Can't execute workflow example

[summer980824]

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?

    config = yaml.safe_load(fp)

change import ruamel.yaml as yaml to import yaml if you has PyYAML installed.

change import ruamel.yaml as yaml to import yaml if you has PyYAML installed.

changed to import yaml still not working

change import ruamel.yaml as yaml to import yaml if you has PyYAML installed.

Thanks for your answer, it has fixed the yaml issue. But the program is stuck with ModuleNotFoundError errors now:

I think that lowering your ruamel.yaml version might solve the problem. Ref: https://github.com/microsoft/qlib/blob/main/setup.py#L77

change import ruamel.yaml as yaml to import yaml if you has PyYAML installed. and then change yaml.load to yaml.safe_load function

I have downgraded it to 0.17.36 and changed import ruamel.yaml back, but I still got the same ModuleNotFoundError.
