class_docstr: MLP module
  Impl using nn.Linear and activation is GELU, dropout is applied.
  Ops: fc -> act -> dropout -> fc -> dropout
  Attributes:
      fc1: nn.Linear
      fc2: nn.Linear
      act: GELU
      dropout1: dropout after fc1
      dropout2: dropout after fc2
code: def forward(self, x):
      x = self.fc1(x)
      x = self.act(x)
      x = self.dropout1(x)
      x = self.fc2(x)
      x = self.dropout2(x)
      return x

label_desc: Use image node_id 3 for calling the Mlp obj's underlying member method code with example usage: obj.forward(x) and returns: x
