ImportError: cannot import name 'get_host' from 'urllib3' (F:\coding\reptile\venv\lib\site-packages\urllib3\__init__.py)

根据引用至的内容，"ImportError: cannot import name 'get_host' from 'urllib3'"错误通常发生在安装了不兼容的opencv-python和opencv-contrib-python版本时。解决此错误的方法是删除这两个库并重新安装opencv-python及与之相匹配的版本的opencv-contrib-python。具体操作步骤如下：

1. 在pycharm或服务器的终端中执行以下命令来卸载不兼容的opencv-python-headless版本：

   pip uninstall opencv-python-headless

2. 接着，安装低于4.3版本的opencv-python-headless：

   pip install "opencv-python-headless<4.3"

这样，重新安装并匹配版本的opencv-python和opencv-contrib-python之后，应该可以解决"ImportError: cannot import name 'get_host' from 'urllib3'"错误。请尝试以上方法，并在评论区反馈是否解决了问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
