Question

我的模型正确形成：

   public static class ViewHolder extends RecyclerView.ViewHolder implements 
   View.OnClickListener {
        private TextView name;
        private TextView comment;
        private TextView number;
        //private TextView date;



        public ViewHolder(View itemView) {
            super(itemView);
            itemView.setOnClickListener(this);

            comment = itemView.findViewById(R.id.textComment);
            name = itemView.findViewById(R.id.textName);
            number = itemView.findViewById(R.id.editTextNum);
            //date = itemView.findViewById(R.id.textDate);

        }

        @Override
        public void onClick(View view) {}
    }


    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View inflatedView = 
    LayoutInflater.from(parent.getContext()).inflate(R.layout
        .row_layout, parent, false);
        return new ViewHolder(inflatedView);
    }

注意，括号已到位。但是当我适应时，我得到以下错误：

model = Sequential()
model.add(Lambda(lambda x:x/255.0 - 0.5, input_shape=(160,320,3)))
model.compile(loss='mse', optimizer='adam')
model.fit(train_generator, samples_per_epoch= len(train_samples), validation_data=validation_generator, nb_val_samples=len(validation_samples), nb_epoch=3)

Traceback (most recent call last): File "modell.py", line 70, in <module> model.fit(train_generator, samples_per_epoch= len(train_samples), validation_data=validation_generator, nb_val_samples=len(validation_samples), nb_epoch=3) TypeError: fit() missing 1 required positional argument: 'y'是一个2D数组

train_generator

我必须失明，因为我无法发现问题。有谁知道为什么train_generator = generator(train_samples, batch_size=32)正在寻找额外的论点？

Answer 1

使用生成器进行训练时，必须使用方法model.fit_generator。

方法fit将始终要求输入（X）和输出/目标（Y）

Keras TypeError：fit（）缺少1个必需的位置参数：'y'
