Introduction to Pinecone Python SDK

The Pinecone Python SDK is the official software development kit designed to facilitate seamless interaction with the Pinecone vector database. With its robust features and user-friendly interface, developers can efficiently manage and query vector data, making it an essential tool for machine learning and AI applications.

In this blog post, we will explore the main features of the Pinecone Python SDK, guide you through the installation process, provide usage examples, and discuss community contributions and future plans.

Key Features of Pinecone Python SDK

• Easy Installation: The SDK can be installed via pip, uv, or poetry, making it accessible for various development environments.
• Asynchronous Support: With the pinecone[asyncio] extra, developers can leverage asynchronous programming for improved performance.
• GRPC Integration: The SDK supports GRPC for faster data calls, enhancing the efficiency of operations like upsert and query.
• Comprehensive Documentation: Detailed guides and reference documentation are available to assist developers in utilizing the SDK effectively.
• Community Support: Engage with the Pinecone community for troubleshooting, feedback, and contributions.

Technical Architecture and Implementation

The Pinecone Python SDK is built to interact with the Pinecone vector database, which is designed for high-performance vector similarity search. The SDK abstracts the complexities of API calls, allowing developers to focus on building applications without worrying about the underlying infrastructure.

Key components of the SDK include:

• Pinecone Client: The main interface for interacting with the Pinecone service, allowing users to create indexes, upsert vectors, and perform queries.
• Index Management: Functions to create, describe, and delete indexes, enabling efficient organization of vector data.
• Vector Operations: Methods for upserting, querying, and managing vectors, including support for metadata.

Installation Process

To get started with the Pinecone Python SDK, follow these simple installation steps:

Prerequisites

• Python 3.9 or greater is required.
• Sign up for a Pinecone account and obtain your API key from the Pinecone console dashboard at Pinecone Console.

Installing the SDK

You can install the Pinecone SDK using pip:

# Install the latest version
pip3 install pinecone

# Install with optional dependencies
pip3 install "pinecone[asyncio,grpc]"

Alternatively, you can use uv or poetry for installation:

# Using uv
uv add pinecone

# Using poetry
poetry add pinecone

Usage Examples and API Overview

Once the SDK is installed, you can start using it to manage your vector data. Below are some common usage examples:

Bringing Your Own Vectors to Pinecone

from pinecone import Pinecone, ServerlessSpec, CloudProvider, AwsRegion, VectorType

# Instantiate the Pinecone client
pc = Pinecone(api_key='YOUR_API_KEY')

# Create an index
index_config = pc.create_index(
    name="index-name",
    dimension=1536,
    spec=ServerlessSpec(
        cloud=CloudProvider.AWS,
        region=AwsRegion.US_EAST_1
    ),
    vector_type=VectorType.DENSE
)

# Instantiate an Index client
idx = pc.Index(host=index_config.host)

# Upsert embeddings
idx.upsert(
    vectors=[
        ("id1", [0.1, 0.2, 0.3, 0.4, ...], {"metadata_key": "value1"}),
        ("id2", [0.2, 0.3, 0.4, 0.5, ...], {"metadata_key": "value2"}),
    ],
    namespace="example-namespace"
)

# Query your index using an embedding
query_embedding = [...] # list should have length == index dimension
idx.query(
    vector=query_embedding,
    top_k=10,
    include_metadata=True,
    filter={"metadata_key": { "$eq": "value1" }}
)

Using Pinecone Integrated Inference

from pinecone import Pinecone, CloudProvider, AwsRegion, EmbedModel

# Instantiate the Pinecone client
pc = Pinecone(api_key="<>")

# Create an index configured for use with a particular model
index_config = pc.create_index_for_model(
    name="my-model-index",
    cloud=CloudProvider.AWS,
    region=AwsRegion.US_EAST_1,
    embed=IndexEmbed(
        model=EmbedModel.Multilingual_E5_Large,
        field_map={"text": "my_text_field"}
    )
)

# Instantiate an Index client
idx = pc.Index(host=index_config.host)

# Upsert records
idx.upsert_records(
    namespace="my-namespace",
    records=[
        {
            "_id": "test1",
            "my_text_field": "Apple is a popular fruit known for its sweetness and crisp texture.",
        },
        {
            "_id": "test2",
            "my_text_field": "The tech company Apple is known for its innovative products like the iPhone.",
        },
    ],
)

# Search for similar records
from pinecone import SearchQuery, SearchRerank, RerankModel

response = index.search_records(
    namespace="my-namespace",
    query=SearchQuery(
        inputs={
            "text": "Apple corporation",
        },
        top_k=3
    ),
    rerank=SearchRerank(
        model=RerankModel.Bge_Reranker_V2_M3,
        rank_fields=["my_text_field"],
        top_n=3,
    ),
)
