Video-DiG 训练数据 (v5 final)
本数据集是 Video-DiG: Video Difference Grounding with Reinforcement Learning 项目最终实际使用的训练数据（v5），用于以 GRPO 训练 Qwen3-VL 做双视频差异定位 / 识别。
⚠️ 私有仓库，仅授权使用。
规模
9,433 条，全部为 A/B 双视频对比 任务：
- mcq（选择题）：5,333
- grounding（定位）：4,100
共引用 11,216 个视频（A/B 成对）。子集 × 任务分布详见 训练数据说明.md。

⚠️ 视频路径已改为相对路径
原始 swift_train_data_v5.json 中 videos 为本地绝对路径，上传时已统一改写为仓库内相对路径 videos/<文件名>。使用时把仓库根目录作为前缀拼接：
import json, os
from huggingface_hub import snapshot_download
root = snapshot_download("yuyuang/Video-DiG-Data", repo_type="dataset")
data = json.load(open(os.path.join(root, "swift_train_data_v5.json")))
e = data[0]
vids = [os.path.join(root, v) for v in e["videos"]] # 拼成可用绝对路径
训练入口与完整
