text: Tigris eliminates the infrastructure complexity of managing, operating, and synchronizing multiple tools, allowing you to focus on building great applications instead.This notebook guides you how to use Tigris as your VectorStorePre requisitesAn OpenAI account. You can sign up for an account hereSign up for a free Tigris account. Once you have signed up for the Tigris account, create a new project called vectordemo. Next, make a note of the Uri for the region you've created your project in, the clientId and clientSecret. You can get all this information from the Application Keys section of the project.Let's first install our dependencies:pip install tigrisdb openapi-schema-pydantic openai tiktokenWe will load the OpenAI api key and Tigris credentials in our environmentimport osimport getpassos.environ["OPENAI_API_KEY"] = getpass.getpass("OpenAI API Key:")os.environ["TIGRIS_PROJECT"] = getpass.getpass("Tigris Project Name:")os.environ["TIGRIS_CLIENT_ID"] = getpass.getpass("Tigris Client Id:")os.environ["TIGRIS_CLIENT_SECRET"] = getpass.getpass("Tigris Client Secret:")from langchain.embeddings.openai import OpenAIEmbeddingsfrom langchain.text_splitter import CharacterTextSplitterfrom langchain.vectorstores import Tigrisfrom langchain.document_loaders import TextLoaderInitialize Tigris vector storeâ€‹Let's import our test dataset:loader = TextLoader("../../../state_of_the_union.txt")documents = loader.load()text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)docs = text_splitter.split_documents(documents)embeddings = OpenAIEmbeddings()vector_store = Tigris.from_documents(docs, embeddings, index_name="my_embeddings")Similarity Searchâ€‹query = "What did the president
