Pasted the error below. gopi@gp:~/crfasrnn/python-scripts$ python crfasrnn_demo.py Traceback (most recent call last): File "crfasrnn_demo.py", line 31, in import caffe File "../caffe/python/caffe/init.py", line 1, in from .pycaffe import Net, SGDSolver File "../caffe/python/caffe/pycaffe.py", line 13, in from ._caffe import Net, SGDSolver ImportError: /home/gopi/crfasrnn/python-scripts/../caffe/python/caffe/../../build/lib/libcaffe.so: undefined symbol: _ZN2cv8imencodeERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEERKNS_11_InputArrayERSt6vectorIhSaIhEERKSB_IiSaIiEE

My system details: Ubuntu 16.04 with nvidia gtx 1070 GPU.

FYI, also tried Uncommenting the line: WITH_PYTHON_LAYER := 1 as per https://github.com/BVLC/caffe/issues/3834 & did make again, but no improvement

I solved it using default python instead of anaconda. gopi@gp:~/crfasrnn/python-scripts$ /usr/bin/python crfasrnn_demo.py
