aguvis-stage1-mixture

# aguvis-stage1-mixture

本数据集来源于 HuggingFace 上的 `smolagents/aguvis-stage-1` ，使用随机种子 42 对合并后的数据集进行shuffle。合并数据集加载顺序如下dataset_mixture_phase_1所示。随后，按约 12GB 每个 shard 的目标大小切分为 Parquet 分片（内部默认单文件大小约 450MB，按文件数自动聚合成若干 `shard_xxx` 目录），最终形成 `shard_000` ~ `shard_018` 的子集。

```python
dataset_mixture_phase_1 = [
{"id": "smolagents/aguvis-stage-1", "config": "guienv", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "omniact", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "ricoig16k", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "ricosca", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "seeclick", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "ui_refexp", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "webui350k", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "widget_captioning", "split": "train", "columns": ["images", "texts"]},
]
```

#### 使用示例

```python
from modelscope.msdatasets import MsDataset

# 加载整个数据集
ds = MsDataset.load('scallioncake/aguvis-stage1-mixture')

# 加载指定的 shard
ds = MsDataset.load('scallioncake/aguvis-stage1-mixture', subset_name='shard_000')
ds = MsDataset.load('scallioncake/aguvis-stage1-mixture', subset_name='shard_001')
# ... 可以加载任意 shard_xxx (shard_000 到 shard_018)
```

# aguvis-stage1-mixture

本数据集源自HuggingFace平台上的`smolagents/aguvis-stage-1`，以随机种子42对合并后的数据集执行打乱（shuffle）操作。合并数据集的加载顺序如下`dataset_mixture_phase_1`所示：
python
dataset_mixture_phase_1 = [
{"id": "smolagents/aguvis-stage-1", "config": "guienv", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "omniact", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "ricoig16k", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "ricosca", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "seeclick", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "ui_refexp", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "webui350k", "split": "train", "columns": ["images", "texts"]},
{"id": "smolagents/aguvis-stage-1", "config": "widget_captioning", "split": "train", "columns": ["images", "texts"]},
]

随后，以每个分片（shard）目标大小约12GB为基准，将数据集切分为Parquet格式分片；其内部默认单文件大小约450MB，会根据文件数量自动聚合为若干`shard_xxx`目录，最终生成`shard_000`至`shard_018`的子集。

#### 使用示例
python
from modelscope.msdatasets import MsDataset

# 加载完整数据集
ds = MsDataset.load('scallioncake/aguvis-stage1-mixture')

# 加载指定分片（shard）
ds = MsDataset.load('scallioncake/aguvis-stage1-mixture', subset_name='shard_000')
ds = MsDataset.load('scallioncake/aguvis-stage1-mixture', subset_name='shard_001')
# ... 可加载任意`shard_xxx`分片（覆盖shard_000至shard_018）
