打印模型参数信息
在python3环境下安装torchsummary

from torchsummary import summary
import torchvision.models as models
model = models.resnet152()
model = model.cuda()
summary(model, input_size=(3,224,224), batch_size=-1, device='cuda')

计算模型FLOPs
代码详见：https://github.com/TangShengqin/pytorch_learn/blob/master/model_flops.py
其中，multiply_adds = True会同时累计加法和乘法的计算量。
