How to install dlib library for Python in Windows 10

Hi! This is my first blog (or article depending on what you call) in English. Anyway, I am writing this blog because I have been facing with the trouble of this package for a while. I was trying to google it for the solution but I could not find the alternative one. So! this is my solution to install dlib library in Windows 10.

Some people might say that why don’t you just use conda install which is already complied. It is much easy to install. Well… I agree and I could do it. However, other packages, such as face_recognition could not leverage dlib when you used conda install . Hence, we need to use pip install .

Preparation

First thing first, there are two things required (really need it indeed!).

• CMake: This is because dlib was developed in C based programming language, so it needs this program to use it. It can be found in the link https://cmake.org/download/. To make sure matching with your operation system, in our case is Windows 10 64-bit version.

Sometimes we need manage the Windows PATH environment for CMake. (If you already added during installation, you can skip this section).

For checking whether the PATH already added or not, you can go to Environment Variables on Windows by go to This PC > Properties > Advance system settings. Then, go to Tab Advanced and click on Environment Variables.

Another windows will pop-up and click Edit…

If you are unable to find CMake path, you should add the CMake installed directory like image below.

Install

Everything is looking good so far. Now we can install dlib into our python environment. First of all, you need to install CMake library.

Then, you can install dlib library using pip install .

After passing enter, you laptop or desktop will run the C, C++ Compiler. If you got something like image below, you would be fine.

After these all, you will get dilb installed on your Windows 10 by not using conda install compiler.

For further discussion or anyone would like to contact me. We could do it over the LinkdIn below.

Я хочу использовать dlib с Python для распознавания изображений. У меня есть приложение питона работает большой с OpenCV на Windows 10, но когда я хочу установить dlib с cmd ней дает мне это следующее сообщение об ошибке:

ошибка: не удается найти cmake, убедитесь, что он установлен и находится в пути. Вы можете установить cmake, используя инструкции по адресу https://cmake.org/install/. Вы также можете указать его путь с параметром —cmake.

Что я должен делать?

Установите Dlib из .whl

Dlib 19.7.0

Вы можете проверить его, загрузив пример с сайта, например SVM_Binary_Classifier.py, и запустив его на своем компьютере.

Установите Dlib из источника

Dlib > 19.7.0

1. Загрузите исходный код (.tar.gz) из индекса пакетов Python: https://pypi.python.org/pypi/dlib
2. Запустите setup.py: sudo python setup.py install (Linux) или python setup.py install (Windows)

примечание: эта процедура предполагает, что у вас установлен CMake .

Следуй этим шагам:

• pip install cmake
• Установите инструменты сборки Visual Studio отсюда .
• В Visual Studio 2017 перейдите на вкладку «Отдельные компоненты», «Инструменты Visual C ++ для Cmake» и установите флажок в разделе «Компиляторы, инструменты сборки и среды выполнения».
• pip install dlib

Вам необходимо установить Cmake .

dlib — это библиотека c ++ с привязками к python. Это должно быть построено сначала. Я думаю, это произойдет автоматически после установки Cmake

1 плюс

Вы должны установить cmake, как об ошибке говорит вам.

или напрямую установите cmake отсюда https://cmake.org/download/

После установки cmake pip install dlib должен работать.

У меня были установлены инструменты для сборки vstudio, когда я делал свой тест.

Установите dlib в Windows

Извлеките cmake и настройте его как переменную среды для извлеченного пути, где он был C: \ Users \ admin \ Downloads \ cmake-3.8.1-win32-x86 \ cmake-3.8.1-win32-x86 \ bin

Теперь распакуйте zip-файл dlib и перейдите в папку dlib

Следуйте этой команде

Теперь перейдите в папку Release, которая будет находиться в каталоге dlib \ test \ build \ Release, и выполните эту команду dtest.exe —runall

Этот процесс занимает время, так как cmake компилирует все файлы C ++, поэтому будьте спокойны. Наслаждаться.

Выберите файл .lib dlib в соответствии с установленной версией Python. Например , если установлена версия 3.6.7 питон, система 64 — битной или если питон 3.5.0 32 бит затем выбрать dlib-19.5.1- cp36 -cp36m-win_ amd64 .whl и dlib-18.17.100- cp35 -отсутствует- win32 . соответственно

Текст, выделенный полужирным шрифтом, говорит о поддержке Python.

Скачайте файл колеса отсюда или скопируйте адрес ссылки

для вышеуказанного метода .whl файл должен находиться в рабочем каталоге

Ниже ссылка для python3.6 с поддержкой dlib link, для python 3.5 u можно заменить на dlib 35.whl link

тогда вы можете установить пакет face_recognition

Install OpenCV 3 and Dlib on Windows ( Python only )

November 30, 2017 By 59 Comments

This is an old blog and some information might be obsolete. We have published new instructions. You can find them here:

We already have a post for installing OpenCV 3 on Windows which covers how to install OpenCV3 from source for working with both C++ and Python codes. However, many readers have faced problems while installing OpenCV 3 on Windows from source. This post is for those readers who want to install OpenCV on Windows for writing Python code only.

If you are still not able to install OpenCV on your system, but want to get started with it, we suggest using our docker images with pre-installed OpenCV, Dlib, miniconda and jupyter notebooks along with other dependencies as described in this blog.

Step 1: Install Anaconda (a python distribution)

Download and install Anaconda 64-bit version from https://www.continuum.io/downloads.

