Additional Notes

Start with qlib/contrib/data/handler.py at line 171 and reproduce the failure by running workflow_by_code.ipynb through the training segment. Determine what input causes the delimiter TypeError; done means the Alpha158 initialization and notebook workflow proceed without that exception.
