Create a single executable from a Python project [closed]
(3 answers)
Closed 1 year ago.
I'm building a Python application and don't want to force my clients to install Python and modules.
So, is there a way to compile a Python script to be a standalone executable?
You can use PyInstaller to package Python programs as standalone executables. It works on Windows, Linux, and Mac.
PyInstaller Quickstart
Install PyInstaller from PyPI:
pip install pyinstaller
Go to your program’s directory and run:
pyinstaller yourprogram.py
This will generate the bundle in a subdirectory called dist.
pyinstaller -F yourprogram.py
Adding -F (or --onefile) parameter will pack everything into single "exe".
pyinstaller -F --paths=<your_path>\Lib\site-packages yourprogram.py
running into "ImportError" you might consider side-packages.
pip install pynput==1.6.8
still runing in Import-Erorr - try to downgrade pyinstaller - see Getting error when using pynput with pyinstaller
For a more detailed walkthrough, see the manual.
You can use py2exe as already answered and use Cython to convert your key .py files in .pyc, C compiled files, like .dll in Windows and .so on Linux.
It is much harder to revert than common .pyo and .pyc files (and also gain in performance!).
You might wish to investigate Nuitka. It takes Python source code and converts it in to C++ API calls. Then it compiles into an executable binary (ELF on Linux). It has been around for a few years now and supports a wide range of Python versions.
You will probably also get a performance improvement if you use it. It is recommended.
Yes, it is possible to compile Python scripts into standalone executables.
PyInstaller can be used to convert Python programs into stand-alone executables, under Windows, Linux, Mac OS X, FreeBSD, Solaris, and AIX. It is one of the recommended converters.
py2exe converts Python scripts into only executable on the Windows platform.
Cython is a static compiler for both the Python programming language and the extended Cython programming language.
I would like to compile some useful information about creating standalone files on Windows using Python 2.7.
I have used py2exe and it works, but I had some problems.
It has shown some problems for creating single files in Windows 64 bits: Using bundle_files = 1 with py2exe is not working;
It is necessary to create a setup.py file for it to work. http://www.py2exe.org/index.cgi/Tutorial#Step2;
I have had problems with dependencies that you have to solve by importing packages in the setup file;
I was not able to make it work together with PyQt.
This last reason made me try PyInstaller http://www.pyinstaller.org/.
In my opinion, it is much better because:
It is easier to use.
I suggest creating a .bat file with the following lines for example (pyinstaller.exe must be in in the Windows path):
pyinstaller.exe --onefile MyCode.py
You can create a single file, among other options (https://pyinstaller.readthedocs.io/en/stable/usage.html#options).
I had only one problem using PyInstaller and multiprocessing package that was solved by using this recipe: https://github.com/pyinstaller/pyinstaller/wiki/Recipe-Multiprocessing.
So, I think that, at least for python 2.7, a better and simpler option is PyInstaller.
And a third option is cx_Freeze, which is cross-platform.
pyinstaller yourfile.py -F --onefile
This creates a standalone EXE file on Windows.
Important note 1: The EXE file will be generated in a folder named 'dist'.
Important note 2: Do not forget --onefile flag
You can install PyInstaller using pip install PyInstaller
NOTE: In rare cases there are hidden dependencies...so if you run the EXE file and get missing library error (win32timezone in the example below) then use something like this:
pyinstaller --hiddenimport win32timezone -F "Backup Program.py"
I like PyInstaller - especially the "windowed" variant:
pyinstaller --onefile --windowed myscript.py
It will create one single *.exe file in a distination/folder.
You may like py2exe. You'll also find information in there for doing it on Linux.
Use py2exe.... use the below set up files:
from distutils.core import setup
import py2exe
from distutils.filelist import findall
import matplotlib
setup(
console = ['PlotMemInfo.py'],
options = {
'py2exe': {
'packages': ['matplotlib'],
'dll_excludes': ['libgdk-win32-2.0-0.dll',
'libgobject-2.0-0.dll',
'libgdk_pixbuf-2.0-0.dll']
}
},
data_files = matplotlib.get_py2exe_datafiles()
)
I also recommend PyInstaller for better backward compatibility such as Python 2.3 - 2.7.
For py2exe, you have to have Python 2.6.
For Python 3.2 scripts, the only choice is cx_Freeze. Build it from sources; otherwise it won't work.
For Python 2.x I suggest PyInstaller as it can package a Python program in a single executable, unlike cx_Freeze which outputs also libraries.
Since it seems to be missing from the current list of answers, I think it is worth mentioning that the standard library includes a zipapp module that can be used for this purpose. Its basic usage is just compressing a bunch of Python files into a zip file with extension .pyz than can be directly executed as python myapp.pyz, but you can also make a self-contained package from a requirements.txt file:
$ python -m pip install -r requirements.txt --target myapp
$ python -m zipapp -p "interpreter" myapp
Where interpreter can be something like /usr/bin/env python (see Specifying the Interpreter).
