Ingest Live Data into your House Price Predictor with SAP AI Core

Create a new directory named hello-aicore-data. The code is different from previous tutorial as it reads the data from folder (volumes, virtual storage spaces). The content of these volumes is dynamically loaded during execution of workflows.

Create a file named main.py, and paste the following snippet there:

import os
#
# Variables
DATA_PATH = '/app/data/train.csv'
DT_MAX_DEPTH= int(os.getenv('DT_MAX_DEPTH'))
MODEL_PATH = '/app/model/model.pkl'
#
# Load Datasets
import pandas as pd
df = pd.read_csv(DATA_PATH)
X = df.drop('target', axis=1)
y = df['target']
#
# Partition into Train and test dataset
from sklearn.model_selection import train_test_split
train_x, test_x, train_y, test_y = train_test_split(X, y, test_size=0.3)
#
# Init model
from sklearn.tree import DecisionTreeRegressor
clf = DecisionTreeRegressor(max_depth=DT_MAX_DEPTH)
#
# Train model
clf.fit(train_x, train_y)
#
# Test model
test_r2_score = clf.score(test_x, test_y)
# Output will be available in logs of SAP AI Core.
# Not the ideal way of storing /reporting metrics in SAP AI Core, but that is not the focus this tutorial
print(f"Test Data Score {test_r2_score}")
#
# Save model
import pickle
pickle.dump(clf, open(MODEL_PATH, 'wb'))

Your code reads the data file train.csv from the location /app/data, which will be prepared in a later step. It also reads the variable (hyper-parameter) DT_MAX_DEPTH from the environment variables later. When generated, your model will be stored in the location /app/model/ . You will also learn how to transport this code from SAP AI Core to your own cloud storage.

Recommendation: Although the dataset file train.csv is not present, it will be dynamically copied during execution to the volume mentioned in (/app/data). Its recommended to pass the filename (train.csv) through the environment variable to your code so that if your dataset filename changes, you can dynamically set the dataset file.

Create file requirements.txt as shown below. Here, if you don’t specify a particular version, as shown for pandas, then the latest version of the package will be fetched automatically.

scikit-learn
pandas

Create a file called Dockerfile with following contents.

This filename cannot be amended, and does not have a .filetype

# Specify which base layers (default dependencies) to use
# You may find more base layers at https://hub.docker.com/
FROM python:3.7
#
# Creates directory within your Docker image
RUN mkdir -p /app/src/
# Don't place anything in below folders yet, just create them
RUN mkdir -p /app/data/
RUN mkdir -p /app/model/
#
# Copies file from your Local system TO path in Docker image
COPY main.py /app/src/
COPY requirements.txt /app/src/  
#
# Installs dependencies within you Docker image
RUN pip3 install -r /app/src/requirements.txt
#
# Enable permission to execute anything inside the folder app
RUN chgrp -R 65534 /app && \
    chmod -R 777 /app

IMPORTANT Your Dockerfile creates empty folders to store your datasets and models (/app/data and /app/model/ in the example above). Contents from cloud storage will be copied to and from these folders later. Any contents in these folders will be overwritten by the Docker image build.

Build and upload your Docker image to Docker repository, using the following code in the terminal.

docker build -t docker.io/<YOUR_DOCKER_USERNAME>/house-price:03 .
docker push docker.io/<YOUR_DOCKER_USERNAME>/house-price:03

Create a pipeline (YAML file) named house-price-train.yaml in your GitHub repository. Use the existing GitHub path which is already synced by your application of SAP AI Core.

    container:
      image: docker.io/<YOUR_DOCKER_USERNAME>/house-price:03 # Your docker image name
      command: ["/bin/sh", "-c"]
      env:
        - name: DT_MAX_DEPTH # name of the environment variable inside Docker container
          value: "3" # will make it as variable later
      args:
        - "python /app/src/main.py"

This change to your workflow creates a placeholder through which you can specify a data path (volume) to the container (Docker image in execution).

1. A placeholder named housedataset is created.
2. You specify the kind of artifact that the placeholder can accept. Artifact is covered in details later in this tutorial.
3. You use a placeholder to specify the path that you created in your Dockerfile, which is where you will copy files to your Docker image.

Why do we need to create placeholders?

