Installation
Langformers requires Python 3.10 or later. Its installation is simple!
Note
It’s highly recommended to install Langformers in a virtual environment to avoid dependency conflicts. Follow the Platform-specific Instructions.
To install Langformers globally:
pip install -U langformers
This installs the latest version with core dependencies. If you need support for specific features (e.g., FAISS for vector search), you can install optional dependencies as well.
Optional Dependencies
Langformers includes optional integrations you can install depending on your use case:
For FAISS support:
pip install -U langformers[faiss]For ChromaDB support:
pip install -U langformers[chromadb]For Pinecone support:
pip install -U langformers[pinecone]To install all optional features:
pip install -U langformers[all]
Important
If you use zsh, wrap everything after pip install in quotes to avoid shell interpretation. Example:
pip install "langformers[faiss]"
This applies to zsh and any shell that might treat [] as a glob pattern.
