Anaconda找不到模块cv2

Question

I am using Anaconda on OS X Mavericks. When I try loading cv2 I get an import error (see below). Do you know how to fix this?

>>import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: dlopen(/usr/local/Cellar/opencv/2.4.8.2/lib/python2.7/site-packages/cv2.so,    
2): Library not loaded: /usr/local/lib/libpng15.15.dylib
Referenced from: /usr/local/Cellar/opencv/2.4.8.2/lib/libopencv_highgui.2.4.dylib
Reason: image not found

I am not sure it's relevant, but in /usr/local/lib/ I have libpng16.16.dylib instead of libpng15.15.dylib .

Answer 1

This is the solution I found:

• comment the PYTHONPATH environment in ~/.bash_profile, as suggested by @asmeurer
• install opencv using https://binstar.org/jjhelmus/opencv

作为建议这个问题，我简单地执行固定的这个问题

conda update hdf5

you could also just add it to your PYTHONPATH. here's how: you should be able to get it to load through one of the other (non anaconda) python executables. mine were located at: /usr/bin/python (default system python) and /usr/local/bin/python (brew)

• call the python executable using the full path
• once you successfully import cv2 run: cv2.__file__ this will give you the file's path which you can then take (full directory path not including filename) and add as the first argument to your PYTHONPATH defined in ~/.bash_profile
• after changing the .bash_profile don't forget to run source ~/.bash_profile to make the changes effective
• fire up anaconda python and it should now find cv2
