LLaMA

This repository is intended as a minimal, hackable and readable example to load LLaMA (arXiv) models and run inference. In order to download the checkpoints and tokenizer, fill this google form

Run in a Free GPU powered Gradient Notebook

Gradient

Setup

In a conda env with pytorch / cuda available, run:

pip install -r requirements.txt

Download

Once your request is approved, you will receive links to download the tokenizer and model files. Edit the download.sh script with the signed url provided in the email to download the model weights and tokenizer.

In Gradient

If you are working in a Gradient Notebook, then these models have been uploaded for you, and mounted to your Notebook automatically. The path to the model files from the notebooks working directory:

../datasets/llama/

Inference

Gradio App

To run the Gradio Application, run the following in the terminal or using line magic. The MP values will automatically be connected. Note that multi-gpu machines are likely necessary to run 13B (x2), 30B (x4), and 65B (x8) models.

python app.py

Original script

The provided example.py can be run on a single or multi-gpu node with torchrun and will output completions for two pre-defined prompts. Using TARGET_FOLDER as defined in download.sh:

torchrun --nproc_per_node MP example.py --ckpt_dir $TARGET_FOLDER/$MODEL_SIZE --tokenizer_path $TARGET_FOLDER/tokenizer.model --prompt <your prompt> --seed 42

Different models require different MP values:

Model MP
7B 1
13B 2
33B 4
65B 8
