Data Loader throwing FileNotFound error After few epochs of training

[ghost]

I've used training command but every time after random number of epochs I've got FileNotFound error from dataloader.Anyone knows the solution? error: epoch: 14 learning rate: 1e-05 [ 0/333] eta: 0:14:51 training_loss: 0.1127 (0.1127) loss_mask: 0.0446 (0.0446) loss_dice: 0.0681 (0.0681) time: 2.6786 data: 0.3379 max mem: 10103 Traceback (most recent call last): File "/content/drive/MyDrive/sam-hq/train/train.py", line 651, in main(net, train_datasets, valid_datasets, args) File "/content/drive/MyDrive/sam-hq/train/train.py", line 360, in main train(args, net, optimizer, train_dataloaders, valid_dataloaders, lr_scheduler,writer) File "/content/drive/MyDrive/sam-hq/train/train.py", line 396, in train for data in metric_logger.log_every(train_dataloaders,1000): File "/content/drive/MyDrive/sam-hq/train/utils/misc.py", line 237, in log_every for obj in iterable: File "/usr/local/lib/python3.10/dist-packages/torch/utils/data/dataloader.py", line 633, in next data = self._next_data() File "/usr/local/lib/python3.10/dist-packages/torch/utils/data/dataloader.py", line 1345, in _next_data return self._process_data(data) File "/usr/local/lib/python3.10/dist-packages/torch/utils/data/dataloader.py", line 1371, in _process_data data.reraise() File "/usr/local/lib/python3.10/dist-packages/torch/_utils.py", line 644, in reraise raise exception FileNotFoundError: Caught FileNotFoundError in DataLoader worker process 0.

This looks like a data path issue. You can check if the image corresponding to the path /content/drive/MyDrive/Iris-and-Needle-Segmentation-3/train/images/SID0615_jpg.rf.8dd4aeb70ce910df9c8716e3af21b2cd.jpg is still there. Or is your google drive disconnected?
