RNNBase
class torch.nn.RNNBase(mode, input_size, hidden_size, num_layers=1, bias=True, batch_first=False, dropout=0.0, bidirectional=False, proj_size=0, device=None, dtype=None)
flatten_parameters()
  Resets parameter data pointer so that they can use faster code
  paths.

  Right now, this works only if the module is on the GPU and cuDNN
  is enabled. Otherwise, it's a no-op.
