【问题描述】：

我需要加载我现有的完整 google chrome 配置文件，其中包含我登录 google 和站点帐户的所有 chrome 扩展。我正在为这段代码苦苦挣扎，某处出现语法错误

chrome_options = Options()
chrome_options.add_argument('user-data-dir= C:\Users\DMMaxim\AppData\Local\Google\Chrome\User Data')
capabilities = DesiredCapabilities.CHROME.copy()
chromedriver = r"C:\Users\DMMaxim\Desktop\chromedriver_win32\chromedriver.exe" 
driver = webdriver.Chrome(executable_path=chromedriver, chrome_options = chrome_options, desired_capabilities=capabilities)

我得到这个错误

C:\Users\DMMaxim\Desktop>python ExportbacktestTradingview.py
  File "ExportbacktestTradingview.py", line 21
    chrome_options.add_argument('--user-data-dir=C:\Users\DMMaxim\AppData\Local\Google\Chrome\User Data')
                               ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 18-19: truncated \UXXXXXXXX escape

这是我的完整代码
