The ibm-watson-machine-learning (V4) library ¶

The ibm-watson-machine-learning Python library allows you to work with IBM Watson Machine Learning services. You can train, store, and deploy your models, score them using APIs, and finally integrate them with your application development. The ibm-watson-machine-learning library can work with IBM Cloud Pak® for Data as a Service (later referred to as IBM Cloud) V2 instance plans (created after Sept 1 2020) as well as IBM Cloud Pak® for Data version 3.5 and higher. For older versions of IBM Cloud Pak® for Data, use the beta version of the library provided under link.

Note: For IBM Cloud, if you are using Watson Machine Learning Python client V3 or Watson Machine Learning Python client V4 Beta, refer to the documentation for the migration process, to be able to migrate your assets to new instance plans and access new features.

Important: Python 3.6 framework is deprecated. For IBM Cloud, it is currently in read-only mode and will be removed on Apr 8th, 2021. This means that you won’t be able to create new assets using this client. Use Python 3.7 instead. For details, see Supported Frameworks. For IBM Cloud Pak® for Data, Python 3.6 framework is supported only for python 3.6 users upgrading from 3.0.1 to 3.5 and will be removed from a future release. We recommend you migrate your assets and use a Python 3.7 framework instead. For details, see Supported Frameworks.

Important: The Watson Machine Learning Python client V3 and Watson Machine Learning Python client V4 Beta are deprecated since Sep 1st, 2020 on cloud and will be discontinued at the end of the migration period. Migrate to IBM Watson Machine Learning Client V4 GA packaged in the name of ibm-watson-machine-learning on cloud.

Installation ¶

The ibm-watson-machine-learning Python library is integrated into the Watson Studio Jupyter notebook. Also, the package is available from pypi. To install it for use with IBM Cloud services, type:

$pip install ibm-watson-machine-learning

API for IBM Cloud ¶

To use Watson Machine learning APIs, create an instance of APIClient with authentication details.

Requirements ¶

To create a Watson Machine Learning service instance, refer to the documentation.

Authentication ¶

Authentication for IBM Cloud

To use Watson Machine learning APIs, create an instance of APIClient with authentication details.

Example of creating the client using apikey:

Note: There is no need to provide instance_id. For the new(V2) instance plans, the instance_id is picked up from associated space/project. To access your assets from old(V1) instance plans, provide your old V1 instance_id in the wml_credentials and create a client object.

from ibm_watson_machine_learning import APIClient

wml_credentials = {
                   "url": "https://us-south.ml.cloud.ibm.com",
                   "apikey":"***********"
                  }

client = APIClient(wml_credentials)

Example of creating the client using token:

from ibm_watson_machine_learning import APIClient

wml_credentials = {
                   "url": "https://us-south.ml.cloud.ibm.com",
                   "token":"***********",
                  }

client = APIClient(wml_credentials)

Example of creating the client using V1 Lite instance plan:

from ibm_watson_machine_learning import APIClient

wml_credentials = {
                   "url": "https://example.ml.cloud.ibm.com",
                   "apikey":"**********",
                   "instance_id": "v1 lite instance_id"
                  }

client = APIClient(wml_credentials)

Note: Setting default space/project id is mandatory. For details, refer to client.set.default_space() API in this document.

  keras (.tgz)
  
  pmml (.xml)
  
  scikit-learn (.tar.gz)
  
  tensorflow (.tar.gz)
  
  spss (.str)
- directory containing model file(s):
  scikit-learn
  
  xgboost
  
  tensorflow
- unique id of trained model
training_data: Spark DataFrame supported for spark models. Pandas dataframe, numpy.ndarray or array supported for scikit-learn models

