+# Config System
+
+By default, VLMEvalKit launches the evaluation by setting the model name(s) (defined in `/vlmeval/config.py`) and dataset name(s) (defined in `vlmeval/dataset/__init__.py` or `vlmeval/dataset/video_dataset_config.py`) in the `run.py` script with the `--model` and `--data` arguments. Such approach is simple and efficient in most scenarios, however, it may not be flexible enough when the user wants to evaluate multiple models / datasets with different settings.
+
+To address this, VLMEvalKit provides a more flexible config system. The user can specify the model and dataset settings in a json file, and pass the path to the config file to the `run.py` script with the `--config` argument. Here is a sample config json:
+
+```json
+{
+    "model": {
+        "GPT4o_20240806_T00_HIGH": {
+            "class": "GPT4V",
+            "model": "gpt-4o-2024-08-06",
+            "temperature": 0,
+            "img_detail": "high"
+        },
+        "GPT4o_20240806_T10_Low": {
+            "class": "GPT4V",
+            "model": "gpt-4o-2024-08-06",
+            "temperature": 1.0,
+            "img_detail": "low"
+        },
+        "GPT4o_20241120": {}
+    },
+    "data": {
+        "MME-RealWorld-Lite": {
+            "class": "MMERealWorld",
+            "dataset": "MME-RealWorld-Lite"
+        },
+        "MMBench_DEV_EN_V11": {
+            "class": "ImageMCQDataset",
+            "dataset": "MMBench_DEV_EN_V11"
+        },
+        "MMBench_Video_8frame_nopack":{},
+        "Video-MME_16frame_subs": {
+            "class": "VideoMME",
+            "dataset": "Video-MME",
+            "nframe": 16,
+            "use_subtitle": true
+        }
+    }
+}
+```
+
+Explanation of the config json:
+
+1. Now we support two fields: `model` and `data`, each of which is a dictionary. The key of the dictionary is the name of the model / dataset (set by the user), and the value is the setting of the model / dataset.
+2. For items in `model`, the value is a dictionary containing the following keys:
+    - `class`: The class name of the model, which should be a class name defined in `vlmeval/vlm/__init__.py` (open-source models) or `vlmeval/api/__init__.py` (API models).
+    - Other kwargs: Other kwargs are model-specific parameters, please refer to the definition of the model class for detailed usage. For example, `model`, `temperature`, `img_detail` are arguments of the `GPT4V` class. It's noteworthy that the `model` argument is required by most model classes.
+    - Tip: The defined model in the `supported_VLM` of `vlmeval/config.py` can be used as a shortcut, for example, `GPT4o_20241120: {}` is equivalent to `GPT4o_20241120: {'class': 'GPT4V', 'model': 'gpt-4o-2024-11-20', 'temperature': 0, 'img_size': -1, 'img_detail': 'high', 'retry': 10, 'verbose': False}`
+3. For the dictionary `data`, we suggest users to use the official dataset name as the key (or part of the key), since we frequently determine the post-processing / judging settings based on the dataset name. For items in `data`, the value is a dictionary containing the following keys:
+    - `class`: The class name of the dataset, which should be a class name defined in `vlmeval/dataset/__init__.py`.
+    - Other kwargs: Other kwargs are dataset-specific parameters, please refer to the definition of the dataset class for detailed usage. Typically, the `dataset` argument is required by most dataset classes. It's noteworthy that the `nframe` argument or `fps` argument is required by most video dataset classes.
+    - Tip: The defined dataset in the `supported_video_datasets` of `vlmeval/dataset/video_dataset_config.py` can be used as a shortcut, for example, `MMBench_Video_8frame_nopack: {}` is equivalent to `MMBench_Video_8frame_nopack: {'class': 'MMBenchVideo', 'dataset': 'MMBench-Video', 'nframe': 8, 'pack': False}`.
