测试自己建立的数据集时遇到了一些问题

[hanyi997]

作者您好，我参考veri776数据集的命名格式重新建立了query和gallery，并按照readme的步骤重新生成了pkl文件和解析后的mask文件。但进行测试时遇到了以下错误：

请问解决了吗，我也是这个问题

出现这个错误是因为query所属的id没有出现在gallery里，我直接让他报错了。可以先过滤一遍数据，确保gallery中至少存在一张query数据。否则测试出来的结果没有意义。

你好，请问运行了python generate_masks.py这个文件后，生成的图片是全黑的是不是有问题呢？

是正常的。因为我用1，2，3来代表不同的mask值，反映到图像里都是黑白的（最大255）。想看实际的形状可以用matplotlib画一下。
