Installation

Get your preferred distribution of OpenVINO or use this command for quick installation:

pip install -U openvino

Check system requirements and supported devices for detailed information.

Tutorials and Examples

OpenVINO Quickstart example will walk you through the basics of deploying your first model.

Learn how to optimize and deploy popular models with the OpenVINO Notebooks📚:

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

PyTorch Model

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

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.
