Embedchain is a RAG framework to create data pipelines. It loads, indexes, retrieves and syncs all the data. It is available as an open source package and as a hosted platform solution.
This notebook shows how to use a retriever that uses Embedchain.

​
Installation

First you will need to install the embedchain package. You can install the package by running 
%pip install --upgrade --quiet  embedchain

​
Create New Retriever

EmbedchainRetriever has a static .create() factory method that takes the following arguments:
  • yaml_path: string optional — Path to the YAML configuration file. If not provided, a default configuration is used. You can browse the docs to explore various customization options.
# Setup API Key

import os
from getpass import getpass

if "OPENAI_API_KEY" not in os.environ:
    os.environ["OPENAI_API_KEY"] = getpass()

 ········

from langchain_community.retrievers import EmbedchainRetriever

# create a retriever with default options
retriever = EmbedchainRetriever.create()

# or if you want to customize, pass the yaml config path
# retriever = EmbedchainRetiever.create(yaml_path="config.yaml")

​
Add Data

In embedchain, you can as many supported data types as possible. You can browse our docs to see the data types supported. Embedchain automatically deduces the types of the data. So you can add a string, URL or local file path. 
retriever.add_texts(
    [
        "https://en.wikipedia.org/wiki/Elon_Musk",
        "https://www.forbes.com/profile/elon-musk",

You can now use the retrieve to find relevant documents given a query 
result = retriever.invoke("How many companies does Elon Musk run and name those?")
