Question

尝试将数据提供给模型时，我收到outOfRange错误。我猜测数据永远不会到达队列，因此错误。只是为了测试我正在用一个元组（image，ground_truth）来提供tfrecord。我也试过tensorflow调试器（tfdbg），但它也会抛出相同的错误，我看不到任何tensoeflow值。

Tensorflow版本：1.3

Python版本：3.5.3

Os：Windows10

filename_queue = tf.train.string_input_producer([tfrecord_filename],num_epochs=1)

image_batch, annotation_batch = tf.train.shuffle_batch([resized_image, resized_annotation],
                                                       batch_size=1,
                                                       capacity=10,
                                                       num_threads=1,
                                                       min_after_dequeue=1)

我已尝试在stackoverflow上发布不同的解决方案以获取相同的错误。不幸的是没有什么对我有用如果我应该提供任何其他信息，请告诉我。任何建议表示赞赏。提前谢谢。

Answer 1

我正在为我的机器学习项目创建一个数据集，而且每当我从python以png格式保存图像文件时，我都会遇到上述错误。我使用mat-lab生成了数据集，错误消失了。我仍在调查此问题并尽快发布更新后的答案。同时我希望这会对某人有所帮助。

Answer 2

如果注释图像错误，将显示此错误。请参阅   注释图像矩阵值。它应该是不同的。例如   注释图像矩阵值具有灰色（矩阵值[1 1 1]）   但你的图像不是灰色的（matix值[1 3 6]）。所以检查矩阵值   您的注释图像

如果注释图像不是灰色，则表示队列未填充。这是   错误。

在CamVid_reader_seq def

中的Inputs.py第68行中尝试此代码

label_bytes = tf.image.decode_png(labelValue,1)

注意：1表示将彩色图像转换为灰度

Answer 3

请使用此网址创建注释图像。完成注释图像后，请查看注释图像的矩阵值。
URL：https://github.com/kyamagu/js-segment-annotator

Example:
Originale Annotation Image Matrix Value [1,1,1] but
Your Annotation image have [0,0,1] or [1,0,0] or [0,1,0].

所以你使用我的python脚本和opencv从[0,0,1]转换为相同的值[1,1,1]

def biggest(a, y, z):
    Max = a
    if y > Max:
        Max = y
    if z > Max:
        Max = z
        if y > z:
            Max = y
    return Max
#Input Image
outdir = "sampleimages/sample2.png"
cnt = 0
image = cv2.imread(outdir)

for i in range(0,360):
  for j in range(0,480):
    newvalue = biggest(image[i,j,0],image[i,j,1],image[i,j,2])
    image[i,j,0] = newvalue
    image[i,j,1] = newvalue
    image[i,j,2] = newvalue
    #if image[i,j] == 8:
    #  cnt += 1
#Output Image
cv2.imwrite("sampleimages/sample-gray-2.png",image)

Answer 4

对于这可能有帮助的任何人，我都遇到了同样的错误，这显然是第一个在不同上下文中讨论错误的链接。

感谢 Tensorflow 糟糕的错误信息，这个错误可能是由于以下原因：

TF 记录文件的错误路径
图像形状不匹配
图片文件格式不匹配

OutOfRangeError：RandomShuffleQueue'_2_shuffle_batch / random_shuffle_queue'已关闭且元素不足（请求1，当前大小为0）
