Load EMNIST dataset from within the Pytorch

I'm working on EMNIST dataset and want to load it from PyTorch, but it returns a strange error as:

RuntimeError: File not found or corrupted.

Here's how i have tried to load the dataset:

trainset = torchvision.datasets.EMNIST(root="emnist",                                   split="letters",                                   train=True,                                   download=True,                                   transform=transforms.ToTensor())

What might be wrong?
