tensorflow 中import常用包

深度学习常用包 

import os

os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2' #让TensorFlow少打印出一些信息

import matplotlib.pyplot as plt
import tensorflow as tf
from tensorflow import keras
from tensorflow.keras import datasets, layers, optimizers, Sequential, metrics

 在matplotlib可视化中 可以识别出中文，而不报错。

plt.rcParams['font.size'] = 16
plt.rcParams['font.family'] = ['STKaiti']
plt.rcParams['axes.unicode_minus'] = False
