oct2py導入錯誤：系統找不到指定的文件

Question

我正在嘗試在我的python腳本之一中使用oct2py，我在C:\\Octave\\Octave-4.2.1安裝了C:\\Octave\\Octave-4.2.1並已將C:\\Octave\\Octave-4.2.1到我的用戶帳戶的PATH變量中。 當我from oct2py import octave運行時from oct2py import octave以下錯誤：

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

    octave = Oct2Py()

    self.restart()

    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

編輯：將OCTAVE_EXECUTABLE添加到我的路徑后，我得到了錯誤

Answer 1

更改PATH變量后是否重新啟動系統？

在加載其他模塊並通過重新啟動系統解決該問題之前，我曾遇到過此問題。

Answer 2

通過添加路徑變量OCTAVE_EXECUTABLE並將OCTAVE_EXECUTABLE值設置為C:\\Octave\\Octave-4.2.1\\bin\\octave-cli.exe了修復。 我還從PATH中刪除了八度音階參考
