3. dotenv can also be used to setup the key. Use the env.example to create env file

💻 Running Locally

1. Clone the repository📂

git clone https://github.com/amjadraza/dlai-langchain.git

2. Install dependencies with Poetry and activate virtual environment🔨

poetry install
poetry shell

3. Copy and Modify env.example to .env

Generate the HF API Key to be able to hosted models for inference and set the variables accordingly.

4. Run the JupyterLab server🚀

jupyter lab

Run Notebooks using Docker

This project includes Dockerfile to run the app in Docker container. In order to optimise the Docker Image size and building time with cache techniques, I have follow tricks in below Article https://medium.com/@albertazzir/blazing-fast-python-docker-builds-with-poetry-a78a66f5aed0

Build the docker container

docker build . -t dlai-langchain:latest

To generate Image with DOCKER_BUILDKIT, follow below command

DOCKER_BUILDKIT=1 docker build --target=runtime . -t dlai-langchain:latest

1. Run the docker container directly

docker run -d --name dlai-langchain -p 8888:8888 dlai-langchain:latest

2. Run the docker container using docker-compose (Recommended)

docker-compose up

Make sure to include the .env SECRETS file when running with docker-compose with your own Keys.

Report Feedbacks

As dlai-hf-course:latest is a template project with minimal example. Report issues if you face any.
