pytorch torchsummary 报错argument 0 is not a Variable,: Input type (torch.cuda.FloatTensor) and weigh

首先安装torchsummary

pip3 install torchsummary

执行如下代码：

from torchvision import models
model = models.vgg16()
torchsummary.summary(model, (3, 224, 224))

报错：argument 0 is not a Variable

解决方法是：pytorch版本太老

更新版本：pip3 install --upgrade torch

再次执行又报错：RuntimeError: Input type (torch.cuda.FloatTensor) and weight type (torch.FloatTensor) should be the same

解决方法是模型在cuda上了：

from torchvision import models
model = models.vgg16()
torchsummary.summary(model.cuda(), (3, 224, 224))

安装完torch1.0之后，在import torch时报错：

ImportError: libcurand.so.9.1: cannot open shared object file: No such file or directory

解决办法：执行如下命令
