求解答呀，selenium是cmd中用pip直接下载的，正确安装了chromedriver，path也配置了，输入
from selenium import webdriver
driver = webdriver.Chrome()
后仍然报错如下：
Traceback (most recent call last):
File "C:\Users\baobei\AppData\Local\Programs\Python\Python36\lib\site-packages\selenium\webdriver\common\service.py", line 74, in start
stdout=self.log_file, stderr=self.log_file)

During handling of the above exception, another exception occurred:
