在keras.sequential中获得很多警告和错误

问题描述

我曾经使用以下功能，但是现在运行它时，升级到Tensorflow 2.3后，我收到许多警告和dtypes令人困惑的通知。我不确定如何修复功能以正确运行keras顺序代码以生成正确的预测。

这是我的实现方式

feature_columns = []

for col in numericColumns:
  col = feature_column.numeric_column(col)
  feature_columns.append(col)

for col in categoricalColumns:
  col = feature_column.indicator_column(feature_column.categorical_column_with_vocabulary_list(col,df_train[col].unique()))
  feature_columns.append(col)

feature_layer = tf.keras.layers.DenseFeatures(feature_columns)


from tensorflow.keras import optimizers

def build_model():
  
  model = keras.Sequential([
    feature_layer,layers.Dense(10,activation='relu'),layers.Dense(1)
  ])

  optimizer = tf.optimizers.RMSprop(learning_rate=lr_schedule)
  model.compile(loss='mse',optimizer=optimizer,metrics=['mse'])
  return model

model = build_model()

这是我调用该函数的方式：

# train the model
history = model.fit(train_ds,validation_data=val_ds,epochs=30)

这是我得到的杂乱的回报，我正在寻找帮助以弄清楚如何修复或重写：
