> Can you explain what this is issue that you are having with the metrics ? LGTM otherwise

The issue occurs when I use **ms-swift** to SFT a model with the `report_to=mlflow` setting. During training, the `MLflowCallback` from transformers is triggered, but some metric names (like `"train_speed(iter/s)"`) contain invalid characters such as parentheses, which MLflow does not accept. This causes errors like:
> 20:37:08 ERROR mlflow.utils.async_logging.async_logging_queue: Run Id 1f4f463a9ddc4e01a61f258d321f01f6: Failed to log run data: Exception: INVALID_PARAMETER_VALUE: Invalid value "train_speed(iter/s)" for parameter 'metrics[4].name' supplied: Names may only contain alphanumerics, underscores (_), dashes (-), periods (.), spaces ( ), colon(:) and slashes (/).

Sounds good, if you can just add a comment in the code to specify that, it will be better 

please also fix the style with `make style `
