Use watsonx.ai python SDK to manage Prompt Template assets and create deployment

Disclaimers

  • Use only Projects and Spaces that are available in watsonx context.

Notebook content

This notebook contains the steps and code to demonstrate support for Prompt Template inference and their deployments.

Some familiarity with Python is helpful. This notebook uses Python 3.10.

Learning goal

The goal of this notebook is to demonstrate how to create a Prompt Template asset and deployment pointing on it. In general, a Prompt Template is a pattern for generating prompts for language models. A template may contain instruction, input/output prefixes, few-shot examples and appropriate context that may vary depending on different tasks.

Contents

This notebook contains the following parts:

Set up the environment

Before you use the sample code in this notebook, you must perform the following setup tasks:

  • Contact with your Cloud Pack for Data administrator and ask him for your account credentials

Install dependecies

!pip install "ibm-watsonx-ai>=0.2.3" | tail -n 1

Connection to WML

Authenticate the Watson Machine Learning service on IBM Cloud Pack for Data. You need to provide platform url, your username and api_key.

username = 'PASTE YOUR USERNAME HERE' api_key = 'PASTE YOUR API_KEY HERE' url = 'PASTE THE PLATFORM URL HERE'
credentials = { "username": username, "apikey": api_key, "url": url, "instance_id": 'openshift', "version": '4.8' }

Alternatively you can use username and password to authenticate WML services.

credentials = { "username": ***, "password": ***, "url": ***, "instance_id": 'openshift', "version": '4.8' }

Defining the project id

The Prompt Template requires project id that provides the context for the call. We will obtain the id from the project in which this notebook runs. Otherwise, please provide the project id.

import os try: project_id = os.environ["PROJECT_ID"] except KeyError: project_id = input("Please enter your project_id (hit enter): ")

Prompt Template on watsonx.ai

from ibm_watsonx_ai.foundation_models.prompts import PromptTemplateManager, PromptTemplate from ibm_watsonx_ai.foundation_models.utils.enums import ModelTypes, DecodingMethods, PromptTemplateFormats from ibm_watsonx_ai.metanames import GenTextParamsMetaNames as GenParams

Instantiate PromptTemplateManager

prompt_mgr = PromptTemplateManager( credentials=credentials, project_id=project_id )

Create a Prompt Template object and store it in the project

We use a PromptTemplate object to store the properties of a newly created prompt template. Prompt text is composed of the instruction, input/output prefixes, few-shot examples and input text. All of the mentioned fields may contain placeholders ({...}) with input variables and for the template to be valid, these input variables must be also specified in input_variables parameter.

prompt_template = PromptTemplate(name="New prompt", model_id=ModelTypes.FLAN_T5_XXL, model_params = {GenParams.DECODING_METHOD: "sample"}, description="My example", task_ids=["generation"], input_variables=["object"], instruction="Answer on the following question", input_prefix="Human", output_prefix="Assistant", input_text="What is {object} and how does it work?", examples=[["What is a loan and how does it work?", "A loan is a debt that is repaid with interest over time."]] )

Using store_prompt(prompt_template_id) method, one can store newly created prompt template in your ptoject.

stored_prompt_template = prompt_mgr.store_prompt(prompt_template=prompt_template)
print(f"Asset id: {stored_prompt_template.prompt_id}") print(f"Is it a template?: {stored_prompt_template.is_template}")
Asset id: 87e3587a-8f38-4297-8c5b-575c9b6b3f40 Is it a template?: True

We can also store a template which is a langchain Prompt Template object.

!pip install langchain | tail -n 1
from langchain.prompts import PromptTemplate as LcPromptTemplate langchain_prompt_template = LcPromptTemplate(template="What is {object} and how does it work?", input_variables=["object"]) stored_prompt_template_lc = prompt_mgr.store_prompt(prompt_template=langchain_prompt_template) print(f"Asset id: {stored_prompt_template_lc.prompt_id}")
Asset id: fc6f6d1b-e30f-4909-9a41-519b59ae6915

Manage Prompt Templates

prompt_mgr.list()

To retrive Prompt Template asset from project and return string that contains Prompt Template input we use load_prompt(prompt_template_id, astype=...). Returned input string is composed of the fields: instruction, input_prefix, output_prefix, examples and input_text. After substituting prompt variables, one can evaluate a language model on the obtained string.

