How to create exe of project who has .cxx .py file and many dlls

I have a code who is depended on Qt, PyQt, VTK, ITK, libs.
using CMAKE to build
Environment : Windows
I want to distribute EXE who has cxx, py files and related dlls
I have tried to compile and got executable but my python files are remaining necked.
I don't want to share python files as a script.
how we can make those python files as a dlls

python is often a hard language to turn to exe but the best way to do so is using the pyinstaller package. Installed by pip install pyinstaller and can turn a .py file to a .exe by pyinstaller --onefile FILENAME.py in CMD. After that your exe file should be stored in a folder called disk. The other files can just be included in the same file as the exe.

How to convert a python script .py file into an exe without embedding python interpreter in it

My requirement is to deploy a python script in a form of exe with digital signature but the python interpreter and dependent python modules should not be embedded into the exe. Rather, python needs to be explicitly installed on the server.
I have tried pyinstaller and cx_freeze but both embeds python and related modules along with the script codebase into the exe. We need to decouple python and script codebase.

You can use py2exe and use Cython to convert your key .py files in .pyc, C compiled files, like .dll in Windows and .so on Linux.
Alternatively, you can use PyInstaller to package Python programs as standalone executables. It works on Windows, Linux, and Mac.

Python/C API project - compile to exe

I'm working on project where I am using Python/C API and C++. C++ is used for most part of application, mainly for gui (wxWidgets), while Python is used for calculations on large data sets, e.g. from files. I'm doing it in Visual Studio and when I run the project in IDE everything works fine, like I want it to. Also, the exe file that is created during the launch of the project in the visual studio, when it is in the same folder with the python .py file, also works as it should be. But what I want to achieve is a complete application contained in one exe.
While searching for a solution, I found various possibilities to create an exe from a python file. For example, PyInstaller which I tested for a simple "hello world" python file and it works. However, I don't know and can't find a solution how to combine the exe created in visual with a python file.
In PyInstaller github issues I found that line:
pyinstaller App.py --add-data 'pathtoexe\your.exe;.' --add-binary "pathtodll\your.dll;." --onefile --noconsole --clean
And I typed this into the console:
pyinstaller myPythonFile.py --add-data 'myVisualGeneratedFile.exe;.' --onefile --noconsole --clean
But after that, when I clicked generated exe file, nothing happens.
I hope that someone has done a similar thing before and I can find help here because I'm already losing my mind on it.

According to https://pyinstaller.readthedocs.io/en/stable/usage.html, you should use --add-binary and not --add-data.

PyInstaller: Can't find .so module when exe is executed

A python script uses a .so file.
I made an exe for this python script using PyInstaller.
But when I execute the generated exe, it is unable to locate this .so file
So how to link this .so to a python code that will get converted to a .exe
Note: when running the .py program, if I set the location of .so in LD_LIBRARY_PATH, it executes the program correctly but once I make the exe using
pyinstaller script.py --onefile
(with .so in the same directory), it doesnt find the .so file..
Thank you in advance

You need to make sure that your . so file is in your system library path as well as your python library path. Setting your LD path is a quick fix. PyInstaller will need it in your system path. Depending on your Windows version it's Environment variables>PATH.

Do I need Python installed if I have PYC files?

I want to add Python as a scripting language to my game. If instead of distributing PY script, I distribute the PYC compiled files with my game, will the user still need Python installed, or will the DLL be sufficient?

Not only would they still need the Python interpreter, but the compiled python byte-code files are not guaranteed to work across different platforms.

You do need an executable to actually load the files into the VM. Fortunately it doesn't need to be very complex.

pyinstaller can be used to convert the .py file into an executable file
to install the pyinstaller
pip install pyinstaller
and to convert the .py file let's say file.py
pyinstaller file.py
this will make two new folders in the same directory
build and dist. dist folder contains all the required dll and file.exe to run the python code without python installed.
