import face_recognition
image = face_recognition.load_image_file("My_Image.png")
face_locations = face_recognition.face_locations(image)
print("I found {} face(s) in this photograph.".format(len(face_locations)
When I run above code, I've found following error message.
Traceback (most recent call last): File "sample.py", line 1, in import face_recognition
And I've checked that I've found following error message when I've installed face_recognition
library.
pip install face_recognition

and pip is pip 19.0.3 from /Library/Python/2.7/site-packages/pip (python 2.7)

First, you need to have CMake installed on your system.
brew install cmake
cmake --version
# cmake version 3.30.3
# this because it will takes some time
pip install face-recognition --verbose

pip install CMake==3.22.2
pip install dlib==19.18.0
pip install face_recognition

For everyone who still found error when installing this step, I will give a brief requirements for your system.
Next, after the above requirement fulfilled, do this.
Bonus, in my case, I got error with the pillow library so you need to reinstall it, using these steps.
Well, I hope this will help, thanks.

I was facing same issue, but then it solved through following steps:
Step 1: Download Microsoft Visual Studio 2015 or newer (check if build tools are enough).
Step 2: Download cmake (pip install cmake)
Step 3: Install dlib (pip install dlib)
Step 4: Install face-recognition (pip install face-recognition)
But install it in specific environment that will be used later for face_recognition code (In conda: activate environment name).

Install Cmake with:
sudo apt install cmake
And for python3 don't use pip
alone, use pip3
to install future python3 modules:
pip3 install face_recognition
