Are there any methods to get the conv module input params from the 'grad_fn' in the newest version of pytorch?

for example,in pytorch version 0.2,

modle = nn.Conv2d(in_channels=3 out_channels=32, kernel_size=3,stride=2, padding=1, dilation=1, bias=False))
y = modle(x)

if I get the result y, I can get the input param’s values like kernel_size、stride、padding value use y.grad_fn.kernel_size,y.grad_fn.padding,……

but in pytorch version 0.3,the grad_fn(which has type ‘thnnconv2dbackward’) has not attribute like kernel_size, padding……

So,how could I get these input params’s values in the newest version of pytorch?

Any solution on this?
