我该如何解决索引超出范围的问题？？？还是这里需要解决的潜在问题是什么？
EDIT1：好..所以这里发生的是我有两个文件夹“ train”和“ test” .. training文件夹包含图像和遮罩，而test文件夹仅包含图像.. apple_dataset.py编写为它在训练和测试文件夹中都寻找masks文件夹。.我想我需要更改代码，使其仅在火车文件夹中而不是测试集中寻找
答案 0 :(得分：0)
错误告诉您您要尝试从列表self.masks中访问索引的所有操作，这些都不存在
问题在此行mask_path = os.path.join(self.root_dir, "masks", self.masks[idx])中。您仅在每次传递idx时都需要检查其值，这样您才能找出问题所在
答案 1 :(得分：0)
通过在“ test”文件夹中创建一个名为“ masks”的虚拟文件夹来解决此问题。只需复制“ train”中的所有文件夹并将其粘贴到所有蒙版中即可。.train和预测脚本不会真正使用它，因此应该这里有任何问题。
还查看this问题，了解需要进行的更多更改
