pyinstaller multiple py files import in an exe, error when creating process

Question

I am currently developing a GUI in PyQt5
I have several py files:

• 1) program.py
• 2) content.py

1) program.py

This contains some additions such as actions by pressing a button as well as the import of the icon.

2) content.py

Here is where the graphic part of the program is, this one had created it with PyQt5 designer, and converted to py with pyuic5.

when I link with python:

pyinstaller program.py

it is an error and I have also tried creating a .py file that links to both .py and p files..

link.py

#contains

import program.py
import contenido.py
