response = agent.chat("what is today's date?")

I found this code online and am trying to run it

I tried pip install llama_index but am getting

from llama_index.agent import ReActAgent
ImportError: cannot import name 'ReActAgent' from 'llama_index.agent' (unknown location)

Anyone know if the imports changed?

Plain Text

from llama_index.llms.ollama import Ollama
from llama_index.core.agent import ReActAgent
from llama_index.core.tools import FunctionTool

You'll also need to install any integrations, i.e. pip install llama-index-llms-ollama

from llama_index.llms import Ollama
ImportError: cannot import name 'Ollama' from 'llama_index.llms' (unknown location)

ok thank you! do you know how to fix this last one?

Need to install and update the import as above

LLucas

oops thanks I got it now,

Im scratching my head with this one

nvm I got it, I had the run llm running

LLucas

File "C:\Users\lhenry\AppData\Local\Programs\Python\Python312\Lib\site-packages\httpx_transports\default.py", line 232, in handle_request
with map_httpcore_exceptions():
File "C:\Users\lhenry\AppData\Local\Programs\Python\Python312\Lib\contextlib.py", line 158, in exit
self.gen.throw(value)
File "C:\Users\lhenry\AppData\Local\Programs\Python\Python312\Lib\site-packages\httpx_transports\default.py", line 86, in map_httpcore_exceptions
raise mapped_exc(message) from exc
httpx.ReadTimeout: timed out

would running too slow cause this time out?

LLucas

it seems ot work with tinyllama

LLogan M

increase the request timeout

LLogan M

llm = Ollama(model="mistral", request_timeout=3600)

LLucas

File "C:\Users\lhenry\AppData\Local\Programs\Python\Python312\Lib\site-packages\llama_index\core\agent\react\step.py", line 412, in _get_response
raise ValueError("Reached max iterations.")
ValueError: Reached max iterations.

is there a similar way to up the max iterations?

LLucas

nvm got it
