In Rails how do I use find_each method with index?

I can use Rails find_each method like :

User.find_each(:batch_size => 10000) do |user|
  ------
end 

With find_each method is there any way to get the index of the array ? like :

User.find_each(:batch_size => 10000).with_index do |user, index|
  ------
end
