This repo contains a cookiecutter template for running distributed training of deep learning models using Azure Machine Learning. You can create clusters with 0 nodes which will incur no cost and scale this up to hundreds of nodes. It is also possible to use low priority nodes to reduce costs even further.
The project contains the following:
This is a demo template that allows you to easily run tf_cnn_benchmarks on Azure ML. This is a great way to test performance as well as compare to other platforms
This is another demo template that shows you how to train a ResNet50 model using Imagenet on Azure. We include scripts for processing the Imagenet data, transforming them to TF Records as well as leveraging AzCopy to quickly upload the data to the cloud.
This is a blank template you can use for your own distributed training projects. It allows you to leverage all the tooling built around the previous two demos to speed up the time it takes to run your model in a distributed fashion on Azure.

Before you get started you need a PC running Ubuntu and the following installed:
Docker installed
Nvidia runtime for docker [Required for local execution]
Python>=3.6
Cookiecutter installed
Git installed
Note: You will need to run docker without sudo, to do this run:
sudo usermod -aG docker $USER newgrp docker
Once you have Cookiecutter installed you can either directly invoke project creation as follows:
cookiecutter gh:Microsoft/distributeddeeplearningor clone locally and then invoke
git clone https://github.com/Microsoft/distributeddeeplearning.git
cookiecutter distributeddeeplearningCookiecutter will then ask you about a number of fields which it will use to construct your project. If you simply want to select the defaults don't write or select anything just press enter. Many of them can be left at the default values, the ones that are absolutely necessary are highlighted
project_title: The title of your project
project_name: The folder in which your project will be created. Make sure it is a valid linux folder name
resource_group: The name of the resource group in Azure under which all the resources will be created. It is fine if it already exists
workspace: The AML workspace that the project will use. If it doesn't already exist it will create it
sub_id: The subscription id for your project, you can look this up on the portal or run a command on the cloud shell to get it. It isn't mandatory though, the application will give you an option to select it later.
vm_size: The VM type to use for distributed training
minimum_number_nodes: The minimum number of nodes in the cluster. Set to 0 if you want it to scale down after use to reduce costs
maximum_number_nodes: The maximum number of nodes in the cluster
cluster_name: The name of the cluster to use. It will create it if it doesn't exist
container_registry: The name of your dockerhub or other account which you may want to push your control plane docker container. If you don't have one or don't want to push the container to it simply leave as default
type: The type of project you want:
- all: All of them
- template: Just create a template for distributed training
- benchmark: Create project that will run the Tensorflow benchmarks
- imagenet: Create an example project that will run against the imagenet data. (You will need to download the imagenet data)
region: Which region to create Azure resources in
experiment_name: The name of the experiment
data: The absolute path on your computer where you will store the imagenet data. The location needs to have around 400GB of space
image_name: The name to give the control plane docker image
datastore_name: Name of the datastore that will be created as part of the project
container_name: The name of the container in your storage account that will hold the data
Once the project is created you will still be able to change many of the above options as they will be present in .env file that will be created.
Distributed training is complex and often has a number of moving parts. To reduce the overhead of installing packages and managing environments we use a docker container to encapsulate our enviroment. So once you have created the project simply navigate to the root folder created by cookiecutter and run:
make buildThis will build your docker container. Inside your docker container will be an appropriately set up conda environment a number of utilities such as AzCopy as well as everything you will need to run your distributed training job. Once your container is built run:
make runThis will put you in an environment inside your container in a tmux session (for a tutorial on tmux see here). The tmux control key has been mapped to ctrl+a rather than the standard ctrl+b so as not to interfere with outer tmux session if you are already a tmux user. You can alter this in the tmux.conf file in the Docker folder. The docker container will map the location you launched it from to the location /workspace inside the docker container. Therefore you can edit files outside of the container in the project folder and the changes will be reflected inside the container.
If you have selected all, tensorflow_imagenet or pytorch_imagenet in the type question during cookiecutter invocation then you will need to have ILSVRC2012_img_train.tar and ILSVRC2012_img_val.tar present in the direcotry you specified as your data directory. Go to the download page (you may need to register an account), and find the page for ILSVRC2012. You will need to download the two files mentioned earlier.
Based on the option you selected for type during the cookiecutter invocation you will get all or one of the options below. Cookiecutter will create your project folder which will contain the tempalte folders. When inside your project folder make sure you have run the make build and make run commands as mentioned in building environment section above. Once you run the run command you will be greeted by a prompt, this is now your control plane. First you will need to set everything up. To do this run
inv setup It will ask you to log in so follow the prompts in the terminal. If you selected all in the template type it will also prepare the imagenet data. Now you will be ready to run the templates.
This is a demo template allows you to easily run tf_cnn_benchmarks on Azure ML. This is a great way to test performance as well as compare to other platforms. To use this you must either select benchmark or all when invoking cookiecutter. Once setup is complete then simply run:
inv tf-benchmark.submit.local.syntheticto run things locally on a single GPU. Note that the first time you run things you will have to build the environment. To run things on a cluster simply run:
inv tf-benchmark.submit.remote.syntheticNote that this will create the cluster if it wasn't created earlier and create the appropriate environment.
This is the second demo template that will train a ResNet50 model on imagenet. It allows the options of using synthetic data, image data as well as tfrecords. To use this you must either select tensorflow_imagenet or all when cookiecutter asks what type of project you want to create. The run things locally using synthetic data simply run:
inv tf-imagenet.submit.local.synthetic
To run things on a remote cluster with real data in tfrecords format simply run:
inv tf-imagenet.submit.remote.tfrecords
This only covers a small number of commands, to see the full list of commands simply run inv --list.
This is the option that you should use if you want to run your own training script. It is up to you to add the appropriate training scripts and modify the tensorflow_experiment.py file to run the appropriate commands. If you want to see how to invoke things simply look at the other examples.
This is a demo template allows you to easily run a simple PyTorch benchmarking script on Azure ML. To use this you must either select benchmark or all when invoking cookiecutter. Once setup is complete then simply run:
inv pytorch-benchmark.submit.local.syntheticto run things locally on a single GPU. Note that the first time you run things you will have to build the environment. To run things on a cluster simply run:
inv pytorch-benchmark.submit.remote.syntheticNote that this will create the cluster if it wasn't created earlier and create the appropriate environment.
This is the second demo template that will train a ResNet50 model on imagenet. It allows the options of using synthetic data or image data. To use this you must either select pytorch_imagenet or all when cookiecutter asks what type of project you want to create. The run things locally using synthetic data simply run:
inv pytorch-imagenet.submit.local.synthetic
To run things on a remote cluster with real data in tfrecords format simply run:
inv pytorch-imagenet.submit.remote.tfrecords
This is the option that you should use if you want to run your own training script. It is up to you to add the appropriate training scripts and modify the pytorch_experiment.py file to run the appropriate commands. If you want to see how to invoke things simply look at the other examples.
Below is a diagram that shows how the project is set up.
The docker container you created using make build is the control plane and from there we can invoke jobs to execute either locally or in the cloud. Local execution is meant for debugging and will run on a single GPU. The mapping of data locations is handled by the control scripts. During local execution the appropriate location is mapped to the container. During remote execution the data store created during setup will be mounted on to each of the VMs in the cluster.
