python - 如何将 matlab 合并到 jupyter notebook 中？

问题描述

我正在尝试集成 MATLAB 和 jupyter notebook，以便我可以在基于 Web 的笔记本和实验室中使用 MATLAB。我正在运行 MATLAB R2020a、python 3.6（来自 conda 4.8.2）；计算机的操作系统是 Ubuntu 18.04。我收到一条错误消息，提示未安装 MATLAB 引擎，但据我所知，它已安装。

我已经执行了以下步骤： 1. 我用 python 3.6 创建了一个 conda 环境conda create matlab-conda python=3.6。2. 从那里，我使用 pip 安装 matlab_kernel，输入pip install matlab-kernel. 3. 如果我通过键入并查看列表来检查内核是否已安装jupyter kernelspec list，它会显示： 可用内核：

ir /home/computerone/.local/share/jupyter/kernels/ir

matlab
/home/computerone/miniconda3/envs/matlab-conda/share/jupyter/kernels/matlab

python3
/home/computerone/miniconda3/envs/matlab-conda/share/jupyter/kernels/python3

  1. 为了配置 MATLAB，我找到了 extern/engines/python 文件夹，并从 conda env 中运行了 setup: python setup.py install。这成功运行了。

当我打开 juyter notebook 或 lab 时，MATLAB notebook 选项在那里，我可以选择它，显示一个 notebook；但是，当我打开 MATLABnotebook 并键入命令（例如，2+5）时，会引发以下错误：
