똑같이 적어서 실행을 했는데, 제 컴퓨터에선

IndexError                                Traceback (most recent call last)
c:\windows\temp/ipykernel_99852/1573255598.py in <module>
     66     # 큰 이미지 주소 추출
     67     if i == 1:
---> 68         target = browser.find_elements_by_css_selector("img.n3VNCb")[0]
     69     else:
     70         target = browser.find_elements_by_css_selector("img.n3VNCb")[1]

IndexError: list index out of range

이렇게 계속 에러가 뜹니다.. 뭐가 잘못된 걸까요?
