Description

When I was training Vicuna-7b on the A100 (40g) graphics card, this error occurred. Has anyone resolved this error and successfully trained? RuntimeError: Expected q_dtype == torch::kFloat16 || (is_sm8x && q_dtype ==
torch::kBFloat16) to be true, but got false. (Could this error message be
improved? If so, please report an enhancement request to PyTorch.)
