您好我正在尝试运行github存储库：

https://github.com/oarriaga/face_classification

如下：

MacBook-Pro:~/Downloads/face_classification-master$ pip install -r REQUIREMENTS.txt 
Collecting keras==2.0.3 (from -r REQUIREMENTS.txt (line 1))
  Using cached Keras-2.0.3.tar.gz

No matching distribution found for opencv2-python==3.2.0 (from -r REQUIREMENTS.txt (line 9))

然而我在使用opencv时遇到错误，然后我尝试了：

MacBook-Pro:~/Downloads/face_classification-master$ pip3 install -r REQUIREMENTS.txt 
Collecting keras==2.0.3 (from -r REQUIREMENTS.txt (line 1))
  Using cached Keras-2.0.3.tar.gz

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local,
because opencv3 and opencv install many of the same files.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/opencv3/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/opencv3/lib
    CPPFLAGS: -I/usr/local/opt/opencv3/include
For pkg-config to find this software you may need to set:
    PKG_CONFIG_PATH: /usr/local/opt/opencv3/lib/pkgconfig


If you need Python to find bindings for this keg-only formula, run:
  echo /usr/local/opt/opencv3/lib/python2.7/site-packages >> /usr/local/lib/python2.7/site-packages/opencv3.pth
  mkdir -p /Users/adolfocamachogonzalez/Library/Python/2.7/lib/python/site-packages
  echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/adolfocamachogonzalez/Library/Python/2.7/lib/python/site-packages/homebrew.pth
==> Summary
  /usr/local/Cellar/opencv3/3.2.0: 498 files, 63.2MB, built in 6 minutes 58 seconds

之后当我尝试运行代码时出现错误：

MacBook-Pro:~/Downloads/face_classification-master/src$ python video_test.py 
Traceback (most recent call last):
  File "video_test.py", line 1, in <module>
    import cv2
ImportError: No module named cv2

所以我真的很感谢对此的支持。

答案 0 :(得分：1)

正如错误消息所述，您缺少opencv的python绑定。 使用自制软件安装时，您必须在命令中添加--with-python或/和--with-python3。

brew install opencv3 --with-ffmpeg --with-tbb --with-contrib --with-python
