Many of the MME landmark images are not available for download

[xuanmingcui]

Hello, thank you for the wonderful work and the dataset!

I was trying to download the landmark images by running MME_Benchmark_release_version/landmark/images/download_landmark.py. But only ~35 images were successfully downloaded, while others having error: Failed to download the URL file.

Is there other alternative sources for downloading these images? Or did I do anything incorrectly.

Thanks for the help in advance :)

I ended up slightly modifying the given download_landmark.py file, to tackle this issue, sharing here if it benefits others

import os
import argparse
import pandas as pd
import urllib.request
from tqdm import tqdm
import requests
import urllib.parse

def download_url_images(csv_file, output_folder,extension='.jpg'):
    df = pd.read_csv(csv_file)
    ids = df['id'].tolist()
    urls = df['url'].tolist()
    # for i, url in tqdm(enumerate(urls), total=len(urls), desc='Downloading'):
    for i, url in enumerate(urls):
        if not os.path.exists(output_folder):
            os.makedirs(output_folder)
        save_path = output_folder + str(ids[i]) + extension
        if not os.path.isfile(save_path):
            try:
                urllib.request.urlretrieve(url, save_path,)
            except:
                try:
                    url = urllib.parse.unquote(url)
                    urllib.request.urlretrieve(url, save_path,)
                except:
                    print("Failed to download the URL file:", url)
                    print("Save_path:", save_path)

if __name__ == '__main__':

    parser = argparse.ArgumentParser(description='Download images from URL in a CSV file.')
    parser.add_argument('--csv_file', help='Path to the CSV file')
    parser.add_argument('--output_folder', help='Output folder to save downloaded images')
    parser.add_argument('--extension', default='.jpg', help='File extension for downloaded images (default: .jpg)')
    args = parser.parse_args()

    # ide usage
    args.csv_file = './landmark200.csv'
    args.output_folder = './'
    args.extension = '.jpg'

    download_url_images(args.csv_file, args.output_folder, args.extension)
