Problem with Pyinstaller and loadUiType in PySide2
If you're experiencing issues with PyInstaller and loadUiType
in PySide2, it could be related to how PyInstaller handles the packaging of PyQt/PySide modules. PyInstaller may not be able to automatically detect and include the necessary files for PySide2's loadUiType
function.
To resolve this issue, you can try the following steps:
Use the
--hidden-import
option: When running PyInstaller, specify the--hidden-import
option to explicitly tell PyInstaller to include the required modules. For example:csspyinstaller --hidden-import=PySide2.QtUiTools main.py
Manually import
uic
andloadUiType
: Instead of relying onloadUiType
, you can manually importuic
and use itsloadUiType
function. Modify your code to include the following imports:pythonfrom PySide2.QtUiTools import QUiLoader
from PySide2.QtWidgets import QApplication
# ...
ui_file = 'path_to_ui_file.ui'
ui_type, ui_base = uic.loadUiType(ui_file)
This approach ensures that
uic
is explicitly imported, and PyInstaller will include the necessary modules during the packaging process.Modify the PyInstaller spec file: If the above steps do not work, you can create a PyInstaller spec file and manually specify the required imports and data files. To do this, create a file named
your_script.spec
and modify it as follows:python# your_script.spec
from PyInstaller.utils.hooks import collect_data_files
from PyInstaller.utils.hooks.qt import pyqt5_plugins
datas = collect_data_files('PySide2')
# If using PyQt5 instead of PySide2, use:
# datas = pyqt5_plugins('PySide2')
a = Analysis(['main.py'], pathex=['path_to_script_directory'], datas=datas, ...)
Replace
'main.py'
with your main Python script and'path_to_script_directory'
with the directory containing your script. Then, when running PyInstaller, use the spec file instead:pyinstaller your_script.spec
These steps should help ensure that PyInstaller properly includes the necessary modules and data files required for loadUiType
in PySide2.
