运行”Qwen-7B-Chat“时，报错too many 500 error responses'

我在尝试本地跑通义千问Qwen-7B-Chat的快速使用（Quickstart），但是模型多次下载失败后，再次执行程序会遇到如下报错信息。不知道该如何解决。

运行程序

# 官方示例：https://modelscope.cn/models/qwen/Qwen-7B-Chat/summary

from modelscope import AutoModelForCausalLM, AutoTokenizer
from modelscope import GenerationConfig

tokenizer = AutoTokenizer.from_pretrained("qwen/Qwen-7B-Chat", revision = 'v1.0.1',trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("qwen/Qwen-7B-Chat", revision = 'v1.0.1',device_map="auto", trust_remote_code=True).eval()

报错信息如下：

urllib3.exceptions.ResponseError: too many 500 error responses

The above exception was the direct cause of the following exception:
