## Why `lmms-eval`?

We're on an exciting journey toward creating Artificial General Intelligence (AGI), much like the enthusiasm of the 1960s moon landing. This journey is powered by advanced large language models (LLMs) and large multimodal models (LMMs), which are complex systems capable of understanding, learning, and performing a wide variety of human tasks.

To gauge how advanced these models are, we use a variety of evaluation benchmarks. These benchmarks are tools that help us understand the capabilities of these models, showing us how close we are to achieving AGI. However, finding and using these benchmarks is a big challenge. The necessary benchmarks and datasets are spread out and hidden in various places like Google Drive, Dropbox, and different school and research lab websites. It feels like we're on a treasure hunt, but the maps are scattered everywhere.

In the field of language models, there has been a valuable precedent set by the work of [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness). They offer integrated data and model interfaces, enabling rapid evaluation of language models and serving as the backend support framework for the [open-llm-leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard), and has gradually become the underlying ecosystem of the era of foundation models.

We humbly obsorbed the exquisite and efficient design of [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness) and introduce **lmms-eval**, an evaluation framework meticulously crafted for consistent and efficient evaluation of LMM.

## Installation

For direct usage, you can install the package from Git by running the following command:
```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
uv venv eval
uv venv --python 3.12
source eval/bin/activate
uv pip install git+https://github.com/EvolvingLMMs-Lab/lmms-eval.git
```

For development, you can install the package by cloning the repository and running the following command:
```bash
git clone https://github.com/EvolvingLMMs-Lab/lmms-eval
cd lmms-eval
uv venv dev
source dev/bin/activate
uv pip install -e .
```

<details>
<summary>Reproduction of LLaVA-1.5's paper results</summary>

You can check the [environment install script](miscs/repr_scripts.sh) and [torch environment info](miscs/repr_torch_envs.txt) to **reproduce LLaVA-1.5's paper results**. We found torch/cuda versions difference would cause small variations in the results, we provide the [results check](miscs/llava_result_check.md) with different environments.

</details>

If you want to test on caption dataset such as `coco`, `refcoco`, and `nocaps`, you will need to have `java==1.8.0` to let pycocoeval api to work. If you don't have it, you can install by using conda
```
conda install openjdk=8
```
you can then check your java version by `java -version`

<summary>Comprehensive Evaluation Results of LLaVA Family Models</summary>
<br>

As demonstrated by the extensive table below, we aim to provide detailed information for readers to understand the datasets included in lmms-eval and some specific details about these datasets (we remain grateful for any corrections readers may have during our evaluation process).

We provide a Google Sheet for the detailed results of the LLaVA series models on different datasets. You can access the sheet [here](https://docs.google.com/spreadsheets/d/1a5ImfdKATDI8T7Cwh6eH-bEsnQFzanFraFUgcS9KHWc/edit?usp=sharing). It's a live sheet, and we are updating it with new results.

If you want to test [VILA](https://github.com/NVlabs/VILA), you should install the following dependencies:

```bash
pip install s2wrapper@git+https://github.com/bfshi/scaling_on_scales
```

Our Development will be continuing on the main branch, and we encourage you to give us feedback on what features are desired and how to improve the library further, or ask questions, either in issues or PRs on GitHub.

## Acknowledgement

lmms_eval is a fork of [lm-eval-harness](https://github.com/EleutherAI/lm-evaluation-harness). We recommend you to read through the [docs of lm-eval-harness](https://github.com/EleutherAI/lm-evaluation-harness/tree/main/docs) for relevant information.

Below are the changes we made to the original API:
- Build context now only pass in idx and process image and doc during the model responding phase. This is due to the fact that dataset now contains lots of images and we can't store them in the doc like the original lm-eval-harness other wise the cpu memory would explode.
- Instance.args (lmms_eval/api/instance.py) now contains a list of images to be inputted to lmms.
- lm-eval-harness supports all HF language models as single model class. Currently this is not possible of lmms because the input/output format of lmms in HF are not yet unified. Thererfore, we have to create a new class for each lmms model. This is not ideal and we will try to unify them in the future.
