+## Usage Code
+
+```python
+import torch
+from transformers import AutoTokenizer, AutoModelForCausalLM
+import numpy as np
+from scipy.special import softmax
+# 选择模型和模型名称（例如，这里使用GPT-2模型）
+model_name = "hkust-nlp/Deita-Complexity-Scorer"
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+model = AutoModelForCausalLM.from_pretrained(model_name)
+
+
+complexity_template = ("You are a helpful assistant. Please identify the complexity score of the following user query. \n##Query: {instruction}  \n##Complexity: ")
+# 输入文本
+input_text = "write a performance review for a junior data scientist"
+
+
+user_input = complexity_template.format(instruction=input_text)
+
+# 将输入文本编码为tokens
+input_ids = tokenizer.encode(user_input, return_tensors="pt")
+
+# 生成文本
+max_length = 512  # 设置生成文本的最大长度
+outputs = model.generate(input_ids, max_length=512, num_return_sequences=1, return_dict_in_generate=True, output_scores=True)
+logprobs_list = outputs.scores[0][0]
