Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

ONNX runtime for node with gpu support (DirectML/Cuda)

Info

This is an updated copy of official onnxruntime-node with DirectML and Cuda support.

Requirements

Windows

  1. Works out of the box with DirectML. You can install CUDA and onnx runtime for windows with cuda provider for experiments, if you like.

Linux / WSL2

  1. Install CUDA (tested only on 11-7 but 12 should be supported) https://docs.nvidia.com/cuda/cuda-installation-guide-linux/
  2. Install onnxruntime-linux-x64-gpu-1.14.1 https://github.com/microsoft/onnxruntime/releases/tag/v1.14.1

Limitations

  1. Currently, all results are returned as NAPI nodejs objects, so when you run inference multiple times (e.g. sampling on StableDiffusion Unet), there are a lot of unnecessary memory copy operations input from js to gpu and back. However, performance impact is not big. Maybe later I will make output in Tensorflow.js compatible tensors

Building manually

Just download the repo and run npx cmake-js compile

Why is onnxruntime statically linked on Windows?

For some reason, dynamically linked onnx runtime tries to load outdated DirectML.dll in system32, see https://github.com/royshil/obs-backgroundremoval/issues/272

Misc

Special thanks to authors of https://github.com/royshil/obs-backgroundremoval and https://github.com/umireon/onnxruntime-static-win for CMake scripts to download pre-built onnxruntime for static linking.

Also thanks to ChatGPT for helping me to remember how to code in c++.
