python - 在 Jupyter 笔记本上找不到 Matplotlib

Question

我是命令行编程的新手，所以请多多包涵。我一直在尝试使用以下命令在我的 Jupyter 笔记本中内联运行 matplotlib：

%matplotlib inline

我收到以下错误

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-88ca88d21acc> in <module>

    281 
    282     if gui and gui != 'auto':

ModuleNotFoundError: No module named 'matplotlib'

在我的命令行上运行 python 和 Ipython 之后，我确信它们都通过相同的 python 3.8.3 安装运行。如果是这种情况，我不确定为什么 pylabtools.py 脚本无法使用 matplotlib 库。

作为参考，我使用位于https://medium.com/@henriquebastos/the-definitive-guide-to-setup-my-python-workspace-628d68552e14的说明安装了所有内容。