+Saving the example config json to `config.json`, you can launch the evaluation by:
+
+```bash
+python run.py --config config.json
+```
+
+That will generate the following output files under the working directory `$WORK_DIR` (Following the format `{$WORK_DIR}/{$MODEL_NAME}/{$MODEL_NAME}_{$DATASET_NAME}_*`):
+
+- `$WORK_DIR/GPT4o_20240806_T00_HIGH/GPT4o_20240806_T00_HIGH_MME-RealWorld-Lite*`
+- `$WORK_DIR/GPT4o_20240806_T10_Low/GPT4o_20240806_T10_Low_MME-RealWorld-Lite*`

+# 快速开始
+
+在运行评测脚本之前，你需要先**配置** VLMs，并正确设置模型路径。然后你可以使用脚本 `run.py` 进行多个VLMs和基准测试的推理和评估。
+
+## 第0步 安装和设置必要的密钥
+
+**安装**
+
+```bash
+git clone https://github.com/open-compass/VLMEvalKit.git
+cd VLMEvalKit
+pip install -e .
+```
+
+**设置密钥**
+
+要使用 API 模型（如 GPT-4v, Gemini-Pro-V 等）进行推理，或使用 LLM API 作为**评判者或选择提取器**，你需要首先设置 API 密钥。如果你设置了密钥，VLMEvalKit 将使用一个评判 LLM 从输出中提取答案，否则它将使用**精确匹配模式**（在输出字符串中查找 "Yes", "No", "A", "B", "C"...）。**精确匹配模式只能应用于是或否任务和多项选择任务。**
+
+- 你可以将所需的密钥放在 `$VLMEvalKit/.env` 中，或直接将它们设置为环境变量。如果你选择创建 `.env` 文件，其内容将如下所示：
+
+  ```bash
+  # .env 文件，将其放置在 $VLMEvalKit 下
+  # 专有 VLMs 的 API 密钥
+  # QwenVL APIs
+  DASHSCOPE_API_KEY=
+  # Gemini w. Google Cloud Backends
+  GOOGLE_API_KEY=
+  # OpenAI API
+  OPENAI_API_KEY=
+  OPENAI_API_BASE=
+  # StepAI API
+  STEPAI_API_KEY=
+  # REKA API
+  REKA_API_KEY=
+  # GLMV API
+  GLMV_API_KEY=
+  # CongRong API
+  CW_API_BASE=
+  CW_API_KEY=
+  # SenseNova API
+  SENSENOVA_API_KEY=
+  # Hunyuan-Vision API
+  HUNYUAN_SECRET_KEY=
+  HUNYUAN_SECRET_ID=
+  # LMDeploy API
+  LMDEPLOY_API_BASE=
+  # 你可以设置一个评估时代理，评估阶段产生的 API 调用将通过这个代理进行
+  EVAL_PROXY=
+  ```
+
+- 如果需要使用 API 在对应键值空白处填写上你的密钥。这些 API 密钥将在进行推理和评估时自动加载。
+## 第1步 配置
+
+**VLM 配置**：所有 VLMs 都在 `vlmeval/config.py` 中配置。对于某些 VLMs（如 MiniGPT-4、LLaVA-v1-7B），需要额外的配置（在配置文件中配置代码 / 模型权重根目录）。在评估时，你应该使用 `vlmeval/config.py` 中 `supported_VLM` 指定的模型名称来选择 VLM。确保在开始评估之前，你可以成功使用 VLM 进行推理，使用以下命令 `vlmutil check {MODEL_NAME}`。
+
+## 第2步 评测
+
+**新功能!!!** 我们集成了一个新的配置系统，以实现更灵活的评估设置。查看[文档](/docs/zh-CN/ConfigSystem.md)或运行`python run.py --help`了解更多详情 🔥🔥🔥
+
+我们使用 `run.py` 进行评估。你可以使用 `$VLMEvalKit/run.py` 或创建脚本的软链接运行（以便在任何地方使用该脚本）：
+
+**参数**
+
+- `--data (list[str])`: 设置在 VLMEvalKit 中支持的数据集名称（可以在代码库首页的 README 中找到支持的数据集列表）
+- `--model (list[str])`: 设置在 VLMEvalKit 中支持的 VLM 名称（在 `vlmeval/config.py` 中的 `supported_VLM` 中定义）
+- `--mode (str, 默认值为 'all', 可选值为 ['all', 'infer'])`：当 mode 设置为 "all" 时，将执行推理和评估；当设置为 "infer" 时，只执行推理
