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?

My command prompt error

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

  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
