EvalSense: LLM Evaluation

About

This repository holds a Python package enabling systematic evaluation of large language models (LLMs) on open-ended generation tasks, with a particular focus on healthcare and summarisation. It also includes supplementary documentation and assets related to the NHS England project on LLM evaluation, such as the code for an interactive LLM evaluation guide (located in the guide/ directory). You can find more information about the project in the original project proposal.

Note: Only public or fake data are shared in this repository.

Project Stucture

• The main code for the EvalSense Python package can be found under evalsense/.
• The accompanying documentation is available in the docs/ folder.
• Code for the interactive LLM evaluation guide is located under guide/.
• Jupyter notebooks with the evaluation experiments and examples are located under notebooks/.

Getting Started

Installation

You can install the project using pip by running the following command:

pip install evalsense

This will install the latest released version of the package from PyPI.

Depending on your use-case, you may want to install additional optional dependencies from the following groups:

• interactive: For running experiments interactively in Jupyter notebooks (only needed if you don't already have the necessary libraries installed).
• transformers: For using models and metrics requiring the Hugging Face Transformers library.
• vllm: For using models and metrics requiring vLLM.
• local: For installing all local model dependencies (currently includes transformers and vllm).
• all: For installing all optional dependencies.

For example, if you want to use EvalSense with Jupyter notebooks (interactive) and Hugging Face Transformers (transformers), you can run:

pip install evalsense[interactive,transformers]

Installation for Development

To install the project for local development, you can follow the steps below:

To clone the repo:

git clone [e-mail]:nhsengland/evalsense.git

To setup the Python environment for the project:

• Install uv if it's not installed already
• uv sync --all-extras
• source .venv/bin/activate
• pre-commit install

To setup the Node environment for the LLM evaluation guide (located under guide/):

• Install node if it's not installed already
• Change to the guide/ directory (cd guide)
• npm install
• npm run start to run the development server

See also the separate README.md for the guide.

Usage

For an example illustrating the usage of EvalSense, please check the Demo notebook under the notebooks/ folder.
