Quick Start Guide

Using the Nstream SDK for Recommending Promotions

Introduction

The Nstream SDK is designed for building and managing neural network pipelines that incorporate large language models (LLMs) and stream processing capabilities. This guide will walk you through creating a simple but powerful neural network pipeline for generating insights from streaming data using the Nstream SDK.

Installation

To begin using the Nstream SDK in your projects, install it via pip with the following command:

pip install nstream

After installation, import the necessary modules and classes as follows:

from nstreamai_nstream_ai.core.nsinit import NsInit
from nstreamai_nstream_ai.core.nsnode import (
    NsNode, NsLink, NsProvider, NsProviderType, Nstream
)
from nstreamai_nstream_ai.core.nsneuron import NsNeuron, NstreamLLM
from nstreamai_nstream_ai.core.nsgraph import NsGraph
from utils.logger import logger
import sys

Core Module Imports

NsInit

Import: from nstreamai_nstream_ai.core.nsinit import NsInit

Description: This import brings in the NsInit class responsible for initializing and configuring the connection settings for the Nstream SDK.

Usage: It is used to set up the initial connection with the Nstream API using credentials like API key, username, and password.

NsNode, NsLink, NsProvider, NsProviderType, Nstream

Import: from nstreamai_nstream_ai.core.nsnode import NsNode, NsLink, NsProvider, NsProviderType, Nstream

Description: This import includes multiple classes that are fundamental to constructing nodes within an Nstream pipeline:

• NsNode: Represents a single node in the neural network graph.
• NsLink: Used to define connections between nodes and data sources or sinks.
• NsProvider: Specifies the data source or sink type.
• NsProviderType: Enumerates different types of data providers.
• Nstream: Might be used for additional functionality directly related to stream operations.

Usage: These are used to define and link the functional components of a neural network pipeline, such as data inputs, transformations, and outputs.

NsNeuron, NstreamLLM

Import: from nstreamai_nstream_ai.core.nsneuron import NsNeuron, NstreamLLM

Description: This import involves classes related to the neural network computation units within the SDK:

• NsNeuron: Represents a neuron unit which can execute specific neural network computations or models.
• NstreamLLM: Pertains to specific large language model configurations that can be deployed within neurons.

Usage: These are used to specify and configure the large language models that perform the actual analytics and insights generation in the pipeline.

NsGraph

Import: from nstreamai_nstream_ai.core.nsgraph import NsGraph

Description: Imports the NsGraph class, which manages the execution flow of neural network nodes defined with NsNode.

Usage: This class is crucial for defining the execution order and dependencies between nodes, as well as starting and stopping the data processing workflow.

Configuration

Start by initializing the SDK and connecting to the Nstream service:

try:
    logger.info("Starting main execution")
    conn = NsInit(
        api_key="your_api_key", 
        username="your_username", 
        password="your_password").connect()
    logger.info("Connected to NsInit")
except Exception as e:
    logger.exception(
        "Exception occurred while initializing NsInit"
        )
    print(e)
    sys.exit()

Building the Pipeline

Node 1: User Interaction Summarization and Insight Generation

Create the first node to summarize user interactions and generate insights:

prompt_event = Nstream.event()
ns_node_1_prompt_text = f"Generate a general insight using a user's data - {prompt_event}"
ns_node_1_context_transform_prompt_text = "Transform unstructured user data into a detailed JSON format..."

ns_node_1 = NsNode(
    node_name="GraphNode1",
    prompt=NsLink(
        socket=conn,
        provider=NsProvider(type=NsProviderType().Source).mongodb(),
        prompt_text=ns_node_1_prompt_text
    ),
    context=NsLink(
        socket=conn,
        provider=NsProvider(type=NsProviderType().Source).mongodb(),
        context_transform_prompt_text=ns_node_1_context_transform_prompt_text),
    neuron=NsNeuron(NstreamLLM.mistral_7b()),
    socket=conn)
logger.info("GraphNode1 configured")

Node 2: Personalized Recommendations

Set up the second node to use insights from Node 1 to generate personalized recommendations:

ns_node_2_prompt_text = "Based on general insight, provide a list of recommended promotional offers"
ns_node_2_context_transform_prompt_text = "Transform unstructured promotional data into a structured JSON format..."

ns_node_2 = NsNode(
    node_name="GraphNode2",
    prompt=NsLink(
        socket=conn,
        provider=NsProvider(
            type=NsProviderType().Source).mongodb(),prompt_text=ns_node_2_prompt_text),
    context=ns_node_1.output(
        context_transform_prompt_text=ns_node_2_context_transform_prompt_text),
    neuron=NsNeuron(NstreamLLM.llama2_7b()),
    socket=conn)
logger.info("GraphNode2 configured")

Running the Pipeline

Execute the configured pipeline and handle the output:

ns_graph_sink = NsLink(socket=conn, provider=NsProvider(type=NsProviderType().Sink).terminal())
logger.info("Graph sink configured")

ns_graph = NsGraph(conn).start(ns_node_1).end(ns_node_2).submit(ns_graph_sink)
logger.info("Graph execution started")

ns_graph.terminate(run_time=6)
logger.info("Graph execution terminated")

print("Execution Completed")
logger.info("Main execution completed")

Final code would look like this:

        logger.info("Connected to NsInit")
    except Exception as e:
        logger.exception("Exception occurred while initializing NsInit")
        print(e)
        sys.exit()
