The following sequence of steps is required to run checkpointless training recipes on HyperPod.

## Prerequisites
<a name="sagemaker-eks-checkpointless-recipes-finetune-prereqs"></a>

Before you start setting up your environment, make sure you have:
+ [ Enabled Amazon EKS support in Amazon SageMaker HyperPod](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-hyperpod-eks-prerequisites.html)
+ [ Set up HyperPod training operator (v1.2\$1)](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-eks-operator.html)
+ A shared storage location. It can be an Amazon FSx file system or NFS system that's accessible from the cluster nodes.
+ Data in one of the following formats:
  + JSON
  + JSONGZ (Compressed JSON)
  + ARROW
+ Pick a supported checkpointless training recipe for Llama 70B or GPT-OSS 120B from the [source](https://github.com/aws/sagemaker-hyperpod-recipes/tree/main/recipes_collection).
+ [ Download the hugging face model weights](https://huggingface.co/docs/hub/models-downloading) and covert to [ Nemo supported format](https://docs.nvidia.com/nemo-framework/user-guide/latest/nemo-2.0/features/hf-integration.html#importing-from-hugging-face).
+ Setup your environment

## Kubernetes environment setup
<a name="sagemaker-eks-checkpointless-finetune-recipes-kubernetes"></a>

To set up your Kubernetes environment, do the following:

1. Set up the virtual environment. Make sure your version of Python is greater than or equal to 3.10 and lower than 3.14.

   ```
   python3 -m venv ${PWD}/venv
   source venv/bin/activate
   ```

1. [ Set up kubectl and eksctl](https://docs.aws.amazon.com/eks/latest/userguide/install-kubectl.html)

1. [ Install Helm](https://helm.sh/docs/intro/install/)

1. Connect to your Kubernetes cluster

   ```
   aws eks update-kubeconfig --region "${CLUSTER_REGION}" --name "${CLUSTER_NAME}"
   ```

1. Install dependencies using one of the following methods:

   1. Method 1: SageMaker HyperPod recipes method:

      ```
      # install SageMaker HyperPod Recipes.
      git clone --recursive git@github.com:aws/sagemaker-hyperpod-recipes.git
      cd sagemaker-hyperpod-recipes
      pip3 install -r requirements.txt
      ```

   1. Method 2: kubectl with pre-defined job yaml method

      ```
      # install SageMaker HyperPod checkpointless training.
      git clone git@github.com:aws/sagemaker-hyperpod-checkpointless-training.git
      cd sagemaker-hyperpod-checkpointless-training
      ```

You can now launch the checkpointless training recipe using either the NeMo-style launcher or using kubectl.

## Launch training jobs with the recipes launcher
<a name="sagemaker-eks-checkpointless-recipes-finetune-launcher"></a>

You can use the Amazon SageMaker HyperPod recipes to submit your training job. Using the recipes involves updating k8s.yaml, config.yaml and running the launch script.

1. Update `launcher_scripts/gpt_oss/run_checkpointless_gpt_oss_120b_full_fine_tuning.sh`

   your\$1container: A Deep Learning container. To find the most recent release of the checkpointless training container, see [ checkpointless training release notes](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-eks-checkpointless-release-notes.html).

   ```

   TRAIN_DIR="${TRAIN_DIR}"
   VAL_DIR="${VAL_DIR}"
   EXP_DIR="${EXP_DIR}"
   LOG_DIR="${LOG_DIR}"
   CONTAINER_MOUNT="/data"

       recipes.dataset.dataset_path="${TRAIN_DIR}" \

       recipes.log_dir="${LOG_DIR}" \
       recipes.resume.restore_config.path="${MODEL_NAME_OR_PATH}" \
       base_results_dir="${SAGEMAKER_TRAINING_LAUNCHER_DIR}/results" \
       git.use_default=false \

       cluster_type=k8s \

       +cluster.hostNetwork=true \
       +cluster.persistent_volume_claims.0.claimName=fsx-claim \
       +cluster.persistent_volume_claims.0.mountPath="${CONTAINER_MOUNT}" \
       +recipes.dataset.val_dataset_path="${VAL_DIR}" \
       ++recipes.callbacks.3.test_fault_config.fault_prob_between_lock=1 \
   ```

1. Launch the training job

   ```
   bash launcher_scripts/gpt_oss/run_checkpointless_gpt_oss_120b_full_fine_tuning.sh
   ```

After you've submitted the training job, you can use the following command to verify if you submitted it successfully.

```
kubectl get pods

NAME                             READY   STATUS             RESTARTS        AGE
gpt-oss-120b-worker-0             0/1    running               0            36s
```

If the STATUS is at PENDING or ContainerCreating, run the following command to get more details

```
kubectl describe pod <name of pod>
```

After the job STATUS changes to Running, you can examine the log by using the following command.

```
kubectl logs <name of pod>
```

The `STATUS` will turn to `COMPLETED` when you run `kubectl get pods`.

## Launch the training job with kubectl with pre-defined yaml
<a name="sagemaker-eks-checkpointless-recipes-finetune-kubectl"></a>

Another option is to launch the training through kubectl with a pre-defined job yaml.

1. update the examples/gpt\$1oss/launch/full\$1finetune\$1gpt\$1oss\$1120b\$1checkpointless\$1p5.yaml
   + image: A Deep Learning container. To find the most recent release of the checkpointless training container, see [checkpointless training release notes](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-eks-checkpointless-release-notes.html).
   + resume.restore\$1config.path=<path\$1to\$1pretrained\$1weights>: The path to downloaded pretrained model weigths in Nemo format in [ Prerequisites](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-eks-checkpointless-recipes-finetune.html#sagemaker-eks-checkpointless-recipes-finetune-prereqs) step.
   + dataset.dataset\$1path=<path\$1to\$1dataset>: The path to the dataset that stored in the shared storage

1. Submit the job using kubectl with full\$1finetune\$1gpt\$1oss\$1120b\$1checkpointless\$1p5.yaml

   ```
   kubectl apply -f examples/gpt_oss/launch/full_finetune_gpt_oss_120b_checkpointless_p5.yaml
   ```

After you've submitted the training job, you can use the following command to verify if you submitted it successfully.

```
kubectl get pods

NAME                             READY   STATUS             RESTARTS        AGE
gpt-oss-120b-worker-0             0/1    running               0            36s
```

If the STATUS is at PENDING or ContainerCreating, run the following command to get more details

```
kubectl describe pod <name of pod>
```

After the job STATUS changes to Running, you can examine the log by using the following command.

```
kubectl logs <name of pod>
```

The STATUS will turn to Completed when you run kubectl get pods
