ModuleNotFoundError: No module named 'face_recognition'

Question

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

Is Cmake installed? Also I am assuming Ubuntu? – Jelle

Install Cmake then do pip3 install face_recognition – Cherenkov

Answer 1

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

Cherenkov

still not working even I've installed cmake and pip3 install face_recognition – Yore

got it, there is credential required to install pip3 install face_recognition. – Yore

facing similar kind of problem, Please can you share complete steps – Tapley

Answer 2

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).

Answer 3

For everyone who still found error when installing this step, I will give a brief requirements for your system.

1. Python3.9 [the most important]
2. Download dlib (this)

Next, after the above requirement fulfilled, do this.

1. pip install cmake
2. pip install dlib-19.23.0-cp39-cp39-win_amd64.whl
3. pip install opencv-python
4. pip install face_recognition

Bonus, in my case, I got error with the pillow library so you need to reinstall it, using these steps.

1. pip uninstall pillow
2. pip install Pillow

Well, I hope this will help, thanks.

Answer 4

This worked for me...

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

Answer 5

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
