error value in batch

[omarkhaled-28]

it gives error when trying to put traindata into batch `batch = next(iter(dataloader['train']))
print("Protein IDs\n ", batch.ids)
print("Sequences\n ", batch.seqs.shape)
print("Evolutionary Data\n ", batch.evolutionary.shape)
print("Secondary Structure\n ", batch.secondary.shape)
print("Angle Data\n ", batch.angles.shape)
print("Coordinate Data\n ", batch.coords.shape)
print("X-ray Resolution\n ", batch.resolutions)
print("Integer sequence")
print("\tShape:", batch.seqs_int.shape)
print("\tEx:", batch.seqs_int[0,:3])

print("1-hot sequence")
print("\tShape:", batch.seqs.shape)
print("\tEx:\n", batch.seqs[0,:3])this is the output once i run it ---------------------------------------------------------------------------

Can you provide more context for your code? The following works for me:

import sidechainnet as scn
dataloaders = scn.load(casp_version=12, casp_thinning=30, with_pytorch="dataloaders")
batch = next(iter(dataloaders['train']))
