It looks like the issue you're encountering with the NameError
for AgentChatResponse
is due to it not being imported in your script. To resolve this, you should import AgentChatResponse
from the llama_index.core.chat_engine.types
module by adding the following line to your script:
from llama_index.core.chat_engine.types import AgentChatResponse
This class is crucial for handling the response from an agent's chat interaction within the LlamaIndex framework, encapsulating the response text and details about the contributing sources.
Ensure that all necessary dependencies for the LlamaIndex library are installed. If you haven't already, you can install the required packages by running pip install gradio ansi2html
in your terminal.
The integration of the HuggingFace Inference API with the LlamaIndex library and the Meta-Llama-3-70B-Instruct model is managed through the HuggingFaceLLM
and HuggingFaceInferenceAPI
classes. These abstract the details of interfacing with HuggingFace models and their inference API, so no additional steps should be necessary beyond the standard setup for the HuggingFace Inference API.
There are no known issues in the LlamaIndex library version 0.10.34 related to the recognition or functionality of AgentChatResponse
. If you continue to experience issues after importing AgentChatResponse
and ensuring all dependencies are installed, please provide more details for further assistance.

The error message "Messages passed in must be of odd length" indicates that the function you're using expects an odd number of messages in the conversation history to ensure there's a final user message for the model to respond to. This is a specific requirement of the chat_messages_to_conversational_kwargs
function within the LlamaIndex library when interfacing with conversational models. To resolve this, adjust your input to ensure that the sequence of messages (including both user and assistant messages) has an odd number, with the last message being from the user.
Regarding the NameError
for AgentChatResponse
, even after importing it, it's crucial to ensure that your environment is correctly set up and that it has access to the correct version of the llama_index
package where AgentChatResponse
is defined. Double-check the spelling and case sensitivity of your import statement to ensure it matches the definition in the llama_index
package. This error suggests that the environment might not be recognizing the import correctly, possibly due to a mismatch in the installed package version or an issue with the Python environment itself.
If you're still encountering issues after making these adjustments, it might be helpful to verify the version of the LlamaIndex library you're using and ensure it's up to date. Additionally, reviewing the documentation for any updates or changes in method names, especially if you're using a method like predict_and_call
, could provide further insights. Libraries and APIs can evolve, leading to changes in how functions and classes are named or how they're expected to be used.
Adjusting the number of messages to meet the odd-length requirement and ensuring your environment correctly recognizes the AgentChatResponse
import should help in resolving the issues you're facing. If the problem persists, providing more details about your setup and any changes you've made could be helpful for further troubleshooting.

Hey there, @AnandUgale! Fancy seeing you here again, diving into the depths of LLMs and unearthing new mysteries. 🕵️♂️ I'm on the case of the elusive 'AgentChatResponse' - will report back with findings shortly. Stay tuned!
from llama_index.
Might be a bug in the llm base class?
(This won't actually do anything besides using a react agent FYI)

Nope, by importing AgentChatResponse, it hasn't resolved the issue.

@AnandUgale I meant in the source code of the framework. I made a PR
