Analysis of Twitter the-algorithm source code with LangChain, GPT4 and Deep Lake#
In this tutorial, we are going to use Langchain + Deep Lake with GPT4 to analyze the code base of the twitter algorithm.
!python3 -m pip install --upgrade langchain deeplake openai tiktoken
Define OpenAI embeddings, Deep Lake multi-modal vector store api and authenticate. For full documentation of Deep Lake please follow docs and API reference.
Authenticate into Deep Lake if you want to create your own dataset and publish it. You can get an API key from the platform
import os
import getpass
from langchain.embeddings.openai import OpenAIEmbeddings
from langchain.vectorstores import DeepLake
os.environ['OPENAI_API_KEY'] = getpass.getpass('OpenAI API Key:')
os.environ['ACTIVELOOP_TOKEN'] = getpass.getpass('Activeloop Token:')
embeddings = OpenAIEmbeddings(disallowed_special=())
disallowed_special=() is required to avoid Exception: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte from tiktoken for some repositories
1. Index the code base (optional)#
You can directly skip this part and directly jump into using already indexed dataset. To begin with, first we will clone the repository, then parse and chunk the code base and use OpenAI indexing.
!git clone https://github.com/twitter/the-algorithm # replace any repository of your choice 
Load all files inside the repository
import os
from langchain.document_loaders import TextLoader
root_dir = './the-algorithm'
