Very sparse output from LLMGraphTransformer when switching ChatOllama library from langchain_community.chat_models to langchain_ollama

[csaiedu]

I am not sure if it's a compatibility issue but when using LLMGraphTransformer in LangChain with Ollama and Llama3.1,the switch over from

from langchain_community.chat_models import ChatOllama

to

from langchain_ollama import ChatOllama

leads to sparse results. Does anyone using LLMGraphTransformer for building Knowledge Graphs has the same problem?

Thanks
