最近，心血来潮搞一搞tensorflow,看着《tensorflow实战》码了几个简单的小网络，自以为蛮简单啊，当自己开始从头开始构建自己网络时候，就开始怀疑人生了。自己的数据读取都是一个大问题，今天解决了使用tensorflow读取csv文本数据，写到博客做个笔记。

capacity = mini_after_dequeue+3*batch_size

example_batch,label_batch = tf.train.shuffle_batch([features[0],features[1]],batch_size = batch_size,capacity=capacity,min_after_dequeue=mini_after_dequeue)

features = [features]

W1=tf.Variable(tf.truncated_normal([6,1]))

result = tf.matmul(example_batch,W1)**

with tf.Session() as sess:
init =tf.global_variables_initializer()
sess.run(init)
# Start populating the filename queue.
coord = tf.train.Coordinator()
threads = tf.train.start_queue_runners(coord=coord)
try:
for iter in range(5):
print sess.run([example_batch,label_batch])
print sess.run(features)
except tf.errors.OutOfRangeError:
print ‘Done training – epoch limit reached’
finally:
coord.request_stop()

最后

以上就是机灵胡萝卜为你收集整理的tensorflow--数据读取篇features = [features]W1=tf.Variable(tf.truncated_normal([6,1]))result = tf.matmul(example_batch,W1)**的全部内容，希望文章能够帮你解决tensorflow--数据读取篇features = [features]W1=tf.Variable(tf.truncated_normal([6,1]))result = tf.matmul(example_batch,W1)**所遇到的程序开发问题。
