ImportError: No module named cPickle

原因是：

theano要求six的版本在1.9.0以上，以前装了低于该版本的six包。

解决方法：

1.在命令行中输入：python，进入python的命令行模式；

2.依次输入以下命令

import six
print six.__version__
print six.__file__

3.去import的目录下删除跟six有关的文件：six.py six.pyc

4.在命令行中输入：sudo pip install six

done

如果还不行就在4之前再执行一次sudo pip uninstall six
