This workshop has been deprecated and archived. The new Amazon EKS Workshop is now available at www.eksworkshop.com.
Jupyter notebooks are a great way to author your model creation. You can write the algorithms, train the model and if you need a way to publish the inference endpoint directly from this interface, you can use Kubeflow fairing to do so
For this chapter, we will make use of both S3 and ECR services. We’ll use S3 to store and access pipeline data. We’ll use ECR as our container registry for the training image. We need to add IAM policies to Worker nodes so that we can access both S3 and ECR. Run below commands in Cloud9 and assign desired permission
aws iam attach-role-policy --role-name $ROLE_NAME --policy-arn arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryFullAccess aws iam attach-role-policy --role-name $ROLE_NAME --policy-arn arn:aws:iam::aws:policy/AmazonS3FullAccess
Create new notebook server by following [Jupyter notebook chapter] (/advanced/420_kubeflow/jupyter). Before you jump to the link, take a note of custom image (527798164940.dkr.ecr.us-west-2.amazonaws.com/tensorflow-1.15.2-notebook-cpu:1.0.0) that you will use for eks-kubeflow-workshop notebook server. Below screenshot depicts how to use custom image
We will clone Github repo from a Jupyter notebook so that we can readily use authored notebooks in this chapter.
Create new Python 3 Notebook if one doesn’t exist. Run the command below to clone the repo
!git clone https://github.com/aws-samples/eks-kubeflow-workshop.git
Click Run. This will clone the repo into your notebook server
Close the notebook tab, go back to the notebook server, select the notebook that we just used and click Shutdown.
Browse the “eks-kubeflow-workshop” repository and go to fairing introduction notebook (eks-kubeflow-workshop/notebooks/02_Fairing/02_01_fairing_introduction.ipynb). You can either click on the notebook to open or select and click View
Starting from here, its important to read notebook instructions carefully. The info provided in the workshop is lightweight and you can use it to ensure desired result. You can complete the exercise by staying in the notebook
Review the content and click first cell and click Run. This will let you install Fairing from Github repository
Wait till it finishes, go to next cell and click Run. Here is expected result
Now that we have fairing installed, we will train a model authored in Python. The model will create a linear regression model that allows us to learn a function or relationship from a given set of continuous data. For example, we are given some data points of x and corresponding y and we need to learn the relationship between them that is called a hypothesis.
In case of linear regression, the hypothesis is a straight line i.e, h(x) = x * weight + b.
Run cell 3. Once it completes, run cell 4. This will create a model locally on our notebook
Now, lets use fairing and push the image into ECR which can be used for remote training
Before you run authenticate with ECR, change the region if needed. Run this cell and login so that you can perform ECR operations
Run the next cell and create an ECR repository (fairing-job) in the same region. You should see similar output
Let’s run next cell. Fairing pushes the image to ECR and then deploys the model remotely
Now that we have demonstrated how to use Fairing to train locally and remotely, let’s train and deploy XGBoost model and review an end to end implementation
For this exercise, we will use another notebook called 02_06_fairing_e2e.ipynb
Go back to your notebook server and shutdown 02_01_fairing_introduction.ipynb notebook. Open the 02_06_fairing_e2e.ipynb
Let’s install python dependencies by running first 2 cells, and then run next 2 cells under “Develop your model”
Run the next cell to train the XGBoost model locally. Here is the expected result
Now lets create an S3 bucket to store pipeline data. Remember to change HASH to a random value before running next cell
Running next two steps will setup Fairing backend. Remember to change S3 bucket name before running next cell
Now lets submit the Trainjob. Here is the expected result
Running next step will deploy prediction endpoint using Fairing. You will endpoint details at the bottom.
Let’s call this prediction endpoint. Remember to replace with your endpoint before running next two cells
This demonstrates how to build XGBoost model using Fairing and deploy it locally and to remote endpoint.
Run the next steps to cleanup resources from this exercise