Usually, the generated .pyz / .pyzw file should be executable, in Unix because it gets marked as such and in Windows because Python installation usually registers those extensions. However, it is relatively easy to make a Windows executable that should work as long as the user has python3.dll in the path.
If you don't want to require the end user to install Python, you can distribute the application along with the embeddable Python package.
py2exe will make the EXE file you want, but you need to have the same version of MSVCR90.dll on the machine you're going to use your new EXE file.
See Tutorial for more information.
You can find the list of distribution utilities listed at Distribution Utilities.
I use bbfreeze and it has been working very well (yet to have Python 3 support though).
Not exactly a packaging of the Python code, but there is now also Grumpy from Google, which transpiles the code to Go.
It doesn't support the Python C API, so it may not work for all projects.
Using PyInstaller, I found a better method using shortcut to the .exe rather than making --onefile. Anyway, there are probably some data files around and if you're running a site-based app then your program depends on HTML, JavaScript, and CSS files too. There isn't any point in moving all these files somewhere... Instead what if we move the working path up?
Make a shortcut to the EXE file, move it at top and set the target and start-in paths as specified, to have relative paths going to dist\folder:
Target: %windir%\system32\cmd.exe /c start dist\web_wrapper\web_wrapper.exe
Start in: "%windir%\system32\cmd.exe /c start dist\web_wrapper\"
We can rename the shortcut to anything, so renaming to "GTFS-Manager".
Now when I double-click the shortcut, it's as if I python-ran the file! I found this approach better than the --onefile one as:
In onefile's case, there's a problem with a .dll missing for the Windows 7 OS which needs some prior installation, etc. Yawn. With the usual build with multiple files, no such issues.
All the files that my Python script uses (it's deploying a tornado web server and needs a whole freakin' website worth of files to be there!) don't need to be moved anywhere: I simply create the shortcut at top.
I can actually use this exact same folder on Ubuntu (run python3 myfile.py) and Windows (double-click the shortcut).
I don't need to bother with the overly complicated hacking of .spec file to include data files, etc.
Oh, remember to delete off the build folder after building. It will save on size.
Use Cython to convert to C, compile, and link with GCC.
Another could be, make the core functions in C (the ones you want to make hard to reverse), compile them and use Boost.Python to import the compiled code (plus you get a much faster code execution). Then use any tool mentioned to distribute.
I'm told that PyRun is also an option. It currently supports Linux, FreeBSD and Mac OS X.

How can I create a Python executable program that doesn't force the user to actually download Python libraries and that stuff in order to be executed?
Let's say that I already built a program that essentially takes some images from an user's path and make new ones using the following libraries/modules: os itertools pandas PIL What I need now is to make that program become an executable file that can be actually executed without having to have installed the Python environment and the libraries used in the code, because the user would not know how to code, and would not likely matter how the code works. The program would run on Windows OS (PC) only , and would use the cmd.exe as the interpreter and medium for user inputs and results display.
Solved here You can use wheel, and ship whole environment. #Vincent Caeles: "#rh979 a wheel is not meant to have all dependencies. Subsequently you could do pip install path/to/wheel.whl --target /path/to/some/folder and zip the contents of the 'folder' to have all your dependencies in the zip archive and ship that to the environment where you want to run your code.

How to simply compile a big python program with huge number of files, for linux, mac and windows [duplicate]
I'm trying to convert a fairly simple Python program to an executable and couldn't find what I was looking for, so I have a few questions (I'm running Python 3.6): The methods of doing this that I have found so far are as follows downloading an old version of Python and using pyinstaller/py2exe setting up a virtual environment in Python 3.6 that will allow me to do 1. downloading a Python to C++ converter and using that. Here is what I've tried/what problems I've run into. I installed pyinstaller before the required download before it (pypi-something) so it did not work. After downloading the prerequisite file, pyinstaller still does not recognize it. If I'm setting up a virtualenv in Python 2.7, do I actually need to have Python 2.7 installed? similarly, the only python to C++ converters I see work only up until Python 3.5 - do I need to download and use this version if attempting this?
Steps to convert .py to .exe in Python 3.6
Install Python 3.6.
Install cx_Freeze, (open your command prompt and type pip install cx_Freeze.
Install idna, (open your command prompt and type pip install idna.
Write a .py program named myfirstprog.py.
Create a new python file named setup.py on the current directory of your script.
In the setup.py file, copy the code below and save it.
With shift pressed right click on the same directory, so you are able to open a command prompt window.
In the prompt, type python setup.py build
If your script is error free, then there will be no problem on creating application.
