Help Converting .py to .exe

[MrLegend11]

Hello everyone,

I started learning Python a couple of weeks ago, and I've been working on a GUI application that performs several tasks. One of the features of my application is a script that allows users to select a folder directory. The script then converts and merges all Excel files within the subfolders into a single PDF file.

The script works perfectly when I run it in Visual Studio Code. However, after converting it into an executable (.exe) file, the Excel-to-PDF conversion script no longer functions correctly. It only manages to create the first folder named "PDF" and then stops without doing anything else.

Below is the script I'm using. Any help or suggestions would be greatly appreciated!

edited 08/25/24 - For some reason when I change the .spec file to Console=True, the script works when it's converted to .exe however the console is on and displaying messages all the time. How can I make it so that the Cmd console doesn't show?

[deanhystad]

What OS?

When you run the script, is there a console? If this is on Windows, does the script use the .pyw extension to run without console? When you run with the console, do you see output?

Why aren't you using a filedialog?

This doesn't make any sense to me:

1 2 3 4 5 6 7 8

def resource_path(self, relative_path):     """ Get the absolute path to the resource, works for both script and executable. """     try:         base_path = sys._MEIPASS  # PyInstaller stores files here     except Exception:         base_path = os.path.abspath(".")        return os.path.join(base_path, relative_path)

This says "If I am a frozen executable the path is relative to the location of my files. If I am not a frozen executable the path is relative to wherever you started this application." You should use "__file__" instead.

from pathlib import Path   def resource_path(self, relative_path):     """ Get the absolute path to the resource, works for both script and executable. """     return Path(__file__).parent / relative_path

__file__ returns the absolute location of your script. Path(__file__).parent returns the absolute path of the folder containing the script. This works for normal scripts and frozen executables. Path(__file__).parent / relative_path returns the absolute path of relative_path. I think pathlib is much better for manipulating file paths than os. The syntax is cleaner.

Hello,

Thank you for looking into this. I’m running this on Windows 11, 64-bit.

When I set console=True in the .spec file, a console window appears every time the .exe runs, and I can see output in the console. However, when console=False is set in the .spec file, the console does not appear, and the script doesn't run as expected when I execute the .exe.
let me remind you that this works flawlessly when it's run as a .py through Visual Studio Code

I'm not sure if the script uses the .pyw extension to run without a console. Since I only started with Python two weeks ago, how can I check if it's using the .pyw extension or not?

Regarding the script’s output when running with the console, I do see loading and processing messages in the console.

As for using a filedialog, I’m not familiar with how to implement this. any guidance would be appreciated.

I tried updating the code to use Path(__file__).parent / relative_path as suggested, but it did not resolve the issue.

Thanks again for your help!

However, when console=False is set in the .spec file, the console does not appear, and the script doesn't run as expected when I execute the .exe.

Look at --hide-console.
console is enabled but it will automatically hide or minimize the console window.

Not look to much at your code,the other way is to try to write in way so don't need console to be open for it to work.

[deanhystad]

how can I check if it's using the .pyw extension or not?

Does the filename of your script have a .py or .pyw extension? When you double click on a .py file it opens a console window. When you double click on a .pyw file it does not open a console window.

As for using a filedialog, I’m not familiar with how to implement this. any guidance would be appreciated.

Looking at your code again I see that you are using tkinter filedialog.

def select_pdf_directory(self):     # Allow user to select a directory to get subdirectories     folder_path = filedialog.askdirectory(title="Select a Directory Folder")

I tried updating the code to use Path(__file__).parent / relative_path as suggested, but it did not resolve the issue.

I misread the bit in pyinstaller that talked about __file__. __file__ will not work for a .exe. But the resource_path() function is still a little odd.
When running as a script, it uses the current working directory as the base folder. When running the exe it uses the _internals folder. The _internals folder is where pyinstaller puts all the files needed to run the executable. Does your script depend on external files? I don't see resource_path() used anywhere.

I don't think the problem is in the code you posted.

I have tried everything I can think of. What would I need to do to rewrite this so it doesn't need a console?

[deanhystad]

Post the code. All of it. Or at least all the parts related to the pdf merge.

the file is a .py.
This particular script does not depend on any external files however, the GUI depends on .PNG files that I have in there.
