How exactly dataloader works with csv file

2

We had recently a similar discussion in this topic.
The DataLoader might take inputs, where __getitem__ and __len__ is defined.
E.g. this code will work:

x = [0, 1, 2]
print(x.__getitem__)
print(x.__len__)

loader = DataLoader(x)
for data in loader:
    print(data)

However, I would still recommend to derive your custom dataset from Dataset and pass it to the DataLoader, as this will give you more control of how __getitem__ and __len__ is implemented.
