The train process error

[YangBo0411]

First of all, thank you for your outstanding work. When I was training, I encountered the following error:
Traceback (most recent call last):
File "train.py", line 18, in
fix_b = torch.stack([test_loader_b.dataset[i]['A'] for i in range(opt.display_size)]).cuda()
File "train.py", line 18, in
fix_b = torch.stack([test_loader_b.dataset[i]['A'] for i in range(opt.display_size)]).cuda()
File "E:\Github project\santa-main\data\single_dataset.py", line 33, in getitem
A_path = self.A_paths[index]
IndexError: list index out of range

The training command I used was ’python train.py --dataroot=datasets/multidataset --direction=AtoB --lambda_path=0.1 --tag=santa‘

There are four sub folders under the multidataset folder: trainA, trainB, testA, and testB. The images in the folder are unaligned.

Can you tell me what the problem is?

@YangBo0411 did you get a solution? I am facing the same issue.

They use a test dataloader in training procedure, mind your path and dir name.

Do you have a solution? I faced a similar error.

I just replace like below.

# fake = model.translate(data['A'].cuda(), acc_data['A'].cuda())
fake = model.translate(data['A'].cuda())