type: spark dataframe, pandas dataframe, numpy.ndarray or array
meta_props: meta data of the models configuration. To see available meta names use:
```

type: numpy.ndarray or list
label_column_names: Label column names of the trained Scikit-Learn/XGBoost models.

type: numpy.ndarray and list

Output

Important

returns: Metadata of the model created

return type: dict

Note

For a keras model, model content is expected to contain a .h5 file and an archived version of it.
feature_names is an optional argument containing the feature names for the training data in case of Scikit-Learn/XGBoost models. Valid types are numpy.ndarray and list. This is applicable only in the case where the training data is not of type - pandas.DataFrame.
If the training data is of type pandas.DataFrame and feature_names are provided, feature_names are ignored.
The value can be a single dictionary(being deprecated, use list even for single schema) or a list if you are using single input data schema. you can provide multiple schemas as dictionaries inside a list.

Example

>>> stored_model_details = client.repository.store_model(model, name)

In more complicated cases you should create proper metadata, similar to this one:

>>> sw_spec_id = client.software_specifications.get_id_by_name('scikit-learn_0.23-py3.7')
>>> sw_spec_id
>>> metadata = {
>>>        client.repository.ModelMetaNames.NAME: 'customer satisfaction prediction model',
>>>        client.repository.ModelMetaNames.SOFTWARE_SPEC_UID: sw_spec_id,
>>>        client.repository.ModelMetaNames.TYPE: 'scikit-learn_0.23'
>>>}

In case when you want to provide input data schema of the model, you can provide it as part of meta

>>> sw_spec_id = client.software_specifications.get_id_by_name('spss-modeler_18.1')
>>> sw_spec_id
>>> metadata = {
>>>        client.repository.ModelMetaNames.NAME: 'customer satisfaction prediction model',
>>>        client.repository.ModelMetaNames.SOFTWARE_SPEC_UID: sw_spec_id,
>>>        client.repository.ModelMetaNames.TYPE: 'spss-modeler_18.1',
>>>        client.repository.ModelMetaNames.INPUT_DATA_SCHEMA: [{'id': 'test',
>>>                                                             'type': 'list',

>>>                                                                         {'name': 'restbp', 'type': 'float'}]
>>>                                                               },

>>>                                                                'type': 'list',
>>>                                                                'fields': [{'name': 'age', 'type': 'float'},
>>>                                                                           {'name': 'sex', 'type': 'float'},
>>>                                                                           {'name': 'fbs', 'type': 'float'},
>>>                                                                           {'name': 'restbp', 'type': 'float'}]

Working with AutoAI class and optimizer ¶

The AutoAI experiment class is responsible for creating experiments and scheduling training. All experiment results are stored automatically in the user-specified Cloud Object Storage (COS). Then, the AutoAI feature can fetch the results and provide them directly to the user for further usage.

Configure optimizer with one data source ¶

For an AutoAI object initialization WML credentials (with apikey and url) and one of project_id or space_id.

from ibm_watson_machine_learning.experiment import AutoAI

experiment = AutoAI(wml_credentials,
    space_id='76g53e0-0b32-4a0e-9152-3d50324855ddb')
)

pipeline_optimizer = experiment.optimizer(
            name='test name',
            desc='test description',
            prediction_type=AutoAI.PredictionType.BINARY,
            prediction_column='y',
            scoring=AutoAI.Metrics.ACCURACY_SCORE,
            test_size=0.1,
            max_num_daub_ensembles=1,
            train_sample_rows_test_size=1.,
            daub_include_only_estimators = [
                 AutoAI.ClassificationAlgorithms.XGB,
                 AutoAI.ClassificationAlgorithms.LGBM
                 ],
            cognito_transform_names = [
                 AutoAI.Transformers.SUM,
                 AutoAI.Transformers.MAX
                 ]
        )

Configure optimizer with joined data (BETA)¶

AutoAI allows you to combine data from multiple data sources into a single data source input for the experiment.

To join data sources, define the join with an additional parameter: data_join_node_name.

main_conn = DataConnection(
    data_join_node_name="main",
    connection=S3Connection(...),
    location=S3Location(bucket=bucket_name,
                        path=data_cos_path + 'group_customer_main.csv'))

customers_transactions_conn = DataConnection(
    data_join_node_name=["customers", "transactions"],
    connection=S3Connection(...),
    location=S3Location(bucket=bucket_name,
                        path=data_cos_path + 'group_customer.xlsx'))

customers_conn = DataConnection(
    data_join_node_name="customers",
    connection=S3Connection(...),
    location=S3Location(bucket=bucket_name,
                        path=data_cos_path + 'group_customer_customers.csv'))

transactions_conn = DataConnection(
    data_join_node_name="transactions",
    connection=S3Connection(...),
    location=S3Location(bucket=bucket_name,
