Hi
I used a simple “I have tea” => “I don’t have tea” formatted dataset for training an XLMR encoder-decoder model using the example provided in the collab.
# set special tokens

roberta_shared.config.decoder_start_token_id = tokenizer.bos_token_id                                             

roberta_shared.config.eos_token_id = tokenizer.eos_token_id

# sensible parameters for beam search

# set decoding params                               

roberta_shared.config.max_length = 64

roberta_shared.config.early_stopping = True

roberta_shared.config.no_repeat_ngram_size = 3

roberta_shared.config.length_penalty = 2.0

roberta_shared.config.num_beams = 4

roberta_shared.config.vocab_size = roberta_shared.config.encoder.vocab_size

But the test set
[“I have it.”,“I love tea”, “I can have coffee.”] =>
[‘I have no it.’, “I’ not love.”, “I can’t have food.”]
Where the model modifies the words in the sentence.
How can I get the negation to be predicted?
