Is there any codes to dump features?

[BigAndSweet]

I try examples/data_demo/data_cache_demo.py with benchmarks/TRA/workflow_config_tra_Alpha158.yaml, and only get handler.pkl. It is only an object of class Alpha158 rather than the features. I want to dump the features into local disk, but I did not find any document to support it.

If you want to dump the data into a bin file supported by qlib, you can refer to step 3 in this document.
