Freeze your script with Pyinstaller

[masoudr]

Hi,
You might want to freeze your script into a standalone executable to run on any system without the need of installing python or face_recognition and maybe you want to create a demo for your application and want to give it to someone else without giving your source code. Here is a simple tutorial to do that. I tested this method with python3.6 on Windows 10, but I think you can get it working on Linux with a similar method.

1. Make sure you have correctly installed both face_recognition and dlib and you see no error when importing them into your script.
2. Make sure your script works fine, and all its dependencies are right next to it, and you can run it fine with python yourscript.py.
3. Install Pyinstaller with pip:
   pip install pyinstaller
4. Create a new directory and move your python script and all dependencies into it. I call it myproject and myscript.py
5. Copy face_recognition_models and scipy-extra-dll from your python installed directory to your project directory.
6. Create an empty file called <yourscriptname>.spec like myscript.spec next to your python script.
7. Use below Pyinstaller spec file sample and edit some parts according to your needs: (I mark it with <> tag)

# -*- mode: python -*-

block_cipher = None

face_models = [
('.\\face_recognition_models\\models\\dlib_face_recognition_resnet_model_v1.dat', './face_recognition_models/models'),
('.\\face_recognition_models\\models\\mmod_human_face_detector.dat', './face_recognition_models/models'),
('.\\face_recognition_models\\models\\shape_predictor_5_face_landmarks.dat', './face_recognition_models/models'),
('.\\face_recognition_models\\models\\shape_predictor_68_face_landmarks.dat', './face_recognition_models/models'),
]

a = Analysis(['<your python script name.py>'],
             pathex=['<path to working directory>'],
             binaries=face_models,
             datas=[],
             hiddenimports=['scipy._lib.messagestream', 'scipy', 'scipy.signal', 'scipy.signal.bsplines', 'scipy.special', 'scipy.special._ufuncs_cxx',

             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)

a.datas += Tree('./scipy-extra-dll', prefix=None)

pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          name='<your python script name>',
          debug=False,
          strip=False,
          upx=True,
          runtime_tmpdir=None,
          console=True )

8. Generate your executable with python -m pyinstaller myscript.spec
9. If you see no error then your executable can be found in dist directory.
10. Enjoy!

Thanks to @ageitgey and @davisking for their awesome work.

Cool, thanks for sharing!

I found this worked very well when running on Windows desktop, but the application would crash on Windows Server 2012 - 2016 with an unhelpful, vague unable to execute DLL error. I found this issue was caused by using the latest version of dlib linked in the project install guide under issue 175 (currently 19.9.99). However, by using 'pip install dlib', which installs 19.9.0 (again, currently as of writing this). The frozen executable is running without errors on both desktop and server. I've also been testing freezing this in both 32-bit and 64-bit python and both are working. Thanks

[masoudr]

@vgreis I haven't tested Pyinstaller with the new version of dlib but I think you can get it working by just add the missing DLL's to binaries it will then be extracted when running the app and again remember that it doesn't matter if you install dlib by source or pip, just make sure your installation is successful.

[mariocesarc]

Thanks! It works

[inewlife]

Incompatible library version: dlib.so requires version 51.0.0 or later, but libpng16.16.dylib provides version 38.0.0

[masoudr]

@inewlife Can you post the complete error log? I haven't tested this method with the new version of dlib but I think it is not related because what you need here is just adding scipy and face_recognition_modules manually not the dlib itself.

[fordffx]

I did as what the first floor told,but still got this:

how did the exe file come to this dir ?
and _MEI71042 changes every time the exe file run

when i use nuitka to make exe file ,and it jumped out this as the exe file run :
Please install face_recognition_models with this command before using face_recognition:
pip install git+https://github.com/ageitgey/face_recognition_models
actruly, I did installed them successfully.

thanks

[masoudr]

@fordffx Hi,
As I said in the first post you must first install all dependencies for your python. About the _MEI71042, every time you run the executable pyinstaller tries to extract dependencies in the temp directory and when your program ends without exception it deletes that folder automatically,

[fordffx]

i replaced
datas=[]
with
datas=[('shape_predictor_68_face_landmarks.dat','./face_recognition_models/models'),('shape_predictor_5_face_landmarks.dat','./face_recognition_models/models'),('mmod_human_face_detector.dat','./face_recognition_models/models'),('dlib_face_recognition_resnet_model_v1.dat','./face_recognition_models/models')]
that works,thanks

[roiksail]

thanks for sharing your knowledge...i can't find scipy-extra-dll ...how i can to find them in python directory??i am in ubuntu 16.04,
thank you in advance

[masoudr]

@roiksail Hi, dll files are not made for Linux systems so you can't find any. I think you don't need to add scipy dependencies. Just build your binary file and try to run it. If It complains about some files just find that and add it manually like above method. That is it.

