报错分析报告
1. 错误翻译
原文:Max retries exceeded with url: /sentence-transformers/all-MiniLM-L6-v2/resolve/main/modules.json (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f7abef2f0d0>: Failed to establish a new connection: [Errno 101] Network is unreachable'))
译文:尝试URL的最大重试次数已超出:/sentence-transformers/all-MiniLM-L6-v2/resolve/main/modules.json (原因是新连接错误:无法建立新连接:[错误号101] 网络不可达)
2. 原因分析
根本原因:网络连接问题导致的HuggingFace模型下载失败- 错误类型:网络不可达(Network is unreachable)
- 发生位置:尝试从huggingface.co下载sentence-transformers模型文件时
- 具体上下文:urllib3库在建立HTTPS连接时遇到网络障碍
3. 解决方案
方案一:设置代理(如果处于受限网络环境)
import os
os.environ['HTTP_PROXY'] = 'http://your-proxy-server:port'
os.environ['HTTPS_PROXY'] = 'https://your-proxy-server:port'
方案二:使用镜像源
from sentence_transformers import SentenceTransformer
# 使用国内镜像源(如果可用)
model = SentenceTransformer('all-MiniLM-L6-v2',
cache_folder='/path/to/local/cache')
方案三:增加重试和超时设置
from sentence_transformers import SentenceTransformer
import requests
# 自定义会话以增加重试
session = requests.Session()
adapter = requests.adapters.HTTPAdapter(max_retries=3)
session.mount('https://', adapter)
try:
model = SentenceTransformer('all-MiniLM-L6-v2',
request_session=session,
timeout=30)
except Exception as e:
print(f"下载失败: {e}")
4. ️ 预防措施
最佳实践建议:
python -c "from sentence_transformers import SentenceTransformer; SentenceTransformer('all-MiniLM-L6-v2')"
import urllib.request
def check_network():
try:
urllib.request.urlopen('https://huggingface.co', timeout=5)
return True
except:
return False
推荐工具:
ping huggingface.co检查网络连通性
