按照这个方法（https://blog.csdn.net/CAU_Ayao/article/details/83901287）修改没用，反而报新的错误
新错误为：
Traceback (most recent call last):
File “”, line 1, in
File “/home/caffe-master/python/caffe/init.py”, line 1, in
from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver, NCCL, Timer
File “/home/caffe-master/python/caffe/pycaffe.py”, line 13, in
from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver,
ImportError: /home/anaconda3/bin/…/lib/libgio-2.0.so.0: undefined symbol: g_unix_get_passwd_entry

所以以上方法弃用！！！
如果已经用了以上博客方法修改了，就先把对应的“libglib-2.0.so.0”名字改过来

这个问题的解决办法为：重新安装 numpy 和 matplotlib
输入如下命令：
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple numpy1.14.3 matplotlib2.2.3 protobuf
成功安装后，import caffe，一切OK，
折腾了好久，是个大神告诉的，我也不知道为嘛。