+- `--api-nproc (int, 默认值为 4)`: 调用 API 的线程数
+- `--work-dir (str, default to '.')`: 存放测试结果的目录
+
+**用于评测图像多模态评测集的命令**
+
+你可以使用 `python` 或 `torchrun` 来运行脚本:
+
+```bash
+# 使用 `python` 运行时，只实例化一个 VLM，并且它可能使用多个 GPU。
+# 这推荐用于评估参数量非常大的 VLMs（如 IDEFICS-80B-Instruct）。
+
+# 在 MMBench_DEV_EN、MME 和 SEEDBench_IMG 上使用 IDEFICS-80B-Instruct 进行推理和评估
+python run.py --data MMBench_DEV_EN MME SEEDBench_IMG --model idefics_80b_instruct --verbose
+# 在 MMBench_DEV_EN、MME 和 SEEDBench_IMG 上使用 IDEFICS-80B-Instruct 仅进行推理
+python run.py --data MMBench_DEV_EN MME SEEDBench_IMG --model idefics_80b_instruct --verbose --mode infer
+
+# 使用 `torchrun` 运行时，每个 GPU 上实例化一个 VLM 实例。这可以加快推理速度。
+# 但是，这仅适用于消耗少量 GPU 内存的 VLMs。
+
+# 在 MMBench_DEV_EN、MME 和 SEEDBench_IMG 上使用 IDEFICS-9B-Instruct、Qwen-VL-Chat、mPLUG-Owl2。在具有 8 个 GPU 的节点上进行推理和评估。
+torchrun --nproc-per-node=8 run.py --data MMBench_DEV_EN MME SEEDBench_IMG --model idefics_80b_instruct qwen_chat mPLUG-Owl2 --verbose
+# 在 MME 上使用 Qwen-VL-Chat。在具有 2 个 GPU 的节点上进行推理和评估。
+torchrun --nproc-per-node=2 run.py --data MME --model qwen_chat --verbose
+```
+
+**用于评测视频多模态评测集的命令**
+
+```bash
+# 使用 `python` 运行时，只实例化一个 VLM，并且它可能使用多个 GPU。
+# 这推荐用于评估参数量非常大的 VLMs（如 IDEFICS-80B-Instruct）。
+
+# 在 MMBench-Video 上评测 IDEFCIS2-8B, 视频采样 8 帧作为输入，不采用 pack 模式评测. MMBench_Video_8frame_nopack 是一个定义在 `vlmeval/dataset/video_dataset_config.py` 的数据集设定.
+torchrun --nproc-per-node=8 run.py --data MMBench_Video_8frame_nopack --model idefics2_8
+# 在 MMBench-Video 上评测 GPT-4o (API 模型), 视频采样每秒一帧作为输入，采用 pack 模式评测
+python run.py --data MMBench_Video_1fps_pack --model GPT4o
+```
+
+评估结果将作为日志打印出来。此外，**结果文件**也会在目录 `$YOUR_WORKING_DIRECTORY/{model_name}` 中生成。以 `.csv` 结尾的文件包含评估的指标。
+### 常见问题
+#### 构建输入prompt：`build_prompt()`函数
+如果您在评测某个benchmark时，发现模型输出的结果与预期不符，可能是因为您使用的模型没有正确构建输入prompt。
+
+在VLMEvalkit中，每个`dataset`类都包含一个名为`build_prompt()`的函数，用于构建输入问题的格式。不同的benchmark可以选择自定义`build_prompt()`函数，也可以使用默认的实现。
+
+例如，在处理默认的[多选题/Multi-Choice QA]([vlmeval/dataset/image_mcq.py](https://github.com/open-compass/VLMEvalKit/blob/43af13e052de6805a8b08cd04aed5e0d74f82ff5/vlmeval/dataset/image_mcq.py#L164))时，`ImageMCQDataset.build_prompt()`类会将`hint`、`question`、`options`等元素（若数据集中包含）组合成一个完整的问题格式，如下所示：
+```
+HINT
+QUESTION
+Options:
+A. Option A
+B. Option B
+···
+Please select the correct answer from the options above.
