1、ImportError:
No module named skimage.io
>>> import caffe
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "caffe/__init__.py", line 1, in <module>
from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver, NCCL, Timer
File "caffe/pycaffe.py", line 15, in <module>
import caffe.io
File "caffe/io.py", line 2, in <module>
import skimage.io
ImportError: No module named skimage.io
解决方案：
缺乏skimage工具箱
pip install scikit-image
2、ImportError: dynamic module does not define module export function (PyInit__caffe)
>>> import caffe

from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, \
ImportError: dynamic module does not define module export function (PyInit__caffe)
>>>
发现是 Python 3.5 导致的，因为版本较高的 Python 和 caffe 不一定兼容；
caffe 官网 (http://caffe.berkeleyvision.org/ ) 上也提示说,
只是较好的支持 caffe 2.7 版本；对于其他的版本，需要自己进行摸索咯。
3、ImportError: No module named google.protobuf.internal
解决方案：
sudo pip install protobuf
4、ImportError: No module named caffe
解决方案：把caffe目录下的python目录，添加到环境变量中
export PYTHONPATH=/work/project/caffe/python:$PYTHONPATH
