ModuleNotFoundError: No module named 'face_recognition'

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 以上代码时,我发现了以下错误消息。

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

而且我已经检查过我在安装 face_recognition 库时发现了以下错误消息。

pip install face_recognition

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

安装 Cmake:

sudo apt install cmake

并且 python3 不要单独使用 pip,使用 pip3 安装未来的 python3 模块:

pip3 install face_recognition

我遇到了同样的问题,但后来通过以下步骤解决了:

第 1 步:下载 Microsoft Visual Studio 2015 或更新版本(检查构建工具是否足够)。

第 2 步:下载 cmake(pip 安装 cmake)

第 3 步:安装 dlib(pip 安装 dlib)

第四步:安装人脸识别(pip install face-recognition)

但是安装在特定的环境中,稍后将用于face_recognition代码(在conda中:激活环境名称)。
