| # Data Preparation for HACS | |
| ## Download Annotations | |
| You can download the annotation by | |
| ```bash | |
| bash download_annotation.sh | |
| ``` | |
| The annotation should be in `data/hacs-1.1.1/annotations/`. | |
| ## Download Pre-extracted Features | |
| Please put the downloaded feature under the path: `data/hacs-1.1.1/features/`. | |
| We provide the following pre-extracted features for HACS: | |
