psquery 2.0

Predictive Services Query Client

This package allows you to query Turi Predictive Services.

Refer to https://turi.com/products/predictive-services/docs/userguide/connecting.html#psquery for detailed information regarding how to use this client.

This package only includes the config.py and query_client.py from the full Predictive Services client psclient.

Connecting

In order to connect, you need to know the query endpoint URL and your key. An API key or an admin key is sufficient to query the Predictive Services. An API key may have limitations on which endpoints it can query. Consult with your system administrator to obtain the appropriate key.

The psquery.connect function is used to connect to the service.:

import psquery
conn = psquery.connect(query_endpoint_URL, key_id)

Please consult the connect function documentation for details on alternative methods of specifying these parameters during connection.

Querying

Once you have connected, you can query by specifying the endpoint you want to query and the parameters. Keep in mind that your key must have sufficient privileges to access the endpoint. Admin keys can access all endpoints, but API keys must be specifically allowed by endpoint name.:

response = conn.query('add', 1, 2)

The response is a dict with the following keys and values.:

{u'node': u'...', u'uuid': u'...', u'version': 1, u'from_cache': False, u'model': u'add', u'response': 3}

Please see the query method documentation for more details.

Feedback

If the endpoint allows it, you can specify feedback::

conn.feedback(response['uuid'], success=True)

Please see the feedback method documentation for more details.
