shenzhi-wang/Llama3-8B-Chinese-Chat生成乱码怎么解决
from transformers import AutoTokenizer, AutoModelForCausalLM
torch.cuda.empty_cache()
model_id = "./model/Llama3-8B-Chinese-Chat"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)
model.cuda()
model.eval()
messages = [
{"role": "user", "content": "介绍一下你自己"},
]
input_ids = tokenizer.apply_chat_template(
messages, add_generation_prompt=True, return_tensors="pt"
).to(model.device)
outputs = model.generate(
input_ids,
max_new_tokens=8192,
do_sample=True,
temperature=0.6,
top_p=0.9,
)
response = outputs[0][input_ids.shape[-1]:]
print(tokenizer.decode(response, skip_special_tokens=True))
我把模型下载到本地，运行了官方给的代码，打印出来的是乱码，请问是什么问题呢，运行环境：L20，显存48g，以下是生成结果的一部分：
Special tokens have been added in the vocabulary, make sure the associated word embeddings are fine-tuned or trained.

This is a friendly reminder - the current text generation call will exceed the model's predefined maximum length (8192). Depending on the model, you may observe exceptions, performance degradation, or nothing at all.

可以给一下产生这个输出用的prompt吗？还是就是官方样例给的“介绍你自己”？
如果prompt是官方样例给的“介绍你自己”的话，我运行了和你提供的一模一样的代码，运行了两次，都是正常的输出。
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
torch.cuda.empty_cache()
model_id = "./model/Llama3-8B-Chinese-Chat"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.float16)
model.cuda()
model.eval()
messages = [
{"role": "user", "content": "介绍一下你自己"},
]
messages = [
{"role": "user", "content": "Tell me about yourself"},
]
input_ids = tokenizer.apply_chat_template(
messages, add_generation_prompt=True, return_tensors="pt"
).to(model.device)
outputs = model.generate(
input_ids,
max_new_tokens=8192,
do_sample=True,
temperature=0.6,
top_p=0.9,
)
response = outputs[0][input_ids.shape[-1]:]
print(tokenizer.decode(response, skip_special_tokens=True))
以上完整的代码，中英文我都试过了，运行时没有报错但生成的都是乱码，以下是英文prompt“Tell me about yourself”生成结果的一部分：
Special tokens have been added in the vocabulary, make sure the associated word embeddings are fine-tuned or trained.

有没有可能是显卡型号的问题或依赖版本的问题？以下是我的运行配置：
python 3.8.10 , torch 2.0.1,cuda:12.4,显卡：L20（48G显存）
还有个问题就是我在运行上述代码的时候花了5min以上，不知道这个推理时间是否正常，望解答，谢谢！
我运行的就是官方样例“介绍你自己”及其英文“Tell me about yourself”，代码如上
配置补充：transformers 4.40.1
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
model_id = "E:\oobabooga_windows\models\shenzhi-wang_Llama3-8B-Chinese-Chat"

model = AutoModelForCausalLM.from_pretrained(
model_id, torch_dtype=torch.float16, device_map="auto", load_in_4bit=True

messages = [

input_ids = tokenizer.apply_chat_template(

下面是结果:

没有问题。
我也遇到类似问题，AI会一直生成乱码，持续占用gpu，最终卡死ollama
使用的是最新的 wangshenzhi/llama3-8b-chinese-chat-ollama-q4
同样的输入，不一定总能复现，但确实存在
有问题：prompt: <|eot_id|><|start_header_id|>user<|end_header_id|>\n介绍一下你自己<|eot_id|><|start_header_id|>assistant<|end_header_id|>\n
