Zenodia commented 2 months ago

Problem : I cloned and modified the toy examples here https://github.com/langchain-ai/langgraph-example.git and modified to use image generation ( API call from ai.nvidia.com ) however, whenever my query is using this tool, it kept looping without able to give back an answer.

Could someone please take a look ?

expect output: the agent answer where the generated image is located, it should something similar to the below : Sure, the generated image is saved to this location : output.jpg

Steps to repeat : follow the instruction from official langgraph studio repo https://github.com/langchain-ai/langgraph-studio?tab=readme-ov-file#setup up to Setup clone my modified repo instead https://github.com/Zenodia/langgraphstudio_zcharpy and proceed the steps as usual until set keys in .env

follow this link and obtain NVIDIA_API_KEY https://python.langchain.com/v0.2/docs/integrations/chat/nvidia_ai_endpoints/#setup create .env file and obtain NVIDIA_API_KEY in a terminal also export it , making sure the NVIDIA_API_KEY exist in the environment export NVIDIA_API_KEY then spin up the LangGraph Studio app , in the UI try the following query : make an image of a beautiful town
