Kubernetes Custom Resource and Operator for PyTorch jobs

⚠️ kubeflow/pytorch-operator is not maintained

This operator has been merged into Kubeflow Training Operator. This repository is not maintained and has been archived.

Build Status Go Report Card

Overview

This repository contains the specification and implementation of PyTorchJob custom resource definition. Using this custom resource, users can create and manage PyTorch jobs like other built-in resources in Kubernetes. See CRD definition

Prerequisites

Installing PyTorch Operator

Please refer to the installation instructions in the Kubeflow user guide. This installs pytorchjob CRD and pytorch-operator controller to manage the lifecycle of PyTorch jobs.

Creating a PyTorch Job

You can create PyTorch Job by defining a PyTorchJob config file. See the manifests for the distributed MNIST example. You may change the config file based on your requirements.

cat examples/mnist/v1/pytorch_job_mnist_gloo.yaml

Deploy the PyTorchJob resource to start training:

kubectl create -f examples/mnist/v1/pytorch_job_mnist_gloo.yaml

You should now be able to see the created pods matching the specified number of replicas.

kubectl get pods -l pytorch-job-name=pytorch-dist-mnist-gloo

Training should run for about 10 epochs and takes 5-10 minutes on a cpu cluster. Logs can be inspected to see its training progress.

PODNAME=$(kubectl get pods -l pytorch-job-name=pytorch-dist-mnist-gloo,pytorch-replica-type=master -o name)
kubectl logs -f ${PODNAME}

Monitoring a PyTorch Job

kubectl get -o yaml pytorchjobs pytorch-dist-mnist-gloo

See status section to monitor the job status. Here is sample output when the job is successfully completed.
