We followed the dataset preparation process of DeCLIP here.

1. First, Download DeCLIP's YFCC15M label file 'yfcc15m_clean_open_data.json' at Google Driver.

2. Extract the URL from the JSON file and split it into several URL list files for download using split_download_task.py.

3. Crawl the image by the URL dirctely using auto_download.bat (Here, we use Wget, you may need to install that). The bat file is for Windows, and you may need to rewrite a shell file if using Linux. Or, simply download from the links below!

   • You can stop the process and start over afterward if something is wrong. Wget will skip the downloaded files and clean log files.
   • The error will be recorded in log files. Before re-start the download, it is recommended to run clean_err_file_from_logs.py to filter and delete the wrong files.

4. Check the downloaded images using check_images.py.
