A CPU runtime that takes advantage of sparsity within neural networks to reduce compute. Read more about sparsification [here](https://docs.neuralmagic.com/main/source/getstarted.html#sparsification).

Neural Magic's DeepSparse Engine is able to integrate into popular deep learning libraries (e.g., Hugging Face, Ultralytics) allowing you to leverage DeepSparse for loading and deploying sparse models with ONNX. ONNX gives the flexibility to serve your model in a framework-agnostic environment. Support includes [PyTorch,](https://pytorch.org/docs/stable/onnx.html) [TensorFlow,](https://github.com/onnx/tensorflow-onnx) [Keras,](https://github.com/onnx/keras-onnx) and [many other frameworks](https://github.com/onnx/onnxmltools).

The DeepSparse Engine is available in two editions:
1. [**The Community Edition**](#installation) is open-source and free for evaluation, research, and non-production use with our [Engine Community License](https://neuralmagic.com/legal/engine-license-agreement/).
2. [**The Enterprise Edition**](https://docs.neuralmagic.com/products/deepsparse-ent) requires a Trial License or [can be fully licensed](https://neuralmagic.com/legal/master-software-license-and-service-agreement/) for production, commercial applications.

## 🧰 Hardware Support and System Requirements

Review [CPU Hardware Support for Various Architectures](https://docs.neuralmagic.com/deepsparse/source/hardware.html) to understand system requirements.
The DeepSparse Engine works natively on Linux; Mac and Windows require running Linux in a Docker or virtual machine; it will not run natively on those operating systems.

The DeepSparse Engine is tested on Python 3.7-3.10, ONNX 1.5.0-1.12.0, ONNX opset version 11+, and manylinux compliant.
Using a [virtual environment](https://docs.python.org/3/library/venv.html) is highly recommended.

## Installation
The DeepSparse Engine is tested on Python 3.7-3.10, ONNX 1.5.0-1.12.0, ONNX opset version 11+, and manylinux compliant. Using a [virtual environment](https://docs.python.org/3/library/venv.html) is highly recommended. Install the engine using the following command:

Install the DeepSparse Community Edition as follows:

```bash
pip install deepsparse
```

## 🔌 DeepSparse Server
To trial or inquire about licensing for DeepSparse Enterprise Edition, see the [DeepSparse Enterprise documentation](https://docs.neuralmagic.com/products/deepsparse-ent).

## Features

### 🔌 DeepSparse Server

The DeepSparse Server allows you to serve models and pipelines from the terminal. The server runs on top of the popular FastAPI web framework and Uvicorn web server. Install the server using the following command:

```bash
pip install deepsparse[server]

Use Case: A workload that might benefit from the elastic scheduler is one in which multiple requests need to be handled simultaneously, but where performance is hindered when those requests have to share an L3 cache.

## 🧰 CPU Hardware Support

With support for AVX2, AVX-512, and VNNI instruction sets, the DeepSparse Engine is validated to work on x86 Intel (Haswell generation and later) and AMD CPUs running Linux. Mac and Windows require running Linux in a Docker or virtual machine.

Here is a table detailing specific support for some algorithms over different microarchitectures:
