Hi All,
I am trying to blindly use JLBoost on a big dataset with 2381 features and 600 000 samples. I have automatically converted the feature matrix to the DataFrame using df = DataFrame(x, :auto), add labels as df.y = y, and then I started to fit the model with default settings
julia> xgtreemodel = jlboost(df, :y)
this branch has too few records
this branch has too few records
ERROR: KeyError: key not found

Can anyone give me hint, what might went wrong?
Thanks a lot,
