# README

## Name

Red Arrow Numo::NArray

## Description

Red Arrow Numo::NArray is a library that provides converters between Apache Arrow's tensor data (`Arrow::Tensor`) and Numo::NArray data.

Red Arrow Numo::NArray adds `Arrow::Tensor#to_narray` and `#to_arrow`/`#to_arrow_array` to `Numo::NArray`'s numerical subclasses such as `Numo::Int8`. `Arrow::Tensor#to_narray` returns a `Numo::NArray`'s numerical subclass such as `Numo::Int8`. `#to_arrow` returns a `Arrow::Tensor`. `#to_arrow_array` returns an `Arrow::Array` instance if the original object is an 1 dimensional array.

## Install

```text
% gem install red-arrow-numo-narray
```

## Usage

```ruby
require "arrow-numo-narray"

tensor.to_narray # -> An object of Numo::NArray's numeric subclass such as Numo::Int8
narray.to_arrow # -> An object of Arrow::Tensor
```
