LangChain in your Pocket

Chapter 2: Hello World

In the previous chapter, we had a good understanding of what LangChain is. This chapter will start by exploring LangChain’s potential to build a few baseline applications using LLMs from different domains to understand its utilities. For now, we won’t be focussing on understanding the codes, but just exploring what LangChain can do. I am assuming most of the readers are well-versed in Python to get started.

2.1 Setting up LangChain

To get started with LangChain, you first need to have Python>=3.8.1 in your local system. If you already have it, you can run the below code in your system (jupyter notebook preferred).

 

!pip install langchain==0.0.343 openai==1.3.6
