settings.get("MY_CONFIG", None)

这段代码是在 Python 中读取指定配置文件中的 MY_CONFIG 配置项的值。其中，settings 是一个配置对象，可以是一个字典、一个配置文件等，get() 方法是获取指定键的值，第一个参数是键名，第二个参数是默认值，如果指定的键不存在，则返回默认值。在这里，如果 MY_CONFIG 存在则返回其值，否则返回 None。

在您提供的代码中，第一行需要将多个导入语句分开，即：

import os
import time
import platform
from selenium import webdriver as webdriver1
from selenium.webdriver.ie.options import Options
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from config import global_wait,root_url,use_edge,iedriver_path,edgedriver_path,chromedriver_path
from public.basiclogger import LOGGING

此外，我还注意到您的代码缩进存在问题，建议仔细检查缩进是否正确，以确保代码可以正确执行。

这个错误提示表明在安装 `opencv-python` 库时出现了问题。根据错误日志显示的信息，可能是由于使用的 Python 版本较旧，导致某些函数或方法不兼容。

解决方法如下：

1. 首先，确认你使用的 Python 版本是否符合 `opencv-python` 库的要求。你可以查看该库的文档或官方网站以确定所需的最低 Python 版本。

2. 如果你的 Python 版本较旧，尝试升级到较新的版本。Python 2.7 已经不再得到官方支持，建议升级到 Python 3.x 版本。

3. 如果你需要在 Python 2.7 中使用 `opencv-python` 库，可以尝试安装较旧版本的该库。你可以使用以下命令尝试安装指定版本的 `opencv-python`：

   pip install opencv-python==<version>

将 `<version>` 替换为你希望安装的具体版本号。

4. 如果以上方法都没有解决问题，建议尝试使用其他方式安装 `opencv-python`，例如通过源代码编译和安装。你可以从 `opencv-python` 官方仓库中获取源代码，并按照其提供的安装说明进行操作。

如果问题仍然存在，请提供更多的环境信息和错误日志，这样我才能更好地帮助你解决问题。
