So i was trying to follow this tutorial https://www.youtube.com/watch?v=Lg4T9iJkwhE&t=155s to achieve image detection with YOLO.

and when trying to run this code to auto download images of cell phones but it didn't work 

import os
import urllib.request as ulib
from  bs4 import BeautifulSoup as Soup
import json

url_a = 'https://www.google.com/search?ei=1m7NWePfFYaGmQG51q7IBg&hl=en&q={}'
url_b = '\&tbm=isch&ved=0ahUKEwjjovnD7sjWAhUGQyYKHTmrC2kQuT0I7gEoAQ&start={}'
url_c = '\&yv=2&vet=10ahUKEwjjovnD7sjWAhUGQyYKHTmrC2kQuT0I7gEoAQ.1m7NWePfFYaGmQG51q7IBg'
url_d = '\.i&ijn=1&asearch=ichunk&async=_id:rg_s,_pms:s'
url_base = ''.join((url_a, url_b, url_c, url_d))

headers = {'User-Agent': 'Chrome/41.0.2228.0 Safari/537.36'}


def get_links(search_name):
    search_name = search_name.replace(' ', '+')
    url = url_base.format(search_name, 0)
    request = ulib.Request(url, None, headers)
    json_string = ulib.urlopen(request).read()
    page = json.loads(json_string)
    new_soup = Soup(page[1][1], 'lxml')
    images = new_soup.find_all('img')
    links = [image['src'] for image in images]
    return links


def save_images(links, search_name):
    directory = search_name.replace(' ', '_')
    if not os.path.isdir(directory):
        os.mkdir(directory)

    for i, link in enumerate(links):
        savepath = os.path.join(directory, '{:06}.png'.format(i))
        ulib.urlretrieve(link, savepath)


if __name__ == '__main__':
    search_name = 'cell phones'
    links = get_links(search_name)
    save_images(links, search_name)

I got bunch of errors like this :

C:\Python36\python.exe "C:/dark/darkflow-master/new_model_data/part5 - get_images.py"
Traceback (most recent call last):

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
