How to install these 3 modules with pyinstaller?

See more:

Python3.6

Hello,

I developed a Python script in 3.X which uses the xmlschema module and I have in the header of this script the following imports:

import xmlschema
import elementpath
import os

I am using pyinstaller to generate an executable, I manage to generate it but the executable does not work because it seems to be missing things.
Here is the command I type with pyinstaller to generate the executable.

pyinstaller --onefile checkXsd112.py -—hidden-import xmlschema --hidden-import elementpath --hidden-import os

In the Build directory, I have a file that contains warnings:

This file lists modules PyInstaller was not able to find. This does not
necessarily mean this module is required for running you program. Python and
Python 3rd-party packages include a lot of conditional or optional module. For
example the module 'ntpath' only exists on Windows, whereas the module
'posixpath' only exists on Posix systems.
 
Types if import:
* top-level: imported at the top-level - look at these first
* conditional: imported within an if-statement
* delayed: imported from within a function
* optional: imported within a try-except-statement
 
IMPORTANT: Do NOT post this list to the issue-tracker. Use it as a basis for
           yourself tracking down the missing module. Thanks!

I don't understand this file, yet I imported the 3 modules in the command line of Pyinstaller.

Would you know how to generate an executable with Pyinstaller by importing xmlschema, os and elementpath?

Thanks.
