text: NameError: name 'IterableWrapper' is not defined

🐛 Bug

Hello, I am trying to load torchtext datasets to reproduce a couple of the tutorials using the new PyTorch MPS support on Mac. After downloading torchdata I get the following error when trying to load any of the datasets in torchtext.datasets:

---------------------------------------------------------------------------
