//! ML framework for Rust
//!
//! ```rust
//! use candle::{Tensor, DType, Device};
//! # use candle::Error;
//! # fn main() -> Result<(), Error>{
//!
//! let a = Tensor::arange(0f32, 6f32, &Device::Cpu)?.reshape((2, 3))?;
//! let b = Tensor::arange(0f32, 12f32, &Device::Cpu)?.reshape((3, 4))?;
//!
//! let c = a.matmul(&b)?;
//! # Ok(())}
//! ```
//!
//! ## Features
//!
//! - Simple syntax (looks and like PyTorch)
//! - CPU and Cuda backends (and M1 support)
//! - Enable serverless (CPU) small and fast deployments
//! - Model training
//! - Distributed computing (NCCL).
//! - Models out of the box (Llama, Whisper, Falcon, ...)
//!
//! ## FAQ
//!
//! - Why Candle?
//!
//! Candle stems from the need to reduce binary size in order to *enable serverless*
//! possible by making the whole engine smaller than PyTorch very large library volume
//!
//! And simply *removing Python* from production workloads.
//! Python can really add overhead in more complex workflows and the [GIL](https://www.backblaze.com/blog/the-python-gil-past-present-and-future/) is a notorious source of headaches.
//!
//! Rust is cool, and a lot of the HF ecosystem already has Rust crates [safetensors](https://github.com/huggingface/safetensors) and [tokenizers](https://github.com/huggingface/tokenizers)