Check the newly created folder build. It has another folder in it. Within that folder you can find your application. Run it. Make yourself happy.
See the original script in my blog.
setup.py:
from cx_Freeze import setup, Executable
base = None
executables = [Executable("myfirstprog.py", base=base)]
packages = ["idna"]
options = {
'build_exe': {
'packages':packages,
},
}
setup(
name = "<any name>",
options = options,
version = "<any number>",
description = '<any description>',
executables = executables
)
EDIT:
be sure that instead of myfirstprog.py you should put your .pyextension file name as created in step 4;
you should include each imported package in your .py into packages list (ex: packages = ["idna", "os","sys"])
any name, any number, any description in setup.py file should not remain the same, you should change it accordingly (ex:name = "<first_ever>", version = "0.11", description = '' )
the imported packages must be installed before you start step 8.
Python 3.6 is supported by PyInstaller. Open a cmd window in your Python folder (open a command window and use cd or while holding shift, right click it on Windows Explorer and choose 'Open command window here'). Then just enter pip install pyinstaller And that's it. The simplest way to use it is by entering on your command prompt pyinstaller file_name.py For more details on how to use it, take a look at this question.
There is an open source project called auto-py-to-exe on GitHub. Actually it also just uses PyInstaller internally but since it is has a simple GUI that controls PyInstaller it may be a comfortable alternative. It can also output a standalone file in contrast to other solutions. They also provide a video showing how to set it up. GUI: Output: Alternatively use pyinstaller directly: pip install pyinstaller pyinstaller filename
I can't tell you what's best, but a tool I have used with success in the past was cx_Freeze. They recently updated (on Jan. 7, '17) to version 5.0.1 and it supports Python 3.6. Here's the pypi https://pypi.python.org/pypi/cx_Freeze The documentation shows that there is more than one way to do it, depending on your needs. http://cx-freeze.readthedocs.io/en/latest/overview.html I have not tried it out yet, so I'm going to point to a post where the simple way of doing it was discussed. Some things may or may not have changed though. How do I use cx_freeze?
Now you can convert it by using PyInstaller. It works with even Python 3. Steps: Fire up your PC Open command prompt Enter command pip install pyinstaller When it is installed, use the command 'cd' to go to the working directory. Run command pyinstaller <filename>
I've been using Nuitka and PyInstaller with my package, PySimpleGUI. Nuitka There were issues getting tkinter to compile with Nuikta. One of the project contributors developed a script that fixed the problem. If you're not using tkinter it may "just work" for you. If you are using tkinter say so and I'll try to get the script and instructions published. PyInstaller I'm running 3.6 and PyInstaller is working great! The command I use to create my exe file is: pyinstaller -wF myfile.py The -wF will create a single EXE file. Because all of my programs have a GUI and I do not want to command window to show, the -w option will hide the command window. This is as close to getting what looks like a Winforms program to run that was written in Python. [Update 20-Jul-2019] There is PySimpleGUI GUI based solution that uses PyInstaller. It uses PySimpleGUI. It's called pysimplegui-exemaker and can be pip installed. pip install PySimpleGUI-exemaker To run it after installing: python -m pysimplegui-exemaker.pysimplegui-exemaker
The best and easiest way is auto-py-to-exe for sure, and I have given all the steps and red flags below which will take you just 5 mins to get a final .exe file as you don't have to learn anything to use it. 1.) It may not work for python 3.9 on some devices I guess. 2.) While installing python, if you had selected 'add python 3.x to path', open command prompt from start menu and you will have to type pip install auto-py-to-exe to install it. You will have to press enter on command prompt to get the result of the line that you are typing. 3.) Once it is installed, on command prompt itself, you can simply type just auto-py-to-exe to open it. It will open a new window. It may take up to a minute the first time. Also, closing command prompt will close auto-py-to-exe also so don't close it till you have your .exe file ready. 4.) There will be buttons for everything you need to make a .exe file and the screenshot of it is shared below. Also, for the icon, you need a .ico file instead of an image so to convert it, you can use https://convertio.co/ 5.) If your script uses external files, you can add them through auto-py-to-exe and in the script, you will have to do some changes to their path. First, you have to write import sys if not written already, second, you have to make a variable for eg, location=getattr(sys,"_MEIPASS",".")+"/", third, the location of example.png would be location+"/example.png" if it is not in any folder. 6.) If it is showing any error, it may probably be because of a module called setuptools not being at the latest version. To upgrade it to the latest version, on command prompt, you will have to write pip install --upgrade setuptools. Also, in the script, writing import setuptools may help. If the version of setuptools is more than 50.0.0 then everything should be fine. 7.) After all these steps, in auto-py-to-exe, when the conversion is complete, the .exe file will be in the folder that you would have chosen (by default, it is 'c:/users/name/output') or it would have been removed by your antivirus if you have one. Every antivirus has different methods to restore a file so just experiment if you don't know. Here is how the simple GUI of auto-py-to-exe can be used to make a .exe file.
