我无法从Databricks中运行Selenium。我在其他各种线程中遵循了其他人的步骤：

How to use Selenium in Databricks and accessing and moving downloaded files to mounted storage
cannot get selenium webdriver to work in azure databricks
我的代码目前看起来像这样：

%sh
sudo add-apt-repository ppa:canonical-chromium-builds/stage
/usr/bin/yes | sudo apt update
/usr/bin/yes | sudo apt install chromium-browser

import os 
from webdrivermanager import ChromeDriverManager
from selenium import webdriver

cdd = ChromeDriverManager().download_and_install()

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--remote-debugging-port=9009')

driver = webdriver.Chrome(executable_path=cdd[0], options=chrome_options)

# Test driver connection
driver.get("https://www.google.com")
driver.find_element_by_css_selector("img").get_attribute("alt")

例外情况：

对我有效的是这个方法，它来自kindofhungry的问题中的源you linked。
我无法在Databricks中成功使用Web驱动程序管理器。

%sh
pip install selenium

# imports needed for notebook
from datetime import datetime
import dateutil.relativedelta
import os
import time
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.support.ui import WebDriverWait

下载并解压缩Chrome驱动程序并确保其为最新版本

%sh
version=`curl -sS https://chromedriver.storage.googleapis.com/LATEST_RELEASE`

wget -N https://chromedriver.storage.googleapis.com/${version}/chromedriver_linux64.zip  -O /tmp/chromedriver_linux64.zip

unzip /tmp/chromedriver_linux64.zip -d /tmp/chromedriver/

我需要获取Ubuntu更新，请参阅this帖子

%sh
sudo rm -r /var/lib/apt/lists/* 
sudo apt clean && 
   sudo apt update --fix-missing -y

添加chrome和必要的软件包

%sh
sudo curl -sS -o - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add
sudo echo "deb https://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list
sudo apt-get -y update
sudo apt-get -y install google-chrome-stable

设置浏览器

def init_chrome_browser(download_path, chrome_driver_path,  url):
     
    options = Options()
    prefs = {'download.default_directory' : download_path, 'profile.default_content_setting_values.automatic_downloads': 1, "download.prompt_for_download": False,
  "download.directory_upgrade": True,   "safebrowsing.enabled": True ,
  "translate_whitelists": {"vi":"en"},
  "translate":{"enabled":"true"}}
    options.add_experimental_option('prefs', prefs)
    options.add_argument('--no-sandbox')
    options.add_argument('--headless')    # wont work without this feature in databricks can't display browser
    options.add_argument('--disable-dev-shm-usage')
    options.add_argument('--start-maximized')
    options.add_argument('window-size=2560,1440')
    options.add_argument('--ignore-certificate-errors')
    options.add_argument('--ignore-ssl-errors')
    options.add_argument('--lang=en')
    options.add_experimental_option('excludeSwitches', ['enable-logging'])
    print(f"{datetime.now()}    Launching Chrome...")
    browser = webdriver.Chrome(service=Service(chrome_driver_path), options=options)
    print(f"{datetime.now()}    Chrome launched.")
    #print('Pausing to allow for translation options to kick in')
    #time.sleep(15) # Adding this line worked for some for translation but not for me
    browser.get(url)
    print(f"{datetime.now()}    Browser ready to use.")
    return browser

现在你可以测试它，根据需要更改url，你也可以更改下载路径，我能够指向blob存储中我的数据湖中的文件夹，并通过点击下载链接下载项目，只需等待几秒钟，然后关闭浏览器，以便有时间下载

driver = init_chrome_browser(
    download_path="/tmp/downloads",
    chrome_driver_path="/tmp/chromedriver/chromedriver",
    url= "https://www.google.com"
)

现在您应该可以运行代码了

driver.find_element_by_css_selector("img").get_attribute("alt")
