Using UI class from another directory

[Joimar]

Hi everyone, I'm facing some problems with PyQT/Pyside when importing from another directory my UI classes. I'm showing the code below.

Here's my UI Class in "UIClasses" directory

# This Python file uses the following encoding: utf-8
import sys

from PySide6.QtWidgets import QApplication, QMainWindow

# Important:
# You need to run the following command to generate the ui_form.py file
#     pyside6-uic form.ui -o ui_form.py, or
#     pyside2-uic form.ui -o ui_form.py
#from UIMainWindow import Ui_MainWindow
from UIClasses\mainwindow import Ui_MainWindow
class MainWindow(QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.ui.pushButton.clicked.connect(self.pressButton)
        self.ui.actionNew.triggered.connect(self.pressButton)

    def pressButton(self):
        self.ui.pushButton.setText("Foi Clicado")

Here's my UI Python File converted from .ui

from PySide6.QtCore import (QCoreApplication, QDate, QDateTime, QLocale,

        if not MainWindow.objectName():
            MainWindow.setObjectName(u"MainWindow")

        self.pushButton.setObjectName(u"pushButton")

        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QMenuBar(MainWindow)
        self.menubar.setObjectName(u"menubar")
        self.menubar.setGeometry(QRect(0, 0, 800, 21))
        self.menuFile = QMenu(self.menubar)
        self.menuFile.setObjectName(u"menuFile")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QStatusBar(MainWindow)
        self.statusbar.setObjectName(u"statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.menubar.addAction(self.menuFile.menuAction())
        self.menuFile.addAction(self.actionNew)

        self.retranslateUi(MainWindow)

        QMetaObject.connectSlotsByName(MainWindow)
    # setupUi

    def retranslateUi(self, MainWindow):
        MainWindow.setWindowTitle(QCoreApplication.translate("MainWindow", u"MainWindow", None))
        self.actionNew.setText(QCoreApplication.translate("MainWindow", u"New", None))
        self.pushButton.setText(QCoreApplication.translate("MainWindow", u"PushButton", None))
        self.menuFile.setTitle(QCoreApplication.translate("MainWindow", u"File", None))
    # retranslateUi

Here's my main file

# This Python file uses the following encoding: utf-8
import sys

from PySide6.QtWidgets import QApplication
from UIClasses.mainwindow import MainWindow
#from mainwindow import MainWindow


if __name__ == "__main__":
    app = QApplication(sys.argv)
    widget = MainWindow()
    widget.show()
    sys.exit(app.exec())

But for some reason I'm having this error

When I change the project to have all files in the same folder, everything works fine. I only have troubles when I try to separete the files in different folders.

@Joimar said in Using UI class from another directory:

from UIClasses\mainwindow import Ui_MainWindow

Shouldn't it be

from UIClasses.mainwindow import Ui_MainWindow

?
