代码：
from selenium.webdriver.common.action_chains import ActionChains
from selenium import webdriver
import time
driver = webdriver.Firefox()
driver.get("https://www.baidu.com/")
print(driver)
driver.implicitly_wait(10)
报错：

ps：selenium3.4.1+firefox53

问题已经解决，原来是我下载的geckodriver.exe版本过低，目前的搭配版本是selenium3.4.1+firefox53.0+geckodriver.exe 0.15
