权重下载及转换

1. 权重下载

从Huggingface库下载对应的模型权重:

将下载的模型权重保存到本地的ckpt/hf_path/Qwen3-VL-*B-Instruct目录下。(*表示对应的尺寸)


数据集准备及处理

1. 数据集下载(以coco2017数据集为例)

(1)用户需要自行下载COCO2017数据集COCO2017,并解压到项目目录下的./data/COCO2017文件夹中。

(2)获取图片数据集的描述文件(LLaVA-Instruct-150K),下载至./data/路径下。

(3)运行数据转换脚本python examples/qwen2vl/llava_instruct_2_mllm_demo_format.py,转换后参考数据目录结构如下:

$playground
├── data
    ├── COCO2017
        ├── train2017

    ├── llava_instruct_150k.json
    ├── mllm_format_llava_instruct_data.json
    ...

当前支持读取多个以,(注意不要加空格)分隔的数据集,配置方式为data.json中 dataset_param->basic_parameters->dataset 从"./data/mllm_format_llava_instruct_data.json"修改为"./data/mllm_format_llava_instruct_data.json,./data/mllm_format_llava_instruct_data2.json"

同时注意data.jsondataset_param->basic_parameters->max_samples的配置,会限制数据只读max_samples条,这样可以快速验证功能。如果正式训练时,可以把该参数去掉则读取全部的数据。

2.纯文本或有图无图混合训练数据(以LLaVA-Instruct-150K为例)

现在本框架已经支持纯文本/混合数据(有图像和无图像数据混合训练)。

在数据构造时,对于包含图片的数据,需要保留image这个键值。

{
  "id": your_id,
  "image": your_image_path,
  "conversations": [
      {"from": "human", "value": your_query},
      {"from": "gpt", "value": your_response},
  ],
}

在数据构造时,对于纯文本数据,可以去除image这个键值。

{
  "id": your_id,
  "conversations": [
      {"from": "human", "value": your_query},
      {"from": "gpt", "value": your_response},
  ],
}

微调

1. 准备工作

配置脚本前需要完成前置准备工作,包括:环境安装权重下载及转换数据集准备及处理,详情可查看对应章节。

2. 配置参数

【数据目录配置】

根据实际情况修改data.json中的数据集路径,包括model_name_or_pathdataset_dirdataset等字段。

示例:如果数据及其对应的json都在/home/user/data/目录下,其中json目录为/home/user/data/video_data_path.json,此时配置如下: dataset_dir配置为/home/user/data/; dataset配置为./data/video_data_path.json 注意此时dataset需要配置为相对路径

以Qwen3VL-xxB为例,data.json进行以下修改,注意model_name_or_path的权重路径为转换前的权重路径。

注意cache_dir在多机上不要配置同一个挂载目录避免写入同一个文件导致冲突

{
    "dataset_param": {
        "dataset_type": "huggingface",
        "preprocess_parameters": {
            "model_name_or_path": "./ckpt/hf_path/Qwen3-VL-xxB-Instruct",
            ...
        },
        "basic_parameters": {
            ...
            "dataset_dir": "./data",
            "dataset": "./data/mllm_format_llava_instruct_data.json",
            "cache_dir": "./data/cache_dir",
            ...
        },
        ...
    },
    ...
}

如果需要加载大批量数据,可使用流式加载,修改data.json中的sampler_type字段,增加streaming字段。(注意:使用流式加载后当前仅支持num_workers=0,单进程处理数据,会有性能波动,并且不支持断点续训功能。)

{
    "dataset_param": {
        ...
        "basic_parameters": {
            ...
            "streaming": true
            ...
        },
        ...
    },
    "dataloader_param": {
        ...
        "sampler_type": "stateful_distributed_sampler",
        ...
    }
}

【模型保存加载及日志信息配置】

根据实际情况配置examples/qwen3vl/finetune_qwen3vl.sh的参数,包括加载、保存路径以及保存间隔--save-interval(注意:分布式优化器保存文件较大耗时较长,请谨慎设置保存间隔)

...
# 断点续训权重加载路径
LOAD_PATH="./ckpt/save_dir/Qwen3-VL-xxB-Instruct"
# 保存路径
SAVE_PATH="save_dir"
...
GPT_ARGS="
    ...
    --no-load-optim \  # 不加载优化器状态,若需加载请移除
    --no-load-rng \  # 不加载随机数状态,若需加载请移除
    --no-save-optim \  # 不保存优化器状态,若需保存请移除
    --no-save-rng \  # 不保存随机数状态,若需保存请移除
    ...
"
...
OUTPUT_ARGS="
    --log-interval 1 \  # 日志间隔
    --save-interval 5000 \  # 保存间隔
    ...
"

根据实际情况配置examples/qwen3vl/model.json中的init_from_hf_path参数,该参数表示初始权重的加载路径。

【单机运行配置】

配置examples/qwen3vl/finetune_qwen3vl.sh参数如下

# 根据实际情况修改 ascend-toolkit 路径
source /usr/local/Ascend/ascend-toolkit/set_env.sh
NPUS_PER_NODE=8
MASTER_ADDR=localhost
MASTER_PORT=29501
NNODES=1
NODE_RANK=0
WORLD_SIZE=$(($NPUS_PER_NODE * $NNODES))

3. 启动微调

以Qwen3VL-xxB为例,启动微调训练任务。

bash examples/qwen3vl/finetune_qwen3vl.sh

4. 启动推理

训练完成之后,以Qwen3VL-xxB为例,将保存在save_dir目录下的权重转换成huggingface格式

python checkpoint/common/merge_dcp_to_hf.py \
  --load-dir save_dir/iter_000xx/ \
  --save-dir save_dir/iter_000xx_hf/ \
  --model-assets-dir ./ckpt/Qwen3-VL-xxB-Instruct \
  --prefix model.

其中,iter_000xx表示保存的第xx步的权重,--save_dir表示转换后的权重保存路径,--model_assets_dir原始huggingface权重的路径。

完成权重转换之后,即可使用transformers库进行推理。
