How to solve the problem with Ui_MainWindow()?

Question

PyQt

Hello, I decided to make a calculator in Python with an interface, and not through the console as usual, I use the library - PySide6 . I did everything in order as on the site, the link is https://habr.com/en/post/587276 , and besides, there is a video on YouTube.
Here is the actual error:

AttributeError: 'Ui_MainWindow' object has no attribute 'le_entry'

The error starts from the moment I start using - le_entry , please help me solve the problem, I don’t know what to do with it, I googled, as a result - I didn’t find anything for everyone else errors.
Thanks in advance!
