Numo::NArray.zeros() - allocator undefined for Numo::NArray (TypeError)

[ghost]

In ruby I call: @vector_dimension=50 66: sum_vector = Numo::NArray.zeros(@vector_dimension)

i get this vector_model_loader.rb:66:in `zeros': allocator undefined for Numo::NArray (TypeError)

sum_vector = Numo::NArray.zeros(@vector_dimension)
                                ^^^^^^^^^^^^^^^^^

Same with ruby 3.4.4 as 3.2.8. Tried downgrading to 0.9.2.0 doesnt compile. 0.9.1 is for ruby 2.1
