## Load Dataset without Extracting
You don’t need to unpack the .tar archives, use WebDataset support in 🤗datasets instead:

```
from datasets import load_dataset
import glob

data_files = glob.glob("/your/data/path/*.tar")
train_dataset = load_dataset(
"webdataset",
data_files=data_files,
cache_dir="/your/hf/cache",
split="train",
num_proc=128
)
```

Feel free to comment on it when you have any issues.

### 下载
python

## 无需解压加载数据集
无需对.tar归档文件进行解压，可直接使用🤗datasets库中的WebDataset支持功能进行加载：

from datasets import load_dataset
import glob

data_files = glob.glob("/your/data/path/*.tar")
train_dataset = load_dataset(
"webdataset",
data_files=data_files,
cache_dir="/your/hf/cache",
split="train",
num_proc=128
)
