 def loss(self, args, X):
     if type(args) is not list:
         args = args_from_vector(args, self.params)
     # Reshape theta -> args
     args += [X]
     # Compute gradient from args
     loss = self._loss(*args)
     return loss

Example #2

 def f_df(self, args, X):
     if type(args) is not list:
         args = args_from_vector(args, self.params)
     args += [X]
     # Compute gradient from args
     #grad = vector_from_args(self.grads(*args))
     grad = self.grads(*args)
     loss = self._loss(*args)
     return loss,grad
