ModuleNotFoundError：没有名为“face_recognition”的模块

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)

当我运行上面的代码时，我发现以下错误消息。

回溯（最近一次调用最后一次）：文件“sample.py”，第 1 行，导入face_recognition

我检查过在安装库时是否发现了以下错误消息face_recognition。

pip install face_recognition

我的 python 版本是Python 3.7.1pip 是pip 19.0.3 from /Library/Python/2.7/site-packages/pip (python 2.7)

Answer 1

安装 Cmake：

sudo apt install cmake

对于 python3 不要pip单独使用，用于pip3安装未来的 python3 模块：

pip3 install face_recognition
