run the ML method ------metadata.yaml not found

[wencyxu]

When I run "python analyze.py /root/SP500/B1.tsv.gz -ml 'AdaBoostRegressor", it shows:Metadata file /root/SP500/metadata.yaml not found, skipping dataset /root/SP500/B1.tsv.gz. How do I run the ML method, please? Thanks a lot!!!!

1. what version are you using? (recommend release)
2. analyze.py expects a dataset directory, not a single data file. and it expects to submit to a cluster unless you pass --local flag.

Thank you so much for receiving your reply ~ I have one more small question. As shown in the picture, I entered a dataset directory (containing tsv.gz and metadata.yaml), but it shows that the folder does not have a dataset.

have you cloned the pmlb repository using git-lfs?

No, I haven't. Because I wanted to use my own dataset instead of PMLB.

pmlb/datasets looks like this: https://github.com/EpistasisLab/pmlb/tree/master/datasets

i.e., put your data in a data folder, and pass the parent folder.

if you aren't using the release version you may run into other issues.
