I am working on someone’s old codebase and I noticed they have used `Variable`

at a lot of places.

I know that `Variable`

has been deprecated.

What changes can I make to the code to replace Variable with Tensor?

```
for n, p in model.named_parameters():
# retrieve the consolidated mean and fisher information.
n = n.replace('.', '__')
mean = getattr(model, '{}_estimated_mean'.format(n))
fisher = getattr(model, '{}_estimated_fisher'.format(n))
# wrap mean and fisher in variables.
# mean = Variable(mean)
# fisher = Variable(fisher)
mean = torch.Tensor(mean, requires_grad=True)
fisher = torch.Tensor(fisher, requires_grad=True)
```

Are the changes in last 4 lines correct? I’ve replaced `Variable(mean)`

with `torch.Tensor(mean, requires_grad=True)`

and so on…

Also I would like to know if wrapping a tensor inside `Variable`

used to detach it from the computation graph? If yes, then I would like to do the same here.