SAP AI Core only uses your workflows as an interface, so is unaware of the volume/ attachments specified in your Docker image. Your data path is specified in your Dockerfile and has a placeholder in your workflow and data is then expected by the Docker image.

In your workflow, you have used the variable DT_MAX_DEPTH to incorporate a static value from the corresponding environment variable. Let’s make this a variable in the workflow.

Replace the contents of the above AI workflow with this snippet.

apiVersion: argoproj.io/v1alpha1

  templates:
  - name: mypipeline
    steps:
    - - name: mypredictor
        template: mycodeblock1
  - name: mycodeblock1
    # Add your resource plan here. The annotation should follow metadata > labels > ai.sap.com/resourcePlan: <plan>
    inputs:
      artifacts:  # placeholder for cloud storage attachements
        - name: housedataset # a name for the placeholder
          path: /app/data/ # where to copy in the Dataset in the Docker image
    container:
      image: docker.io/<YOUR_DOCKER_USERNAME>/house-price:03 # Your docker image name
      command: ["/bin/sh", "-c"]
      env:
        - name: DT_MAX_DEPTH # name of the environment variable inside Docker container
          value: "{{workflow.parameters.DT_MAX_DEPTH}}" # value to set from local (to workflow) variable DT_MAX_DEPTH
      args:
        - "python /app/src/main.py"

The following shows the new important lines in the workflows.

####Understanding these changes

1. A placeholder named DT_MAX_DEPTH is created locally in the workflow. It accepts number content of input type: string. The input is then type cast to an integer elsewhere in your code, so it must be a string containing integers. For example: "4" is acceptable because it is a string containing content that can can be type cast to and integer.
2. You create an input env (Environment) variable to your Docker image, named DT_MAX_DEPTH. The value of this variable is fed in from workflow.parameters.DT_MAX_DEPTH,the local name from previous point.

Commit the changes in the GitHub.

Add the following snippet in your workflow to specify resource plan. The resource plan helps specify computing resource required to run your Docker image. The computing resources includes GPU, RAM and Processor. If not mentioned the resource plan defaults to starter which is the entry level resource plan.

spec:
    ...
    templates:
    ...
    - name: mycodeblock1
      metadata:
        labels:
            ai.sap.com/resourcePlan: starter
    ...

INFORMATION: You can always verify computing resource allocated using the following command echo $(lscpu) within your Docker image. The command is the the shell script command of Linux to print system configuration.

Observe the value of the name variable in both inputArtifacts and parameters. These represent the placeholder names which were specified earlier in the process. You are required use these names later when creating your configuration.

Why use cloud storage?

SAP AI Core only provides your ephemeral (short-lived) storage, while training or inferencing a model. Amazon Web Services (AWS) S3 Object store is the cloud storage used by SAP AI Core for storing datasets and models. Here, they can be stored over a longer time period, and can be transferred to and from SAP AI Core during training or online inferencing.

You need to create AWS S3 object store, using one of the following links:

• If you are a BTP user, create your storage through the SAP Business Technology Platform. While BTP offers alternative storage solutions, this tutorial uses AWS S3.
• If you are not a BTP user, go directly through AWS site

Download and Install the AWS Command Line Interface (CLI).

To configure settings for your CWS CLI, open your terminal and run:

aws configure

Enter your AWS credentials. Note that the appearance of the screen will not change as you type. You can leave the Default output format entry as blank. Press enter to submit your credentials.

Your credentials are stored in your system and used by the AWS CLI to interact with AWS. Fore more information, see Configuring the AWS CLI

Download the train.csv dataset. You need to right click, and save the page as train.csv.

INFORMATION The data used is from Scikit Learn. The source of the data is here.

To upload the datasets to your AWS S3 Storage, paste and edit the following command in the terminal:

aws s3 cp train.csv s3://<YOUR_BUCKET_NAME>/example-dataset/house-price-toy/data/jan/train.csv

This command uploaded the data to a folder called jan. Upload it one more time in another folder called feb, by changing your command as shown:

aws s3 cp train.csv s3://<YOUR_BUCKET_NAME>/example-dataset/house-price-toy/data/feb/train.csv

You now know how to upload and use multiple datasets with SAP AI Core.

