RuntimeError: There is no current event loop in thread 'ScriptRunner.scriptThread' after upgrade from langchain 0.0.202

Hi Team,

after upgrading langchain from 0.0.202, we are starting to get this error RuntimeError: There is no current event loop in thread 'ScriptRunner.scriptThread'.

Anybody seeing this or has figured out the work around or how to fix it?

To re-create the issue the code is as simple as this:

import streamlit as st
st.write("before import")
from langchain.chat_models import ChatOpenAI
st.write("after import")

Ended up resolving this by upgrading deeplake which was added in 0.0.203
pip3 install -U deeplake
