설치 및 동작 과정 캡쳐

* install tensorflow
관리자 권한으로 실행안해서 에러발생됨.

관리자 권한으로 실행후 python upgrade 진행

* mnist 로딩
from tensorflow.examples.tutorials.mnist import input_data
mnist = input_data.read_data_sets("/tmp/data/", one_hot=True)

코딩

x_data = np.random.rand(100).astype(np.float32)
y_data = x_data*0.1+0.3

W = tf.Variable(tf.random_uniform([1],-1.0,1.0))
b = tf.Variable(tf.zeros([1]))
y = W* x_data + b

loss = tf.reduce_mean(tf.square(y-y_data))
optimizer = tf.train.GradientDescentOptimizer(0.5)
train = optimizer.minimize(loss)

init = tf.global_varables_initializer()

sess = tf.Session()
sess.run(init)

for step in range(201):
    sess.run(train)
    if step % 20 == 0:
        print(step, sess.run(W), sess.run(b))
