推荐答案
Google合作实验室
Colaboratory 是免费的Jupyter笔记本环境，需要无需设置，并且完全在云中运行，这使我们能够编写和执行代码，保存和共享您的分析以及访问强大的计算资源，而这一切都可以从您的浏览器免费获得.
Google Colaboratory
Colaboratory is a free Jupyter notebook environment that requires no setup and runs entirely in the cloud which enables us to write and execute code, save and share your analyses, and access powerful computing resources, all for free from your browser.
整个合作实验室都在云VM中运行.如果调查VM，您会发现当前的colab笔记本正在Ubuntu 18.04.3 LTS之上运行.
The entire colab runs in a cloud VM. If you investigate the VM you will find that the current colab notebook is running on top of Ubuntu 18.04.3 LTS.
因此，在使用 Selenium 时，没有提及 WebDriver 变体对于扩展名，即.exe，您需要删除扩展名.因此，有效的代码块将是:
So while using Selenium instead of mentioning the WebDriver variant along with the extension i.e. .exe you need to drop the extension. So effectively your code block will be:
import selenium
from selenium import webdriver
wd = webdriver.Chrome('/content/chromedriver')
更新
如果您不确定 ChromeDriver a>正在下载，您可以将其移动到已知位置并按以下方式使用它:
Update
Incase you aren't sure where the ChromeDriver is getting downloaded you can move it to a known location and use it as follows:
!apt-get update
!apt install chromium-chromedriver
!cp /usr/lib/chromium-browser/chromedriver /usr/bin
!pip install selenium
from selenium import webdriver
wd = webdriver.Chrome('/usr/bin/chromedriver')
