TensorFlow random_shuffle_queue 关闭且元素不足 [英] TensorFlow random_shuffle_queue is closed and has insufficient elements

问题描述

我正在通过此处 来自 tfrecords(由 this 转换)

I'm reading batch of images by getting idea here from tfrecords(converted by this)

我的图像是 cifar 图像，[32, 32, 3]，正如您在读取和传递图像时所看到的，形状是正常的 (batch_size=100)

My images are cifar images, [32, 32, 3] and as you can see while reading and passing images the shapes are normal (batch_size=100)

据我所知，日志中提到的 2 个最显着的问题是

the 2 most notable problems stated in the log, as far as I know is

1. 12228 的形状，我不知道从哪里得到的.我所有的张量要么是 [32, 32, 3] 的形状，要么是 [None, 3072]
2. 样品用完

计算状态:超出范围:RandomSuffleQueue '_2_input/shuffle_batch/random_shuffle_queue' 已关闭且元素不足(请求 100，当前大小为 0)

我该如何解决这个问题?

How can I solve this?

日志:

1- image shape is  TensorShape([Dimension(3072)])
1.1- images batch shape is  TensorShape([Dimension(100), Dimension(3072)])
2- images shape is  TensorShape([Dimension(100), Dimension(3072)])

推荐答案

我遇到了类似的问题.在网上挖掘，结果发现如果你使用一些 num_epochs 参数，你必须初始化所有的 local 变量，所以你的代码最终应该是这样的:

I had a similar problem. Digging around the web, it turned out that if you use some num_epochs argument, you have to initialize all the local variables, so your code should end up looking like:

with tf.Session() as sess:
    sess.run(tf.local_variables_initializer())
    sess.run(tf.global_variables_initializer())
    coord = tf.train.Coordinator()
    threads = tf.train.start_queue_runners(coord=coord)

    # do your stuff here

    coord.request_stop()
    coord.join(threads)

如果您发布更多代码，也许我可以更深入地研究它.与此同时，HTH.

If you post some more code, maybe I could take a deeper look into it. In the meantime, HTH.
