dlib installation on Windows 10

问题

I want to use dlib with python for image recognition. I have the python app running great with OpenCV on Windows 10, but when I want to install dlib from the cmd it gives me this following error :

error: Cannot find cmake, ensure it is installed and in the path. You
can install cmake using the instructions at https://cmake.org/install/
You can also specify its path with --cmake parameter.

What should I do?

Install Dlib from .whl

Dlib 19.7.0

pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f

You can test it, downloading an example from the site, for example SVM_Binary_Classifier.py and running it on your machine.

Note: if this message occurs you have to build dlib from source:

dlib-19.7.0-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform

Install Dlib from source (If the solution above doesn't work)

Windows Dlib > 19.7.0

Download the CMake installer and install it: https://cmake.org/download/
Add CMake executable path to the Enviroment Variables:

set PATH="%PATH%;C:\Program Files\CMake\bin"

note: The path of the executable could be different from C:\Program Files\CMake\bin, just set the PATH accordingly.

note: The path will be set temporarily, to make the change permanent you have to set it in the “Advanced system settings” → “Environment Variables” tab.
Restart The Cmd or PowerShell window for changes to take effect.
Download the Dlib source(.tar.gz) from the Python Package Index : https://pypi.org/project/dlib/#files extract it and enter into the folder.
Check the Python version: python -V. This is my output: Python 3.7.2 so I'm installing it for Python3.x and not for Python2.x

note: You can install it for both Python 2 and Python 3, if you have set different variables for different binaries i.e: python2 -V, python3 -V
Run the installation: python setup.py install

Linux Dlib 19.17.0

sudo apt-get install cmake

wget https://files.pythonhosted.org/packages/05/57/e8a8caa3c89a27f80bc78da39c423e2553f482a3705adc619176a3a24b36/dlib-19.17.0.tar.gz

tar -xvzf dlib-19.17.0.tar.gz

cd dlib-19.17.0/

sudo python3 setup.py install

note: To install Dlib for Python 2.x use python instead of python3 you can check your python version via python -V

Follow these steps:

pip install cmake
Install Visual Studio build tools from here.
In Visual Studio 2017 go to the Individual Components tab, Visual C++ Tools for Cmake, and check the checkbox under the "Compilers, build tools and runtimes" section.
pip install dlib

回答3:

You need to install Cmake.

dlib is an c++ libary with python bindings. It needs to be builded first. My guess is this will happen automatically once you have installed Cmake

回答4:

You have to install cmake as the error tells you.

you can follow this instructions https://www.learnopencv.com/install-dlib-on-windows/

or directly install cmake from here https://cmake.org/download/

Once cmake is installed pip install dlib should work.

I had vstudio building tools installed whe I did my test.

回答5:

Choose dlib .whl file according to your installed python version. For example if installed python version is 3.6.7 , 64bit system or if python is 3.5.0 32 bit then choose dlib-19.5.1-cp36-cp36m-win_amd64.whl and dlib-18.17.100-cp35-none-win32.whl respectively.

Bolded text says the python supporting version.

Download wheel file from here or copy the link address

pip install dlib-19.5.1-cp36-cp36m-win_amd64.whl

for above method .whl file shoud be in the working directory

Below link for python3.6 supporting dlib link, for python 3.5 u can replace with dlib 35.whl link

pip install https://files.pythonhosted.org/packages/24/ea/81e4fc5b978277899b1c1a63ff358f1f645f9369e59d9b5d9cc1d57c007c/dlib-19.5.1-cp36-cp36m-win_amd64.whl#sha256=7739535b76eb40cbcf49ba98d894894d06ee0b6e8f18a25fef2ab302fd5401c7

Just a quick update on what has worked for me (two years later). Davis King has provided two ways to add the latest python dlib (19.17.0) to any python environment in Windows 10 for me. Note, I run several Linux configs in Oracle VirtualBox but Windows 10 is my native OS which has access to the Nvidia GPU so i need an install on Windows 10. (Cannot access the GPU - easily - through VirtualBox).

First - the easiest:

pip install dlib

and the website link: https://pypi.org/project/dlib/

And then it can be easily be build from sources. Download from https://pypi.org/simple/dlib/ and follow instructions on http://dlib.net/compile.html.

Also, just found another way to access with Visual Studio 2019 (or 2017). Use vcpkg - see link https://vcpkg.readthedocs.io/en/latest/

I built dlib 19.17 on Windows 10 with CMake and it worked fine but then I found vcpkg and now the dlib libraries are integral to the Visual Studio. I no longer need to add all the external links to C++ and the linker.The version in vcpkg is currently 19.16-1 and it is built with full CUDA support.

Hope this helps others..

回答7:

You can use vcpkg to install dlib.

If you don't have vcpkg, you can get it here (Read Quick Start)

After you got vcpkg, run:

vcpkg install dlib:x64-windows

Simple and 100% working trick

(Make sure you install cmake)

My Anaconda python ver : 3.6.8 (64 bit) | OS :Windows 10

python -m pip install https://files.pythonhosted.org/packages/0e/ce/f8a3cff33ac03a8219768f0694c5d703c8e037e6aba2e865f9bae22ed63c/dlib-19.8.1-cp36-cp36m-win_amd64.whl#sha256=794994fa2c54e7776659fddb148363a5556468a6d5d46be8dad311722d54bfcf

I have recently installed dlib on python 3.7. First I have installed cmake from anaconda navigator (cmake version 3.14.0) Next i installed visual studio 2019 and installed Desktop development with C++ . Then I do pip install dlib and now its working

回答10:

Install dlib in Windows

download dlib from https://github.com/davisking/dlib.git

download camke from https://cmake.org/download/

Extract cmake and configure it as Environment variable to the extracted path my it was C:\Users\admin\Downloads\cmake-3.8.1-win32-x86\cmake-3.8.1-win32-x86\bin

Now extract dlib zip file and go to dlib folder

Follow this commands

cd dlib/test
mkdir build
cd build
cmake ..
cmake --build . --config Release

Now go to Release folder which would be at dlib\test\build\Release and execute this command dtest.exe --runall

This process takes time as cmake compiles all C++ files so stay clam. Enjoy!!!

I was also facing the Cmake errors like

Building for: NMake Makefiles
CMake Error in CMakeLists.txt:
  Generator

    NMake Makefiles

  does not support platform specification, but platform

    x64

  was specified.

While installing dlib You must first install Anaconda navigator as it will allow you to switch environments. Now follow these instructions:

https://youtu.be/Q4_M8YTAPDg Follow this link to understand how to create new environment and this video will also tell you how to install dlib in that environment.
Now you have new environment with dlib installed open anaconda navigator and go to environment tab on left side of the anaconda navigator window, here you will see the environment you just created if not you can import that environment from the location where you created it. Click on that environment to load.
Now Go to home Tab,then install and launch spyder for this new environment.

You are now ready to write code in this spyder with dlib working.

NOTE: I had my visual studio installed while doing this but I think this will also work if you do not have Visual Studio installed on your system. Hope It will work for you all :)
