Google Colab中的运行时自动重启错误

Question

hi i want to use google colab to train a model for my classification but when i start training after a few seconds, it says 'Runtime died. Automatically restarting.'

my model is:

model=keras.Sequential([
    keras.layers.Flatten(input_shape=(230, 320, 3)),
    keras.layers.Dense(32,activation=tf.nn.relu),
    keras.layers.Dense(10,activation=tf.nn.relu),
    keras.layers.Dense(5,activation=tf.nn.softmax),
])
opt=tf.train.AdamOptimizer()
model.compile(loss='sparse_categorical_crossentropy',optimizer=opt,metrics=['accuracy'])

and training code is :

model.fit(train_data,train_labels,epochs=25,validation_split=0.2)

any suggestion?

所以我解决了这个问题，错误是因为我选择了一个图像通道，而当我选择3个通道时，问题就消失了。