                        path=data_cos_path + 'group_customer_transactions.csv'))

purchases_conn = DataConnection(
    data_join_node_name="purchases",
    connection=S3Connection(...),
    location=S3Location(bucket=bucket_name,
                        path=data_cos_path + 'group_customer_purchase.csv'))

products_conn = DataConnection(
    data_join_node_name="products",
    connection=S3Connection(...),
    location=S3Location(bucket=bucket_name,
                        path=data_cos_path + 'group_customer_products.csv'))

results_connection = DataConnection(
    connection=S3Connection(...),
    location=S3Location(bucket=bucket_name,
                        path=results_cos_path))

data_connections = [main_conn,
                    customers_transactions_conn,
                    purchases_conn,
                    products_conn]

Next step is to create a join graph object (instance of the DataJoinGraph class). When you create the object, you can add additional parameters for specific files that contain data. For example, csv_separator for csv, or sheet_name for xlsx.

Using data_join_node_name, you can first define graph nodes and then graph edges.

data_join_graph = DataJoinGraph()
data_join_graph.node(name="main", csv_separator=";")
data_join_graph.node(name="customers", sheet_name="customers")
data_join_graph.node(name="transactions", sheet_name="transactions")
data_join_graph.node(name="purchases")
data_join_graph.node(name="products")
data_join_graph.edge(from_node="main", to_node="customers",
                     from_column=["group_customer_id"], to_column=["group_customer_id"])
data_join_graph.edge(from_node="main", to_node="transactions",
                     from_column=["transaction_id"], to_column=["transaction_id"])
data_join_graph.edge(from_node="main", to_node="purchases",
                     from_column=["group_id"], to_column=["group_id"])
data_join_graph.edge(from_node="transactions", to_node="products",
                     from_column=["product_id"], to_column=["product_id"])

You can now use your join graph in the optimizer configuration step.

In a multi-data source scenario, a join graph is passed as a parameter:

experiment = AutoAI(wml_credentials,
    space_id='76g53e0-0b32-4a0e-9152-3d50324855ddb')
)

pipeline_optimizer = experiment.optimizer(
    name='obm scenario',
    prediction_type=AutoAI.PredictionType.REGRESSION,
    prediction_column='next_purchase',
    scoring=AutoAI.Metrics.LOG_LOSS,
    max_number_of_estimators=1,
    daub_include_only_estimators=[experiment.RegressionAlgorithms.LGBM],
    data_join_graph=data_join_graph,
    t_shirt_size=experiment.TShirtSize.L,
    test_size=0.1
)

Configure optimizer for time series forecasting (BETA)¶

Time series forecasting is a special AutoAI prediction scenario, with specific parameters used to configure forecasting: prediction_columns, timestamp_column_name, backtest_num, lookback_window, forecast_window, backtest_gap_length

from ibm_watson_machine_learning.experiment import AutoAI

experiment = AutoAI(wml_credentials,
    space_id='76g53e0-0b32-4a0e-9152-3d50324855ddb')
)

pipeline_optimizer = experiment.optimizer(
    name='forecasting optimiser',
    desc='description',
    prediction_type=experiment.PredictionType.FORECASTING,
    prediction_columns=['value'],
    timestamp_column_name='timestamp',
    backtest_num=4,
    lookback_window=5,
    forecast_window=2,
    holdout_size=0.05,
    max_number_of_estimators=1,
    include_only_estimators=[AutoAI.ForecastingAlgorithms.ENSEMBLER],
    t_shirt_size=TShirtSize.L
)

Optimizer and deployment fitting procedures are the same as in the basic scenario.

Get configuration parameters ¶

To see current configuration parameters, call the get_params() method.

config_parameters = pipeline_optimizer.get_params()
print(config_parameters)
{
    'name': 'test name',
    'desc': 'test description',
    'prediction_type': 'classification',
    'prediction_column': 'y',
    'scoring': 'roc_auc',
    'test_size': 0.1,
    'max_num_daub_ensembles': 1
}

Fit optimizer ¶

To schedule an AutoAI experiment, call the fit() method. This will trigger a training and an optimization process on WML. The fit() method can be synchronous (background_mode=False), or asynchronous (background_mode=True). If you don’t want to wait for fit to end, invoke the async version. It immediately returns only fit/run details. If you invoke the async version, you see a progress bar with information about the learning/optimization process.

fit_details = pipeline_optimizer.fit(
        training_data_reference=[training_data_connection],
        training_results_reference=results_connection,
        background_mode=True)

# OR

fit_details = pipeline_optimizer.fit(
        training_data_reference=[training_data_connection],
        training_results_reference=results_connection,
        background_mode=False)

Get run status, get run details ¶

If you use the fit() method asynchronously, you can monitor the run/fit details and status, using the following two methods:

status = pipeline_optimizer.get_run_status()
print(status)
'running'

# OR

'completed'

run_details = pipeline_optimizer.get_run_details()
print(run_details)

Get data connections ¶

The data_connections list contains all training connections that you referenced while calling the fit() method.

