2.3. Tutorial on BERT Fine-tuning on IPU

This tutorial demonstrates how to fine-tune a pre-trained BERT model with PyTorch on the Graphcore IPU-POD16 system. It uses a BERT-Large model and fine-tunes it on the SQuADv1 Question/Answering task. The tutorial is in Fine-tuning-BERT.ipynb.

  • README.md This file;

  • Fine-tuning-BERT.ipynb The tutorial jupyter notebook;

  • Fine-tuning-BERT.py Python script conversion of the jupyter notebook;

  • squad_preprocessing.py Contains a number of utility functions to prepare the data;

  • requirements.txt Required packages;

How to use this demo

  1. Prepare the PopTorch environment.

    Install the Poplar SDK following the instructions in the Getting Started guide for your IPU system. Make sure to run the enable.sh script for Poplar and activate a Python virtualenv with a PopTorch wheel from the Poplar SDK installed (use the version appropriate to your operating system).

  2. Install the required packages:

    pip install -r requirements.txt
    
  3. Run the jupyter notebook and connect to it with your browser. You may need to use an SSH tunnel to tunnel jupyter back to your local machine using: ssh -L 8888:localhost:8888 [REMOTE-IPU-MACHINE] -N.
