Have you try this steps? Face-recognition on windows
Officially this package is not supporting windows but this steps might be help you.
Also the another way is you can download it's environment with virtual box on windows system. From here pre-configured VM
I guess it will help you. Thank you

Why don't you adopt deepface? It is more lightweight and it covers Keras based facial recognition models. In other words, it is easier to install and run.
#!pip install deepface
from deepface import DeepFace
models = ["VGG-Face", "Facenet", "OpenFace", "DeepFace", "DeepID"]
res = DeepFace.verify("img1.jpg", "img2.jpg", model_name = models[0])

Pip doesn't work, says it cannot build wheels

I've looked online for a solution but haven't found one.
I have a new computer which is the first desktop I own and I need to install python and pip and all these things for a high school project, but when installing PyTorch and other packages I need I am met with this error:

Note that your error is caused by c:\program files\inkscape\bin\python.exe, which is almost certainly entirely the wrong python executable, because that's not where python installs itself.
Uninstall whatever you installed, then grab the latest installer from https://www.python.org/downloads/windows/, run that (with admin rights, because hopefully you remembered to make sure your own account is set to a normal account type and NOT an admin account, for obvious security reasons), then when that's finished installing, make sure to update your PATH:
run "advanced system settings"
click the "environment variables" button
double click the PATH entry in "system variables" section
verify that both C:\Program Files\Python38\ and C:\Program Files\Python38\Scripts\ are in there. If not, add them. (or whatever the location is you custom-installed them to of course).
possibly necessary: also check to see if there is an Inkscape entry in your Path. If there is, use the "move up"/"move down" buttons to make sure that the Python entries are listed above the Inkscape entry.
Then you can start cmd/powershell/etc with admin rights (if you already had one open, close it and start a new one for the updated PATH to be in effect) and just use pip (not pip3) to install packages globally.
That said, for projects you almost always want to use python's "virtualenv" concept, explained over on https://docs.python.org/3/tutorial/venv.html, which lets you install dependencies locally, which means that if one project requires, say, Django 2.10 and another requires Djangoo 3.0, each of them installs in their own virtual environment, instead of causing a global dependency conflict.

In the end, I ended up using anaconda and it worked. Thanks a lot, but setting these things up drives me nuts and I may not have the skill to understand a lot of the instructions...

I am using Python 3.7.3 and I have cpython installed. I have checked everywhere and no solution is working for me. I have tried downgrading python, thinking it might work for older version using the following but it does not even downgrade it to the given version.
conda install python=3.5.0
How do I solve this?

For me installation failed with error: command 'gcc' failed with exit status 1.
This worked for me:
pip install cython
pip install git+https://github.com/lucasb-eyer/pydensecrf.git
Installing cython is the first thing you need to try out.That alone didn't work for me.Combination of both worked like a charm.
Referred to the comments at https://github.com/lucasb-eyer/pydensecrf/issues/78

Step1: download package of pydensecrf compatible with python version from link https://anaconda.org/conda-forge/pydensecrf/files?version=1.0rc2&page=2
Step2: Extract the package and copy two subfolders "pydensecrf and pydensecrf-1.0rc2.dist-info" in folder "Lib" to installed folder of python (Example: C:\Python 3.6\Lib\site-packages)

Lief won't install | couldn't build wheel for lief

I got lief working just fine on my Desktop (windows), but it refuses to install on my MacBook. I'm newer to Python development and installing new libraries, so maybe there's something I'm missing. I have Python 3.6 and 3.7 on my machine (is that a possible issue?). Lief appears to have support for Python 3.6, but I can't seem to install it using "pip install lief" or "pip3 install lief". I've updated setuptools but that doesn't seem to make any difference, either.

Most notably; it fails to build the wheel. I've installed wheel many times thinking the install might've been broken, but I don't think that's the case anymore. Anyone have any ideas?

As with everything I ever post to this site, I found a solution to the problem the moment I posted. I downloaded the egg file from github.com/lief-project/LIEF/releases and pasted it in the /Users/NAME directory... all good. Gonna leave this up for anyone else having similar issues...

Hello for this problem make this
step 1:
pip install cmake dlib
step 2:
pip install face-recognition
If you have the problem by dlib check this
sudo apt install python3-dev
