在环境迁移的时候, load和save 经常会出现问题，
这个时候使用latin编码就行

with open(mshelffile, 'rb') as f:
    d = pickle.load(f, encoding='latin1')

# 16是通道数

type()

本来是 type()
现在是 isinstance(x, torch.DoubleTensor),
x.type()

Tensor(1, requires_grad=True)

w = torch.ones(1, requires_grad=True) 
或者是
w = w.requires_grad_()
total = w + z
total.backward()

.data 和 .detach()使用

推荐使用.detach()

0.3.0里面sum区别

tensor.sum()would return a Python number, butvariable.sum()would return a vector of size(1,).

弃用volatile, 使用torch.no_grad()

with torch.no_grad():
	y = x * 2
  
with torch.set_grad_enable(is_train):
  y = x * 2
