Layer that subtracts two inputs.
It takes as input a list of tensors of size 2, both of the same shape, and returns a single tensor, (`inputs[[1]] - inputs[[2]]``), also of the same shape.

layer_subtract(inputs, batch_size = NULL, dtype = NULL, name = NULL,
  trainable = NULL, weights = NULL)Arguments
| inputs | A list of input tensors (exactly 2). | 
| batch_size | Fixed batch size for layer | 
| dtype | The data type expected by the input, as a string ( | 
| name | An optional name string for the layer. Should be unique in a model (do not reuse the same name twice). It will be autogenerated if it isn't provided. | 
| trainable | Whether the layer weights will be updated during training. | 
| weights | Initial weights for layer. | 
Value
A tensor, the difference of the inputs.
