Problem with downloading the XLNetSequenceClassification pretrained xlnet-large-cased
 I've run this before and it was fine. However, this time, i keep encountering this runtime error. In fact, when i tried to initialize model = XLNetModel.from_pretrained('xlnet-large-cased') - it also gives me the 'negative dimension' error.

`model = XLNetForSequenceClassification.from_pretrained("xlnet-large-cased", num_labels = 2)
model.to(device)`
`---------------------------------------------------------------------------

Hey mate, I've encountered the same issue. How did you solve it?<|||||>I encounter this issue. How can I solve this?<|||||>the problem is when l import xlnet from pytorch_transformers. instead, you should be importing it from the module called 'transformers'
