Upon iterating over the dataloader I receive RuntimeError: received 0 items of ancdata. I tried by increasing number of open file descriptors as shown in https://github.com/pytorch/pytorch/issues/973 but to no avail. Can someone please guide how this error could be prevented.
x, (y_l, y_ab) = next(loader)
where loader is defined as following
loader = cycle(train_dataloader)
The complete error traceback is given below.
