Stable Diffusion XL 1.0 TensorRT

Introduction

This repository hosts the TensorRT versions(sdxl, sdxl-lcm, sdxl-lcmlora) of Stable Diffusion XL 1.0 created in collaboration with NVIDIA. The optimized versions give substantial improvements in speed and efficiency.

See the usage instructions for how to run the SDXL pipeline with the ONNX files hosted in this repository.

1.Install libraries and requirements

shell

cd demo/Diffusion
python3 -m pip install --upgrade pip
pip3 install -r requirements.txt
python3 -m pip install --pre --upgrade --extra-index-url https://pypi.nvidia.com tensorrt

1.Perform TensorRT optimized inference:

—SDXL

The first invocation produces plan files in engine_xl_base and engine_xl_refiner specific to the accelerator being run on and are reused for later invocations.
