Python - 读取pickle数据的索引 [英] Python - Reading the indices of pickled data

问题描述

拥有以下腌制数据：

[array([[[148, 124, 115],
        [150, 127, 116],
        [154, 129, 121],
        ..., 
        [159, 142, 133],
        [159, 142, 133],
        [161, 145, 142]]]), array([1])]

我能够检索数据和标签，如下所示：

I was able to retrieve the data and label, as follows:

data = batch[0]
labels = batch[1]

在这种情况下，在为数据和标签分别创建 print 时，我有以下输出：

In which case, I had the following output when making a print for both data and label, separately:

[[[148 124 115]
  [150 127 116]
  [154 129 121]
  ...,
  [159 142 133]
  [159 142 133]
  [161 145 142]]]
[1]

当我的批处理文件现在看起来如下，因为我添加了一个新图像，我没有弄清楚如何读取第二个图像及其标签。我似乎无法理解这里如何将pickle文件编入索引：

When my batch file now looks as follows as I added a new image, I didn't figure out how to read the 2nd image and its label. It seems I cannot understand how the pickled file is indexed here:

[array([[[148, 124, 115],
        [150, 127, 116],
        [154, 129, 121],
        ..., 
        [159, 142, 133],
        [159, 142, 133],
        [161, 145, 142]],

       [[165, 136, 145],
        [176, 137, 141],
        [178, 138, 144],
        ..., 
        [199, 163, 171],
        [202, 163, 167],
        [200, 158, 163]]]), array([1, 1])]

如何迭代这样的腌制文件？该文件是如何编入索引的？特别是我想添加更多图像及其标签。

How can I iterate through such pickled file? How is the file indexed? Especially that I would like to add more images along with their labels.

谢谢。

推荐答案

你的数据被腌制的方式，两个图像最终在同一个数组中，因此你必须相应地索引：

The way your data is pickled, the two images end up in the same array and thus you have to index accordingly:

batch[0][0] #this will give the first image
batch[0][1] #this will give the second image
batch[1][0] #this will give the first label
batch[1][1] #this will give the second label
