# LOTUSDIS

## Dataset Description

## How to use

You can easily load the dataset using the 🤗 `datasets` library. The dataset can be loaded and prepared with a single line of Python code:
```python
from datasets import load_dataset
lotus_dis = load_dataset("nectec/LOTUSDIS", split="train")
```

To iterate through the dataset without downloading it entirely, you can use streaming mode:
```python
from datasets import load_dataset
lotus_dis = load_dataset("nectec/LOTUSDIS", split="train", streaming=True)
print(next(iter(lotus_dis)))
```

Learn more about how to load and prepare audio datasets in the [Hugging Face Audio Datasets tutorial](https://huggingface.co/blog/audio-datasets).
