问题
I cant install dlib on python with cmd , I have downloaded cmake and putted it on PATH, or is there any plugin i have to download it first ? Or does my pip's environment is located at a wrong place ? Or do I have to change my python to 64 bit instead of 32 bit ? If I have to do so , please let me know the way to do it , I am a newbie
C:\Users\Yusuf>python -m pip install dlib --user

Please help me thank you !
回答1:
NOTE:First make sure you have installed c++ compilers and cmake Then start following the sptes:
go to dlib on github
click on clone or download button and then download the package manually by clicking on the zip download And after the download finished , extract the file and put it in desktop
3.Then open Powershell or cmd
4.type in the command cd C:/users/(your username)/Desktop/master-dlib/master-dlib
5.Then when you changed your current working directory then type in the command python setup.py install
NOTE2: This is the manual way but also look into This Too.
