oct2py 导入错误:系统找不到指定的文件

Question

我正在尝试在我的一个python脚本中使用oct2py，我已经在C:OctaveOctave-4.2.1中安装了octave，并为我的用户帐户添加了C:OctaveOctave-4.2.1到我的PATH变量中。当我运行from oct2py import octave时，出现以下错误：

Traceback (most recent call last):

编辑：将OCTAVE_EXECUTABLE添加到我的路径后，我收到错误

Answer 1

更改 PATH 变量后是否重新启动了系统？

我以前在加载不同的模块时遇到过这个问题，并通过重新启动系统解决了这个问题。

Answer 2

通过添加路径变量OCTAVE_EXECUTABLE并将OCTAVE_EXECUTABLE值设置为C:OctaveOctave-4.2.1binoctave-cli.exe来修复。我还从我的 PATH 中删除了八度参考
