python - 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)

当我运行上面的代码时，我发现了以下错误消息。

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

我检查了我在安装时是否发现了以下错误消息 face_recognition图书馆。
pip install face_recognition

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

Answer 1

使用以下命令安装 Cmake:
sudo apt install cmake
而对于 python3 不要使用 pip单独使用 pip3安装 future 的python3模块:
pip3 install face_recognition