data_connections = pipeline_optimizer.get_data_connections()

Summary ¶

It is possible to get a ranking of all the computed pipeline models, sorted based on a scoring metric supplied when configuring the optimizer (scoring parameter). The output type is a pandas.DataFrame with pipeline names, computation timestamps, machine learning metrics, and the number of enhancements implemented in each of the pipelines.

results = pipeline_optimizer.summary()
print(results)
               Number of enhancements  ...  training_f1
Pipeline Name                          ...
Pipeline_4                          3  ...     0.555556
Pipeline_3                          2  ...     0.554978
Pipeline_2                          1  ...     0.503175
Pipeline_1                          0  ...     0.529928

Get pipeline details ¶

To see pipeline composition steps and nodes, use the get_pipeline_details() method. If you leave pipeline_name empty, the method returns the details of the best computed pipeline.

pipeline_params = pipeline_optimizer.get_pipeline_details(pipeline_name='Pipeline_1')
print(pipeline_params)
{
    'composition_steps': [
        'TrainingDataset_full_199_16', 'Split_TrainingHoldout',
        'TrainingDataset_full_179_16', 'Preprocessor_default', 'DAUB'
        ],
    'pipeline_nodes': [
        'PreprocessingTransformer', 'LogisticRegressionEstimator'
        ]
}

Get pipeline ¶

Use the get_pipeline() method to load a specific pipeline. By default, get_pipeline() returns a lale pipeline. For information on lale pipelines, refer to (https://github.com/ibm/lale).

pipeline = pipeline_optimizer.get_pipeline(pipeline_name='Pipeline_4')
print(type(pipeline))
'lale.operators.TrainablePipeline'

You can also load a pipeline as a scikit learn (sklearn) pipeline model type.

pipeline = pipeline_optimizer.get_pipeline(pipeline_name='Pipeline_4', astype=AutoAI.PipelineTypes.SKLEARN)
print(type(pipeline))
<class 'sklearn.pipeline.Pipeline'>

Working with deployments ¶

This section describes classes that enable you to work with Watson Machine Learning deployments.

Web Service ¶

Web Service is an online type of deployment. It allows you to upload and deploy your model, to score it through an online web service. You must pass the location where the training was performed (source_space_id or source_project_id). The model can be deployed to any space or project (target_space_id or target_project_id).

Note: WebService supports only the AutoAI deployment type.

from ibm_watson_machine_learning.deployment import WebService

# note: only AutoAI deployment is possible now
service = WebService(wml_credentials,
     source_space_id='76g53e0-0b32-4a0e-9152-3d50324855ddb',
     target_space_id='1234abc1234abc1234abc1234abc1234abcd')
 )

service.create(
       experiment_run_id="...",
       model=model,
       deployment_name='My new deployment'
   )

Batch ¶

Batch manages the batch type of deployment. It allows you to upload and deploy a model and run a batch deployment job. As in Web Service, you must pass the location where the training was performed (source_space_id or source_project_id). The model can be deployed to any space or project (target_space_id or target_project_id).

The input data can be provided as a pandas.DataFrame, a data-asset, or a Cloud Object Storage (COS) file.

Note: WebService supports only the AutoAI deployment type.

Example of a batch deployment creation:

from ibm_watson_machine_learning.deployment import Batch

service_batch = Batch(wml_credentials, source_space_id='76g53e0-0b32-4a0e-9152-3d50324855ddb')
service_batch.create(
        experiment_run_id="6ce62a02-3e41-4d11-89d1-484c2deaed75",
        model="Pipeline_4",
        deployment_name='Batch deployment')

Example of a batch job creation with inline data as pandas.DataFrame type:

scoring_params = service_batch.run_job(
            payload=test_X_df,
            background_mode=False)

Example of batch job creation with a COS object:

from ibm_watson_machine_learning.helpers.connections import S3Connection, S3Location, DataConnection

payload_reference = DataConnection(
        connection=S3Connection(endpoint_url='url of the COS endpoint',
                                access_key_id='COS access key id',
                                secret_access_key='COS secret acces key'
                                ),
        location=S3Location(bucket='bucket_name',   # note: COS bucket name where deployment payload dataset is located
                            path='my_path'  # note: path within bucket where your deployment payload dataset is located
                            )
    )

results_reference = DataConnection(
        connection=S3Connection(endpoint_url='url of the COS endpoint',
                                access_key_id='COS access key id',
                                secret_access_key='COS secret acces key'
                                ),
        location=S3Location(bucket='bucket_name',   # note: COS bucket name where deployment output should be located
                            path='my_path_where_output_will_be_saved'  # note: path within bucket where your deployment output should be located
                            )
    )
payload_reference.write("local_path_to_the_batch_payload_csv_file", remote_name="batch_payload_location.csv"])

