Is there any difference between these 2 usage which is shown in below. I mean in the way of computational graph or any difference which is realted to backward?
    def __init__(self, input_dim, hidden_dim, batch_size)
        super(model, self).__init__()

        self.softmax = F.softmax
    
    def forward():
        ...
        out  = self.softmax(out)   vs  out  = F.softmax(out)
