Description

Currently, some test cases in integration module, like test_ollama_chat_model and test_ollama_embedding_model require start ollama server and pull model. To decrease CI cost, currently we only run these in CI with python 3.9 & linux environment, which may be confused for developer when only this version CI failed.

We should split integration test with other module test.
