PyTorch Distributed Data Parallel (DDP)

This example shows how to use Distributed Data Parallel (DDP) with PyTorch on Azure Machine Learning.

Prerequisites

• Azure Machine Learning Workspace
  • Compute Clusters with GPU for distributed training
  • Compute Instance with Azure ML CLI 2.0 installed

Getting Started

1. Create training data from python scirpt that create data folder.

   python dataprep.py
   

2. Create a job (Azure ML CLI 2.0 + YML configuration file) from VSCode Azure ML Extension.

   cd examples/train/pytorch-ddp/
   az ml job create --file job.yml --stream
   

3. Access to Azure ML studio and see Experiment logs.

• In Experiment, paramters & metrics is logged. And you can check system performance in Monitoring tab like below.
