Question

我想使用ipython的octave功能。因此，我通过pip命令安装了oct2py模块。（确切地说，我正在使用ipython3和pip3命令）

安装本身已成功完成。根据{{3}}，我在ipython终端模式下尝试了以下命令。

In [1]: %load_ext octavemagic

- ＆GT; ％octave显然可用。

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

- ＆GT; ipython说以下错误信息。

如果没有Oct2PyError，我怎么能使用octavemagic？任何帮助，将不胜感激。提前谢谢。

Answer 1

我从this page找到解决方案。对不起，我很抱歉。

以下命令正常工作。

In [1]: %load_ext oct2py.ipython

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

当使用octavemagic时，在ipython中会出现Oct2PyError
