NodeSchool AI workshop

Getting started

Install Node.js (v18 recommended, check by running node -v in your terminal)
Install a code editor
- We recommend Visual Studio Code
Clone or download this project
- Download: https://github.com/pixelbar/nodeschool-ai/archive/refs/heads/main.zip
- Clone: git clone https://github.com/pixelbar/nodeschool-ai.git
Open the cloned directory in your code editor
Install dependencies
- Run in cloned directory: npm install
Download models
- If you're at Pixelbar, go to: http://172.16.31.216/ and download t5-base.zip and vit-base-patch16-224.zip, unzip them, and put them (the whole folder, not just the contents) in the models/Xenova folder.
- If you're not at Pixelbar, set allowRemoteModels in app.js to true to allow models to be downloaded at runtime.
If you want to use OpenAI, create an account at https://openai.com. You get $5 of free credits to be used in the first 3 months.
- Create an API key: https://platform.openai.com/account/api-keys
- Copy .env.example to .env and fill in the values
Run the app: node app.js

Note that Transformers.js is limited in that it can only run models that have been converted to a special format (ONNX). You can find all models compatible with Transformers.js here: https://huggingface.co/models?library=transformers.js&sort=downloads.
