EOFError in PyTorch loader

#1

I am trying to load a dataset using the pytorch’s data loader. When I run

for batch_idx, (data, label) in enumerate(loader):
    <rest of the code>

I get the following error:

Exception has occurred: EOFError (note: full exception trace is shown but execution is paused at: )
Ran out of input
File “”, line 1, in (Current frame)

I don’t know what’s wrong. The same dataset runs elsewhere, and I can also see some values in loader.dataset.data.shape and loader.dataset.label with correct values.

Any help?

#2

The EOFError is usually raised by the data loading. Does the stacktrace show more information which line of code is failing?

#3

There is no more information unfortunately, and no info about which line is causing the error. However, when I debug and try to get the first batch of (data, label) in the for loop, it causes this error.
