self.device in huggingface.py line 210 treated as torch.device but might be a string (#1172)

* self.device in huggingface.py line 210

In huggingface.py line 210, self.device is str and does not have a "type" attribute

* Update huggingface.py

This handles both the case where `self.device` is a `torch.device` and a string

* Update huggingface.py
