Problem when importing caffe in python 3.5.2

[len...@hotmail.com]

The operating system I am using is Ubuntu 16.04. I changed 4 places in Makefile.config.

CPU_ONLY := 1

OPENCV_VERSION := 3

PYTHON_LIBRARIES := boost_python3 python3.5m
PYTHON_INCLUDE := /usr/include/python3.5m \
                /usr/local/lib/python3.5/dist-packages/numpy/core/include

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial

Then I followed the official guide for the other steps. However, when I tried to import caffe in python 3.5.2 afterwards, I received the following error.

Any clue how I can solve this? Thanks.
