Originally created by @chenxizhang on GitHub (Jan 27, 2024).

I am using python 3.11.7 and the latest version of the Ollama pythons SDKs to run the sample code about AsyncClient

from ollama import AsyncClient
import asyncio

async def chat():
    message ={ "role":"user","content":"why people smile?"}
    response = await AsyncClient().chat(model="llama2",message=[message])

asyncio.run(chat())

I got an error as below.

RuntimeError Traceback (most recent call last)
Cell In[7], line 8
5 message ={ "role":"user","content":"why people smile?"}
6 response = await AsyncClient().chat(model="llama2",message=[message])
----> 8 asyncio.run(chat())
