not compatible with mlflow v1.28.0 #1298
Description
when run workflow:
qrun ALSTM_workflow_config_alstm_Alpha158.yaml
mlflow v1.27.0 work fine,but failed when with mlflow v1.28.0:

raise MlflowException(msg, INVALID_PARAMETER_VALUE)
mlflow.exceptions.MlflowException: Param value '[{'class': 'SignalRecord', 'module_path': 'qlib.workflow.record_temp', 'kwargs': {'model': '<MODEL>', 'dataset': '<DATASET>'}}, {'class': 'SigAnaRecord', 'module_path': 'qlib.workflow.record_temp', 'kwargs': {'ana_long_short': False, 'ann_scaler': 25' had length 778, which exceeded length limit of 500
i think the new mflow feature cause this bug.mlflow limit param valu lengh to 500,by read code ,it can not be overwrite.
maybe relate with this issue
