Windows 7上的Jupyter Octave內核

按照https://github.com/Calysto/octave_kernel上的說明在Windows1計算機上安裝octave_kernel，一切正常。但是，當我從Jupyter選擇Octave作爲我的內核時，會發生以下情況。Windows 7上的Jupyter Octave內核

The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.

我也無法使oct2py工作。

從octave_kernal企圖的Jupyter控制檯輸出如下。

我看到了權限錯誤，並試圖以管理員身份運行Jupyter無濟於事。

你能在命令提示符下運行「octave」還是「octave-cli」？ –

嗨托馬斯，是的。 Windows在找到Octave時沒有問題，無論是直接從運行還是從任何目錄中的PowerShell或cmd。我有兩個Octave和Jupyter直接安裝在C：\，我想知道如果這是問題，即使我有管理員權限。 – Clay

我還試圖在管理員模式下一個Python控制檯以下： '進口子，OS 可執行= os.environ [ 'OCTAVE_EXECUTABLE'] subprocess.check_output（[可執行， '--version']）' 相同錯誤： 'PermissionError：[WinError 5] Access denied' – Clay

將環境變量OCTAVE_EXECUTABLE設置爲C：\ Octave \ Octave-4.2.1 \ bin \ octave-cli-4.2.1.exe。向用戶提供完整的R/W權限Octave安裝文件夾中的每個人
