Run issue

Thanks for your wonderful work. When I run your code, I face the bug ''' Traceback (most recent call last): File "/home/gyang/data/SAN/detectron2/detectron2/engine/train_loop.py", line 156, in train self.after_step() File "/home/gyang/data/SAN/detectron2/detectron2/engine/train_loop.py", line 190, in after_step h.after_step() File "/home/gyang/data/SAN/detectron2/detectron2/engine/hooks.py", line 556, in after_step self._do_eval() File "/home/gyang/data/SAN/detectron2/detectron2/engine/hooks.py", line 529, in _do_eval results = self._func() File "/home/gyang/data/SAN/detectron2/detectron2/engine/defaults.py", line 453, in test_and_save_results self._last_eval_results = self.test(self.cfg, self.model) File "/home/gyang/data/SAN/detectron2/detectron2/engine/defaults.py", line 602, in test data_loader = cls.build_test_loader(cfg, dataset_name) File "/home/gyang/data/SAN/train_net.py", line 102, in build_test_loader return build_detection_test_loader(cfg, dataset_name) File "/home/gyang/data/SAN/detectron2/detectron2/config/config.py", line 207, in wrapped explicit_args = _get_args_from_config(from_config, *args, *kwargs) File "/home/gyang/data/SAN/detectron2/detectron2/config/config.py", line 245, in _get_args_from_config ret = from_config_func(args, **kwargs) File "/home/gyang/data/SAN/san/data/build.py", line 268, in _test_loader_from_config dataset = get_detection_dataset_dicts( File "/home/gyang/data/SAN/san/data/build.py", line 129, in get_detection_dataset_dicts assert len(dicts), "Dataset '{}' is empty!".format(dataset_name) AssertionError: Dataset 'pcontext_sem_seg_val' is empty! ''' Would you mind helping me to fix this bug?

It seems the program couldn't find the dataset. Did you generate the pcontext dataset?

[ygjwd12345]

yes, following the guide. But I find the generate file name maybe is not correct. the name something like ''' pcontext -train -val '''

[ygjwd12345]

I guess it should be ''' pcontext -pcontext_sem_seg_train -pcontext_sem_seg_val ''' something like that?

[MendelXu]

yes, following the guide. But I find the generate file name maybe is not correct. the name something like ''' pcontext -train -val '''

If it was organized like this, there should be no errors . Have you confirmed that the directory is not empty?

[ygjwd12345]

[ygjwd12345]

I follow to build pcontext dataset. I have confirmed the fold is not empty.

[ygjwd12345]

I fixed this bug. This issue is due to the file's format. The produced data is not consistent with code requirements.

我修复了这个错误。此问题是由于文件的格式造成的。生成的数据与代码要求不一致。

哥，具体是啥原因啊，我也遇到了这个问题
