Intel® Neural Compressor aims to provide popular model compression techniques such as quantization, pruning (sparsity), distillation, and neural architecture search on mainstream frameworks such as TensorFlow, PyTorch, ONNX Runtime, and MXNet, as well as Intel extensions such as Intel Extension for TensorFlow and Intel Extension for PyTorch. In particular, the tool provides the key features, typical examples, and open collaborations as below:

• Support a wide range of Intel hardware such as Intel Xeon Scalable Processors, Intel Xeon CPU Max Series, Intel Data Center GPU Flex Series, and Intel Data Center GPU Max Series with extensive testing; support AMD CPU, ARM CPU, and NVidia GPU through ONNX Runtime with limited testing

• Validate popular LLMs such as LLama2, Falcon, GPT-J, Bloom, OPT, and more than 10,000 broad models such as Stable Diffusion, BERT-Large, and ResNet50 from popular model hubs such as Hugging Face, Torch Vision, and ONNX Model Zoo, by leveraging zero-code optimization solution Neural Coder and automatic accuracy-driven quantization strategies

• Collaborate with cloud marketplaces such as Google Cloud Platform, Amazon Web Services, and Azure, software platforms such as Alibaba Cloud, Tencent TACO and Microsoft Olive, and open AI ecosystem such as Hugging Face, PyTorch, ONNX, ONNX Runtime, and Lightning AI

Getting Started

Quantization with Python API

# Install Intel Neural Compressor and TensorFlow
pip install neural-compressor
pip install tensorflow
# Prepare fp32 model
wget https://storage.googleapis.com/intel-optimized-tensorflow/models/v1_6/mobilenet_v1_1.0_224_frozen.pb

from neural_compressor.data import DataLoader, Datasets
from neural_compressor.config import PostTrainingQuantConfig

dataset = Datasets("tensorflow")["dummy"](shape=(1, 224, 224, 3))
dataloader = DataLoader(framework="tensorflow", dataset=dataset)

from neural_compressor.quantization import fit

q_model = fit(
    model="./mobilenet_v1_1.0_224_frozen.pb",
    conf=PostTrainingQuantConfig(),
    calib_dataloader=dataloader,
)
