# QuantaAlpha Qlib CSI300 Dataset

[**Project Page**](https://quantaalpha.github.io/) | [**Paper**](https://huggingface.co/papers/2602.07085) | [**GitHub**](https://github.com/QuantaAlpha/QuantaAlpha)

Qlib market data and pre-computed HDF5 files for QuantaAlpha factor mining (A-share, CSI 300).

## Dataset description

| Filename       | Description                                      |
| -------------- | ------------------------------------------------- |
| daily_pv.h5    | Adjusted daily price and volume data.            |
| daily_pv_debug.h5 | Debug subset (smaller) of price-volume data. |

## How to load from Hugging Face

```python
from huggingface_hub import hf_hub_download
import pandas as pd

# Download a file from this dataset
path = hf_hub_download(
    repo_id="QuantaAlpha/qlib_csi300",
    filename="daily_pv.h5",
    repo_type="dataset"
)
df = pd.read_hdf(path, key="data")
```

**Note:** The key is always `"data"` for all HDF5 files in this dataset.

## How to read the files locally

If you have already downloaded the files:

```python
import pandas as pd
df = pd.read_hdf("daily_pv.h5", key="data")
```
