Getting error in chapter 4, DataLoader error.

[hiteshmaurya99]

Here is my code.
from torch.utils.data import DataLoader

train_dataloader = DataLoader(dataset = train_data,
batch_size = 1,
shuffle = True
num_workers = 1)
test_dataloader = DataLoader(dataset = test_data,
batch_size = 1,
shuffle = False,
num_workers = 1)
train_dataloader, test_dataloader
##This works exactly as the vedio.

img, label = next(iter(train_dataloader))
img, label
##This part is the problem and raises error:

TypeError: Caught TypeError in DataLoader worker process 0.
Original Traceback (most recent call last):

look i had the same error "TypeError: Caught TypeError in DataLoader worker process 0." but somehow was the issue in the data_transform
because i used trivailaagumanted(magnitude_bins=1). Value 1 had the issue