PyOxidizer can be an option here. It's pretty popular with 3.3k stars on Github. Its documentation says PyOxidizer is capable of producing a single file executable - with a copy of Python and all its dependencies statically linked and all resources (like .pyc files) embedded in the executable. You can copy a single executable file to another machine and run a Python application contained within. It just works. While I'm not sure if it is capable of producing .exe file PyOxidizer definitely helps with packaging and distribution.
Converting .py to .exe with pandas imported for all users not having pandas
I'm new to Python, but I have set up an python script for searching some specific Values in 2 different excel sheets printing out matches (in excel).
Problem is, that our work machines are heavily locked down and without admin privileges, we can't really install anything (we can download though). Is there any version of Python that is Windows 7 compatible that will run standalone without requiring any sort of installer?
I have tried pyInstaller, but the problem is that in my script we need PANDAS.
And there is no possibility to pip install pandas to our local machines. All is blocked. ("pip install pandas" is not possible. I did the code with Anaconda)
So my question is: how can I set up a file for my coworkers, who have no permission to download pandas?
Can I set up an exe file (all use windows 7/10) in my private computer where pandas is already installed and forward it to the workers?
It should be very easy for them to use--> double click for executing the python script
Thanks in advance for any advice.
You can also use pyinstaller which personally I find the easiest to use. It can bundle executables for both Linux and Windows, but it must be run on that architecture that you wish to have executable for, i.e. if you want to have Linux executable the pyinstaller command with your code must be run on Linux OS of some kind. More here: https://www.pyinstaller.org/
This is old so you may already have found a solution but this might help others. Python by default is an interpreted language. This means that compiling it into an .exe file is impossible. However, using some modules it is indeed possible to convert a .py script into a windows executable. You can try py2exe. py2exe is a Python Distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation. They have a tutorial here.
How to convert file .py to .exe, having Python from Anaconda Navigator? (in which command prompt should I write installation codes?)
I created a Python script (format .py) that works. I would like to convert this file to .exe, to use it in a computer without having Python installed. How can I do? I have Python from Anaconda3. What can I do? Thank you! I followed some instruction found here on Stackoverflow. .I modify the Path in the 'Environment variables' in the windows settings, edited to the Anaconda folder. .I managed to install pip in conda prompt (I guess). Still, nothing is working. I don't know how to proceed and in general how to do things properly.
I personaly use pyinstaller, its available from pip. But it will not really compile, it will just bundle. The difference is compiling means translating to real machine code while bundling is creating a big exe file with all your libs and your python interpreter. Even if pyinstaller create bigger file and is slower than cython (at execution), I prefer it because it work all the time without work (except lunching it).
How do I distribute my Python 3.6 application with all dependencies like in SqueezeTool
I have a python application that I built on Kivy for the GUI, and I separated that file from the RNN model. I just import that file directly with: from keras_network import Network I tried using the official trick to deploying using pyinstaller, but that doesn't work, as my application crashes, when running the final .exe file generated. I even made appropriate changes to the .spec file. Isn't there an easier way to package this application in Python 3.6? (like SqueezeTool, which is too old, and isn't working in Python 3.6) Can I compile the python files to .pyc files and have all dependencies statically linked? And why is this still such a big pain, when Python is so popular?
Ok... I finally got it to work. I came up with this solution after I implemented the whole project in PyQt5, and while trying to package it with PyInstaller. Here is how I got it to work (for people who could have any problems later): Used python 3.5 Install Windows 10 SDK for some missing files that should've been with MSVC 2015. Install the dev version PyInstaller from: pip install https://github.com/pyinstaller/pyinstaller/archive/develop.zip --upgrade Used the command to include my data files, as well as including hidden import h5py: pyinstaller --add-data keras_model.h5;. --add-data TrainingData.txt;. --hidden-import=h5py --hidden-import=h5py.defs --hidden-import=h5py.utils --hidden-import=h5py.h5ac --hidden-import=h5py._proxy project-name.py Then edited the .spec file generated. Added "from kivy.deps import sdl2, glew" without the quotes in the beginning of the file after the comment. Also added "*[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)]," without the quotes in the COLLECT() function call as the 6th argument. Then used the following command to rebuild using .spec file: pyinstaller --add-data keras_model.h5;. --add-data TrainingData.txt;. --hidden-import=h5py --hidden-import=h5py.defs --hidden-import=h5py.utils --hidden-import=h5py.h5ac --hidden-import=h5py._proxy project-name.spec Then the built application's executable was present in the 'dist\project-name\' directory. Double clicking the application lead to the application executing perfectly. Hope this helps anyone stuck in the same place.
