Burn Torch Backend

Burn Torch backend

This crate provides a Torch backend for Burn utilizing the tch-rs crate, which offers a Rust interface to the PyTorch C++ API.

The backend supports CPU (multithreaded), CUDA (multiple GPUs), and MPS devices (MacOS).

Usage Example

#[cfg(feature = "tch-gpu")]
mod tch_gpu {
    use burn_autodiff::ADBackendDecorator;
    use burn_tch::{TchBackend, TchDevice};
    use mnist::training;

    pub fn run() {
        #[cfg(not(target_os = "macos"))]
        let device = TchDevice::Cuda(0);
        #[cfg(target_os = "macos")]
        let device = TchDevice::Mps;

        training::run::<ADBackendDecorator<TchBackend<f32>>>(device);
    }
}

#[cfg(feature = "tch-cpu")]
mod tch_cpu {
    use burn_autodiff::ADBackendDecorator;
    use burn_tch::{TchBackend, TchDevice};
    use mnist::training;

    pub fn run() {
        let device = TchDevice::Cpu;
        training::run::<ADBackendDecorator<TchBackend<f32>>>(device);
    }
}
