+# Multi-modality Evaluation
+
+We support several multi-modality datasets, such as [MMBench](https://opencompass.org.cn/MMBench), [SEED-Bench](https://github.com/AILab-CVC/SEED-Bench) to evaluate multi-modality models. Before starting, please make sure you have downloaded the evaluation datasets following the official instruction.
+
+## Start Evaluation
+
+Before evaluation, you could modify `tasks.py` or create a new file like `tasks.py` to evaluate your own model.
+
+Generally to run the evaluation, we use command below.
+
+### Slurm
+
+```sh
+cd $root
+python run.py configs/multimodal/tasks.py --mm-eval --slurm -p $PARTITION
+```
+
+### PyTorch
+
+```sh
+cd $root
+python run.py configs/multimodal/tasks.py --mm-eval
+```
+
+## Configuration File
+
+We adapt the new config format of [MMEngine](https://mmengine.readthedocs.io/en/latest/advanced_tutorials/config.html#a-pure-python-style-configuration-file-beta).
+
+### Task File
+
+Here is the example config of `configs/multimodal/tasks.py`.
+
+```python
+from mmengine.config import read_base
+
+with read_base():
+    from .minigpt_4.minigpt_4_7b_mmbench import (minigpt_4_mmbench_dataloader,
+                                                 minigpt_4_mmbench_evaluator,
+                                                 minigpt_4_mmbench_load_from,
+                                                 minigpt_4_mmbench_model)
+
+models = [minigpt_4_mmbench_model]
+datasets = [minigpt_4_mmbench_dataloader]
+evaluators = [minigpt_4_mmbench_evaluator]
+load_froms = [minigpt_4_mmbench_load_from]
+
+# set the platform and resources
+num_gpus = 8
+num_procs = 8
+launcher = 'pytorch'
+```
+
+### Details of Task
+
+Here is an example of MiniGPT-4 with MMBench and we provide some comments for
+users to understand the meaning of the keys in config.
+
+```python
+from opencompass.multimodal.models.minigpt_4 import (

+# 多模态评测
+
+我们支持了多个多模态数据集，例如 [MMBench](https://opencompass.org.cn/MMBench)，[SEED-Bench](https://github.com/AILab-CVC/SEED-Bench)，来对多模态模型进行评测。在开始评测之前，请确保您已经按照官方教程下载了评测数据集。
+
+## 开始评测
+
+在评测前，您需要先修改 `tasks.py` 或者创建一个类似的新文件 `tasks_your_model.py` 来对您的模型进行评测。
+
+一般来说我们使用下列命令启动评测。
+
+### Slurm
+
+```sh
+cd $root
+python run.py configs/multimodal/tasks.py --mm-eval --slurm -p $PARTITION
+```
+
+### PyTorch
+
+```sh
+cd $root
+python run.py configs/multimodal/tasks.py --mm-eval
+```
+
+## 配置文件
+
+We adapt the new config format of [MMEngine](https://mmengine.readthedocs.io/en/latest/advanced_tutorials/config.html#a-pure-python-style-configuration-file-beta).
+
+### 任务文件
+
+这是 `configs/multimodal/tasks.py` 的示例。
+
+```python
+from mmengine.config import read_base
+
+with read_base():
+    from .minigpt_4.minigpt_4_7b_mmbench import (minigpt_4_mmbench_dataloader,

+                                                 minigpt_4_mmbench_model)
