mindspore 1.3 for ubuntu 18.04安装后报libgmpxx.so.4打不开的错的解决。

在ubuntu 18.04上（就是200DK的那个板子的宿主机）安装好MindSpore 1.3之后，

检查：发现报错：

ascend@ubuntu:~/mindspore1.3$ python3 
Python 3.7.5 (default, Mar 26 2021, 23:32:34) 
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import mindspore as ms
Traceback (most recent call last):

    from .._c_expression import typing, EnvInstance_
ImportError: libgmpxx.so.4: cannot open shared object file: No such file or directory

不知道是什么情况。。。

还是报这个错：
