Run Your First Experiment in Determined#

In this tutorial, we’ll show you how to integrate a training example with the Determined environment. We’ll run our experiment on a local training environment requiring only a single CPU or GPU.


This tutorial is recommended as an introduction for model developers who are new to Determined AI.


Our goal is to integrate the PyTorch MNIST training example into Determined in four steps:

  • Download and extract the files

  • Set up our training environment

  • Run the experiment

  • View the experiment in our browser


Download the Files#

To get started, we’ll first download and extract the files we need and cd into the directory.

  • Download the mnist_pytorch.tgz file.

  • Open a terminal window, extract the files, and cd into the mnist_pytorch directory:

tar xzvf mnist_pytorch.tgz
cd mnist_pytorch

Set Up Your Training Environment#

To start your experiment, you’ll need a Determined cluster. If you are new to Determined AI (Determined), you can install the Determined library and start a cluster locally:

pip install determined

# If your machine has GPUs:
det deploy local cluster-up

# If your machine does not have GPUs:
det deploy local cluster-up --no-gpu


The command, pip install determined, installs the determined library which includes the Determined command-line interface (CLI).

Run the Experiment#

To run the experiment, enter the following command:

det experiment create const.yaml . -f

A notification displays letting you know the experiment has started.

Preparing files (.../mnist_pytorch) to send to master...
Created experiment xxx

View the Experiment#

To view the experiment progress in your browser:

  • Enter the following URL: http://localhost:8080/.

This is the cluster address for your local training environment.

  • Accept the default username of determined, and click Sign In. A password is not required.

Next Steps#

In four simple steps, we’ve successfully configured our training environment in Determined to start training the PyTorch MNIST example.
