ModuleNotFoundError:没有名为"face_recognition"的模块 [英] ModuleNotFoundError: No module named 'face_recognition'

问题描述

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)

运行上述代码时，发现以下错误消息.

When I run above code, I've found following error message.

回溯(最近一次通话最后一次):文件"sample.py"，位于第1行导入face_recognition

Traceback (most recent call last): File "sample.py", line 1, in import face_recognition

并且我检查了安装 face_recognition 库时是否发现以下错误消息.

And I've checked that I've found following error message when I've installed face_recognition library.

pip install face_recognition

我的python版本是 Python 3.7.1 ，pip是/library/Python/2.7/site-packages/pip(python 2.7)中的 pip 19.0.3

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)

推荐答案

使用以下命令安装Cmake:

Install Cmake with:

sudo apt install cmake

对于python3，不要单独使用 pip ，请使用 pip3 安装将来的python3模块:

And for python3 don't use pip alone, use pip3 to install future python3 modules:

pip3安装face_recognition
