如何在"fit“Tensorflow中禁用检查点

Question

我编写的模块有时(无法预测)会获得新的信息。所以我只有一个例子和一个学习步骤。

classifier = SKCompat(tf.contrib.learn.DNNClassifier(feature_columns=feature_columns, 
                                            hidden_units=[7, 4, 2], 
                                            n_classes=2,
                                            optimizer=tf.train.GradientDescentOptimizer(0.08)
                                                    )
                     )

INFO:tensorflow:Create CheckpointSaverHook.
INFO:tensorflow:Saving checkpoints for 1 into C:\Users\IVAN~1.KAP\AppData\Local\Temp\tmprit6vryq\model.ckpt.
INFO:tensorflow:loss = 0.71007, step = 1

INFO:tensorflow:Restoring parameters from C:\Users\IVAN~1.KAP\AppData\Local\Temp\tmprit6vryq\model.ckpt-1

为每个fit网络创建检查点。这需要3-4秒。我怎样才能禁用它？对我来说太长了
