OutOfRangeError(请参阅上面的回溯):FIFOQueue'_1_batch/fifo_queue'已关闭且元素不足(请求5，当前大小为0) [英] OutOfRangeError (see above for traceback): FIFOQueue '_1_batch/fifo_queue' is closed and has insufficient elements (requested 5, current size 0)

问题描述

我不知道如何解决此问题，此错误消息对我定位问题没有用.感谢您的帮助！

i don't know how to solve this problem, this error message is useless for me to locate the problem. Thanks for helping!

这是e.csv，D.csv和F.csv中的数据

here is the data in e.csv, D.csv and F.csv

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

here is my code

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)

这是错误消息

推荐答案

问题出在文件路径上.请提供如下所示的fileName Queue的完整路径.

Problem is with filepaths. Please provide complete paths as shown below to fileName Queue.

这对我有用:

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

希望这会有所帮助.
