兄弟你解决了吗？
这个问题我也遇到了不过中间的是
AssertionError: Caught AssertionError in DataLoader worker process 0.
最后也是
assert len(label_class) > 0
AssertionError
请问你有解决办法了吗？

非常感谢，已经跑通了，感谢大佬指点 |

你好，我是在coco数据集上碰到了这个问题，请问重新搞数据集具体是指？ |
|
应该是数据集中某几张图片的标注有问题

您好作者，我也遇到了这个问题，我用的是Pascal。不管是用util里面的脚本生成的base_annotation. 还是您给出的直接下载base_annotation的link似乎都没办法解决。总会有不在那20个类的数据，想问问能不能解决呢 |
您好！在pascal数据集上训练train.py时，在验证阶段报错 assert len(label_class) > 0，具体如下：
Traceback (most recent call last):
File "train.py", line 574, in
main()
File "train.py", line 234, in main
loss_val, FBIoU, FBIoU_m, mIoU, mIoU_m, mIoU_b, pIoU = validate(val_loader, model)
File "train.py", line 443, in validate
for i, (input, target, target_b, s_input, s_mask, subcls, ori_label, ori_label_b) in enumerate(val_loader):
File "/root/miniconda3/envs/py38/lib/python3.8/site-packages/torch/utils/data/dataloader.py", line 530, in next
data = self._next_data()
File "/root/miniconda3/envs/py38/lib/python3.8/site-packages/torch/utils/data/dataloader.py", line 1204, in _next_data
return self._process_data(data)

data.reraise()

raise exception

Original Traceback (most recent call last):

File "/root/miniconda3/envs/py38/lib/python3.8/site-packages/torch/utils/data/_utils/fetch.py", line 49, in fetch
data = [self.dataset[idx] for idx in possibly_batched_index]
File "/root/miniconda3/envs/py38/lib/python3.8/site-packages/torch/utils/data/_utils/fetch.py", line 49, in

File "/root/autodl-fs/BAM_project/BAM-main/util/dataset.py", line 252, in getitem
assert len(label_class) > 0
AssertionError
个人判断，是因为验证时，pascal中某张图片的类别只属于sub_list，没有属于sub_val_list中的类别，因此label_class为空，因此提示异常。请问这是什么原因？应该怎么修改？非常感谢！
