-`poetry shell` - this command creates a virtual environment, which keeps installed packages contained to this project
-`poetry install` - this will install the core package requirements
- (Optional) `poetry install --with dev,docs` - this will install all dependencies needed for most local development
## Optional Dependencies
By default LlamaIndex installs a core set of dependencies; we also provide a convenient way to install commonly-required optional dependencies. These are currently in three sets:
-`pip install llama-index[local_models]` installs tools useful for private LLMs, local inference, and HuggingFace models
-`pip install llama-index[postgres]` is useful if you are working with Postgres, PGVector or Supabase
-`pip install llama-index[query_tools]` gives you tools for hybrid search, structured outputs, and node post-processing
