception, e.g. inside a destructor, use `RAFT_CUDA_TRY_NO_THROW`, `RAFT_CUBLAS_TRY_NO_THROW ` and `RAFT_CUSOLVER_TRY_NO_THROW ` (currently not available, see https://github.com/rapidsai/cuml/issues/229). These macros log the error but do not throw an exception.
