# README for Evaluation

## 🌟 Overview

This script provides an evaluation pipeline for `ScienceQA`.

## 🗂️ Data Preparation

Before starting to download the data, please create the `InternVL/internvl_chat/data` folder.

### ScienceQA

Follow the instructions below to prepare the data:

```shell
# Step 1: Create the data directory
mkdir -p data/scienceqa/images && cd data/scienceqa/images

# Step 2: Download images
wget https://scienceqa.s3.us-west-1.amazonaws.com/images/test.zip && unzip test.zip

cd ..

# Step 3: Download original questions
wget https://github.com/lupantech/ScienceQA/blob/main/data/scienceqa/problems.json

# Step 4: Download converted files
wget https://ofasys-wlcb.oss-cn-wulanchabu.aliyuncs.com/Qwen-VL/evaluation/scienceqa/scienceqa_test_img.jsonl

cd ../..
```

After preparation is complete, the directory structure is:

```shell
data/scienceqa
├── images
├── problems.json
└── scienceqa_test_img.jsonl
```

## 🏃 Evaluation Execution

> ⚠️ Note: For testing InternVL (1.5, 2.0, 2.5, and later versions), always enable `--dynamic` to perform dynamic resolution testing.

To run the evaluation, execute the following command on an 8-GPU setup:

```shell
torchrun --nproc_per_node=8 eval/scienceqa/evaluate_scienceqa.py --checkpoint ${CHECKPOINT} --dynamic
```

Alternatively, you can run the following simplified command:

```shell
GPUS=8 sh evaluate.sh ${CHECKPOINT} scienceqa --dynamic
```

### Arguments

The following arguments can be configured for the evaluation script:

| Argument         | Type   | Default      | Description                                                                                                       |
| ---------------- | ------ | ------------ | ----------------------------------------------------------------------------------------------------------------- |
| `--checkpoint`   | `str`  | `''`         | Path to the model checkpoint.                                                                                     |
| `--datasets`     | `str`  | `'sqa_test'` | Comma-separated list of datasets to evaluate.                                                                     |
| `--dynamic`      | `flag` | `False`      | Enables dynamic high resolution preprocessing.                                                                    |
| `--max-num`      | `int`  | `6`          | Maximum tile number for dynamic high resolution.                                                                  |
| `--load-in-8bit` | `flag` | `False`      | Loads the model weights in 8-bit precision.                                                                       |
| `--auto`         | `flag` | `False`      | Automatically splits a large model across 8 GPUs when needed, useful for models too large to fit on a single GPU. |
