You are using pip version 9.0.3, however version 26.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
【分析问题】这个说明安装pywinpty出现问题，首先先进行pip的更新。
更新后继续安装jupyter notebook，发现了确实是对应的版本问题
但更新后的pip自动解决了该问题，最后成功安装上jupyter notebook。
再继续安装tensorflow，
测试下tensorflow。
成功安装上。
