Pytorch使用多GPU

在caffe中训练的时候如果使用多GPU则直接在运行程序的时候指定GPU的index即可，但是在Pytorch中则需要在声明模型之后，对声明的模型进行初始化，如：
cnn = DataParallel(AlexNet())
之后直接运行Pytorch之后则默认使用所有的GPU，为了说明上述初始化的作用，我用了一组畸变图像的数据集，写了一个Resent的模块，过了50个epoch，对比一下实验耗时的差别，代码如下：

作为对比实验，我们同时把ResNet的声明方式修改为
resnet = ResNet(ResidualBlock, [3, 3, 3])
其余不变，再运行程序的时候不指定GPU，直接python resnet.py,在声明DataParallel时，运行耗时结果如下：
('time used:', 17124.861335999998)，watch -n 1 nvidia-smi确实显示占用两块GPU
在不声明DataParallel时，实验运行结果耗时如下：
('time used:', 30318.149681000003)，watch -n 1 nvidia-smi确实显示占用一块GPU
可以看出，在声明DataParallel时时间压缩了近一半，所以在声明DataParalle是使用多GPU运行Pytorch的一种方法。
官方的doc也给出了多GPU使用的例子以及部分数据在GPU与部分数据在CPU上运行的例子
以下是两组实验结果的输出：
