Windows Installation Tutorial #175

masoudr · 2017-09-14T12:59:14Z

Hi,
I've successfully installed and tested this tool on my Windows 10 machine and I'm writing a simple procedure to install it. It may be useful for some people to try to use this tool on a Windows machine.

IMPORTANT: Actually this project has made for Linux systems and especially dlib. In my tests, the performance of this tool in Windows 10 was about a quarter in comparison with Ubuntu built with the same specs. But I haven't seen any difference between these two in other subjects.

Read First:
The new version of dlib doesn't need Boost anymore so you can skip it. Remember that you still need to meet the following requirements.
Requirments:
(I've used this tutorial with these tools installed on Windows 10 but the newer versions may work too.)

Microsoft Visual Studio 2015 (or newer) with C/C++ Compiler installed. (Visual C++ 2015 Build Tools didn't work for me and I got into problems in compiling dlib)
Of course Python3 (I used Python3.5 x64 but the other versions may work too)
CMake for windows and add it to your system environment variables.
(ONLY FOR older versions of dlib) Boost library version 1.63 or newer. Also, you can use precompiled binaries for specific MSVC you have but I don't suggest. (I've included the compiling procedure of Boost in this tutorial)

Installation:
Easy installation:
Just install dlib and face_recognition (not always on the newest version):
pip install dlib and then pip install face_recognition.

Manual installation:

Download and install scipy and numpy+mkl (must be mkl version) packages from this link (all credits goes to Christoph Gohlke). Remember to grab the correct version based on your current Python version.
Download Boost library source code or binary release for your current MSVC from this link.
If you downloaded the binary version skip to step 4 else follow these steps to compile and build Boost by yourself:
3-1. Extract the Boost source files into C:\local\boost_1_XX_X (X means the current version of Boost you have)
3-2. Create a system variable with these parameters:
Name: VS140COMNTOOLS
Value: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\ (or any path where you have installed MSVC)
3-3. Open Developer Command Prompt for Visual Studio and go to the current directory of Boost extracted and try these commands to compile Boost:
bootstrap
b2 -a --with-python address-model=64 toolset=msvc runtime-link=static
3-4. If you successfully compile Boost, it should create compiled files in stage directory.
(If you have already compiled Boost skip this step) If you already download the binary release just extract the contents to C:\local\boost_1_XX_X
Grab latest version of dlib from this repo and extract it.
Go to dlib directory and open cmd and follow these commands to build dlib: (remember to replace XX with the current version of Boost you have)
set BOOST_ROOT=C:\local\boost_X_XX_X
set BOOST_LIBRARYDIR=C:\local\boost_X_XX_X\stage\lib
python setup.py install --yes USE_AVX_INSTRUCTIONS or python setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA
Now you can use import dlib without any problem in your python script.
You can also check the current version of dlib with pip show dlib.
Now simply install face_recognition with pip install face_recognition.
Enjoy!

Finally, I need to say thanks to @ageitgey and @davisking for their awesome work.

TheDogeOfTheInternet · 2017-09-14T13:25:03Z

You don't need to manually install dlib. I was able to install it with pip (through the pip install face_recognition command) after I had Boost and CMake installed.

Which leads me to my second point; your tutorial does not mention CMake at all. I have no idea what CMake actually does, so it may not be required, but if it does have something to do with simplifying the install process, you should add it to your tutorial.

masoudr · 2017-09-14T14:36:16Z

@TheDogeOfTheInternet yes you are right the CMake is a must and I forgot to add it but it is just used to compile dlib and Boost. I've edited my post and add it thanks.
And for your first question yes you can use pip to install it but the latest versions are always on his Github repository and website so you need to compile it by yourself. Also, you can configure your compilation.

ageitgey · 2017-09-17T00:39:27Z

Thanks @masoudr! I'll link it from the README.

ageitgey · 2017-09-17T00:49:59Z

Done! https://github.com/ageitgey/face_recognition/blob/master/README.md#installation

Thanks again!

PBShortStop · 2017-09-19T08:32:31Z

hello @masoudr, i want to know CMake install procedure. Thanks.

masoudr · 2017-09-19T09:32:44Z

@PBShortStop Installation of CMake in windows is very simple just grab the installation file (*.msi) from this link and install it. Remember to check the "Add CMake to system path" during the installation. Then you can simply use cmake --version in command prompt.

BachDoXuan · 2017-09-28T13:23:30Z

Dear all,
I've tried several times to build dlib, but waited more than 1 hour at face_recognition.cpp without seeing any progress. I redo it several times but still get stuck there. Can you help me with it?

runt1m33rr0r · 2017-09-28T14:26:10Z

@BachDoXuan you need to use the visual studio 2015 compiler(msvc-14.0), 14.1 is bugged. You also need at least 2GB RAM, because face_recognition.cpp takes a lot of memory during compilation(which could be the reason it takes so long).

