我正在尝试编写脚本来帮助我跟踪Fitbit社区，但是首先我需要登录该站点。原谅我，因为我是编码新手。我使用Selenium在Python。我的代码如下：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC


import time
import re

##Loading selenium to handle java on leaderboard page 
##

path_to_chromedriver = 'C:/python351/chromedriver/chromedriver.exe'
browser2 = webdriver.Chrome(executable_path = path_to_chromedriver)

##Login with selenium
##

login_url = 'https://www.fitbit.com/login'
browser2.get(login_url)
browser2.implicitly_wait(5)


email1 = browser2.find_element_by_name('email')
password1 = browser2.find_element_by_name('password')
email1.click()
email1.clear()
WebDriverWait(browser2, 10)

email1.send_keys('[email protected]')
WebDriverWait(browser2, 20)
password1.click()
password1.clear()
WebDriverWait(browser2, 20)

password1.send_keys('madeuppass')
WebDriverWait(browser2, 20)



form1 = browser2.find_element_by_class('common-btn common-btn-submit track-Auth-Login-ClickFitbit')
form1.submit()

当我运行它时，我不断收到以下错误，并且电子邮件/密码框没有填写。这是回溯：

我已经摆弄了几个小时，但无法正常工作。我看到该元素看不见错误，这使我认为我需要延迟，但是后来我尝试实现它（可能效果很差），但仍然出现错误。我还添加了单击和清除的内容，并且在其他帖子中也看到了这些建议。我可以RoboBrowser使用表单提交来登录，但是稍后需要访问的某些内容使用了Java，因此最终Selenium陷入了僵局，现在我切换到了并被卡住了。
