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

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

File "/home/wangxiao/Downloads/project/caffe-master/python/caffe/__init__.py", line 1, in <module>

from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver

File "/home/wangxiao/Downloads/project/caffe-master/python/caffe/pycaffe.py", line 13, in <module>

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