+```
+
+此外，由于不同模型对评测的需求可能有所不同，VLMEvalkit也支持在模型层面自定义对不同benchmark构建prompt的方法，即`model.build_prompt()`，具体示例可以参考[InternVL](https://github.com/open-compass/VLMEvalKit/blob/43af13e052de6805a8b08cd04aed5e0d74f82ff5/vlmeval/vlm/internvl_chat.py#L324)。
+
+**注意：当同时定义了`model.build_prompt()`以及`dataset.build_prompt()`时，`model.build_prompt()`将优先于`dataset.build_prompt()`，即前者会覆盖后者。**
+
+由于部分模型（如Qwen2VL，InternVL等）对于不同类型的benchmark定义了广泛的prompt构建方法，为了更灵活地适应不同的benchmark，VLMEvalkit支持在模型中自定义`model.use_custom_prompt()`函数。通过添加或者修改`use_custom_prompt()`函数，您可以决定对于哪些benchmark使用模型自定义的`use_custom_prompt()`方法，示例如下：
+```
+def use_custom_prompt(self, dataset: str) -> bool:
+    from vlmeval.dataset import DATASET_TYPE, DATASET_MODALITY
+    dataset_type = DATASET_TYPE(dataset, default=None)
+    if not self._use_custom_prompt:
+        return False
+    if listinstr(['MMVet'], dataset):
+        return True
+    if dataset_type == 'MCQ':
+        return True
+    if DATASET_MODALITY(dataset) == 'VIDEO':
+        return False
+    return False
+```
+仅当`use_custom_prompt()`函数返回`True`时，VLMEvalkit才会对当前benchmark调用模型的`build_prompt()`函数。
+通过这种方式，您可以根据具体需求灵活地控制哪些benchmark使用模型自定义的prompt构建逻辑，从而更好地适配不同模型和任务的需求。
+
+#### 模型切分
+
+目前 VLMEvalKit 的启动方式自动支持同机上进程间 GPU 资源的划分与模型切分。该功能在推理后端为 `lmdeploy` 或 `transformers` 时被支持，具体行为如下：
+
+- 基于 `python` 命令启动时，模型默认分配到所有可用的 GPU 上，如想指定使用哪些 GPU，可以使用 `CUDA_VISIBLE_DEVICES` 环境变量。
+- 基于 `torchrun` 命令启动时，每个模型实例会被分配到 `N_GPU // N_PROC` 个 GPU 上，`N_PROC` 为 torchrun 命令中的 `--nproc-per-node` 参数所指定的进程数。`N_GPU` 的取值为：
+    - 如 `CUDA_VISIBLE_DEVICES` 环境变量未设置，`N_GPU` 为全部可用 GPU 数量。
+    - 如 `CUDA_VISIBLE_DEVICES` 环境变量被设置，`N_GPU` 为 `CUDA_VISIBLE_DEVICES` 环境变量所指定的 GPU 数量，并且，仅有指定的 GPU 会被利用。
+
+下面提供了，在一台配备 8 块 GPU 的机器上运行评测任务的具体示例：
+```bash
+# <!-- 起两个模型实例数据并行，每个实例用 4 GPU -->
+torchrun --nproc-per-node=2 run.py --data MMBench_DEV_EN --model InternVL3-78B
+# <!-- 起一个模型实例，每个实例用 8 GPU -->
+python run.py --data MMBench_DEV_EN --model InternVL3-78B
