我希望硒在截图之前等待。当我使用 time.sleep(1( 时，它给了我这个错误：

这是我的代码：
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.support.ui import WebDriverWait
import os
import time
options = Options()
options.add_argument("--headless")
driver = webdriver.Firefox(firefox_options=options, executable_path =
'/usr/local/bin/geckodriver', log_path=os.devnull)
driver.get('https://google.com/')
time.sleep(5)
driver.save_screenshot('page.png')
driver.quit()
如何等待页面加载而不会收到此错误？
我知道你可以等待一个元素加载，我只想在没有任何条件的情况下等待它。
(当然，没有什么可加载的了 google.com 我只是做了这个例子来使问题复活节。
要添加无条件等待以在硒中driver.get(URL)，请使用n = time/seconds和循环driver.set_page_load_timeout(n)：
driver.set_page_load_timeout(n) # Set timeout of n seconds for page load
loading_finished = 0 # Set flag to 0
while loading_finished == 0: # Repeat while flag = 0
try:
sleep(random.uniform(0.1, 0.5)) # wait some time
website = driver.get(URL) # try to load for n seconds
loading_finished = 1 # Set flag to 1 and exit while loop
except:
logger.warn("timeout - retry") # Indicate load fail
else:
driver.save_screenshot('page.png') # In case of flag = 1
driver.close()
driver.quit()
# this code will will keep looping until the element is find so whatever how
# much time the page will take time to load .
driver = webdriver.Firefox(executable_path=r'./geckodriver')
