I'm trying to run kmeans-clusterer with narray in Ruby. But when it comes to this line in narray_ext.rb:
na = self.new(type,*shape)
I get this error:
narray_ext.rb:21:in new': Argument required (ArgumentError)
I'm using these gems:
- kmeans-clusterer-0.11.4
- narray-0.6.1.2
- zombie_writer-0.2.0
Stacktrace:

And my code:
require 'zombie_writer'
zombie = ZombieWriter::MachineLearning.new
zombie.add_string(content: "Lorem ipsum dolor sit amet.",
sourcetext: "Cicero's Great Speech On Ethics",
sourceurl: "http://example.com/lorem-ipsum")
array = zombie.generate_articles
Fairly new to Ruby myself, and I can't figure it out, so. Does anyone know what is going on and how I can fix it?
This was resolved for me by the developer of ZombieWriter. Read the developers reply on the issue on Github if you have the same problem.
