1.在python官网下载3.5 64位版本的python,并进行安装
2.进行安装,配置环境变量
3.命令行执行pip3 install numpy
4.命令行执行pip3 install tensorflow
5.运行测试
将以下代码保存到test.py中,然后通过python test.py运行
import tensorflow as tf
import numpy as np x_data = np.random.rand(100).astype(np.float32)
y_data = x_data*0.1 + 0.3 Weights = tf.Variable(tf.random_uniform([1], -1.0, 1.0))
biases = tf.Variable(tf.zeros([1])) y = Weights*x_data + biases loss = tf.reduce_mean(tf.square(y-y_data)) optimizer = tf.train.GradientDescentOptimizer(0.5)
train = optimizer.minimize(loss) init = tf.global_variables_initializer() sess = tf.Session()
sess.run(init) for step in range(201):
sess.run(train)
if step % 20 == 0:
print(step, sess.run(Weights), sess.run(biases))
运行结果(我们计算 x*0.1+0.3=y tensorflow通过x与y的值,逼近0.1和0.3)

6.如果出现报错,则安装搜索Microsoft Visual C++ 2015 Redistributable Update 3安装