List your files in your AWS S3 bucket by editing the following command:

aws s3 ls s3://<YOUR_BUCKET_NAME/example-dataset/house-price-toy/data/

CAUTION: Ensure your file names and format match what you have specified in your code. For example, if you specify ´train.csv´ in your code, the system expects a file called train, which is of type: comma separated value.

An object store secret is required to store credentials to access your AWS S3 buckets, and limit access to a particular directory.

{
    "name": "mys3",
    "data": {
        "AWS_ACCESS_KEY_ID": "<YOUR_AWS_ID>",
        "AWS_SECRET_ACCESS_KEY": "<YOUR_AWS_KEY>"
    },
    "type": "S3",
    "bucket": "<YOUR_BUCKET_NAME>",
    "endpoint": "s3-eu-central-1.amazonaws.com",
    "region": "eu-central-1",
    "pathPrefix": "example-dataset/house-price-toy"
}

{
    "message": "secret has been created"
}

# Create object Store secret
response = ai_core_client.object_store_secrets.create(
    name = "mys3", # identifier for this secret within your SAP AI Core
    path_prefix = "example-dataset/house-price-toy", # path that we want to limit restrict this secret access to
    type = "S3",
    data = { # Dictionary of credentials of AWS
        "AWS_ACCESS_KEY_ID": "<YOUR_AWS_ID>",
        "AWS_SECRET_ACCESS_KEY": "<YOUR_AWS_KEY>"
    },
    bucket = "<YOUR_BUCKET_NAME>", # Edit this
    region = "eu-central-1", # Edit this
    endpoint = "s3-eu-central-1.amazonaws.com", # Edit this
    resource_group = "default" # object store secret are restricted within this resource group. you may change this when creating secret for another resource group.
)
print(response.__dict__)

• The Resource Group must be default
• The Name field is your choice of identifier for your secret within SAP AI Core.
• Entries to the other fields are found in your AWS account. Endpoint
• This is where you specify the host for your S3 service.
• Use the endpoint URL associated with your AWS S3 bucket’s region.
• Example for the EU Central region:s3-eu-central-1.amazonaws.com
• If you are using the standard AWS global endpoint, you can use:
s3.amazonaws.com

Note: This value corresponds to the host element in the credentials you receive when creating the S3 Object Store in BTP. AWS may provide multiple URLs, endpoints, and URIs, so ensure you enter the one specific to your bucket’s region or your S3 service host. has context menu

Why not put a complete path to train.csv as pathPrefix?

You might have noticed that previously you uploaded data to example-dataset/house-price-toy/data/jan/train.csv but here in object store secret the pathPrefix is you set the value example-dataset/house-price-toy. This is because the use of pathPrefix is to restrict access to particular directory of your cloud storage.

Why define a complete path instead of using the pathPrefix? Using a root path only would mean that all files and subdirectories in the path would be copied from your AWS S3 to SAP AI Core. This might not be useful where you have multiple datasets only one of them is in use. Extending the pathPrefix to a complete path allows the user to specify specific artifacts.

With your object store secret created, you can now reference any sub-folders to pathPrefix containing artifacts such as datasets or models.

INFORMATION You may create any number of object store secrets each with unique name. They can point to the same or different object stores.

You have learnt to add data artifacts, allowing you to ingest more data over time.

Important points to notice

1. Notice the url used in above snippet is ai://mys3/data/jan, here mys3 is the object store secret name that you created previously. Hence the path translates as ai://<PATH_PREFIX_OF_mys3>/data/jan which is the directory that your dataset file is located in.
2. The url points to a directory, not a file, which gives you advantage that you can store multiple files in an AWS S3 directory and register the directory containing all files as a single artifact.
3. All the files present in the path referenced by artifact will be copied from your S3 storage to your SAP AI Core instance during training or inferencing. This includes subfolders, apart from where Kind = MODEL.

### List Artifacts

INFORMATION Artifacts appear in the default resource group and the Datasets menu, because you had registered artifacts with resource_group = default and Kind = Dataset in Step 9.

Copy the artifact ID of the January dataset. You will use this value in the placeholders of your workflows to create your execution. The ID of artifacts allows SAP AI Core to ingest data into workflows.

You added a new outputs section, where you specified files and their directories, which are created during the execution, and will be uploaded to AWS S3 and automatically registered as artifacts in SAP AI Core. You also added a line in the annotations section, which specified the kind of artifact that would be generated. In this case, a model.