BachDoXuan · 2017-09-28T21:43:58Z

I use VS CE 2017, 8GB RAM laptop. I use Windows 10 Pro but the windows is not activated. I have no idea what problem I have. Can you help me to install dlib?

masoudr · 2017-09-29T06:56:53Z

@BachDoXuan I used MSVC-14 and haven't tested the 2017 version. Are you using the precompiled version of Boost or compiling it by yourself?
Remember that some of the steps in this tutorial are for MSVC-14 and if you want to use with other versions you need to modify them.
Could you provide the error log?

BachDoXuan · 2017-09-29T08:25:43Z

@masoudr @neutrinobomber Thank you very much for your helps. The screen doesn't have any error log. It just got stuck when building dlib at face_recognition.cpp, I waited for more than hour every time I got there. But currently when I use command "pip install face_recognition" directly, then it succeeds.

masoudr · 2017-09-29T08:29:57Z

@BachDoXuan You are right, you can always use pip to install this package without any further work on windows. This tutorial is for the people who wanted to build dlib from source or do some configurations to it.

davisking · 2017-09-29T10:59:09Z

This is a known problem. Visual Studio 2017 is buggy and has worse support for C++11 than Visual Studio 2015. No one has been able to find a workaround other than to use Visual Studio 2015.

loqpa · 2017-10-04T15:32:42Z

Hey! I have a problem while following this tutorial.
My versions are:
Python 3.5.4
dlib 19.7
boost 1.65.1
(using "with cuda" and "with avx" options)

Any ideas how to fix it? I am up to trying everything you suggest:)

masoudr · 2017-10-04T16:15:12Z

@loqpa Hi,
Are you using a precompiled version of boost with MSVC14?
Try to add these system environment variables too:
VS110COMNTOOLS C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\
VS120COMNTOOLS C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\
VS110COMNTOOLS C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\
VSSDK140Install C:\Program Files (x86)\Microsoft Visual Studio 14.0\VSSDK\
I don't know the exact cause of your problem but it seems that some of the library files are not recognized by dlib.

loqpa · 2017-10-06T09:16:46Z

@masoudr Hello!
I am compiling boost by myself (following steps 3-1... 3-4) and my system environment variables were already set the way you suggested.
Tried with boost 1.63, got the same error.
Any other ideas?
By the way, i am using Anaconda python, in case it matters.

masoudr · 2017-10-06T15:45:35Z

@loqpa I used this method for the specified version of dependencies, so I am not sure if they work for other versions too.
As I know your problem is causing by missing some dll files on dlib's compile. I think you can try first submit your issue on dlib repository here, maybe @davisking have an answer to it and second use the exact procedure I mentioned here. I don't' know much about Anaconda try to exclude it.

Klinsman21 · 2017-10-07T19:11:42Z

Does anyone have the link to download, Microsoft Visual Studio 2015 with C / C ++ Compiler

masoudr · 2017-10-07T19:19:39Z

@Klinsman21 google is your friend :) try this.

loqpa · 2017-10-07T22:05:18Z

@masoudr what dlib version did you use? I can use precompiled version 19.4 without any problems but i am really curious about new(19.5+) cnn face_detector :)

masoudr · 2017-10-08T04:03:06Z

@loqpa If you compile dlib from the source you can always use the latest features and besides of that you can customize the compilation for specific configuration like disable/enable AVX instruction, CUDA feature, etc. I used v19.6 but newer versions would work too. You can find new features on dlib's website in here.

cmlyldz · 2017-10-11T15:39:05Z

Can anybody help me ?

masoudr · 2017-10-11T18:29:36Z

@cmlyldz You are trying to compile an X86 code on X64 compiler or vice-versa. Try to use VS2015 x86 Native Tools Command Prompt to compile dlib and remember that your python architecture must be same.

cmlyldz · 2017-10-12T08:27:48Z

@masoudr Thanks for answer. The problem was my python but there is no problem thanks to you.

hepingtao · 2017-10-13T10:06:21Z

@masoudr I have also encountered exactly the same problem as @cmlyldz . And I used VS2015 x86 Native Tools Command Prompt to compile dlib, but the problem didn't go.

masoudr · 2017-10-13T10:29:43Z

@hepingtao Please give me more information about the exact version of your tools like python version?

cmlyldz · 2017-10-13T13:04:48Z

@hepingtao be careful while downloading scipy, numpy you have to download them x86 like others(if you want to use x86). Also python, boost and also dlib must compile on x86 also. If you did everything in an x86 compiler (or x64) there will be no error.

