class_docstr: Swish activation layer.
  Described in: https://arxiv.org/abs/1710.05941.
  
  Args:
      inplace(`Bool`):
          whether use inplace version.
  Returns:
      (`torch.Tensor`)
          output tensor after activation.
code: def forward(self, x: torch.Tensor) -> torch.Tensor:
      return swish(x, self.inplace)
  
imports: import torch
  from torch import nn
label_desc: Use image node_id 2 for calling the Swish obj's underlying member method code with example usage: obj.forward(x) and returns: swish
