optimum-tpu 0.1.5

Optimum TPU is the interface between the Hugging Face Transformers library and Google Cloud TPU devices.

Optimum-TPU

Take the most out of Google Cloud TPUs with the ease of 🤗 transformers

Tensor Processing Units (TPU) are AI accelerator made by Google to optimize performance and cost from AI training to inference.

This repository exposes an interface similar to what Hugging Face transformers library provides to interact with a magnitude of models developed by research labs, institutions and the community.

We aim at providing our user the best possible performances targeting Google Cloud TPUs for both training and inference working closely with Google and Google Cloud to make this a reality.

Supported Model and Tasks

We currently support a few LLM models targeting text generation scenarios:

• 💎 Gemma (2b, 7b)
• 🦙 Llama2 (7b) and Llama3 (8b)
• 💨 Mistral (7b)

Installation

optimum-tpu comes with an handy PyPi released package compatible with your classical python dependency management tool.

pip install optimum-tpu -f https://storage.googleapis.com/libtpu-releases/index.html

Inference

optimum-tpu provides a set of dedicated tools and integrations in order to leverage Cloud TPUs for inference, especially on the latest TPU version v5e.

Other TPU versions will be supported along the way.

Text-Generation-Inference

As part of the integration, we do support a text-generation-inference (TGI) backend allowing to deploy and serve incoming HTTP requests and execute them on Cloud TPUs.

Please see the TGI specific documentation on how to get started

Training

Fine-tuning is supported and tested on the TPU v5e. We have tested so far:

• 🦙 Llama-2 7B and Llama-3 8B
• 💎 Gemma 2B and 7B

You can check the examples:

• Fine-Tune Gemma on Google TPU
