I used this test script.
$ cat test.rb
require "numo/linalg/autoloader"
require "datasets-numo-narray"
require "rumale"
p Numo::Linalg::Autoloader.libs
numeric_columns = [
:bill_length_mm, :bill_depth_mm, :flipper_length_mm, :body_mass_g
]
penguins = Datasets::Penguins.new
array = penguins.filter_map do |record|
values = numeric_columns.map do |column|
record[column]
end
unless values.include?(nil)
values
end
end
x = Numo::NArray[*array]
x_std = Rumale::Preprocessing::StandardScaler.new.fit_transform(x)
pca = Rumale::Decomposition::PCA.new#(n_components: 4)
p pca.fit_transform(x_std)
First, I confirmed that the problem occurs with liblapacke64.
$ ruby test.rb
["/usr/lib/x86_64-linux-gnu/libopenblas.so.0", "/usr/lib/x86_64-linux-gnu/liblapacke64.so.3.9.0"]

Then, I tried the same test script with liblapacke.
$ sudo apt remove liblapacke64
