Installation of dlib with pip fails on Windows 10

Question

I tried a lot to install pip install dlib but it always shows an error and I reinstalled cmake.

I got the error:

pip install dlib

Do the following:

1.go to github repository of dlib package

2.click on the the green button which has written clone or download

3.Then click on Download Zip

4.after the download finished , extract the zip file and save it in desktop

NOTE: First intall CMake and then start following other steps.

5.go to dlib-master/dlib-master and copy the directory of dlib-master folder which for you should be C:\Users\(you'r username)\Desktop\dlib-master\dlib-master, if you followed the steps.

6.Then open pwershell and type cd C:\Users\(you'r username)\Desktop\dlib-master\dlib-master

NOTE: IF you have not installed CMake properly , consider installing it , so that you can install the dlib module without any problem.

7.When you changed your current working directory by typing the above command, Then type python setup.py install

8.If you have installed cmake, then the package would install easily and flawlessly.

after hit enter on 'site.getsitepackages()' i get this output instead of any environment directory. ['C:\\Program Files\\Python37', 'C:\\Program Files\\Python37\\lib\\site-packages'] – Shantanu Gupta Dec 14 '19 at 17:25
as I said @ShantanuGupta, choose the second one and follow along the steps – moh80s Dec 14 '19 at 17:40
@ShantanuGupta if it worked; accept the answer maybe; so that other people can benefit from your question. – moh80s Dec 14 '19 at 18:17
@ShantanuGupta, I updated the answer, This should work now. – moh80s Dec 15 '19 at 04:55

I executed setup.py as @Moh Vahedi said and got following error in cmd:

You must use Visual Studio to build a python extension on windows. If you are getting this error it means you have not installed Visual C++. Note that there are many flavors of Visual Studio, like Visual Studio for C# development. You need to install Visual Studio for C++.

So I'm installing VS now :)

Downgrade your python to 3.6 For Python 3.6 everything installs normally

or

If it still not work - use it on linux --- for that you have to enable Wsl in windows- (windows subsystem for linux ) in your laptop -- then install Ubuntu 20.XX and and install anaconda and use Dlib there

If You still want to install DLib

For installing DLib in windows 10 , make sure you have installed Anaconda version 2020.02 or above (Released in march 11 2020)

If you already installed anaconda which was installed before march 11 2020, i recommend to uninstall it completely, then install latest version of anaconda ,, and don't forget to check the path option ,

Then install cmake 'pip install cmake' ,

then install 'pip install face-recognition'

go to -- {https://pypi.org/project/auto-face-recognition/#files}

Now download the file with extension .whl --https://files.pythonhosted.org/packages/c9/9a/68e57a65018b758e274aed7f0c48808433bd792b73102b516d4f3abb3be5/auto_face_recognition-0.0.3-py3-none-any.whl

*** note over the period this link could change

download this whl file into your folder where your face recognition codes already there

or save it seperately in some library folder

Now Close all anaconda windows like, spyder, jupyter etc

navigate to folder containing whl file copy the path - Now go to anaconda prompt - and first go folder where whl file is stored - cd [path of folder] , then run

pip install [wheelfile name].whl
