I am trying to port some dataloader codes from codebase 1 to codebase 2.
For codebase 2,  the dataloader was based on ImageFolder, while the dataloader in codebase 1 was something where.  What I did was to replace the getitem of codebase2 with the one from codebase1, and it worked well.
However,  the other part of codebase 2 (which I cannot modify due to some internal policy)  will read the total number of samples by doing len(train_loader), where “train_loader” is the ImageFolder object.
So I am thinking if I can hack it a little bit to modify the attributes of this ImageFolder object “train_loader”, so that len(train_loader) will return the desired value.  I need to do that after this object was created, and I tried “self.samples = []” to see whether len(train_loader) will become 0, but nothing happened.
Could someone provide some guidance on this?  Thanks.
