Does ROS system offer any methods to hide the source code?

Because I receive a requirement to hide my ROS code.

Thus, I choose pyinstaller to make .py file into the executable file

After finishing the compile by command: pyinstaller -F

Then, using launch file to launch the executable file

But it shows up a ImportError: cannot import name motorCmd (where "motorCmd" is a self-defined msg file I make)

I have tried the following method and still cannot resolve the problem:

  1. Put msg file with the executable file at the same path (ie: "dist" dir, which is auto-generated by pyinstaller).
  2. Make a hook-file under the pyinstaller hooks dir as following:


    from PyInstaller.utils.hooks import collect_data_files

    datas = collect_data_files("package") #package is ros package under the "catkin_ws" path


OS : ubuntu 16.04

ROS version: Kinetic

You are against the spirit of ROS by hiding your code.
