This is an Elixir wrapper for the sentence-transformers Python library. It is used to get sentence embeddings from text, for example to use for semantic search.

It runs a Python process in a port, and therefore requires the system to have Python 3 installed. However no Python packages are needed, as requirements will be installed in a venv during the build process.

Add sentence_transformers to your list of dependencies in mix.exs:

def deps do
  [
    {:sentence_transformers, "~> 0.1.0"}
  ]
end
