Imagine a bustling library where everyone shares their books, enabling readers to access volumes that would otherwise be out of reach. This is akin to running large language models (LLMs) at home using a collaborative system like Petals, where you can fine-tune and infer from models such as Llama 3.1, Mixtral, Falcon, or BLOOM right from your desktop or Google Colab. In this guide, we’ll walk you through the steps to set up your environment, making the entire process user-friendly.
Getting Started
To kick off the process of running large language models at home, first, ensure you have a compatible setup. Follow these steps:
- Ensure you have Python installed on your machine.
- Set up a Conda or virtual environment.
- Install the required packages using the commands outlined below.
Step-by-Step Guide to Fine-Tuning and Inference
Using the Petals library, fine-tuning and inference become a breeze. Here is a code analogy to simplify the process:
Think of your computer as a chef in a restaurant, preparing a unique dish (the output) using multiple ingredients (the models). Sometimes, these ingredients may come from different kitchens (distributed models). Instead of relying on a single kitchen for all ingredients, this method allows the chef to source them collaboratively, resulting in a delicious dish delivered faster and with less hassle.
Code Implementation
Here’s how you can set up and run your model:
python
from transformers import AutoTokenizer
from petals import AutoDistributedModelForCausalLM
# Choose any model available at https://health.petals.dev
model_name = "meta-llama/Meta-Llama-3.1-405B-Instruct"
# Connect to a distributed network hosting model layers
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoDistributedModelForCausalLM.from_pretrained(model_name)
# Run the model as if it were on your computer
inputs = tokenizer("A cat sat", return_tensors="pt")
outputs = model.generate(inputs, max_new_tokens=5)
print(tokenizer.decode(outputs[0])) # A cat sat on a mat...
Replace meta-llama/Meta-Llama-3.1-405B-Instruct with any other model of your choice available in the Petals library.
Connecting Your GPU
Sharing is caring in the world of Petals! To enhance the capacity of the Petals system, connect your GPU. This way, you not only contribute to the community but also speed up the processing significantly.
Hosting the Model Example
Here’s how you can host Llama 3.1 (405B) on your GPU:
- Linux + Anaconda:
bash conda install pytorch pytorch-cuda=11.7 -c pytorch -c nvidia pip install git+https://github.com/bigscience-workshop/petals python -m petals.cli.run_server meta-llama/Meta-Llama-3.1-405B-Instruct - Windows + WSL: Follow our guide.
Troubleshooting and Support
If you encounter issues while running the setup, here are some troubleshooting tips:
- Ensure your GPU drivers are updated.
- Verify that all required libraries are installed correctly.
- Check network connectivity to the distributed system.
- If you’re still having trouble, consider pinging us in our Discord for help.
