Pytorch rust: A library for machine learning in Rust

Pytorch Rust: An Overview




Pytorch Rust is a set of Rust bindings for the C++ API of PyTorch. It provides an API that is very close to that of PyTorch, allowing developers to use the power of PyTorch in their Rust applications.

What is Pytorch Rust?

Pytorch Rust, also known as tch-rs, is a library that provides thin wrappers around the C++ API of PyTorch. The goal of tch-rs is to stay as close as possible to the original C++ API, while providing more idiomatic Rust bindings on top of it.

Why use Pytorch Rust?

There are several benefits to using Pytorch Rust in your applications. Some of these benefits include: Performance: Rust is known for its performance and memory safety, making it a great choice for high-performance applications. Deployment: Deploying PyTorch models can be difficult, but using tch-rs can make it easier to deploy your models in production. Web frameworks: Popular web frameworks from Rust, such as Rocket and Actix, are gaining traction in the web community. Using tch-rs allows you to integrate your PyTorch models with these frameworks.

Getting Started with Pytorch Rust

To get started with Pytorch Rust, you will need to have the C++ PyTorch library (libtorch) installed on your system. You can either use a system-wide installation, install libtorch manually and set the LIBTORCH environment variable, or use a Python PyTorch install by setting the LIBTORCH_USE_PYTORCH environment variable. Once you have libtorch installed, you can add tch-rs as a dependency in your Cargo.toml file and start using it in your code.

Examples

Here are some examples of how you can use Pytorch Rust in your code: Loading a trained model: use tch::{nn, Device}; let vs = nn::VarStore::new(Device::Cpu); let model = MyModel::load(&vs, "model.pt")?; Running inference on an input tensor: let input = Tensor::from_slice(&[1.0, 2.0, 3.0]); let output = model.forward(&input);

Conclusion

Pytorch Rust is a powerful tool that allows developers to use the power of PyTorch in their Rust applications. With its performance and ease of deployment, it is a great choice for anyone looking to integrate machine learning into their applications.
