generated_output in usage_example.py doesn't contain a valid output about sled HOT 1 CLOSED

Hi,
The model loaded in usage_example.py is the pertained facebook/bart-base model wrapped with SLED. As it was not fine-tuned on anything, it indeed mostly just generates output identical to the input as it was trained to Denise the input. The usage example just gives an example how one can load and generate using a model, you should fine-tune on your task before using it. Alternatively, you can load a fine-tuned SLED checkpoint from the hub. For example, you can try loading BART-base-SLED fine-tuned on contract NLI with tau/bart-base-sled-contractnli

from sled.
