这段代码：

tokens = tokenizer(text, return_tensors='pt')['input_ids'].cuda()
gen_kwargs = {"max_length": 512, "num_beams": 1, "do_sample": True, "top_p": 0.7,
                "temperature": 0.95}
outputs = model.generate(input_ids=tokens, **gen_kwargs)
preds = tokenizer.batch_decode(outputs, skip_special_tokens=True)

用最新的版本decode会报这个错误：
