Quickstart

Preprequisites

The quickstart assumes user have access to Vertex AI Pipelines service.

Install the toy project with Vertex AI Pipelines support

It is a good practice to start by creating a new virtualenv before installing new packages. Therefore, use virtalenv command to create new env and activate it:

$ virtualenv venv-demo
created virtual environment CPython3.8.12.final.0-64 in 764ms
  creator CPython3Posix(dest=/home/getindata/kedro/venv-demo, clear=False, no_vcs_ignore=False, global=False)
  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy)
    added seed packages: pip==22.0.4, setuptools==60.9.3, wheel==0.37.1
  activators BashActivator,CShellActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivator
$ source venv-demo/bin/activate

Then, kedro must be present to enable cloning the starter project, along with the latest version of kedro-kubeflow plugin and kedro-docker (required to build docker images with the Kedro pipeline nodes):

$ pip install 'kedro>=0.18.1,<0.19.0' kedro-vertexai kedro-docker

With the dependencies in place, let’s create a new project:

$ kedro new --starter=spaceflights

Project Name:
=============
Please enter a human readable name for your new project.
Spaces and punctuation are allowed.
 [New Kedro Project]: Vertex AI Plugin Demo

Repository Name:
================
Please enter a directory name for your new project repository.
Alphanumeric characters, hyphens and underscores are allowed.
Lowercase is recommended.
 [vertex-ai-plugin-demo]:

Python Package Name:
====================
Please enter a valid Python package name for your project package.
Alphanumeric characters and underscores are allowed.
Lowercase is recommended. Package name must start with a letter
or underscore.
 [vertex_ai_plugin_demo]:

Change directory to the project generated in /Users/getindata/vertex-ai-plugin-demo

A best-practice setup includes initialising git and creating a virtual environment before running ``kedro install`` to install project-specific dependencies. Refer to the Kedro documentation: https://kedro.readthedocs.io/

Finally, go the demo project directory and ensure that kedro-vertexai plugin is activated:

$ cd vertexai-plugin-demo/
$ pip install -r src/requirements.txt
(...)
Requirements installed!

Build the docker image to be used in Vertex AI Pipelines runs

First, initialize the project with kedro-docker configuration by running:

$ kedro docker init

This command creates a several files, including .dockerignore. This file ensures that transient files are not included in the docker image and it requires small adjustment. Open it in your favourite text editor and extend the section # except the following by adding there:

!data/01_raw

Ensure right requirements.txt

You need to make sure that before you build the docker image and submit the job to Vertex AI Pipelines, all of your project’s Python package requirements are properly saved in requirements.txt, that includes this plugin. Ensure that the src/requirements.txt contains this line

kedro-vertexai

Adjusting Data Catalog to be compatible with Vertex AI

This change enforces raw input data existence in the image. While running locally, every intermediate dataset is stored as a MemoryDataSet. When running in VertexAI Pipelines, there is no shared-memory, Kedro-VertexAI plugin automatically handles intermediate dataset serialization - every intermediate dataset will be stored (as a compressed cloudpickle file) in GCS bucket specified in the vertexai.yml config under run_config.root key. Adjusted catalog.yml should look like this (note: remove the rest of the entries which comes with the spaceflights starter - you need only companies,reviews,shuttles.)

companies:
  type: pandas.CSVDataSet
  filepath: data/01_raw/companies.csv
  layer: raw

reviews:
  type: pandas.CSVDataSet
  filepath: data/01_raw/reviews.csv
  layer: raw

shuttles:
  type: pandas.ExcelDataSet
  filepath: data/01_raw/shuttles.xlsx
  layer: raw

All intermediate and output data will be stored in the location with the following pattern:

gs://<run_config.root from vertexai.yml>/kedro-vertexai-temp/<vertex ai job name>/*.bin

Of course if you want to use intermediate/output data and store it a location of your choice, add it to the catalog. Be aware that you cannot use local paths - use gs:// paths instead.

Disable telemetry or ensure consent

Latest version of Kedro starters come with the kedro-telemetry installed, which by default prompts the user to allow or deny the data collection. Before submitting the job to Vertex AI Pipelines you have two options:

• allow the telemetry by setting consent: true in the .telemetry file in the project root directory

• disable telemetry by removing kedro-telemetry from the src/requirements.txt.

If you leave the .telemetry file with default consent: false, the pipeline will crash in runtime in Vertex AI, because kedro-telemetry will spawn an interactive prompt and ask for the permission to collect the data.

The usage of ${run_id} is described in section Dynamic configuration support.

Build the image

Execute:

kedro docker build --build-arg BASE_IMAGE=python:3.8-buster

When execution finishes, your docker image is ready. If you don’t use local cluster, you should push the image to the remote repository:

docker tag vertex-ai-plugin-demo:latest remote.repo.url.com/vertex-ai-plugin-demo:latest
docker push remote.repo.url.com/vertex-ai-plugin-demo:latest

Run the pipeline on Vertex AI

First, run init script to create the sample configuration. There are 2 parameters:

• PROJECT_ID which is ID of your Google Cloud Platform project - can be obtained from GCP Console or from command line (gcloud config get-value project)

• REGION - Google Cloud Platform region in which the Vertex AI pipelines should be executed (e.g. europe-west1).

kedro vertexai init <GCP PROJECT ID> <GCP REGION>
(...)
Configuration generated in /Users/getindata/vertex-ai-plugin-demo/conf/base/vertexai.yaml

Then adjust the conf/base/vertexai.yaml, especially:

• image: key should point to the full image name (like remote.repo.url.com/vertex-ai-plugin-demo:latest if you pushed the image at this name).

• root: key should point to the GCS bucket that will be used internally by Vertex AI and the plugin itself, e.g. your_bucket_name/subfolder-for-vertexai

Finally, everything is set to run the pipeline on Vertex AI Pipelines. Execute run-once command:

$ kedro vertexai run-once
2022-03-18 13:44:27,667 - kedro_vertexai.client - INFO - Generated pipeline definition was saved to /var/folders/0b/mdxthmvd74x90fp84zl4mb5h0000gn/T/kedro-vertexai2jyrt89b.json
See the Pipeline job here: https://console.cloud.google.com/vertex-ai/locations/europe-west1/pipelines/runs/vertex-ai-plugin-demo-20220318124425?project=gid-ml-ops-sandbox

As you can see, the pipeline was compiled and started in Vertex AI Pipelines. When you visit the link shown in logs you can observe the running pipeline:
