How to Create a Lambda Layer for LangChain

AWS Lambda layers allow you to package libraries and dependencies that can be shared across multiple Lambda functions. This can help reduce deployment package sizes and make it easier to manage common dependencies across your serverless applications. In this blog post, we'll walk through how to create a Lambda layer for the LangChain library, which can be used for building applications with large language models.

Step 1: Pull the AWS SAM Build Image

First, we'll need to pull the AWS SAM build image for Python 3.10 from the public Amazon ECR registry. Open your terminal and run:

sudo docker pull public.ecr.aws/sam/build-python3.10:1.110.0-20240222205900

This is a gist of questions related to advancing your network engineer career.

• Best items to build a home lab on a budget? - @thelaymansterms

• I’d like to know what folks think of Azure monitoring tools. Networking is my weakest skill set, but I’m supporting more and more Azure based apps and environments and wanted to know folks real world experience with things like Azure Monitor or application insights. - @XDoesntCare

• How do I jump into the field with limited hands on experience? Currently hold the Net+, Sec+ and will(speaking it into existence) get the CCNA later this summer. - @SS_Zoeboy
