无法导入caffe

我执行了make pycaffe在 caffe 目录中并且运行良好。我也这样做了：

gsamaras@gsamaras-A15:~/caffe/python$ export PYTHONPATH=$PYTHONPATH:/home/gsamaras/caffe/python

但是当我尝试在另一个项目中导入 caffe 时，我得到了这个：

导入错误：没有名为 caffe 的模块

如何解决这个问题？

另请注意，在caffe的Makefile.config中，有这样一行：

PYTHON_INCLUDE := /usr/include/python2.7 \ <-- correct
/usr/lib/python2.7/dist-packages/numpy/core/include <-- doesn't exist

我的 numpy 版本是 1.11。

Edit:

I found this https://groups.google.com/forum/#!searchin/caffe-users/ImportError%243A%2420No%2420module%2420named%2420caffe/caffe-users/8yRO50dShws/iQOnfOoarCwJ，这表明pip install -U scikit-image，但失败了：

现在我收到这个错误：

导入错误：没有名为 skimage.io 的模块

sudo apt-get install python-skimage为我工作。
