[GitHub] [arrow] kou commented on pull request #14381: ARROW-17997: [Ruby] Add support for building Arrow::Tensor from raw nested Ruby array

   Thanks for the information.
   
   It seems that PyArrow only accepts constructing a tensor from a NumPy array: https://arrow.apache.org/docs/python/generated/pyarrow.Tensor.html#pyarrow.Tensor.from_numpy
   
   For Ruby, we're already providing a constructor from raw binary data and metadata. It's based on `arrow::Tensor::Make()` in C++. So we can't remove the constructor to keep backward compatibility.
   
   FYI: We have an external library that converts a NumPy like multi-dimentional array in Ruby (Numo::NArray) to `Arrow::Tensor`: https://github.com/red-data-tools/red-arrow-numo-narray/
