Test Issue #49

Closed hitsz-zuoqi closed 3 years ago

Hello. I'm try to do training,validate and test. The first two process work well but when I modify the C.is_eval = True. The error will be : *Traceback (most recent call last): File "train.py", line 295, in main() File "train.py", line 82, in main train_loader = get_train_loader(config, Cityscapes, test=config.is_test) File "/opt/data/private/FasterSeg-master/train/dataloader.py", line 52, in get_train_loader train_dataset = dataset(data_setting, "train", train_preprocess, config.batch_size config.niters_per_epoch) File "../tools/datasets/BaseDataset.py", line 23, in init self._file_names = self._get_file_names(split_name) File "../tools/datasets/BaseDataset.py", line 80, in _get_file_names with open(source) as f: FileNotFoundError: [Errno 2] No such file or directory: '/opt/data/private/FasterSeg-master/tools/datasets/cityscapes/cityscapes_train_val_fine.txt'**

I open the dir and find there is no such file, does it mean that I should merge the trainset and valset for training? Could you help me? Thank you!

Hi @hitsz-zuoqi!

Thank you for your interest in our work!

cityscapes_train_val_fine.txt is just a concatenation of cityscapes_train_fine.txt and cityscapes_val_fine.txt

It is for final testing on Cityscapes online leaderboard. Usually when people want to make perditions for the test data and submit online, they train a model with both training and validation images.
