ubuntu16.04如何安装dlib

Step 1: Install OS libraries

/sudo apt-get install build-essential cmake pkg-configsudo apt-get install libatlas-base-dev libboost-python-dev/

Step 2: Compile C++ binary

/cd dlib-19.6/

cd dlibmkdir buildcd buildcmake ..cmake --build . --config Releasesudo make installsudo ldconfigcd ../

上述是本人编译的步骤。

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

Step 1: Install OS libraries

/sudo apt-get install build-essential cmake pkg-configsudo apt-get install libx11-dev libatlas-base-devsudo apt-get install libgtk-3-dev libboost-python-dev/

Step 2: Install Python libraries

/sudo apt-get install python-dev python-pip python3-dev python3-pipsudo -H pip2 install -U pip numpysudo -H pip3 install -U pip numpy/

We will use Virtual Environment to install Python libraries. It is generally a good practice in order to separate your project environment and global environment.

Step 3: Compile DLib

Step 3.1: Compile C++ binary

Davis King, creator of Dlib, recommends using CMake for using Dlib in your code.
But if you want to use Dlib as a library follow these steps:

/wget http://dlib.net/files/dlib-19.6.tar.bz2tarxvf dlib-19.6.tar.bz2cd dlib-19.6/mkdir buildcd buildcmake ..cmake --build . --config Releasesudo make installsudo ldconfigcd../

Now you can use pkg-config to provide path to Dlib’s include directory and link Dlib library file.

/pkg-config --libs --cflags dlib-1/

Step 3.2: Compile Python module

Activate Python virtual environment.

/############ For Python 2 ############workon facecourse-py2 ############ For Python 3 ############workon facecourse-py3/

Now let’s compile and install Dlib’s Python module.

/# move to dlib's root directorycd dlib-19.6python setup.py install# clean up(this step is required if you want to build dlib for both Python2 and Python3)rm -rf distrm -rf tool/python/buildrm python_examples/dlib.so/

We have cleaned up few files and directories because Dlib creates Python modules for Python2 and Python3 with the same name. Suppose you ran the setup.py in Python2 virtual environment, it will generate dlib.so in python_examples directory. Now if you deactivate Python2 virtual env, activate Python3 virtual env and run setup.py file, it will replace dlib.so (which was compiled with Python2) in python_examples directory with newer one (which is compiled with Python3). When you will try to run any python_example from within this directory, it will import this dlib.so instead of one located in site-packages or dist-packages directory and throw an error. Although this error won’t occur is a local copy of dlib.so is not present in current directory but it is better to remove local copies to avoid any confusion.

For consistency, we have installed Python and C++ binaries of Dlib using the same source code.

If you are going to use only Python module of Dlib you can also install Python bindings for Dlib using pip.

/pip install dlib/

Now you can exit from Python virtual environment.

/deactivate/

Now, whenever you are going to run Python scripts which use Dlib you have to activate the virtual environment using workon command.

• Stephen Meschke

  Great tutorial! Thanks: https://youtu.be/jKkoFTgjn2k

  Hello Satya Mallick. Your tutorials are really great and they have helped me to improve my skills in CV and ML. I followed the instructions of this post and installed the dlib library in my ubuntu OS. I had installed the opencv for python and c++ and the dlib for python before.
  know I have the library in this path:

  behnam@ubuntu:/usr/local/include$ ls
  dlib opencv opencv2 python3.6m

  pkg-config –libs –cflags dlib-1
  -I/usr/local/include -I/usr/include/libpng12 -L/usr/local/lib -ldlib -lpng12

  I want to use the library for the landmark detection in Qt project. I need both opencv and dlib. But after running the code Qt complains about Error 2 and the qmake could not find the correct path. I could not solve the problem.
  I run this code by adding the existing source and adding the dlib include path and in the release mode the speed is acceptable. The opencv installed library is fine but I can not use the dlib installed library. Here is my .pro file. Any help would be really really appreciated.

  QT += core
  QT -= gui

  TARGET = dlibTest
  CONFIG += console
  CONFIG -= app_bundle

  TEMPLATE = app

  SOURCES += main.cpp

  INCLUDEPATH += /usr/local/include/opencv -I/usr/local/include -L/usr/local/lib

  LIBS += `pkg-config opencv –libs` `pkg-config –cflags dlib-1`

  QMAKE_CXXFLAGS += -std=c++11

  • Vaibhaw Singh Chandel

    I would have a better idea if you can post error message too.
    btw shouldn’t LIBS be
    LIBS += `pkg-config --libs opencv` `pkg-config --libs dlib-1`

    • Behnam Zeinali

      Hello and thanks for replying.
      You right. I changed it and this is my .pro file:

      QT += core
      QT -= gui

      TARGET = dlibTest
      CONFIG += console
      CONFIG -= app_bundle

      TEMPLATE = app

      SOURCES += main.cpp

      INCLUDEPATH += /usr/local/include/opencv -I/usr/local/include
      INCLUDEPATH += /usr/local/include

      LIBS += `pkg-config opencv –libs`
      LIBS += -I/usr/local/include
      LIBS += -I/usr/include/libpng12
      LIBS += -L/usr/local/lib -ldlib -lpng12

      QMAKE_CXXFLAGS += -std=c++11

      But now I have three errors <img class="emoji" alt="
