import skimage.io ImportError: No module named skimage.io（编译pycaffe报错）

错误信息如下：貌似是没有skimage.io模块。在编pycaffe

ImportError: Failed to import test module: test_coord_map
Traceback (most recent call last):
File "/usr/lib/python2.7/unittest/loader.py", line 254, in _find_tests

原因是少了东东：没有安装所谓的skimage.io 模块，所以可以用以下的命令来安装：
1. sudo pip install scikit-image

2.sudo apt-get install python-skimage

以上两种方式任选一个命令输入安装好这个包即可。
