docs: Return a variable of all 0s, with the same shape as the input variable. Note that this is dynamic:
  if the input shape changes in later execution, the returned variable's shape will also be updated
  
  @param name  Name of the new SDVariable
  @param input Input SDVariable
  @return A new SDVariable with the same (dynamic) shape as the input
