安装 tensorflow2.3.1

tensorflow官网：https://tensorflow.google.cn/install

1，安装python3.8.3
2，使用豆瓣镜像源：pip config set global.index-url https://pypi.douban.com/simple
3，pip install tensorflow
4，安装cuda10.2和cudnn （未进行）

• example

import tensorflow as tf
import numpy as np
from tensorflow import keras

model = tf.keras.Sequential([keras.layers.Dense(units=1, input_shape=[1])])
model.compile(optimizer='sgd', loss='mean_squared_error')

xs = np.array([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], dtype=float)
ys = np.array([1.0, 1.5, 2.0, 2.5, 3.0, 3.5], dtype=float)

model.fit(xs, ys, epochs=1000)

print(model.predict([8.0, 9.0, 10.0]))
