TenfloweRS

A pure Rust implementation of TensorFlow, providing a comprehensive deep learning framework with Rust's safety and performance guarantees.

Overview

TenfloweRS is the main convenience crate that re-exports all TenfloweRS subcrates, providing a unified API for deep learning in Rust. Built on the robust SciRS2 ecosystem, it offers:

Production-Ready: Full-featured neural networks, training, and deployment
High Performance: GPU acceleration, SIMD optimization, mixed precision
Type Safety: Rust's type system prevents common ML bugs at compile time
Cross-Platform: CPU, GPU (CUDA, Metal, Vulkan), and WebGPU support
Ecosystem Integration: Seamless integration with SciRS2, NumRS2, and OptiRS

Quick Start

Add TenfloweRS to your Cargo.toml:

[dependencies]
tenflowers = "0.1.1"

Basic Example

use tenflowers::prelude::*;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create tensors
    let a = Tensor::<f32>::zeros(&[2, 3]);
    let b = Tensor::<f32>::ones(&[2, 3]);

    // Arithmetic operations
    let c = ops::add(&a, &b)?;

    // Matrix multiplication
    let x = Tensor::<f32>::ones(&[2, 3]);
    let y = Tensor::<f32>::ones(&[3, 4]);
    let z = ops::matmul(&x, &y)?;

    Ok(())
}

Build a Neural Network

use tenflowers::prelude::*;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a simple feedforward network
    let mut model = Sequential::new();
    model.add(Dense::new(784, 128)?);
    model.add_activation(ActivationFunction::ReLU);
    model.add(Dense::new(128, 10)?);
    model.add_activation(ActivationFunction::Softmax);

    // Forward pass
    let input = Tensor::zeros(&[32, 784]);
    let output = model.forward(&input)?;

    Ok(())
}

Train a Model

use tenflowers::prelude::*;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut model = Sequential::new();
    model.add(Dense::new(10, 64)?);
    model.add(Dense::new(64, 3)?);

    let x_train = Tensor::zeros(&[100, 10]);
    let y_train = Tensor::zeros(&[100, 3]);

    // Quick training
    let results = quick_train(
        model,
        &x_train,
        &y_train,
        Box::new(SGD::new(0.01)),
        categorical_cross_entropy,
        10,  // epochs
        32,  // batch_size
    )?;

    Ok(())
}
