class_docstr: Original Implementation of the GELU activation function in Google BERT repo when initially created. For
  information: OpenAI GPT's GELU is slightly different (and gives slightly different results): 0.5 * x * (1 +
  torch.tanh(math.sqrt(2 / math.pi) * (x + 0.044715 * torch.pow(x, 3)))) This is now written in C in nn.functional
  Also see the Gaussian Error Linear Units paper: https://arxiv.org/abs/1606.08415
code: def __init__(self, use_gelu_python: bool = False):
      super().__init__()
      if use_gelu_python:
          self.act = self._gelu_python
      else:
          self.act = nn.functional.gelu

label_desc: Use image node_id 1 to create a new GELUActivation object from inherited base classes: nn with example: obj = GELUActivation(use_gelu_python)
