【未解决】VSCode中调试Notebook的ipynb文件中的Python代码
期间，点击第一个按钮后，报错：
Error: Jupyter cannot be started.

弹出提示，问是否要安装：
Data Science libraries jupyter and notebook are not installed in interpreter Python 3.7.3 64-bit.
点击Install
下载好慢，最后终于安装好了：

此处运行报错
Error: Jupyter cannot be started. Error attempting to locate jupyter: Data Science libraries notebook and jupyter are not installed in interpreter Python 3.7.3 64-bit.
的原因是：
notebook和jupyter都没有安装。根据VSCode的提示，点击Install，去安装（等待足够长时间）后，即可。
