【调包侠的机器学习】Kaggle手写数字识别2

就嗯叠层数 ``` python def Net(): return tf.keras.models.Sequential([ tf.keras.layers.Conv2D(filters=32, kernel_size=3, activation=tf.keras.activations.relu), tf.keras.layers.Conv2D(filters=32, kernel_size=3, activation=tf.keras.activations.relu), tf.keras.layers.Conv2D(filters=32, kernel_size=3, activation=tf.keras.activations.relu), tf.keras.layers.Conv2D(filters=32, kernel_size=3, activation=tf.keras.activations.relu), tf.keras.layers.MaxPool2D(pool_size=2, strides=2), tf.keras.layers.Dropout(0.2), tf.keras.layers.Conv2D(filters=64, kernel_size=3, activation=tf.keras.activations.relu), tf.keras.layers.Conv2D(filters=64, kernel_size=3, activation=tf.keras.activations.relu), tf.keras.layers.Conv2D(filters=64, kernel_size=3, activation=tf.keras.activations.relu), tf.keras.layers.MaxPool2D(pool_size=2, strides=2), tf.keras.layers.Dropout(0.2), tf.keras.layers.Flatten(), tf.keras.layers.Dense(128, activation=tf.keras.activations.relu), tf.keras.layers.Dense(128, activation=tf.keras.activations.relu), tf.keras.layers.Dropout(0.1), tf.keras.layers.Dense(10, activation=tf.keras.activations.softmax) ]) ```  kaggle （276/1000）
