# Nx Sandbox
[](https://github.com/miolab/nx_sandbox)
Code sandbox for **Nx**.
> Nx is a multi-dimensional tensors library for Elixir with multi-staged compilation to the CPU/GPU.
> (https://github.com/elixir-nx/nx)
## Usage
### Set up (Elixir / Erlang OTP)
```sh
$ docker-compose build
```
#### **Usage** IEx
```sh
$ docker-compose up -d
```
```sh
$ docker-compose exec app iex
Erlang/OTP 24 [erts-12.0.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit]
Interactive Elixir (1.12.1) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>
```
### Set up (Nx)
- execute `mix new app_name`
```sh
$ docker-compose run --rm app mix new . --app my_app
Creating nx_sandbox_app_run ... done
* creating README.md
* creating .formatter.exs
* creating .gitignore
* creating mix.exs
* creating lib
* creating lib/my_app.ex
* creating test
* creating test/test_helper.exs
* creating test/my_app_test.exs
Your Mix project was created successfully.
You can use "mix" to compile it, test it, and more:
mix test
Run "mix help" for more commands.
```
- update file `mix.exs`
```elixir
defp deps do
[
{:nx, "~> 0.1.0-dev", github: "elixir-nx/nx", branch: "main", sparse: "nx"} # --> add
...
```
- execute `mix deps.get`
```sh
$ docker-compose run --rm app mix deps.get

$ docker-compose exec app iex -S mix
