赛事说明：https://tianchi.aliyun.com/competition/entrance/532251/introduction?spm=a2c22.12281925.0.0.2f307137p8qZmp
学习平台：https://linklearner.com/home

第一天

1.报名赛道学习赛事 https://tianchi.aliyun.com/competition/entrance/532251
2.尝试跑通baseline并打卡 https://linklearner.com/activity/14/13/27

详细描述：
Better Synth 是一项以数据为中心的挑战赛，考察如何合成与清洗图文数据以在多模态大模型上取得更优的图片理解能力。
本次比赛基于 Mini-Gemini 模型进行训练，只关注于预训练（模态间对齐）阶段的数据合成与清洗，指令微调阶段为固定数据集。为了选手更高效地迭代数据合成方案，本次比赛选用 MGM-2B 规模的模型作为比赛模型。
主办方提供候选种子数据集，要求参赛者基于种子数据集进行数据合成与清洗，产出一份基于种子数据集的更高质量、更多样性的数据集，并在给定计算约束下进行训练。主办方提供开发套件，要求参赛者在统一的框架和参数设置下进行模型训练和任务评测，公平对比数据导致的性能差异。数据集产出流程中必须包含“合成”的过程，未包含的方案会被认为是无效方案。

环境安装

使用阿里云创建 DSW实例，可以试用3个月5000算力。然后在 魔搭社区 -> 我的Notebook -> 个人云账号授权实例 -> PAI-DSW 创建实例。
镜像链接：dsw-registry-vpc.cn-hangzhou.cr.aliyuncs.com/pai-training-algorithm/data-juicer-better-synth:0.0.1

若不是镜像链接的则需要安装环境：

SCRIPT_DIR=$(cd "$(dirname "$0")" && pwd)# for data-juicer
echo "[1] Installing toolkit/data-juicer"
cd ${SCRIPT_DIR}/toolkit
git clone https://github.com/modelscope/data-juicer.git
cd data-juicer
pip install ".[all]"# for MGM training
echo "[2] Installing toolkit/training"
cd ${SCRIPT_DIR}/toolkit/training
pip install -e .
pip install flash-attn --no-build-isolationecho "Done"

baseline文件解析

  1. input -> pretrain_stage_1_10k：包含10k的图像文字数据对，images中是图像，mgm-pretrain-stage.json中是图像和文字对匹配
  2. models 中存放 BLIP2 模型
  3. toolkit:
    • train_mgm_2b_stage_1.sh 训练脚本
    • eval 评测数据集
    • training 训练数据集和模型
      • data: eval、finetune
      • model_zoo: LLM(Gemma)、Openai(CLIP)
  4. output：
    • image_caption_output / res_10k.jsonl
    • eval_result
    • training_dirs：pretrain_dir、finetune_dir

跑baseline

  1. 下载baseline代码： git clone https://www.modelscope.cn/datasets/Datawhale/better_synth_challenge_baseline.git
    安装
apt update & apt install axel zip file
pip install modelscope

其中 axel 可以用来加速下载。

  1. 下载模型和数据
cd better_synth_challenge_baseline
bash download.sh  ###大概需要50分钟

注意：
速度很慢可以 ctl+C 再重新下，每次会断点续传。
看到有 tar.gz.st 的就是还没下好，需要继续下载。
每次下载完毕后会进行解压缩，此时千万别看着卡住了就 ctl+c ，不然会没有完全解压缩出现问题。

  1. 下载BLIP模型，用来生成图片的字幕
### 下载BLIP模型，大概需要20分钟
from modelscope import snapshot_downloadmodel_dir = snapshot_download('goldsj/blip2-opt-2.7b', cache_dir='/mnt/workspace/better_synth_challenge_baseline/models', revision='master')

使用 data-juice 对数据进行处理：使用BLIP2对图片进行字幕生成
dj-process --config solution/image_captioning.yaml


dataset_path: /mnt/workspace/better_synth_challenge_baseline/input/pretrain_stage_1_10k/mgm_pretrain_stage_1_10k.jsonl
export_path: /mnt/workspace/better_synth_challenge_baseline/output/image_captioning_output/res_10k.jsonlnp: 1
process:- image_captioning_mapper:hf_img2seq: '/mnt/workspace/better_synth_challenge_baseline/models/goldsj/blip2-opt-2___7b'  # You can replace this path to a local downloaded HF modelkeep_original_sample: false  # we only need the recaptioned captions

  1. 处理完数据后，执行模型的训练和推理
    需要修改实例配置，在 阿里云平台PAI -> 交互式建模(DSW) -> 变更实例配置，修改为32G显存及以上的GPU规格 (注意二阶段finetune需要至少32G)
    在这里插入图片描述

然后执行

cd toolkit
git clone https://github.com/modelscope/data-juicer.git
bash train_mgm_2b_stage_1.sh   ### 大概需要3小时

train_mgm_2b_stage_1.sh：这里会执行一个pretrain，二阶段 finetune，然后进行评测
