如何制作 Mininet Python 脚本的可执行包？

我有 mininet 自定义拓扑 python 脚本，我需要在 Linux 中使可执行文件在未安装 mininet 的情况下工作。

我使它在 ubuntu-Pyinstaller 中可执行。它在安装了 mininet 的地方工作正常，但在没有安装 mininet 的其他机器上不能工作。在运行可执行文件时，它给出以下错误：

   pradeepkumar@ubuntu:~/Desktop/tp4$ sudo python tp.py
Traceback (most recent call last):
  File "tp.py", line 5, in <module>
    from mininet.net import Mininet
ImportError: No module named mininet.net

pradeepkumar@ubuntu:~/Desktop/tp4$ cd dist/

pradeepkumar@ubuntu:~/Desktop/tp4/dist$ ls
tp

pradeepkumar@ubuntu:~/Desktop/tp4/dist$ sudo ./tp
*** Test Network Script 
*** Creating nodes
Cannot find required executable mnexec.
Please make sure that Mininet is installed and available in your $PATH:
(/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin)
Traceback (most recent call last):

使用 NUITKA：

同样的问题，以及与上面完全相同的错误消息。

注意：我曾经在将包移动到另一台机器之前制作包的 tar.gz，然后在那里解压。

我尝试了他们用户手册中的所有命令以使其可执行但无法在第二台机器上运行......

下面是脚本：

#!/usr/bin/python

    global net

    Mininet.init()

    TP()

请告知我如何使这个mininet-python 脚本在 Linux 中的可执行包可以在没有安装 mininet 的其他机器上工作？

谢谢