All of the contents within your /app/model/ directory, as defined in your Docker image, will be uploaded to AWS S3. This implies you may generate multiple files of any format after training, for example class_labels.npy, model.h5, classifier.pkl or tokens.json.

It is compulsory to create a object store secret named default within your resource group, for your executable to generate models and store them in AWS S3. After execution the model will be saved to PATH_PREFIX_of_default/<execution_id>/housepricemodel in your AWS S3. The housepricemodel is mentioned in the workflow in the previous step.

{
    "name": "default",
    "data": {
        "AWS_ACCESS_KEY_ID": "<YOUR_AWS_ID>",
        "AWS_SECRET_ACCESS_KEY": "<YOUR_AWS_KEY>"
    },
    "type": "S3",
    "bucket": "<YOUR_BUCKET_NAME>",
    "endpoint": "s3-eu-central-1.amazonaws.com",
    "region": "eu-central-1",
    "pathPrefix": "example-dataset/house-price-toy/model"
}

# Create object Store secret for placing models to S3
response = ai_core_client.object_store_secrets.create(
    name = "default", # name must be `default`
    path_prefix = "example-dataset/house-price-toy/model", # ensure path prefix is targeted to your models subdirectory
    type = "S3",
    data = { # Dictionary of credentials of AWS
        "AWS_ACCESS_KEY_ID": "<YOUR_AWS_ID>",
        "AWS_SECRET_ACCESS_KEY": "<YOUR_AWS_KEY>"
    },
    bucket = "<YOUR_BUCKET_NAME>", # bucket name,
    region = "eu-central-1", # Edit this
    endpoint = "s3-eu-central-1.amazonaws.com", # Edit this
    resource_group = "default"
)
print(response.__dict__)

This time, train the model with the feb dataset and with a different hyper-parameter value.

{
    "name": "House Price Feburary 1",
    "scenarioId": "learning-datalines",
    "executableId": "data-pipeline",
    "inputArtifactBindings": [
        {
            "key": "housedataset",
            "artifactId": "<YOUR_FEB_ARTIFACT_ID>"
        }
    ],
    "parameterBindings": [
        {
            "key": "DT_MAX_DEPTH",
            "value": "5"
        }
    ]
}

from ai_api_client_sdk.models.parameter_binding import ParameterBinding
from ai_api_client_sdk.models.input_artifact_binding import InputArtifactBinding

response = ai_core_client.configuration.create(
    name = "House Price Feburary 1",
    scenario_id = "learning-datalines",
    executable_id = "data-pipeline",
    input_artifact_bindings = [
        InputArtifactBinding(key = "housedataset", artifact_id = "<YOUR_FEB_ARTIFACT_ID>") # placeholder as name
    ],
    parameter_bindings = [
        ParameterBinding(key = "DT_MAX_DEPTH", value = "5") # placeholder name as key
    ],
    resource_group = "default"
)
print(response.__dict__)

Use your new configuration to create an execution.

# execute this multiple times in interval of 30 seconds
response = ai_core_client.execution.get(
    execution_id = '<YOUR_EXECUTION_ID>',
    resource_group = 'default'
)

for key, value in response.__dict__.items():
    if "output" in key:
        print(f"{key} : ")
        for artifact in value:
            print(f" {artifact.__dict__}")
    else:
        print(f"{key} : {value}")

When your execution shows status COMPLETED, you will see that a new model artifact called housepricemodel has been generated. Note that the outputArtifacts are automatically registered and copied to AWS S3. Note that your artifact is of the kind model and that its ID is its only unique identifier - not its name.

Generating and associating metrics (model quality) will covered in a separate tutorial.

Go to executions and click on Schedule.

Choose your scenario and click on Next.

Choose your executable and click on Next.

Choose your configuration and click on Next.

Give a name for the schedule and set the time.

Click Create.

Now go to Schedules to see your schedules.

List your new files by pasting and editing the following snippet in your terminal.

aws s3 ls s3://<YOUR_BUCKET_NAME>/example-dataset/house-price-toy/model/<YOUR_EXECUTION_ID>/housepricemodel

You are listing the files in the path example-dataset/house-price-toy/model/ because this is the value you set earlier for the pathPrefix variable, for your object store secret named default.
