Stack level too deep #24

Closed eichert12 closed 1 year ago

eichert12 commented 1 year ago

I'm getting a stack level too deep error in lib/eps/data_frame.rb when trying to train my model. The error is occuring at the values_at call on line 121 (https://github.com/ankane/eps/blob/master/lib/eps/data_frame.rb#L121) with the splat (*rows). The rows size is 130518 so perhaps larger than expected/supported?

  cols.each do |c|
    raise "Undefined column: #{c}" unless columns.include?(c)

    df.columns[c] = columns[c].values_at(*rows)
  end
