# pip/pip2/pip3
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python2 get-pip.py
python3 get-pip.py

首先我们python3.4 -m pip --version一下
再python3.5 -m pip --version 一下
发现两个pip版本不同，在使用pip3时，使用的其实是python3.4的pip
想用python3.5的pip，只要python3.5 -m pip +命令就可以

weight_decay
为正则项在Loss函数中的系数。如果过拟合，调大这个参数；如果欠拟合，调小这个参数；
准确的说Caffe默认的优化方法是基于mini-batch随机梯度下降的一阶优化算法。
在此基础上还提供了Adagrad，Adadelta，Adam等优化算法。
