Hello,

I have successfully passed installation of caffe in Ubuntu 16.04 with python interface. But when I want to Import Caffe in python, I get this error from libcaffe.so.1.0.0-rc3:

ImportError: /home/ali/caffe/python/caffe/../../build/lib/libcaffe.so.1.0.0-rc3: undefined symbol: _ZN2cv8imencodeERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEERKNS_11_InputArrayERSt6vectorIhSaIhEERKSB_IiSaIiEE

After a destructive time of looking around in seek of a solution, I am still left clueless about what the problem is ! Does anyone know what does this mean ? and perhaps the solution to it? I will be so grateful.

Thanks,
Ali

What version of OpenCV did you build Caffe with? Is it in your load library path?

My OpenCV version is 2.4.10.

How can I make sure if it is in my load library path ? Thanks .

I'm getting the same error message as well, but it's for the MATLAB interface.

I have no clue about the error message, but I just wanted to share with you this blog: http://hanzratech.in/2015/07/27/installing-caffe-on-ubuntu.html

I found this to be the best guide for installation of caffe on ubuntu, just check the steps and run "make all" "make test" "make runtest" and "make pycaffe" on ubuntu terminal. Check if all of them work successfully. It should take about 10 mins to test them all.

In my case, this is because I installed opencv through conda and removing opencv from conda solves this problem. I think it is probably because conda's opencv somehow

overwrites ubuntu's default opencv.

Did you try the following?

To your PYTHONPATH, add path to python folder in caffe. This had worked for me.

Hello Ali Kohan,

I am also facing the same problem with the installation. If you solved the problem, could you please guide me.

Thank you

I had the same problem. In my case, just running

conda uninstall opencv

in terminal solves the problem.

Hope this helps.
