Parameters ---------- parent_container The `st.container` that will contain all the Streamlit elements that the Handler creates. max_thought_containers The max number of completed LLM thought containers to show at once. When this threshold is reached, a new thought will cause the oldest thoughts to be collapsed into a "History" expander. Defaults to 4. expand_new_thoughts Each LLM "thought" gets its own `st.expander`. This param controls whether that expander is expanded by default. Defaults to True. collapse_completed_thoughts If True, LLM thought expanders will be collapsed when completed. Defaults to True. thought_labeler An optional custom LLMThoughtLabeler instance. If unspecified, the handler will use the default thought labeling logic. Defaults to None. Returns ------- A new StreamlitCallbackHandler instance. Note that this is an "auto-updating" API: if the installed version of Streamlit has a more recent StreamlitCallbackHandler implementation, an instance of that class will be used. r)ÚStreamlitCallbackHandlerr zoTo use the StreamlitCallbackHandler, please install langchain-community with `pip install langchain-community`.)Ústreamlit.external.langchainrÚ ImportErrorÚBlangchain_community.callbacks.streamlit.streamlit_callback_handler)Úparent_containerr r r rrÚ!_InternalStreamlitCallbackHandlers ú`/var/www/html/engine/venv/lib/python3.12/site-packages/langchain/callbacks/streamlit/__init__.pyrr s†€ðZ ÝIñ(Ø Ø#9Ø 3Ø(CØ+ô  ð øô ò ð ö øôò ÜðNóð ð úñ 1Ø Ø#9Ø 3Ø(CØ+ô  ò ð ús!‚• AŸ&¥A¦;»AÁ A) rrr Úintr Úboolr rrzOptional[LLMThoughtLabeler]Úreturnr) Ú __future__rÚtypingrrÚlangchain_core.callbacks.baserÚlangchain_community.callbacksrÚstreamlit.delta_generatorrr©órúr!skðÝ"ç*å=áÝ?Ý8ð #$Ø $Ø(,Ø37ñ I Ø$ðI ð ðI ðð I ð "&ð I ð 1ð I ðôI r
