Description
I get an error when I run this code below.
import os
from jetengine import LLM, SamplingParams
from transformers import AutoTokenizer
model_path = os.path.expanduser("/mnt/yuwanwan/project/SDAR-main/SDAR-1.7B-Chat")
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)
Initialize the LLM
llm = LLM(
model_path,
enforce_eager=True,
tensor_parallel_size=1,
mask_token_id=151669, # Optional: only needed for masked/diffusion models
block_length=4
)
Set sampling/generation parameters
sampling_params = SamplingParams(
temperature=1.0,
topk=0,
topp=1.0,
max_tokens=256,
remasking_strategy="low_confidence_dynamic",
block_length=4,
denoising_steps=4,
dynamic_threshold=0.9
)
Prepare a simple chat-style prompt
prompt = tokenizer.apply_chat_template(
[{"role": "user", "content": "Explain what reinforcement learning is in simple terms."}],
tokenize=False,
add_generation_prompt=True
)
Generate text
outputs = llm.generate_streaming([prompt], sampling_params)
