我想使用ipython的八度功能。 因此,我通過pip命令安裝了oct2py模塊。 (準確地說,我使用ipython3和pip3命令)當使用octavemagic時,ipython發生了Oct2PyError

安裝本身已成功完成。 根據this web page,我在ipython終端模式下嘗試了以下命令。

In [1]: %load_ext octavemagic 

- >%octave變得明顯可用。

In [2]: x = %octave [1 2; 3 4];x 

- > ipython表示以下錯誤信息。

如何在沒有Oct2PyError的情況下使用octavemagic? 任何幫助,將不勝感激。提前致謝。

我找到this page解決方案。 我很抱歉不知道這一點。

以下命令正常工作。

In [1]: %load_ext oct2py.ipython 

In [2]: x = %octave [1 2; 3 4];
