Octave 4.2.2 和 sympy 1.6 [英] Octave 4.2.2 and sympy 1.6

问题描述

我正在尝试将 Octave 4.2.2 与 Symbolic pkg v.2.9.0 一起使用，但出现与 sympy 包相关的错误:

Iam trying to use Octave 4.2.2 with Symbolic pkg v.2.9.0 but I get this error related to sympy package:

Your kit looks good for running the Symbolic package.  Happy hacking!

我深入研究代码并找到这两个参考:

I dig into code and find this two references:

https://github.com/sympy/sympy/pull/18245https://github.com/sympy/sympy/pull/19316

但我不是程序员，所以非常感谢任何想法.

But Iam not a programmer so any idea is greatly appreciated.

我尝试卸载 sympy-1.6 并安装 sympy-1.5，但这不起作用.

I tried to uninstall sympy-1.6 and install sympy-1.5 but that doesn't work.

感谢您的时间.

推荐答案

我已经找到了答案.问题出在 sympy 1.6 版上，所以我使用 pip3 将其降级到 1.5.1 版.

I have managed to found the answer. The problem is on sympy version 1.6 so I downgraded it to version 1.5.1 with pip3.
