代码来源于官方文档,做了一些小小的调整:
# -*- coding:utf-8 -*- import tensorflow as tf filename_queue = tf.train.string_input_producer(["file01.csv", "file02.csv"]) reader = tf.TextLineReader() key, value = reader.read(filename_queue) # Default values, in case of empty columns. Also specifies the type of the # decoded result. record_defaults = [[1], [1], [1]] col1, col2, col3 = tf.decode_csv(value, record_defaults = record_defaults) features = tf.stack([col1, col2]) init_op = tf.global_variables_initializer() local_init_op = tf.local_variables_initializer() # local variables like epoch_num, batch_size 可以不初始化local with tf.Session() as sess: sess.run(init_op) sess.run(local_init_op) # Start populating the filename queue. coord = tf.train.Coordinator() threads = tf.train.start_queue_runners(coord=coord) for i in range(5): # Retrieve a single instance: example, label = sess.run([features, col3]) print(example) print(label) coord.request_stop() coord.join(threads)
file01.csv 和 file02.csv 格式一样:
19,3,1 10,2,3 11,3,1 12,4,2 17,5,1 18,6,2 ......
