I clone caffe from github, make it and make pycaffe with no error. Now I can import caffe in terminal.
But when I run the script 'demo.py', one error comes out by tips:
...from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver... import error libprotobuf.so.8 cannot open shared object file...
P.S. My OS is ubuntu 16.04, libprotobuf.so.9 is in the system, but not libprotobuf.so.9
what shall I do to fix this?
