Currently, I am in the process of developing a PyQt5 application using the designer to create interfaces and then exporting them as .ui files. These files are subsequently loaded by my primary class. Below is an excerpt from my code snippet, named main.py:
main.py
import os.path
import PyQt5.QtWidgets as qtw
from PyQt5.uic import loadUi
import sys
class MainUI(qtw.QMainWindow):
def __init__(self, parent=None):
super(MainUI, self).__init__()
self._ui_path = os.path.dirname(os.path.abspath(__file__))
loadUi(os.path.join(self._ui_path, 'main.ui'), self)
if __name__ == "__main__":
# Initialize the application
app = qtw.QApplication(sys.argv)
# Create and display the main window of the application
win = MainUI()
win.show()
sys.exit(app.exec())
main.ui
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
<class>MainWindow</class>
<widget class="QMainWindow" name="MainWindow">
<property name="geometry">
<rect>
<x>0</x>
<y>0</y>
<width>320</width>
<height>240</height>
</rect>
</property>
<property name="windowTitle">
<string>MainWindow</string>
</property>
<widget class="QWidget" name="centralwidget">
<widget class="QPushButton" name="pushButton">
<property name="geometry">
<rect>
<x>110</x>
<y>100</y>
<width>88</width>
<height>27</height>
</rect>
</property>
<property name="text">
<string>ok</string>
</property>
</widget>
</widget>
<widget class="QMenuBar" name="menubar">
<property name="geometry">
<rect>
<x>0</x>
<y>0</y>
<width>320</width>
<height>21</height>
</rect>
</property>
</widget>
<widget class="QStatusBar" name="statusbar"/>
</widget>
<resources/>
<connections/>
</ui>
To generate an executable for this project, I utilize pyinstaller with the command pyinstaller -F -w main.py.
Upon initial execution, the executable file must be located in the same directory as the .ui file. To resolve issues related to loading the UI, I modified the loadUI function based on the response provided here.
However, upon running the executable, an error message emerged along with the following traceback:
Traceback (most recent call last):
File "main.py", line 17, in <module>
win = MainUI()
File "main.py", line 11, in __init__

File "xml\etree\ElementTree.py", line 584, in parse
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\username\\AppData\\Local\\Temp\\_MEI187162\\main.ui'
The issue arises from the fact that after executing the .exe file, a temporary directory is created containing various dll files. Unfortunately, the program attempts to locate the .ui file within this directory, leading to failure. What steps can I take to direct the executable to the correct location of the .ui file?
