Here is my script.

import torch
from transformers import (
    AutoModelForCausalLM,
    AutoTokenizer,
    TextStreamer,
)

model_name_or_path='./glm-4-9b-chat'
device = "cuda"

tokenizer = AutoTokenizer.from_pretrained(model_name_or_path,trust_remote_code=True)

model = AutoModelForCausalLM.from_pretrained(
    model_name_or_path,
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    trust_remote_code=True
).to(device).eval()

streamer = TextStreamer(tokenizer, skip_prompt=True, decode_kwargs=dict(skip_special_tokens=True))
gen_kwargs = {"max_length": 2500, "do_sample": True, "top_k": 1, "streamer":streamer, "return_dict_in_generate": True}
past_key_values = None
inputs = None

system_message = "你是一个名为 GLM-4 的人工智能助手。你是基于智谱AI训练的语言模型 GLM-4 模型开发的，你的任务是针对用户的问题和要求提供适当的答复和支持。"
history = [{"role": "system", "content": system_message}]

past_key_values = None

while True:
    query = input("Human: ")
    if len(query.strip()) == 0:
        history = [{"role": "system", "content": system_message}]

        continue
        
    history.append({
        'role': "user",
        "content": query
    })
    inputs = tokenizer.apply_chat_template(history,
                add_generation_prompt=True,
                tokenize=True,
                return_tensors="pt",
                return_dict=True
                )
    inputs = inputs.to(device)
    print(inputs['input_ids'].shape)

    with torch.no_grad():
        print("Assistant:")
        outputs = model.generate(**inputs, **gen_kwargs, past_key_values=past_key_values)
        past_key_values = outputs['past_key_values']
        
        outputs = outputs['sequences'][:, inputs['input_ids'].shape[1]:]
        outputs = tokenizer.decode(outputs[0], skip_special_tokens=True)
        history.append({
            'role': "assistant",
            "content": outputs
        })

The first round chat works fine, but the second round (which has past_key_values passed into model.generate) runs into error:

I tested this script on LLama model and it works well. So maybe you guys could share some suggestions based on ChatGLM modeling implementation.
