Can't execute workflow example

Hi, I got below error by executing the example workflow in the readme. I am using python 3.8.18. Could you help with it?

(qlib) D:\Work\workspace\qlib\examples>qrun benchmarks/LightGBM/workflow_config_lightgbm_Alpha158.yaml

    config = yaml.safe_load(fp)

Start with qlib/workflow/cli.py at line 71 and the README workflow example that runs qrun benchmarks/LightGBM/workflow_config_lightgbm_Alpha158.yaml. Reproduce the failure with the reported Python environment, inspect the ruamel.yaml safe_load compatibility error, and verify that the example workflow executes successfully afterward.
