dlib installation on Windows 10

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

1. Download the CMake installer and install it: https://cmake.org/download/

2. 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.

3. Restart The Cmd or PowerShell window for changes to take effect.

4. Download the Dlib source(.tar.gz) from the Python Package Index : https://pypi.org/project/dlib/#files extract it and enter into the folder.

5. 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

NOTE: Make sure to open the PowerShell as admin, and you're inside the dlib directory before proceeding to step 6

6. 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

Effective till now(2020).

pip install cmake
conda install -c conda-forge dlib

If you are using Anaconda Prompt (recommended),

conda install -c conda-forge dlib

Or you can use the approach mentioned below:

After spending a lot of time, this comment gave me the right result. https://github.com/ageitgey/face_recognition/issues/802#issuecomment-544232494

1. Download Python 3.6.8 and install, make sure you add it to PATH.

2. Install NumPy, scipy, matplotlib and pandas in your pc/laptop with this command in command prompt:-

   pip install numpy

   pip install scipy

   pip install matplotlib

   pip install pandas

3. Go to https://pypi.org/project/wheel/#files and right-click on filename wheel-0.33.6-py2.py3-none-any.whl (21.6 kB) and copy link address. Then go to your pc/laptop, open command prompt and write this command "python -m pip install" after this command space first then paste the link copied. After installing successful go to the next step.

4. Then go to this link, https://pypi.org/simple/dlib/ and right-click on filename "dlib-19.8.1-cp36-cp36m-win_amd64.whl" then copy link address. Then open command prompt and do the same as step 2 which is, write this command "python -m pip install" after this command space first then paste the link copied. then the dlib will be installed successfully.

5. After that, type python and enter, then type import dlib to check dlib is installed perfectly. you can proceed to install face recognition.py which suite for python 3.6.
