I'm working on an application that uses the matlab engine API for python.
The app works fine, without any issue, therefore I wanted to pack it into a single exe.
At first I had an issue given by mlarray, that I solved by compiling with:
pyinstaller --additional-hook-dir=hooks --onefile main.py
Now on my own computer the .exe file works fine, but as soon as I try to run it on a different machine (with Matlab installed), it gives me the following error:

It seems that it can't find the module "matlabengineforpython3_8", which in theory is in the engine folder in the matlab installation path.
Then it's looking for a file in the wrong place, because the machine doesn't have an F: disk, but my computer does.

I am trying to make an app using pyinstaller. Code is running fine and working, however, when I convert it into exe file it is throwing an error.

enter code hereI have to update an app I made on an Intel MacBook Pro to an Apple Silicon MacBook Pro. I am having problems after build the app file with py2app. I do not know if it also has to do with MacOS Ventura. I am using python 3.9 and have installed PortAudio with Homebrew
It works perfectly if I run it directly from Terminal but if I run the app I get this lines debugging

I have tried to update sounddevice, numpy, portaudio, etc but I am lost as I am not an expert. Any help would be appreciated
I'm trying to make an executable with pyinstaller but it's giving an error in a library I'm using called aspose.words
this is the error that appears to me:
if the image does not open:
Traceback (most recent call last):
File "<frozen importlib._bootstrap>", line 991, in _find_and_load

File "<frozen importlib._bootstrap>", line 626, in _load_backward_compatible
KeyError: 'aspose.pydrawing'
The above exception was the direct cause of the following exception:
ImportError: Unable to import module dependencies. Cannot import the aspose.pydrawing module. The module not found or errors occurred while initializing it.
The above exception was the direct cause of the following exception:

this is the command I used to create the executable:
pyinstaller --noconsole --onefile --collect-binar
ies "aspose" --collect-submodules "aspose" main.py --ico 3151580_game_maze_retro_icon.png
I saw a post here that needed to include aspose with the: --collect-binar command
ies "aspose" --collect-submodules "aspose". but the error continued
Try to use --collect-all option instead of --collect-binaries and --collect-submodules ones: such approach helped me.
i.e., try to use the following command:
pyinstaller --noconsole --onefile --collect-all "aspose" main.py --ico 3151580_game_maze_retro_icon.png
The following error occurs after I have compiled my program and try to run the .exe:

I have tested it on 3 PCs. The results are, that as long as I run my code from VS Code, it works. It also works compiled to .exe for one friend using windows 10.
It does not work on my Windows 11 PC and also not on my second Laptop which is running Windows 10 also.
There was never any issue like that before and I can't understand whats going on

I suspect that the error has something to do with swig, but I am unsure what to do to resolve it. Also It looks like is an error about may be caused by binary compiled for 64-bit linux, on a 32-bit installation, but I don’t know how to fix that issue. Any help would be greatly appreciated.
Thanks
ImportError: /home/chip/.local/lib/python3.5/site-packages/tabu/_tabu_search.so: wrong ELF class: ELFCLASS64
This error means: you are trying to load a 64-bit _tabu_search.so library into a 32-bit process. You must either use 64-bit python, or install a 32-bit version of the tabu_search package.
I suspect that the error has something to do with swig
No, SWIG has almost nothing to do with your problem.
