huggingface transformers库中LlamaForCausalLM_llamaforcausallm.from_pretrained

新手入门笔记。

LlamaForCausalLM 的使用示例，这应该是一段推理代码。

from transformers import AutoTokenizer, LlamaForCausalLM
 
model = LlamaForCausalLM.from_pretrained(PATH_TO_CONVERTED_WEIGHTS)
tokenizer = AutoTokenizer.from_pretrained(PATH_TO_CONVERTED_TOKENIZER)
 
prompt = "Hey, are you conscious? Can you talk to me?"
inputs = tokenizer(prompt, return_tensors="pt")
 
# Generate
generate_ids = model.generate(inputs.input_ids, max_length=30)
tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]
