Introduction

Charmed Kubeflow is an open-source, end-to-end, production-ready MLOps platform on top of cloud native technologies.

NVIDIA NeMo is an end-to-end, cloud-native framework to build, customize, and deploy generative AI models anywhere. It includes training and inferencing frameworks, guardrailing toolkits, data curation tools, and pretrained models, offering enterprises an easy, cost-effective, and fast way to adopt generative AI.

NVIDIA Triton™ Inference Server is open-source software that standardizes AI model deployment and execution across every workload.

Outline

During this workshop, you will learn how to use Nvidia NeMo and Nvidia Triton with Charmed Kubeflow. You will run an end-to-end example. A recording of the workshop will be later available.

At the end of this you will learn how to use Nvidia’s NeMo pre-trained Megatron models, adjust them to your needs using P-tuning methods and then set-up a production grade deployment using Charmed Kubeflow and Kubernetes powered by NVidia GPUs.

Minimum requirements:

64GB of RAM
NVidia GPU with 8GB or VRAM
Ubuntu 20.04 or higher

$ conda install torch torchaudio numpy scipy pandas scikit-learn matplotlib jupyterlab

$ conda install -c "nvidia/label/cuda-12.1.1" cuda-toolkit

$ CMAKE_ARGS="-DLLAMA_CUBLAS=on" FORCE_CMAKE=1 pip install llama-cpp-python --no-cache-dir --force

Open Jupyter

 jupyter lab

Scale easily with Kubeflow on Kubernetes

Deploy Charmed Kubeflow

Install Kubeflow and follow this guide.

Once installed, you need to create a Notebook using nvcr.io/nvidia/nemo:23.06

Hint: If you are on Charmed Kubeflow version 1.7 or lower you also need to apply a following poddefaults in your namespace, from 1.8 forward it’s not needed anymore

 kubectl edit poddefaults -n <YOUR NAMESPACE>

And fill it in with:

apiVersion: kubeflow.org/v1alpha1
kind: PodDefault
metadata:
  name: ngc
spec:
  args:
  - lab
  - --notebook-dir='/workspace'
  - --ip=0.0.0.0
  - --no-browser
  - --allow-root
  - --port=8888
  - --ServerApp.token=''
  - --ServerApp.password=''
  - --NotebookApp.token=''
  - --NotebookApp.password=''
  - --ServerApp.allow_origin='*'
  - --ServerApp.authenticate_prometheus=False
  - --ServerApp.base_url="$(NB_PREFIX)"
  - --NotebookApp.base_url="$(NB_PREFIX)"
  command:
  - jupyter
  desc: Enable NGC support
  selector:
    matchLabels:
      ngc: "true"

Use Kubeflow Notebooks

Open the newly created Kubeflow Notebook. Clone the Notebook and continue with the instructions described there.

If you don’t have a powerful enough machine and still prefer working from your own IDE you can follow this tutorial: Remote VS Code on public cloud

Use Nvidia Triton with Charmed Kubeflow

Setup

Before we proceed, we need to make a few changes to our K8s cluster in order to accommodate for Triton Inference Server:

Skip tag resolution for nvcr.io which requires auth to resolve triton inference server image digest:

kubectl patch cm config-deployment --patch '{"data":{"registriesSkippingTagResolving":"nvcr.io"}}' -n knative-serving

Increase progress deadline since pulling a Triton image can take a while:

kubectl patch cm config-deployment --patch '{"data":{"progressDeadline": "600s"}}' -n knative-serving

Create Triton InferenceService

To run Triton with KServe, we need to create an InferenceService capable of serving multiple models on GPU. We will request a single GPU, but can later expand this to multiple.

Create multi_model_triton.yaml with the following content:

apiVersion: "serving.kserve.io/v1beta1"
kind: "InferenceService"
metadata:
  name: "triton-mms"
spec:
  predictor:
    triton:
      args:
      - --log-verbose=1
      resources:
        limits:
          cpu: "8"
          memory: 16Gi
          nvidia.com/gpu: 1
        requests:
          cpu: "8"
          memory: 16Gi
          nvidia.com/gpu: 1

Apply the InferenceService:

kubectl apply -f multi_model_triton.yaml

Check the InferenceService status:

kubectl get isvc triton-mms

NAME URL READY PREV LATEST PREVROLLEDOUTREVISION LATESTREADYREVISION AGE
