torch_utils.float64 return torch.float64 or torch.float32 base on torch.Tensor.device.type

not sure if this is the best solution to solve this ideally there should be a way to solve this globally

note: logically this should workrl but as I don't have mps or xpu device so this is technically not fully tested
