Session factory is not initialized

[westonli-thu]

🐛 Describe the bug

I try to use App.from_config(config={...}), and I got this issue:

RuntimeError: Session factory is not initialized. Call setup_engine() first.

Is there any setting I missed? I run on local MacBook, and the version of embedchain is 0.1.83

Thanks for reporting @westonli-thu. I am looking into this issue now.

@westonli-thu can you please share the code that you are trying to use?

I tried to reproduce the issue on Google colab but it seems to be working fine. See Colab: https://colab.research.google.com/drive/1NMkAxTdHj-G4epFb9I6fMFX8tVPL7tn5?usp=sharing

Code below:

import os

os.environ['OPENAI_API_KEY'] = 'sk-xxx'

from embedchain import App


config = {
    'app': {
        "config": {
            "id": "ec-app"
        }
    }
}

app = App.from_config(config=config)

app.add("https://www.forbes.com/profile/elon-musk")

app.chat("What is the net worth of Elon Musk?")

from dotenv import load_dotenv

base_llm_config = BaseLlmConfig(prompt=prompt)
llm = OpenAILlm(config=base_llm_config)

ouput:
