错误分析
1. 错误翻译
原文：[连接超时或网络连接错误]
译文：Connection timeout or network connection error2. 原因分析
这是一个网络连接超时错误，发生在Ollama客户端尝试与模型服务建立连接时。具体表现为：- HTTP请求无法完成，在
socket.recv()操作时超时 - 可能是Ollama服务未启动或无法访问
- 网络配置问题或代理设置错误
3. 解决方案
# 首先检查Ollama服务是否运行
import subprocess
import requests
# 方法1：检查Ollama服务状态
try:
response = requests.get('http://localhost:11434/api/tags', timeout=10)
if response.status_code == 200:
print("Ollama服务正常运行")
else:
print(f"Ollama服务异常，状态码: {response.status_code}")
except requests.exceptions.ConnectionError:
print("Ollama服务未启动")
# 方法2：启动Ollama服务（Windows）
try:
subprocess.run(['ollama', 'serve'], check=True)
except subprocess.CalledProcessError:
print("请手动启动Ollama服务")
# 方法3：添加超时设置到你的代码
response = chat(
model="deepseek-r1:7b",
messages=[
{"role": "user", "content": "你好"}
],
# 添加超时参数
timeout=30 # 设置30秒超时
)4. ️ 预防措施
import requests
from ollama import chat
def safe_chat_call():
try:
# 先检查服务
requests.get('http://localhost:11434', timeout=5)
# 再执行聊天
response = chat(
model="deepseek-r1:7b",
messages=[{"role": "user", "content": "你好"}],
timeout=30
)
return response
except requests.exceptions.ConnectionError:
print("❌ Ollama服务未启动，请运行: ollama serve")
return None
except Exception as e:
print(f"❌ 请求失败: {e}")
return None