[roiksail]

thank you,how i change myscript.spec file??

@roiksail First you need to freeze your script with pyinstaller script.py then the spec file should be generated next to your script file.

[roiksail]

thank you so much,i mmaked executable application in ubuntu but when i copied this file in ubuntu then it was simply file and it does not executed,how i fix this??

[masoudr]

@roiksail I think you need to find out what is Pyinstaller and how to use it in from here. In general, after you run the command you should find the executable with the exact name of the script. I think Pyinstaller will make the file as executable binary so you can just use ./yourscriptname command and if it didn't work try to make it executable with sudo chmod +x yourscriptname. That is it.

[sincerefly]

@vgreis thanks, when I build use dlib from github source code, The version is 19.10.99, It can only run on x64 system, and when I use pip install dlib, the version is 19.10.0, It can run on x86 system

[sincerefly]

@masoudr

I'm not find scipy-extra-dll in my site-packages, should I need install scipy?

1, when I am not install scipy, I can run face_recognition, Is scipy necessary?
2, I install scipy, and copy scipy dir from site-packages to project dir, with a.datas += Tree('./scipy-extra-dll', prefix=None), I can't find scipy-extra-dll, but I find extra-dll in scipy dir, can I write scipy/extra-dll instead it or not

thank you

[masoudr]

@sincerefly Hi, If I remember correctly there are some examples that need scipy so if you are using scipy with your project you need those files but if you don't, just use face_models no need for hidden imports that is it. And remember you just need to first freeze your script normally and if you got any errors about missing packages, you need to feed them manually in your spec file.

[ratijas]

@sincerefly @masoudr Confirmed. My app works with face_recognition without touching scipy at all. No hidden_imports nor datas needed in this case.

Also, for now face_recognition_models/**/*.dat resources get copied automatically without any extra code in .spec file.

Thanks for your efforts!

[tinshade]

@masoudr Can you please explain to me how can I get the face_recognition_models/**/*.dat resources added from the .spec file? It does not seem to work for me. It says unable to open shape_predictor_68_face_landmarks.dat for some reason.

So far, I have tried:

• Creating with --onedir

• Adding the files to the directory and then running pyinstaller with --onedir.

[masoudr]

@tinshade I've already added all 4 model files in the example above, you just need to use the above sample spec file and fill parameters and this should solve your problem. But if you still need to add other models you can just add this to your spec file.

a = Analysis(...
     datas= [ ('face_recognition_models/**/*.dat', './face_recognition_models/models' ) ],
     ...
     )

[masoudr]

@alexpardede I'm not familiar with Conda but I would suggest you first check your naming, it is case sensitive (python -m PyInstaller). Second, you can check your installed modules with pip freeze. Also if you have any problem with installing PyInstaller you should ask in its repo.

[zkywalker]

can you help me for this error ? i already have face-recognition-models while i check with pip freeze. and i already create and execute the attendance.spec. please help me. Thank You

try to copy the dependencies that open fail to your output dependencies dir, its helpful for me

[zkywalker]

i have new issue. my main script refere to a other script. and the script call library "frozen_inference_graph_face.pb" from another folder. can you help me to solve the problem ?
thank for your attention.

lol, the solution is same to dependencies no find, just copy them to the output dependencies dir. And its helpful when you do not use the -f arg, which will generate a file with all dependencies in it.

sorry to bother you.I don't understand.is 19.9.0dlib installed in the computer which pyinstaller the file or in winserver2012?My my application can run in my windows computer,but it can't work on my windows server2012.And my dlib package can't be uninstalled completely now....

maybe you could try building the latest version of dlib on the target platform

[rageshhub]

I can't find the scipy-extra-dll in windows although I installed scipy. Help me.

[masoudr]

@Ragesh77 I haven't tested the new version. But check if you can import scipy without any problem and then double-check the file existence. If you still can't find it skip it and check if the executable works or not.

@masoudr Thanks for answering. I downgraded scipy to 1.3.0 and could locate all the files.

[HAKANMAZI]

I can't find the scipy-extra-dll in windows although I installed scipy. Help me.

You can search extra-dll using below code on cmd
dir extra-dll /s /p
I hope you will find it in scipy directory. After create scipy-extra-dll directory.
Then all dll files transfer to scipy-extra-dll directory.

Thanks for everything all guys. I did what you said and I created an exe file successfully. But when I click exe file it's working only once then suddenly closes. Before close it says something but I don't read because it is so fastly close. How can I fix this problem

[masoudr]

@HAKANMAZI Try to run executable with CMD and you should get the error in the console. Then put the error.

