python selenium:无法单击不可见元素

我正试图通过以下方式刮取谷歌新闻页面:

from selenium import webdriver
import time
from pprint import pprint


base_url = 'https://www.google.com/'

driver = webdriver.Chrome('/home/vincent/wintergreen/chromedriver') ## change here to your location of the chromedriver
driver.implicitly_wait(30)
driver.get(base_url)


input = driver.find_element_by_id('lst-ib')
input.send_keys("brexit key dates timetable schedule briefing")

click = driver.find_element_by_name('btnK')
click.click()

news = driver.find_element_by_link_text('News')
news.click()

tools = driver.find_element_by_link_text('Tools')
tools.click()

time.sleep(1)

recent = driver.find_element_by_css_selector('div.hdtb-mn-hd[aria-label=Recent]')
recent.click()

# custom = driver.find_element_by_link_text('Custom range...')
custom = driver.find_element_by_css_selector('li#cdr_opt span')
custom.click()

from_ = driver.find_element_by_css_selector('input#cdr_min')
from_.send_keys("9/1/2018")

to_ = driver.find_element_by_css_selector('input#cdr_max')
to_.send_keys("9/2/2018")

time.sleep(1)

go_ = driver.find_element_by_css_selector('form input[type="submit"]')
print(go_)
pprint(dir(go_))
pprint(go_.__dict__)
go_.click()

此脚本可以输入搜索条件,切换到“新闻”选项卡,打开“自定义时间段”选项卡,填写开始日期和结束日期,但在该点之后未能单击“转到”按钮。

print 和 pprint selenium.common.exceptions.ElementNotVisibleException: Message: element not visible

有没有人能快速运行一下Selenium,并给我一些提示,说明它为什么会返回这样的错误?

谢谢!
