Qwen2-Audio的最佳实践可以查看: #1653

目录

环境准备

pip install 'ms-swift[llm]' -U

推理

推理qwen-audio-chat:

# Experimental environment: A10, 3090, V100...
# 21GB GPU memory
CUDA_VISIBLE_DEVICES=0 swift infer --model_type qwen-audio-chat

输出: (支持传入本地路径或URL)

微调

多模态大模型微调通常使用自定义数据集进行微调. 这里展示可直接运行的demo:

LoRA微调:

# Experimental environment: A10, 3090, V100...
# 22GB GPU memory
CUDA_VISIBLE_DEVICES=0 swift sft \
    --model_type qwen-audio-chat \
    --dataset aishell1-mini-zh \

全参数微调:

# MP
# Experimental environment: 2 * A100
# 2 * 50 GPU memory
CUDA_VISIBLE_DEVICES=0,1 swift sft \
    --model_type qwen-audio-chat \
    --dataset aishell1-mini-zh \
    --sft_type full \

# ZeRO2
# Experimental environment: 4 * A100
# 4 * 80 GPU memory
NPROC_PER_NODE=4 CUDA_VISIBLE_DEVICES=0,1,2,3 swift sft \
    --model_type qwen-audio-chat \
    --dataset aishell1-mini-zh \
    --sft_type full \
    --use_flash_attn true \
    --deepspeed default-zero2

自定义数据集支持json, jsonl样式, 以下是自定义数据集的例子:

(支持多轮对话, 支持每轮对话含多段语音或不含语音, 支持传入本地路径或URL)

[
    {"conversations": [
        {"from": "user", "value": "<audio>audio_path</audio>11111"},
        {"from": "assistant", "value": "22222"}
    ]},
    {"conversations": [
        {"from": "user", "value": "<audio>audio_path</audio><audio>audio_path2</audio><audio>audio_path3</audio>aaaaa"},
        {"from": "assistant", "value": "bbbbb"},
        {"from": "user", "value": "<audio>audio_path</audio>ccccc"},
        {"from": "assistant", "value": "ddddd"}
    ]},
    {"conversations": [
        {"from": "user", "value": "AAAAA"},
        {"from": "assistant", "value": "BBBBB"},
        {"from": "user", "value": "CCCCC"},
        {"from": "assistant", "value": "DDDDD"}
    ]}
]

微调后推理

直接推理:

CUDA_VISIBLE_DEVICES=0 swift infer \
    --ckpt_dir output/qwen-audio-chat/vx-xxx/checkpoint-xxx \
    --load_dataset_config true \

merge-lora并推理:

CUDA_VISIBLE_DEVICES=0 swift export \
    --ckpt_dir output/qwen-audio-chat/vx-xxx/checkpoint-xxx \
    --merge_lora true

CUDA_VISIBLE_DEVICES=0 swift infer \
    --ckpt_dir output/qwen-audio-chat/vx-xxx/checkpoint-xxx-merged \
    --load_dataset_config true
