ModuleNotFoundError: No module named 'face_recognition'

问题

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

My python version is Python 3.7.1 and pip is pip 19.0.3 from /Library/Python/2.7/site-packages/pip (python 2.7)

回答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

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).
