2//! # Tract TensorFlow module
3//!
4//! Tiny, no-nonsense, self contained, portable inference.
5//!
6//! ## Example
7//!
8//! ```
9//! # extern crate tract_tensorflow;
10//! # fn main() {
11//! use tract_tensorflow::prelude::*;
12//!
13//! // build a simple model that just add 3 to each input component
14//! let tf = tensorflow();
15//! let mut model = tf.model_for_path("tests/models/plus3.pb").unwrap();
16//!
17//! // set input input type and shape, then optimize the network.
18//! model.set_input_fact(0, f32::fact(&[3]).into()).unwrap();
19//! let model = model.into_optimized().unwrap();
20//!
21//! // we build an execution plan. default input and output are inferred from
22//! // the model graph
23//! let plan = SimplePlan::new(&model).unwrap();
24//!
25//! // run the computation.
26//! let input = tensor1(&[1.0f32, 2.5, 5.0]);
27//! let mut outputs = plan.run(tvec![input]).unwrap();
28//!
29//! // take the first and only output tensor
30//! let mut tensor = outputs.pop().unwrap();
31//!
32//! assert_eq!(tensor, rctensor1(&[4.0f32, 5.5, 8.0]));
33//! # }
34//! ```