008karan · 2017-10-15T15:30:20Z

I have installed cmak and added to path but while installing dlib getting message to install cmak

masoudr · 2017-10-15T19:22:39Z

@008karan If your CMake is successfully added, you can use cmake --version in cmd to verify that. I'm not sure if the problem will exist but put your complete error log here.

masoudr · 2020-04-08T06:09:45Z

@Ronneey This topic is about how to install face_recognition in Python so you need to follow the above steps to install it.
The datetime is a built-in Python module so no need to install it.
Use pip install opencv-python openpyxl to install opencv and openpyxl.
Hope this helps.

pandeng-001 · 2020-04-10T01:58:23Z

I install cmake, numpy,spicy,dlib,face_recognition sucessfully,but if I use 'import face_recognition',then python will return traceback ,such as
'Traceback (most recent call last):

How I can do? @masoudr

masoudr · 2020-04-10T07:20:42Z

@pandeng-001 It seems an installation issue because the models haven't installed properly. Try to reinstall face_recognition with pip install --upgrade --force-reinstall face_recognition and if it didn't help grab models from here and put them in D:\爬虫\lib\site-packages\face_recognition_models\models.

pandeng-001 · 2020-04-10T08:13:58Z

Ok, my issue is resolved with your help,thank you so much @masoudr

Snowball55 · 2020-04-12T00:56:47Z

should i have to use Microsoft Visual Studio 2015? I'm used to Pyhchram. Add i had installed boost and cmake but i still can't install dlib.

masoudr · 2020-04-12T06:34:53Z

@Snowball55 You would better go with the easy installation, but if you want to compile the source you will need MSVC but the version doesn't matter.
Anyway, it seems that your problem is using the wrong architecture, make sure that use the X64 version of the visual studio command prompt.

progmars · 2020-05-07T14:44:14Z

I wanted to have totally independent installation in a separate folder, so that's what I did:

Went to https://www.python.org/downloads/windows/ and chose "Python 3.6.8 - Dec. 24, 2018" -> "Windows x86-64 embeddable zip file" and extracted its contents to my newly prepared python3 folder.

Why 3.6.8 and not the latest one? Because I found prebuilt dlib binaries for 3.6 and none for 3.8. So, I hoped to get it working without having to install CMake. Otherwise, without CMake dlib installation failed, of course.

After that, I downloaded get-pip and put it too into python3 folder:
https://bootstrap.pypa.io/get-pip.py

Embedded Python has an issue - it ignores PYTHONPATH variable. To fix this, it turned out I have to add paths to pth file or delete the file. I chose to delete it (in my custom script below).

Here's the full cmd script that "worked on my machine". You can save it (install-standalone-deps.cmd) and put near your prepared python3 folder where you extracted Python 3.6.8 and get-pip.py, and then execute it.

@echo off
setlocal EnableExtensions DisableDelayedExpansion

cd %cd%\python3
set PYTHONPATH=%cd%
set PATH=%PATH%;%PYTHONPATH%;%PYTHONPATH%\Scripts;%PYTHONPATH%\Lib\site-packages
echo Standalone Python installation configured in %PYTHONPATH%

rem disabling embedded env file that causes PYTHONPATH to be ignored
if exist python36._pth ren python36._pth python36._pth.save

rem pip itself
python get-pip.py

rem Some important dependencies
pip install opencv-python

rem Installing prebuilt dlib that won't ask for CMake                                                 
pip install https://files.pythonhosted.org/packages/0e/ce/f8a3cff33ac03a8219768f0694c5d703c8e037e6aba2e865f9bae22ed63c/dlib-19.8.1-cp36-cp36m-win_amd64.whl
rem Installing face_recognition                  
pip install face_recognition

echo If there are no red error messages, then everything is OK and you can start running face recognition projects now.

pause

endlocal

Then I created another script that prepares environment. Let's call it setenv-py.cmd

@echo off
setlocal EnableExtensions DisableDelayedExpansion

set PYTHONPATH=%cd%\python3
set PATH=%PATH%;%PYTHONPATH%;%PYTHONPATH%\Scripts;%PYTHONPATH%\Lib\site-packages
echo Standalone Python installation configured in %PYTHONPATH%

rem Keeping it open for running Python commands
cmd /k

Then I prepared folder_with_pictures with some face images and ran setenv-py.cmd and entered command:

face_detection  folder_with_pictures

It worked! I received face coordinates.

