If we create a row data frame with only 1 row, but it has multi-index it works
> df1 = Daru::DataFrame.new( { 'Beer' => ['Kingfisher'] , 'Gallons sold' => [500 ] }, :index => [[ 'Asia', 'india'] ] ) => #<Daru::DataFrame(1x2)> Beer Gallons so Asia india Kingfisher 500
If we have a data frame with only 1 row, and if we try to raise a single index it also works.
> df2 = Daru::DataFrame.new( { 'Beer' => ['Kingfisher'] , 'Gallons sold' => [500 ], 'Country' => [ 'india' ], 'Continent' => ['Asia'] }) => #<Daru::DataFrame(1x4)> Beer Gallons so Country Continent 0 Kingfisher 500 india Asia > df2.set_index('Continent') => #<Daru::DataFrame(1x3)> Beer Gallons so Country Asia Kingfisher 500 india
However, if we try to set a multi-index when the data frame size is 1, it fails deterministically
> df3 = Daru::DataFrame.new( { 'Beer' => ['Kingfisher'] , 'Gallons sold' => [500 ], 'Country' => [ 'india' ], 'Continent' => ['Asia'] }) => #<Daru::DataFrame(1x4)> Beer Gallons so Country Continent 0 Kingfisher 500 india Asia > df3.set_index( ['Continent', 'Country'] ) Traceback (most recent call last): 5: from /Users/Dipan/.rvm/rubies/ruby-2.6.3/bin/irb:23:in `<main>' 4: from /Users/Dipan/.rvm/rubies/ruby-2.6.3/bin/irb:23:in `load' 3: from /Users/Dipan/.rvm/rubies/ruby-2.6.3/lib/ruby/gems/2.6.0/gems/irb-1.0.0/exe/irb:11:in `<top (required)>' 2: from (irb):11 1: from /Users/Dipan/.rvm/gems/ruby-2.6.3/gems/daru-0.2.2/lib/daru/dataframe.rb:1577:in `set_index'
Trying to add indexes one by one also fails.
