Dependencies Matlab Python编译器SDK失败，返回“0”；未定义符号：XML_SetHashSalt"；

我正在使用MatlabR2018A和Python3.6（安装了3.5和2.7，但未使用）开发Ubuntu 16.0464位

我有一个Matlab代码，它正试图通过使用并遵循上的说明从Python调用。我按照链接到word的所有说明进行操作，创建Matlab Python包装器（web）安装程序并安装它们，按照安装程序的建议更改LD_LIBRARY_路径。我已经尝试了他们展示的MagicSquarePkg示例，它在这种方法中运行良好。但是MagicSquarePkg没有使用任何Matlab工具箱函数；我的代码是这样的。使用代码执行此过程后，出现以下错误：

我们非常感谢您对解决此问题的任何帮助

编辑：凭直觉，我用Python2.7而不是3.6运行了我的Matlab模块，它似乎在使用2.7，但不是3.6

Not enough input arguments. *this is OK this means my function is getting called*

我有一个确切的问题。同样的错误。使用Python2.7代替Python3.5对我来说也很管用。谢谢

---

然而，我真的很想知道如何使它在3.6上工作，因为我打算在3.6上运行的Django服务器上使用Matlab程序。

我也有同样的问题。已解决：

cd /full_path_to_matlab_mcrroot/v94/bin/glnxa64
mv libexpat.so.1 libexpat.so.1.NOFIND

多亏了

• 说明：

/full\u path\u to\u matlab\u mcrroot/v94/bin/glnxa64/libexpat.so.1

指向

libexpat.so.1.5.0

但是

---

/lib/x86\u 64-linux-gnu/libexpat.so.1

指向

libexpat.so.1.6.0

什么对您有效？这应该是一个评论，而不是我所看到的答案。