So, I guess, nothing needed CMake? Or maybe it was picked up by some other place on my machine (but then why dlib installation failed unless I downloaded prebuilt binary?)

masoudr · 2020-05-07T15:37:16Z

@progmars In your script, you are installing dlib from a wheel package so there is no compilation. The CMake needs for compiling dlib from the source.

progmars · 2020-05-07T20:39:05Z

@masoudr Yeah, I guessed so. I just was afraid that some other dependency of face_recognition or deeper down the line would still require CMake and my idea would fail, but fortunately enough, it worked.

christopherpross · 2020-05-18T00:46:16Z

Hey,
my name is christopher proß. thank you for this grate project and for this tutorial. My question is the following:
I am writing at the moment an add-on for a screen-reader called nvda, a program which reads out screen elements too the blind on windows system. This program has the ability to be extended with add-ons in python. Which are executed at runtime. I would use this project for an add-on, but my problem is, to delever this requeriments to the end-users. exists there a way to precompile or prepack this all requeriments or pack it all to geter in an installer? Maybe someone can help me here.
All the best.

masoudr · 2020-05-18T05:54:04Z

@christopherpross You better create a new issue for your problem as this issue is related to installation on Windows.
If you want to deliver this to your end-user one way is to compile it as a stand-alone executable that accepts your desire parameters. You can follow this issue for compiling the script. Next, you can grab the executable and use it in your app without worrying about its requirements.

@masoudr thank you for your quick answer. an executable file is not my first choice, because I write a python script and this is only an add-on for an application. So importing it or call it like a dll seems to be better. call it as executable file over subprocess seems to me inperformant and not clean. Anyway. I had opened a new ussue. #1147

@masoudr I don't know if someones already asked, but this does not work with any other ides? I've been trying to install it and I use vscode so I don't know if that is an issue?

masoudr · 2020-05-26T05:44:09Z

@AkulPat The IDE doesn't relate to the installation of any Python packages unless you use a wrong environment within the IDE.
Remember that for this installation you need Visual Studio Command Prompt so if you want to install it inside your IDE, make sure that you select it instead of Windows CMD.
If you still have a problem post your error log for clarification.

progmars · 2020-05-26T06:46:37Z

@AkulPat or you can use a pre-built whl for Windows, as I did (see my post above) and then you won't need any build tools at all.
Caveat - those prebuilt wheels I found are available for older Pythons only and they seem to be without CUDA support, so it won't use GPU. For some tasks it's ok, it worked just fine for me for face feature extraction in real-time.

Hi, here is something that works for me:

1.- conda create -n face_recognition python==3.6.6 anaconda

2.- conda activate face_recognition

3.- pip install cmake

4.- pip install dlib==19.8.1

5.- pip install face_recognition

6.- pip install opencv-contrib-python==4.1.0.25

7.- pip install twisted

@raburgos thanks for the 7 steps.

I have tried step 1 on windows 10 pro with anaconda3x64 but i get the following at the end of packages, not sure if this is a required part as I am attempting to continue with the next steps;

ERROR conda.core.link:_execute(507): An error occurred while installing package 'conda-forge::alabaster-0.7.12-py_0'.
FileNotFoundError(2, 'The system cannot find the file specified', None, 2, None)

Hi!

It seems to be something with anaconda ... maybe you could try in command line: conda update ipykernel and then conda update --all

First step creates virtual environment in order to isolate the project (with Python versión 3.6)

akeilox · 2020-05-30T04:42:58Z

thanks for the direction.

guess im missing something here?

(base) C:\Users\acm>conda update ipykernel and then conda update --all
Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

and
then
update

Command line: conda update --all

oh wee thats embarrassing, yet to fully wake up.. update in progress, will try the steps again after all updated

raburgos · 2020-05-30T06:05:31Z

don´t worry about that! let me know if it works for you!

akeilox · 2020-05-30T06:45:44Z

@raburgos this works beautifully! thanks a million!
was on conda 4.8.3, open Anaconda Prompt

conda update ipykernel
conda update --all

repeat the above update till no error (took few runs for me), then run:

conda create -n face_recognition python==3.6.6 anaconda
conda activate face_recognition
pip install cmake
pip install dlib==19.8.1
pip install face_recognition
pip install opencv-contrib-python==4.1.0.25
pip install twisted

then clone the repo with git clone https://github.com/ageitgey/face_recognition.git
cd examples
face_detection ./

(that should output detected faces of pictures in that folder.

Thank you for your instruction! I have installed it successfully.
Does anyone know how to execute the facial recognition's command line on window 10?

Thank you.

Hi @Yipeng-Wang-Peter !

If you want to use your webcam you can try in command line (e.g: anaconda prompt, considering current path in your local file face_recognition):
.- cd examples
.- python facerec_from_webcam_faster.py

I hope this helps!

... and it stops at the most interesting part where the root cause of the error is located.

Python 3.8 - not sure if everything will work smoothly with the latest & greatest version. Why not try something that works, following the instructions given in the older comments here?
