Tensorflow with GPUs

Example on how to use Tensorflow library with GPUs

Last updated 16th January, 2021.

Objective

This tutorial covers the proccess of starting a new Jupyter notebook and experiment examples on using GPUs with it.

Requirements

Launch and access Jupyter notebook with Tensorflow library

If you want to launch it from the OVHcloud Control Panel, just follow this guide and select the Tensorflow 2 docker image.

If you want to launch it with the CLI, just choose the number of GPUs (<nb-gpus>) to use on jour job and use the following command:

ovhai job run ovhcom/ai-training-tensorflow:2.3.0 --gpu <nb-gpus>

You can then reach your notebook's URL once the job is Running.

Clone the GitHub example repository

The GitHub repository containing all examples for OVHcloud AI TRAINING is available here.

Inside your notebook, open a new Terminal tab by clicking File > New > Terminal.

Run the following command in the notebook's terminal to clone the repository:

git clone https://github.com/ovh/ai-training-examples.git

Experiment with examples notebooks

We currently provide the following tutorials for Tensorflow as ipython notebooks:

  • Basic computation using single CPU or GPU: accessible on notebooks/tensorflow/tuto/basic_gpu_cpu_benchmark.ipynb
  • Basic computation using multiple GPUs: accessible on notebooks/tensorflow/tuto/multiple_gpus_computation.ipynb.ipynb

Basic computation using a single CPU or GPU

The aim of this tutorial is to do a very simple tensor computation with the Tensorflow library and to compare performances of running it over CPU versus GPU.

A preview of this notebook can be found on GitHub here.
