How to integrate with torch data?

[cuge1995]

If a torch data is

a = torch.rand(3)
b = jt.float(a)

this can convert torch data to jittor, but how to convert jittor data to torch ?

Firstly, convert jittor var to numpy. Then you can use it in torch.

a = torch.rand(3)
b = jt.float(a)
c = b.data    # numpy array
d = torch.from_numpy(c)