prompt_text = prompt_mgr.load_prompt(prompt_id=stored_prompt_template.prompt_id, astype=PromptTemplateFormats.STRING) print(prompt_text)
Answer on the following question Human What is a loan and how does it work? Assistant A loan is a debt that is repaid with interest over time. Human What is {object} and how does it work? Assistant

To update Prompt Template data use prompt_mgr.update_prompt method.

prompt_with_new_instruction = PromptTemplate(instruction="Answer on the following question in a concise way.") prompt_mgr.update_prompt(prompt_id=stored_prompt_template.prompt_id, prompt_template=prompt_with_new_instruction) prompt_text = prompt_mgr.load_prompt(prompt_id=stored_prompt_template.prompt_id, astype=PromptTemplateFormats.STRING) print(prompt_text)
Answer on the following question in a concise way. Human What is a loan and how does it work? Assistant A loan is a debt that is repaid with interest over time. Human What is {object} and how does it work? Assistant

Furthermore, to get information about locked state of Prompt Template run following method

prompt_mgr.get_lock(prompt_id=stored_prompt_template.prompt_id)
{'locked': True, 'locked_by': '1000330999', 'lock_type': 'edit'}

Using lock or unlock method, one can change locked state of Prompt Template asset.

prompt_mgr.unlock(prompt_id=stored_prompt_template_lc.prompt_id)
{'locked': False}

Once the prompt template is unlocked it can be deleted. You can also use the list method to check the available prompt templates (passing limit=2 parameter will return only 2 recently created templates).

print(f"Id of the Prompt Template asset that will be deleted: {stored_prompt_template_lc.prompt_id}") prompt_mgr.delete_prompt(prompt_id=stored_prompt_template_lc.prompt_id) prompt_mgr.list(limit=2)
Id of the Prompt Template asset that will be deleted: fc6f6d1b-e30f-4909-9a41-519b59ae6915

Deployment pointing to Prompt Template

To create deployment pointing to a Prompt template asset we have to initialized APIClient object.

from ibm_watsonx_ai import APIClient client = APIClient(wml_credentials=credentials) client.set.default_project(project_id)
'SUCCESS'

In the deployment exmaple we will use the prompt with the following input

prompt_input_text = prompt_mgr.load_prompt(prompt_id=stored_prompt_template.prompt_id, astype=PromptTemplateFormats.STRING) print(prompt_input_text)
Answer on the following question in a concise way. Human What is a loan and how does it work? Assistant A loan is a debt that is repaid with interest over time. Human What is {object} and how does it work? Assistant

Now, we create deployment providing the id of Prompt Template asset and meta props.

meta_props = { client.deployments.ConfigurationMetaNames.NAME: "SAMPLE DEPLOYMENT PROMPT TEMPLATE", client.deployments.ConfigurationMetaNames.ONLINE: {}, client.deployments.ConfigurationMetaNames.BASE_MODEL_ID: "ibm/granite-13b-chat-v2"} deployment_details = client.deployments.create(artifact_uid=stored_prompt_template.prompt_id, meta_props=meta_props)

Substitute prompt variables and generate text

deployment_id = deployment_details.get("metadata", {}).get("id")
client.deployments.generate_text(deployment_id, params={"prompt_variables": {"object": "a mortgage"}, GenParams.DECODING_METHOD: DecodingMethods.GREEDY, GenParams.STOP_SEQUENCES: ['\n\n'], GenParams.MAX_NEW_TOKENS: 50})
Note: online_url is deprecated and will be removed in a future release. Use serving_urls instead.
' A mortgage is a type of loan used to buy a home. When you take out a mortgage, you borrow money from a bank or other financial institution to pay for the home. The home serves as collateral for the loan, which means that if you'

Generate text using ModelInference

You can also generate text based on your Prompt Template deployment using ModelInference class.

from ibm_watsonx_ai.foundation_models import ModelInference
model_inference = ModelInference(deployment_id=deployment_id, credentials=credentials, project_id=project_id)
Note: online_url is deprecated and will be removed in a future release. Use serving_urls instead.
model_inference.generate_text(params={"prompt_variables": {"object": "a mortgage"}, GenParams.DECODING_METHOD: DecodingMethods.GREEDY, GenParams.STOP_SEQUENCES: ['\n\n'], GenParams.MAX_NEW_TOKENS: 50})
' A mortgage is a type of loan used to buy a home. When you take out a mortgage, you borrow money from a bank or other financial institution to pay for the home. The home serves as collateral for the loan, which means that if you'
