Hidet: An Open-Source Deep Learning Compiler

Documentation | Research Paper | Releases | Contributing

Hidet is an open-source deep learning compiler, written in Python. It supports end-to-end compilation of DNN models from PyTorch and ONNX to efficient cuda kernels. A series of graph-level and operator-level optimizations are applied to optimize the performance.

Currently, hidet focuses on optimizing the inference workloads on NVIDIA GPUs, and requires

• Linux OS
• CUDA Toolkit 11.6+
• Python 3.9+

Getting Started

Installation

If you are going to use hidet's API

pip install hidet

If you are going to use hidet as PyTorch compiler

pip install hidet[torch]

You can also try the nightly build version or build from source.

Usage

Optimize a PyTorch model through hidet (require PyTorch 2.3):

import torch

# Define pytorch model
model = torch.hub.load('pytorch/vision:v0.6.0', 'resnet18', pretrained=True).cuda().eval()
x = torch.rand(1, 3, 224, 224).cuda()

# Compile the model through Hidet
# Optional: set optimization options (see our documentation for more details)
#   import hidet 
#   hidet.torch.dynamo_config.search_space(2)  # tune each tunable operator
model_opt = torch.compile(model, backend='hidet')  

# Run the optimized model
y = model_opt(x)
