我正在尝试在我的一个 python 脚本中使用 oct2py，我已经安装了 octaveC:\Octave\Octave-4.2.1并已为我的用户帐户添加C:\Octave\Octave-4.2.1到我的 PATH 变量中。当我运行时，from oct2py import octave我收到以下错误：

Traceback (most recent call last):
  File "C:\Users\CVanCleef\Desktop\cvancleef reconstruction\filterTestin.py", line 12, in <module>
    from oct2py import octave

    octave = Oct2Py()

编辑：将 OCTAVE_EXECUTABLE 添加到我的路径后，出现错误

更改 PATH 变量后是否重新启动系统？

我之前在加载不同的模块并通过重新启动系统解决它之前遇到过这个问题。

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