scoring_params = service_batch.run_job(
    payload=[payload_reference],
    output_data_reference=results_reference,
    background_mode=False)   # If background_mode is False, then synchronous mode is started. Otherwise job status need to be monitored.

Example of a batch job creation with a data-asset object.

from ibm_watson_machine_learning.helpers.connections import DataConnection, CloudAssetLocation, DeploymentOutputAssetLocation

payload_reference = DataConnection(location=CloudAssetLocation(asset_id=asset_id))
results_reference = DataConnection(
        location=DeploymentOutputAssetLocation(name="batch_output_file_name.csv"))

    scoring_params = service_batch.run_job(
        payload=[payload_reference],
        output_data_reference=results_reference,
        background_mode=False)

Working with DataConnection ¶

DataConnection is the base class to start working with your data storage needed for AutoAI backend. You can use it to fetch training data and store all of the results. There are several ways you can use the DataConnection object. This is a basic scenario.

To start an AutoAI experiment, first specify where your training dataset is located. Currently, AutoAI supports Cloud Object Storage (COS) and data assets on Cloud.

Cloud DataConnection Initialization ¶

To upload your experiment dataset, you must initialize DataConnection with your COS credentials.

from ibm_watson_machine_learning.autoai.helpers.connections import S3Connection, S3Location, DataConnection

# note: this DataConnection will be used as a reference where to find your training dataset
training_data_connection = DataConnection(
        connection=S3Connection(endpoint_url='url of the COS endpoint',
                                access_key_id='COS access key id',
                                secret_access_key='COS secret acces key'
                                ),
        location=S3Location(bucket='bucket_name',   # note: COS bucket name where training dataset is located
                            path='my_path'  # note: path within bucket where your training dataset is located
                            )
    )

# note: this DataConnection will be used as a reference where to save all of the AutoAI experiment results
results_connection = DataConnection(
        connection=S3Connection(endpoint_url='url of the COS endpoint',
                                access_key_id='COS access key id',
                                secret_access_key='COS secret acces key'
                                ),
        # note: bucket name and path could be different or the same as specified in the training_data_connection
        location=S3Location(bucket='bucket_name',
                            path='my_path'
                            )
    )

Upload your training dataset ¶

An AutoAI experiment should be able to access your training data. If you do not have a training dataset stored already, you can do it by invoking the write() method of the DataConnection object.

training_data_connection.write(data='local_path_to_the_dataset', remote_name='training_dataset.csv')

Download your training dataset ¶

To download a stored dataset, use the read() method of the DataConnection object.

dataset = training_data_connection.read()   # note: returns a pandas DataFrame

API for IBM Cloud Pak for Data , IBM Watson Machine Learning Server ¶

To use IBM Watson Machine learning Python client APIs in IBM Cloud Pak® for Data or IBM Watson Machine Learning Server, first create an instance of the APIClient with authentication details.

Authentication ¶

Authentication for IBM Cloud Pak® for Data(CP4D)

If you are a user of IBM Cloud Pak® for Data version 4.0, you can create an IBM Watson Machine Learning Python client by providing credentials, or using a token:

Example of creating the client using credentials:

from ibm_watson_machine_learning import APIClient
wml_credentials = {
                   "url": "<URL>",
                   "username": "<USERNAME>",
                   "password" : "<PASSWORD>",
                   "instance_id": "openshift",
                   "version" : "4.0"

                  }

client = APIClient(wml_credentials)

Regarding <URL> value see: https://www.ibm.com/docs/en/cloud-paks/cp-data/3.5.0?topic=overview-authentication.

Example of creating the client using a token:

In IBM Cloud Pak® for Data version 4.0, user can authenticate with token set in the notebook environment.

access_token = os.environ['USER_ACCESS_TOKEN']
from ibm_watson_machine_learning import APIClient

wml_credentials = {
                   "url": "<URL>",
                   "token": access_token,
                   "instance_id": "openshift"
                   "version" : "4.0"
                  }
client = APIClient(wml_credentials)

                   "username": "<USERNAME>",
                   "password" : "<PASSWORD>",
                   "instance_id": "wml_local",
                   "version" : "1.1"

                  }

client = APIClient(wml_credentials)

Example of creating the client using a token:

access_token = os.environ['USER_ACCESS_TOKEN']
from ibm_watson_machine_learning import APIClient

wml_credentials = {
                   "url": "https://us-south.ml.cloud.ibm.com",
                   "token": access_token,
