The following shows the problem and what I have tried:

$ python Python 2.7.13 |Anaconda 4.3.0 (64-bit)| (default, Dec 20 2016, 23:09:15) [GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2 Type "help", "copyright", "credits" or "license" for more information. Anaconda is brought to you by Continuum Analytics. Please check out: http://continuum.io/thanks and https://anaconda.org >>> import caffe >>> import cv2 Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named cv2 >>> import numpy >>> print numpy.__version__ 1.11.3 >>> 

The method I have tried:1. confirmed numpy version;

2. Confirm python version is 2.7

3. check opencv version;

$ dpkg -l | grep libopencv

4. Install opencv by $conda install -c menpo opencv=2.4.11

After step 4 above,cv2 could be imported appropriately but fail to import Caffe. The caffe installation was implemented before and it passed all the check. Like 'make all'; 'make runtest'; and 'make pycaffee'. Now it Failed in 'make all' also 'make pycaffee'. So here it is error message:

Error message of making pycaffe

Since it is lack of ltbb,I install the package

$sudo apt-get install libtbb-dev

Then the problem of 'can't find -ltbb' goes away. But then it complains on the