+# <!-- 起三个模型实例，每个实例用 2 GPU，0 号、7 号 GPU 未被使用 -->
+CUDA_VISIBLE_DEVICES=1,2,3,4,5,6 torchrun --nproc-per-node=3 run.py --data MMBench_DEV_EN --model InternVL3-38B
+```
+
+注：此方式不支持 `vllm` 后端，基于 `vllm` 后端起评测任务时，请用 `python` 命令启动，默认调用所有可见的 GPU。
+
+#### 性能差距
+在不同的运行环境中，模型的性能表现可能会有所差异。因此，在评估过程中，您可能会发现自己的评测结果与VLMEvalKit官方榜单上的结果存在差距。这种差异可能与`transformers`, `cuda`, `torch`等版本的变化有关。
+
+此外，对于异常的表现，我们建议您优先查看运行完成后的本地生成记录`{model}_{dataset}.xlsx`或者评估记录`{model}_{dataset}_{judge_model}.xlsx`，这可能会帮助��更好地理解评估结果并发现问题。
+
+
+
+### 部署本地语言模型作为评判 / 选择提取器
+上述默认设置使用 OpenAI 的 GPT 作为评判 LLM。你也可以使用 [LMDeploy](https://github.com/InternLM/lmdeploy) 部署本地评判 LLM。
+
+首先进行安装:
+```
+pip install lmdeploy openai
+```
+
+然后可以通过一行代码部署本地评判 LLM。LMDeploy 将自动从 Huggingface 下载模型。假设我们使用 internlm2-chat-1_8b 作为评判，端口为 23333，密钥为 sk-123456（密钥必须以 "sk-" 开头，后跟任意数字）：
+```
+lmdeploy serve api_server internlm/internlm2-chat-1_8b --server-port 23333
+```
+
+使用以下 Python 代码获取由 LMDeploy 注册的模型名称：
+```
+from openai import OpenAI
+client = OpenAI(
+    api_key='sk-123456',
+    base_url="http://0.0.0.0:23333/v1"
+)
+model_name = client.models.list().data[0].id
+```
+
+配置对应环境变量，以告诉 VLMEvalKit 如何使用本地评判 LLM。正如上面提到的，也可以在  `$VLMEvalKit/.env` 文件中设置：
+```
+OPENAI_API_KEY=sk-123456
+OPENAI_API_BASE=http://0.0.0.0:23333/v1/chat/completions
+LOCAL_LLM=<model_name you get>
+```
+
+最后，你可以运行第2步中的命令，使用本地评判 LLM 来评估你的 VLM。
+
+**请注意：**
+
+- 如果你希望将评判 LLM 部署在单独的一个 GPU 上，并且由于 GPU 内存有限而希望在其他 GPU 上评估你的 VLM，可以使用 `CUDA_VISIBLE_DEVICES=x` 这样的方法，例如：
+```
+CUDA_VISIBLE_DEVICES=0 lmdeploy serve api_server internlm/internlm2-chat-1_8b --server-port 23333
+CUDA_VISIBLE_DEVICES=1,2,3 torchrun --nproc-per-node=3 run.py --data HallusionBench  --model qwen_chat --verbose
+```
+- 如果本地评判 LLM 在遵循指令方面不够好，评估过程可能会失败。请通过 issues 报告此类失败情况。
+- 可以以不同的方式部署评判 LLM，例如使用私有 LLM（而非来自 HuggingFace）或使用量化 LLM。请参考 [LMDeploy doc](https://lmdeploy.readthedocs.io/en/latest/serving/api_server.html) 文档。也可以使用其他支持 OpenAI API 框架的方法。