@Ragesh77 It is not an app. But if you trying to deploy your app with docker you can follow this.

Finally I solved my problem.
As I said I don't use sklearn on my code but background sklearn was using. Then I add in hiddenimports=['sklearn','sklearn.neighbors._typedefs','sklearn.utils._cython_blas'] in my spec file.
and it is okey, it solved :)

[daynial132]

hello I am new to this freezer part,

I have made a separate folder as mentioned and move my python script and models in it.
also i copied the freezer script(.spec) file. finally i got the build giving the error "ImportError: No module named 'face_recognition'"
Please help me with it I am using anaconda, and not using scipy.
I have attached the freezer script also.

freeze_app .txt

[masoudr]

@daynial132 First make sure that your script is working fine in your environment also you must be sure that you run PyInstaller from your environment (with using python -m PyInstaller). I think you are running the PyInstaller from your main Python installation which doesn't have face_recognition.

[daynial132]

@masoudr I have placed my python script,3 pics and the freezer file (.spec) and the face_recognition_models in the folder only. do I need any thing else?

I have check my python script to run on my anaconda shell, it is running fine that's mean dlib and face_recognition lib is installed properly. Am i right or missing some thing?

Also I have used anaconda shell to run (python -m PyInstaller) command.

Thank you for your reply

[masoudr]

@daynial132 I haven't tested this with Conda yet, but I don't think it would be a problem. Your error means that PyInstaller can't find the face_recognition. Try to run pip freeze inside your console and make sure that face_recognition exists in the output. If it is there but you still get that error try to add face_recognition into the hidden_imports as I did for the scipy modules.

@mend4x Make sure that you have the shape_predictor_68_face_landmarks.dat when building the project. Also if the error came double check that the shape_predictor_68_face_landmarks.dat exists in the given path (e.g /tmp/_MEIHAOamS/face_recognition_models/models).

[mend4x]

@masoudr I actually do have this file in script directory. The given path is tmp so each time it runs it's new directory

[masoudr]

@mend4x Double check that the files in models directory and also when you run the script check the tmp directory and verify the file and its size.

@masoudr 我的问题是，打包的时候没有问题，打包后，点击exe 只有小黑窗口，程序没办法运行。
界面没办法显示。请教您帮忙

Error loading Python DLL 'C:\Users\91880\Desktop\application\python310.dll'. getting this error please help.

[masoudr]

@divyangana009 This is a basic error that I think might be related to PyInstaller itself. Have you tried freezing a simple script, I mean without face_recognition, and see if the executable can be run? Also, try to create a virtual environment and install the latest version of PyInstaller with pip install -U PyInstaller.

I've tried out what you suggested and my program runs with no errors in VSC but every time I convert it to .exe it simply runs so quickly that the terminal pops up so quick and close. I tried executing the exe file in Anaconda prompt and still giving me this error:

SyntaxError: Non-UTF-8 code starting with '\x90' in file C:\Users\PC\Desktop\VSworkSpace\FaceRecProject\dist\main\main.exe on line 1, but no encoding declared; see https://python.org/dev/peps/pep-0263/ for details

Even though I've added # -- coding: utf-8 -- at the first line of my code

Please help me solving this issue

[masoudr]

@SAUDIANO I'm not sure what is the cause of the problem, but first, make sure that you run your executable directly from a standard CMD and not python this. Second, create a clean virtual environment with Conda and generate the executable in that env. Moreover, try to update the Pyinstaller to the latest version.

Hi, You might want to freeze your script into a standalone executable to run on any system without the need of installing python or face_recognition and maybe you want to create a demo for your application and want to give it to someone else without giving your source code. Here is a simple tutorial to do that. I tested this method with python3.6 on Windows 10, but I think you can get it working on Linux with a similar method.

1. Make sure you have correctly installed both face_recognition and dlib and you see no error when importing them into your script.
2. Make sure your script works fine, and all its dependencies are right next to it, and you can run it fine with python yourscript.py.
3. Install Pyinstaller with pip:
   pip install pyinstaller
4. Create a new directory and move your python script and all dependencies into it. I call it myproject and myscript.py
5. Copy face_recognition_models and scipy-extra-dll from your python installed directory to your project directory.
6. Create an empty file called <yourscriptname>.spec like myscript.spec next to your python script.
7. Use below Pyinstaller spec file sample and edit some parts according to your needs: (I mark it with <> tag)

8. Generate your executable with python -m pyinstaller myscript.spec
9. If you see no error then your executable can be found in dist directory.
10. Enjoy!

Thanks to @ageitgey and @davisking for their awesome work.

i use ultralytics then how to use
