```auto
class A(nn.Module):
    def __init__ (self):
        super(A,self). __init__ ()
        self.p = nn.Parameter(torch.randn(1))

```

In def forward when I call `print(self.p.shape, self.p)`, it is returning :

```auto
torch.Size([0]) Parameter containing:
tensor([], requires_grad=True)

```

So, self.p is not initialized. How to initialize this ? Please help.

It works for me.

```auto
import torch
import torch.nn as nn

class A(nn.Module):
    def __init__ (self):
        super(A,self). __init__ ()
        self.p = nn.Parameter(torch.randn(1))
        
    def forward(self):
        print(self.p.shape, self.p)
        
a = A()
a()

```

which prints out:

torch.Size([1]) Parameter containing:  
tensor([-0.3897], requires\_grad=True).

I dunno what exactly the error was, it didn’t run in the beginning , now its running. I’m getting errors if I dont remove `A,self` inside `super()`. Any idea why.

What kind of errors are you seeing if you keep `super(A, self). __init__ ()` and which Python version are you using?  
The arguments were only necessary in Python2, if I’m not mistaken, but I haven’t seen it’s raising an error in Python3.
