You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Answer 1

您应该按照错误消息中的建议更新点子。如果它与可能已过时的TLS版本有关，则可以解决您的问题。

Answer 2

打开anaconda导航器，尝试从笔记本内部升级jupyternotebook和导航器，否则您应该重新安装，实际上我也遇到了这个问题。我在互联网上进行了大量搜索，但最后我卸载并重新安装了它，然后下载了所有的库，现在一切正常。
