0、 初步报错情况
根据原链接，已确定安装成功，运行demo时出现报错，不能正常运行

1、
参照-PhySO- 物理符号回归建模方法 —— 中文注释项目找寻一点线索，文中提及#库的调用： monitoring；benchmark；physo，尝试进行相应安装。
通过pip install monitoring和conda install benchmark顺利安装了两个库，再次运行后仍然同样报错
注意到报错中的No such file or directory: 'latex'，接下来尝试安装latex，根据Ubuntu安装LaTeX
仅仅执行sudo apt-get install texlive-full后，报错部分就少了两个FAIL报错：

OK
接下来继续完成latex 的安装步骤，报错同上。

遇到一个新的问题，cuda不能使用？
