I'm trying to export my .py script to .exe using PyInstaller, which has dependencies on .ui files which were created using Qt Designer.
I can confirm that my .py script works just fine when running it through PyCharm - I'm able to see the GUI I've created with the .ui files.
However, when I export my .py script to .exe and launch it, I recieve the following errors in the command line:
C:\Users\giranm>"C:\Users\giranm\PycharmProjects\PyQt Tutorial\dist\secSearch_demo.exe"
Traceback (most recent call last):
File "secSearch_demo.py", line 13, in <module>

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\giranm\\securitySearchForm.ui'
Failed to execute script secSearch_demo
For some reason, the .exe file is looking for the .ui file within the path - C:\Users\giranm\
However, having done some research already, I was told that I needed to use os.getcwd() and ensure that I have the full path in my script. Even with the code below, I still get errors trying to locate the .ui files.
PyInstaller: IOError: [Errno 2] No such file or directory:
# import relevant modules etc...
cwd = os.getcwd()
securitySearchForm = os.path.join(cwd, "securitySearchForm.ui")
popboxForm = os.path.join(cwd, "popbox.ui")
Ui_MainWindow, QtBaseClass = uic.loadUiType(securitySearchForm)
Ui_PopBox, QtSubClass = uic.loadUiType(popboxForm)
# remainder of code below.
I'm aware that one can convert .ui files to .py and import them into the main routine using pyuic4. However, I will be making multiple edits to the .ui files and thus it is not feasible for me to keep converting them.
Is there anyway to fix this so that I can create a standalone .exe?
I'm fairly new to using PyQT4 and PyInstaller - any help would be much appreciated!
After scratching my head all weekend and looking further on SO, I managed to compile the standalone .exe as expected using the UI files.
Firstly, I defined the following function using this answer
Bundling data files with PyInstaller (--onefile)
# Define function to import external files when using PyInstaller.
def resource_path(relative_path):
""" Get absolute path to resource, works for dev and for PyInstaller """
try:
# PyInstaller creates a temp folder and stores path in _MEIPASS
base_path = sys._MEIPASS
except Exception:
base_path = os.path.abspath(".")
return os.path.join(base_path, relative_path)
Next I imported the .UI files using this function and variables for the required classes.
# Import .ui forms for the GUI using function resource_path()
securitySearchForm = resource_path("securitySearchForm.ui")
popboxForm = resource_path("popbox.ui")
Ui_MainWindow, QtBaseClass = uic.loadUiType(securitySearchForm)
Ui_PopBox, QtSubClass = uic.loadUiType(popboxForm)
I then had to create a resource file (.qrc) using Qt Designer and embed images/icons using this resource file. Once done, I used pyrcc4 to convert the .qrc file to .py file, which would be imported in the main script.
Terminal
C:\Users\giranm\PycharmProjects\PyQt Tutorial>pyrcc4 -py3 resources.qrc -o resources_rc.py
Python
import resources_rc
Once I have confirmed the main .py script works, I then created a .spec file using PyInstaller.
Terminal
C:\Users\giranm\PycharmProjects\PyQt Tutorial>pyi-makespec --noconsole --onefile secSearch_demo.py
As per PyInstaller's guide, I've added data files by modifying the above .spec file.

Finally, I then compiled the .exe using the .spec file from above.
