It takes as input a list of tensors, all of the same shape expect for the concatenation axis, and returns a single tensor, the concatenation of all inputs.
layer_concatenate(inputs, axis = -1, ...)A list of input tensors (at least 2). Can be missing.
Concatenation axis.
Standard layer arguments (must be named).
A tensor, the concatenation of the inputs alongside axis axis. If
inputs is missing, a keras layer instance is returned.
