1.运行TensorFlow2.0时的warning

Warning提示：

This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN)to use the following CPU instructions in performance-critical operations:  AVX2 FMA
To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.

XLA service 0x7f87c32cdd00 initialized for platform Host (this does not guarantee that XLA will be used). Devices:StreamExecutor device (0): Host, Default Version

解决方案：

import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'

2.TensorFlow保存模型时的warning

执行tf.keras.models.save_model时，

Warning提示：

Model.state_updates (from tensorflow.python.keras.engine.training) is deprecated and will be removed in a future version.
Instructions for updating:
This property should not be used in TensorFlow 2.0, as updates are applied automatically.

Layer.updates (from tensorflow.python.keras.engine.base_layer) is deprecated and will be removed in a future version.
Instructions for updating:
This property should not be used in TensorFlow 2.0, as updates are applied automatically.

解决方案：
