Question

按照https://github.com/Calysto/octave_kernel的说明在Windows1计算机上安装octave_kernel，一切正常。但是，当我从Jupyter中选择Octave作为我的核心时，会发生以下情况。

内核已经死亡，自动重启失败。它是可能内核无法重启。如果你不能重新启动内核，你仍然可以保存笔记本，但是在重新打开笔记本之前，运行代码将不再有效。

我也无法让oct2py工作。

来自octave_kernal尝试的Jupyter控制台输出如下。

我看到了权限错误并尝试以管理员身份运行Jupyter无济于事。

将环境变量OCTAVE_EXECUTABLE设置为C：\ Octave \ Octave-4.2.1 \ bin \ octave-cli-4.2.1.exe。为Octave安装文件夹上的所有用户提供完整的R / W权限
