attention_mask:默认跟输入 input_ids 的shape一样,0代表mask,1代表不mask,被mask掉的token不参与计算注意力权重。 decoder_start_token_id:encoder-decoder架构的模型有可能解码起始符跟编码器不一样(比如[CLS]、)时可指定一个int值。 num_beam_groups (int, optional, defaults to 1) :beam search的时候为了...
While _has_unfinished_sequences 判断当前序列长度和max len来决定是否继续decode model_inputs = self.prepare_inputs_for_generation(input_ids, **model_kwargs) 用来准备输入的内容,这里包括了input_ids,attention_mask,past_key_values等属性, 对应了LlamaForCausalLM类forward中的属性。每一步decode前都要运行。
decode(output_sequence, skip_special_tokens=True) print(f"Generated sequence {i+1}: {output_text}") # 结果 inputs:{'input_ids': tensor([[ 1, 1827, 22172, 304]]), 'attention_mask': tensor([[1, 1, 1, 1]])} query: say hello to Generated sequence 1: say hello to your new ...
attention_mask 使用案例 比如,两个句子如果长度不一样时,我们需要将长的句子剪裁或者对短的句子padding。可以看到,在第一句话的右边的input_ids中添加了0,使其与第二句话的长度相同,而在第一句话对应的attention_mask中,1是应该注意的部分,被padding的部分也是0,告诉模型,我们不对这一部分进行attend。 sequence_a...
According to #7552, the padding tokens will be skipped when calculating the postional_id during generate(), if the corresponding positions are masked out in attention_mask. If I understand this correctly, this would mean that the appeara...
Tasks An officially supported task in theexamplesfolder (such as GLUE/SQuAD, ...) My own task or dataset (give details below) Reproduction use my own model, infer by output_texts = model.generate( input_ids=input_ids, attention_mask=attention_mask, pad_token_id= tokenizer.eos_token_id,...
messages, tokenize=False, add_generation_prompt=True ) model_inputs = tokenizer([text], return_tensors="pt").to(device) print(model_inputs) print(model_inputs['input_ids'].shape) res=model(input_ids=model_inputs['input_ids'])
tl;dr we now prepate a static-shape attention mask in generate. In essence, the same speed up, but less wait time the first time you run it ⌛️ - support for Whisper! Well, this was actually available since v4.43, released two weeks ago, but we haven't communicated m 齐思用户...
