A problem when run train.py using my own dataset

[chen-yuxi]

When I run train.py , python3 train.py --model_def config/yolov3-custom.cfg --data_config config/custom.data there is an error that Could not read image '~/PyTorch-YOLOv3/data/custom/images/train2014/ss-214_0x0.jpg'. Could not read image '~/PyTorch-YOLOv3/data/custom/images/train2014/ss-034_0x0.jpg'. Traceback (most recent call last): File "train.py", line 107, in for batchi, (, imgs, targets) in enumerate(tqdm.tqdm(dataloader, desc=f"Training Epoch {epoch}")): File "/home/cyx/.conda/envs/pytorch/lib/python3.7/site-packages/tqdm/std.py", line 1178, in iter for obj in iterable: File "/home/cyx/.conda/envs/pytorch/lib/python3.7/site-packages/torch/utils/data/dataloader.py", line 346, in next data = self._dataset_fetcher.fetch(index) # may raise StopIteration File "/home/cyx/.conda/envs/pytorch/lib/python3.7/site-packages/torch/utils/data/_utils/fetch.py", line 47, in fetch return self.collate_fn(data) File "/home/cyx/PyTorch-YOLOv3/utils/datasets.py", line 130, in collate_fn paths, imgs, bb_targets = list(zip(*batch)) ValueError: not enough values to unpack (expected 3, got 0) Anyone can help me?

Please check the paths in youre .txt file. The leading / indicates an absolute path and I don't think your repository is located in your root directory.

[chen-yuxi]

Thank you. It works.

Do you have the wrong file path? I had the same problem

[chen-yuxi]

In the train.txt and valid.txt , we must use absolute path, not relative path.
