I found that Python 3.5 is the cause, because higher versions of Python and caffe are not necessarily compatible.

The official caffe website (http://caffe.berkeleyvision.org/) also suggests that caffe 2.7 is only better supported; for other versions, you need to figure it out yourself.

 

3.ImportError: No module named google.protobuf.internal

Solution:

sudo pip install protobuf

 

4.ImportError: No module named caffe

Solution: Add the python directory under the caffe directory to the environment variables

exportPYTHONPATH=/work/project/caffe/python:$PYTHONPATH
