Langchain Udemy

This is my code for the Damien Benveniste Langchain Udemy course.

This code is here as great reference in case something does not work, but it worked for me, or was fixed by me while doing the course.

Setup

1. Create virtualenv for python@3.10 and activate it

# For MacOS
virtualenv -p /opt/homebrew/bin/python3.10 venv

source ./venv/bin/activate

2. Install deps

pip install -r requirements.txt

3. Rename example.env to .env and fill API key details

Additional Notes

• FAISS is failing to install

Lower python version to 3.10. Or creat venv that is 3.10.

• Failing to install "python-poppler" on MacOS?

Install system dependencies:

brew install pkg-config poppler

• GitLSF is missing (MacOS)

brew install git-lfs

• Missing tesseract

brew install tesseract

• Pygraphviz is failing to install

See https://stackoverflow.com/questions/40266604/pip-install-pygraphviz-fails-failed-building-wheel-for-pygraphviz

  --config-settings="--global-option=build_ext" \
  --config-settings="--global-option=-I$(brew --prefix graphviz)/include/" \
