Welcome to OpenVINO™, an open-source software toolkit for optimizing and deploying deep learning models.



- **Inference Optimization**: Boost deep learning performance in computer vision, automatic speech recognition, generative AI, natural language processing with large and small language models, and many other common tasks.

- **Flexible Model Support**: Use models trained with popular frameworks such as TensorFlow, PyTorch, ONNX, Keras, and PaddlePaddle. Convert and deploy models without original frameworks.

- **Broad Platform Compatibility**: Reduce resource demands and efficiently deploy on a range of platforms from edge to cloud. OpenVINO™ supports inference on CPU (x86, ARM), GPU (OpenCL capable, integrated and discrete) and AI accelerators (Intel NPU).

- **Community and Ecosystem**: Join an active community contributing to the enhancement of deep learning performance across various domains.



Check out the [OpenVINO Cheat Sheet](https://docs.openvino.ai/2024/_static/download/OpenVINO_Quick_Start_Guide.pdf) for a quick reference.



## Installation



[Get your preferred distribution of OpenVINO](https://docs.openvino.ai/2024/get-started/install-openvino.html) or use this command for quick installation:



```sh

pip install -U openvino

```



Check [system requirements](https://docs.openvino.ai/2024/about-openvino/system-requirements.html) and [supported devices](https://docs.openvino.ai/2024/about-openvino/compatibility-and-support/supported-devices.html) for detailed information.



## Tutorials and Examples



[OpenVINO Quickstart example](https://docs.openvino.ai/2024/get-started.html) will walk you through the basics of deploying your first model.



Learn how to optimize and deploy popular models with the [OpenVINO Notebooks](https://github.com/openvinotoolkit/openvino_notebooks)📚:

- [YOLOv8 Optimization](https://github.com/openvinotoolkit/openvino_notebooks/blob/latest/notebooks/quantizing-model-with-accuracy-control/yolov8-quantization-with-accuracy-control.ipynb)

- [Text-to-Image Generation](https://github.com/openvinotoolkit/openvino_notebooks/blob/latest/notebooks/controlnet-stable-diffusion/controlnet-stable-diffusion.ipynb)



Here are easy-to-follow code examples demonstrating how to run PyTorch and TensorFlow model inference using OpenVINO:



**PyTorch Model**



```python

import openvino as ov

import torch

import torchvision



# load PyTorch model into memory

model = torch.hub.load("pytorch/vision", "shufflenet_v2_x1_0", weights="DEFAULT")



# convert the model into OpenVINO model

example = torch.randn(1, 3, 224, 224)

ov_model = ov.convert_model(model, example_input=(example,))



# compile the model for CPU device

core = ov.Core()

compiled_model = core.compile_model(ov_model, 'CPU')



# infer the model on random data

output = compiled_model({0: example.numpy()})

```



**TensorFlow Model**



```python

import numpy as np

import openvino as ov

import tensorflow as tf



# load TensorFlow model into memory

model = tf.keras.applications.MobileNetV2(weights='imagenet')



# convert the model into OpenVINO model

ov_model = ov.convert_model(model)



# compile the model for CPU device

core = ov.Core()

compiled_model = core.compile_model(ov_model, 'CPU')



# infer the model on random data

data = np.random.rand(1, 224, 224, 3)

output = compiled_model({0: data})

```



OpenVINO also supports CPU, GPU, and NPU devices and works with models in TensorFlow, PyTorch, ONNX, TensorFlow Lite, PaddlePaddle model formats.

With OpenVINO you can do automatic performance enhancements at runtime customized to your hardware (preserving model accuracy), including:

asynchronous execution, batch processing, tensor fusion, load balancing, dynamic inference parallelism, automatic BF16 conversion, and more.
