手上有个notebook的.pynb文件，以及相关的csv数据文件
然后希望去Mac中调试。
记得之前VSCode说了，已支持notebook。
现在去试试
直接打开是文本文件
自动打开了调试界面
稍等一会，终于加载出来了：
点击第一个按钮后，报错：
【已解决】VSCode中运行Jupyter报错：Error Data Science libraries notebook and jupyter are not installed
然后再去运行看看：
【已解决】VSCode中运行Jupyter报错：We encountered an issue downloading the Language Server
然后去运行
此处缺少库，去安装：
【已解决】Mac中给Python 3.7中安装python库numpy和pandas
然后再去，给pyenv安装的python 3.7中，安装之前VSCode中初始化notebook的库：
回顾之前的：
【已解决】VSCode中运行Jupyter报错：Error Data Science libraries notebook and jupyter are not installed
看到了，最核心就是：
pip install -U jupyter pip install -U notebook
所以此处去给pyenv的python 3.7.3
➜ ~ pyenv version 3.7.3 (set by /Users/crifan/.pyenv/version) ➜ ~ python --version Python 3.7.3 ➜ ~ which python /Users/crifan/.pyenv/shims/python
中：
pip install jupyter notebook

然后再去VSCode中，切换到当前python 3.7.3
重启VSCode，点击ipynb文件，才能触发python插件：
然后切换过来：
切换后：
注意到，对应VSCode的配置：
.vscode/settings.json
{
"python.pythonPath": "/usr/local/opt/python/bin/python3.7"
}变成：
{
"python.pythonPath": "/Users/crifan/.pyenv/versions/3.7.3/bin/python"
}
【已解决】VSCode中的Jupyter的notebook已切换当前Python版本后但还是报错ModuleNotFoundError
然后继续报错：
ModuleNotFoundError Traceback (most recent call last)
in
----> 1 import torch
2 from torch.autograd import Variable
3 import torch.optim as optim
4 import matplotlib.pyplot as plt
5 get_ipython().run_line_magic('matplotlib', 'inline')
ModuleNotFoundError: No module named 'torch'
然后发现
import torch
是少了torch
现在先去确认python版本：
➜ debugNotebook python --version Python 3.7.3 ➜ debugNotebook which python /Users/crifan/.pyenv/shims/python ➜ debugNotebook pyenv which python /Users/crifan/.pyenv/versions/3.7.3/bin/python
再去安装：
➜ debugNotebook pip install torch Looking in indexes: http://mirrors.aliyun.com/pypi/simple/ Collecting torch Downloading http://mirrors.aliyun.com/pypi/packages/4a/72/0282449efe6e8a7ab6354ac990b8275bd8c881dcbf95b3ef0a041da3897b/torch-1.4.0-cp37-none-macosx_10_9_x86_64.whl (81.1 MB) |████████████████████████████████| 81.1 MB 254 kB/s Installing collected packages: torch Successfully installed torch-1.4.0
即可。
其中报错：

继续：
好像要生成图片，提示要等一会：
Matplotlib is building the font cache using fc-list. This may take a moment.
算了，重新运行：
重新试试，点击了 显示 星号* loading
看来表示正在运行
等了会，终于有结果了：
继续向下运行，最后：
终于算是运行完毕了。
【总结】
此处Mac中VSCode中调试和运行Jupyter的ipynb文件的过程是：
1.VSCode中选择好某个版本的Python
此处最后是Pyenv安装的Python 3.7.3
pyenv install 3.7.3 pyenv global 3.7.3
VSCode中选择此处的Python 3.7.3
2.安装ipynb中代码所依赖的库
pip install notebook juypter pandas numpy torch matplotlib
3.选择Jupyter的notebook界面中的server所用Python版本
点击界面右上角的位置，选择Python的版本
或：
查看-》命令面板-》Python: Select Interpreter to start Jupyter server
然后选择，和VSCode中选择的一样的Python，此处的：Python 3.7.3
4.然后即可开始点击调试代码
