</div>

Check the **[XAMI model](https://github.com/ESA-Datalabs/XAMI-model)** and the **[XAMI dataset](https://huggingface.co/datasets/iulia-elisa/XAMI-dataset)** on Github. 

# Downloading the dataset

- using a python script

```python
from huggingface_hub import hf_hub_download

dataset_name = 'xami_dataset' # the dataset name of Huggingface
images_dir = '.' # the output directory of the dataset images

hf_hub_download(
    repo_id="iulia-elisa/XAMI-dataset", # the Huggingface repo ID
    repo_type='dataset', 
    filename=dataset_name+'.zip', 
    local_dir=images_dir
);

# Unzip file
!unzip -q "xami_dataset.zip" -d 'path/to/dest'
```

Or you can simply download only the dataset zip file from HuggingFace using a CLI command:

```bash
DEST_DIR='/path/to/local/dataset/dir'

huggingface-cli download iulia-elisa/XAMI-dataset xami_dataset.zip --repo-type dataset --local-dir "$DEST_DIR" && unzip "$DEST_DIR/xami_dataset.zip" -d "$DEST_DIR" && rm "$DEST_DIR/xami_dataset.zip"
```
