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)rr r r rrÚ!_InternalStreamlitCallbackHandlers úb/var/www/html/ai-engine/env/lib/python3.11/site-packages/langchain/callbacks/streamlit/__init__.pyrr sô€ðZ ØIÐIÐIÐIÐIÐIð(Ð'Ø Ø#9Ø 3Ø(CØ+ð  ñ ô ð øõ ð ð ð ð ð ð ð ð ð ð ð øõð ð ð ÝðNñôð ð øøøð 1Ð0Ø Ø#9Ø 3Ø(CØ+ð  ñ ô ð ð ð ð øøøs#‚˜ A£*©AªAÁAÁA) rrr rr rr rrrrr) Ú __future__rÚtypingrrÚlangchain_core.callbacks.baserÚlangchain_community.callbacksrÚstreamlit.delta_generatorrr©órúr"s«ðØ"Ð"Ð"Ð"Ð"Ð"à*Ð*Ð*Ð*Ð*Ð*Ð*Ð*à=Ð=Ð=Ð=Ð=Ð=àð9Ø?Ð?Ð?Ð?Ð?Ð?Ø8Ð8Ð8Ð8Ð8Ð8ð #$Ø $Ø(,Ø37ð I ðI ðI ðI ðI ðI ðI ðI r!
