Jul 6, 2025

Introduction

T5X is an innovative project developed by Google Research that facilitates the deployment of advanced Natural Language Processing (NLP) models on TPU (Tensor Processing Unit) virtual machines. This blog post will guide you through the essential features, installation process, and usage of T5X, enabling you to leverage its capabilities for your machine learning projects.

Features

  • Custom Jupyter Kernel: Easily create a custom Jupyter kernel/runtime via Google Cloud TPU VM.
  • Seamless Integration: Connect to local runtimes for running notebooks effortlessly.
  • Comprehensive Setup Guide: Detailed instructions for setting up TPU VMs and Python environments.
  • Advanced NLP Models: Support for state-of-the-art NLP models, enhancing your machine learning capabilities.

Installation

To get started with T5X, follow these steps:

  1. Set up a GCP account and follow the installation guide.
  2. Create a TPU VM using the command below:
  3. export TPUVMNAME=xxxx;
    export TPUVMZONE=xxxxxxx;
    export TPUTYPE=v3-8;
    export APIVERSION=v2-alpha
    
    gcloud alpha compute tpus tpu-vm create ${TPUVMNAME} --zone=${TPUVMZONE} --accelerator-type=${TPUTYPE} --version=${APIVERSION}
  4. Set proper firewall rules to allow SSH access:
  5. gcloud compute firewall-rules create default-allow-ssh --allow tcp:22
  6. SSH into the TPU VM:
  7. gcloud compute tpus tpu-vm ssh ${TPUVMNAME} --zone=${TPUVMZONE} -- -L 8888:localhost:8888
  8. Create a Python environment:
  9. sudo apt update
    sudo apt install -y python3.9 python3.9-venv
    python3.9 -m venv t5_venv
  10. Install T5X and its dependencies:
  11. source t5_venv/bin/activate
    python3 -m pip install -U pip setuptools wheel ipython
    pip install flax
    git clone --branch=main https://github.com/google-research/t5x
    cd t5x
    python3 -m pip install -e '.[tpu]' -f https://storage.googleapis.com/jax-releases/libtpu_releases.html
    cd -
  12. Verify TPU access:
  13. python3 -c "import jax; print(jax.local_devices())"
  14. Prepare necessary packages for Jupyter:
  15. pip install notebook
    pip install --upgrade jupyter_http_over_ws>=0.0.7
    jupyter serverextension enable --py jupyter_http_over_ws
  16. Launch the Jupyter runtime:
  17. jupyter notebook --NotebookApp.allow_origin='https://colab.research.google.com' --port=8888 --NotebookApp.port_retries=0

Usage

Once your environment is set up, you can connect to your local runtime from Google Colab. Simply copy the HTTP link generated by the Jupyter command and paste it into the Connect to a local runtime option in Colab. This allows you to run T5X notebooks seamlessly.

Benefits

  • Enhanced Performance: Leverage TPU’s capabilities for faster model training and inference.
  • Scalability: Easily scale your machine learning workloads with TPU VMs.
  • Community Support: Engage with a community of developers and researchers working on cutting-edge NLP technologies.
