如何防止transformer generate函数产生某些词？

Question

我有以下代码：

from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("t5-small")
model = T5ForConditionalGeneration.from_pretrained("t5-small")

input_ids = tokenizer("The <extra_id_0> walks in <extra_id_1> park", return_tensors="pt").input_ids

sequence_ids = model.generate(input_ids)
sequences = tokenizer.batch_decode(sequence_ids)
sequences

目前它产生这个：

['<pad><extra_id_0> park offers<extra_id_1> the<extra_id_2> park.</s>']

有没有办法阻止生成器生成不在列表中的某些词（例如 park、offer）？
