Starting from v1.3, this training operator provides Kubernetes custom resources that makes it easy to run distributed or non-distributed TensorFlow/PyTorch/Apache MXNet/XGBoost/MPI jobs on Kubernetes.
Note: Before v1.2 release, Kubeflow Training Operator only supports TFJob on Kubernetes.
- For a complete reference of the custom resource definitions, please refer to the API Definition.
- For details on API design, please refer to the v1alpha2 design doc.
- For details of all-in-one operator design, please refer to the All-in-one Kubeflow Training Operator
- For details on its observability, please refer to the monitoring design doc.
- Version >= 1.23 of Kubernetes cluster and
kubectl
kubectl apply -k "github.com/kubeflow/training-operator/manifests/overlays/standalone"kubectl apply -k "github.com/kubeflow/training-operator/manifests/overlays/standalone?ref=v1.5.0"For users who prefer to use original TensorFlow controllers, please checkout v1.2-branch, patches for bug fixes will still be accepted to this branch.
kubectl apply -k "github.com/kubeflow/training-operator/manifests/overlays/standalone?ref=v1.2.0"Training Operator provides Python SDK for the custom resources. More docs are available in sdk/python folder.
Use pip install command to install the latest release of the SDK:
pip install kubeflow-training

This project was originally started as a distributed training operator for TensorFlow and later we merged efforts from other Kubeflow training operators to provide a unified and simplified experience for both users and developers. We are very grateful to all who filed issues or helped resolve them, asked and answered questions, and were part of inspiring discussions. We'd also like to thank everyone who's contributed to and maintained the original operators.
