OutOfRangeError（参见上面的回溯）：FIFOQueue '_1_batch/fifo_queue' 已关闭且元素不足（请求 5，当前大小 0）

Question

我不知道如何解决这个问题，这个错误信息对我定位问题没有用。感谢您的帮助！

这里是 e.csv、D.csv 和 F.csv 中的数据

e.csv: 1,2,3
       4,5,6
       7,8,9
D.csv: 11,12,13
       14,15,16
       17,18,19
F.csv: 21,22,23
       24,25,26
       27,28,29

这是我的代码

import tensorflow as tf
import os

file_dir = './KDD2'
fileNameQueue = []
for file in os.listdir(file_dir):
    fileNameQueue.append(file)

print fileNameQueue


filename_queue = tf.train.string_input_producer(fileNameQueue, shuffle=False)

reader = tf.TextLineReader()
key, value = reader.read(filename_queue)

col1,col2,label = tf.decode_csv(value, record_defaults=[[1],[1],[1]])

example = tf.pack([col1,col2])

example_batch, label_batch = tf.train.batch([example, label], batch_size=5)

with tf.Session() as sess:
    coord = tf.train.Coordinator()
    threads = tf.train.start_queue_runners(coord=coord)
    for i in range(10):
        print example_batch.eval()
    coord.request_stop()
    coord.join(threads)

这是错误信息

Answer 1

问题在于文件路径。请提供如下所示的完整路径到文件名队列。

这对我有用：

fileNameQueue.append('/home/****/Desktop/stackoverflow/data/' +file)

希望这会有所帮助。
