4//! # Tract
5//!
6//! Tiny, no-nonsense, self contained, portable TensorFlow and ONNX inference.
7//!
8//! ## Example
9//!
10//! ```
11//! # extern crate tract_core;
12//! # fn main() {
13//! use tract_core::internal::*;
14//!
15//! // build a simple model that just add 3 to each input component
16//! let mut model = TypedModel::default();
17//!
18//! let input_fact = f32::fact(&[3]);
19//! let input = model.add_source("input", input_fact).unwrap();
20//! let three = model.add_const("three".to_string(), tensor1(&[3f32])).unwrap();
21//! let add = model.wire_node("add".to_string(),
22//!     tract_core::ops::math::add(),
23//!     [input, three].as_ref()
24//!     ).unwrap();
25//!
26//! model.auto_outputs().unwrap();
27//!
28//! // We build an execution plan. Default inputs and outputs are inferred from
29//! // the model graph.
30//! let plan = SimplePlan::new(&model).unwrap();
31//!
32//! // run the computation.
33//! let input = tensor1(&[1.0f32, 2.5, 5.0]);
34//! let mut outputs = plan.run(tvec![input.into()]).unwrap();
35//!
36//! // take the first and only output tensor
37//! let mut tensor = outputs.pop().unwrap();
38//!
39//! assert_eq!(tensor, tensor1(&[4.0f32, 5.5, 8.0]).into());
40//! # }
41//! ```
42//!
43//! While creating a model from Rust code is useful for testing the library,
44//! real-life use-cases will usually load a TensorFlow or ONNX model using
45//! tract-tensorflow or tract-onnx crates.