It is advised to install Anaconda for Python 3.

While installing Anaconda make sure that you check both options:

1. Add Anaconda to my PATH environment variable
2. Register Anaconda as my default Python

Step 2 : Create Virtual Environment

Open the command prompt and execute the following command.

You should get an output as shown below:

Press Enter and the environment will be installed and you should get an output as shown below :

Step 3 : Install OpenCV

3.1. Activate the environment

3.2. Install OpenCV and other important packages

Continuing from the above prompt, execute the following commands

3.3. Test your installation

Open the python prompt on the command line by typing python on the command prompt

You should get the following output

How to install Dlib for Python 3 on Windows

In this video we will see how to install the Dlib library for Python 3 on Windows.

In this specific tutorial we are going to install Dlib 19.8 for Python 3.6 (64 bit version). We choosed this specific version as it’s the latest one (March 2019 the moment I’m writing this post) which has ready binaries for windows.
In other words is the one that is really easy to install.

In this website you find all the binaries available at the moment:
https://pypi.org/simple/dlib/

If you don’t have Python and Opencv installed yet, go first with Python and Opencv installation following this tutorial.

Install Dlib for Python 3.6:

1. Python 3.6 (64 bit) has to be already installed.
2. Run Windows Prompt Command. You can type on the search bar “CMD”.
   
   Remember to click with right button of the mouse and then “Run it as administrator”, otherwise you might not have the permission to install the library.
3. Type on the prompt command:
4. Once you see the message “Successfully installed dlib“, it means that the installation has been completed.

You can now run Python, try importing the dlib library. If you don’t get any error, it means that the installation was done correctly.

Install Dlib on Windows

June 12, 2017 By 45 Comments

In this post, we will provide step by step instructions on how to install Dlib on Windows.

Compiling Python modules such as NumPy, SciPy etc. is a tedious task. Anaconda is a great Python distribution which comes with a lot of pre-compiled Python packages. So we will use Anaconda as our Python distribution.

An alternative to Anaconda is that you install official Python library and use Christoph Gohlke’s awesome repository to install pre-compiled Python modules.

This tutorial is based on using Anaconda so we may not be able to help if you choose to use Gohlke’s precompiled binaries or if you compile Python libraries from source.

If you intend to use Dlib only in C++ projects, you can skip Python installation part.

Now let’s go through the steps to install Dlib. Follow our previous post Install OpenCV3 on Windows to complete Step 1, 2 and 3.

Step 1: Install Visual Studio 2015

Step 2: Install CMake v3.8.2

Step 3: Install Anaconda 3

Step 4: Download Dlib

Step 5: Build Dlib library

Extract this compressed file. Open Windows PowerShell or Command Prompt and move to the directory where you have extracted this file.

If you are running these commands on Command Prompt replace ` (backtick) with ^ (caret).

Dlib will be installed within dlib-19.6\build\install directory. We will use CMake to build Dlib examples but you can use Visual Studio too. This directory (dlib-19.6\build\install) contains include and library folders which you can specify in Visual Studio to build projects using Dlib.

Step 6: Update user environment variable – dlib_DIR

This environment variable is needed for CMake to find out where Dlib is installed. CMake looks for a file named dlibConfig.cmake within directory dlib_DIR to find Dlib’s include and library directories.

1. Press Windows Super key, search for “environment variables”.
   
2. Click Environment Variables in System Properties window.
   
3. Click New in “User Variables” (in upper half of window).
4. Under variable name write dlib_DIR and under variable value write full path to directory dlib-19.6\build\install\lib\cmake\dlib
   On my machine path is: D:\programming\dlib-19.6\build\install\lib\cmake\dlib
   This directory contains file “dlibConfig.cmake”. This is used by CMake to configure dlib_LIBS and dlib_INCLUDE_DIRS variables to generate project files. Before assigning the value to variable dlib_DIR make sure that this path has file dlibConfig.cmake.
5. Now click ok to save and close environment variables window.

Note: If you have an open Command Prompt/Power Shell window before these values were updated, you have to close and open a new Command Prompt/Power Shell window again.

Step 7: Build Dlib examples

We will use our CMakeLists.txt file instead of one which is shipped with Dlib.
Download modified CMakeLists.txt file and put it in dlib-19.6\examples directory and replace the default one with this one. Then follow the steps given below:

Once build is complete, it will generate executables for all examples in examples\build\Release folder.

Step 8: Test Dlib’s C++ example

We will test Face Landmark Detection demo to check whether we have installed Dlib correctly.
Download trained model of facial landmarks from Dlib’s website. Extract this file (shape_predictor_68_face_landmarks.dat.bz2) to Dlib’s root directory (dlib-19.6).

Step 9: Install Dlib’s Python module (Only Anaconda 3)

Compiling Python bindings for Dlib from source is non-trivial. You have to compile Boost.Python from scratch and configure some environment variables (such as BOOST_ROOT and BOOST_LIBRARYDIR) before you can compile Python module of Dlib. We are skipping that part for now. A complete tutorial on how to build Dlib Python bindings from source will be released in future.

To save time and efforts it is suggested to use Anaconda 3. You can install a compiled binary of dlib v19.4 from Anaconda. At the time this article was updated Dlib’s latest available version on Anaconda’s conda-forge repository is 19.4. So we will install v19.4 instead of 19.6

Step 10: Test Dlib’s Python example
