Question about 2.1 conditional generation

[yanamt]

This tutorial uses the webnlg dataset and the preprocessor is for webnlg. However, looking at the preprocessor code(conditional_generation_dataset.py), the e2e and bart preprocessors are also implemented. Could you provide these two implementations?

PROCESSORS = { "webnlg_2017": WebNLGProcessor, "webnlg": WebNLGProcessor, # "e2e": E2eProcessor, # "dart" : DartProcessor, }
