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. expand_new_thoughts Each LLM "thought" gets its own `st.expander`. This param controls whether that expander is expanded by default. collapse_completed_thoughts If `True`, LLM thought expanders will be collapsed when completed. thought_labeler An optional custom LLMThoughtLabeler instance. If unspecified, the handler will use the default thought labeling logic. 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)StreamlitCallbackHandlerr zoTo use the StreamlitCallbackHandler, please install langchain-community with `pip install langchain-community`.N)streamlit.external.langchainr ImportErrorBlangchain_community.callbacks.streamlit.streamlit_callback_handler) parent_containerr r r r r!_InternalStreamlitCallbackHandleremsgs l/var/www/auto_recruiter/arenv/lib/python3.12/site-packages/langchain_classic/callbacks/streamlit/__init__.pyrr sX I( #9 3(C+      *  *N c" )  *1 #9 3(C+    s, A&A A=AAA) rrr intr boolr rr zLLMThoughtLabeler | Nonereturnr) __future__rtypingrlangchain_core.callbacks.baserlangchain_community.callbacksrstreamlit.delta_generatorrrrr"sk" =?8 #$ $(,04 I $I  I  I "& I .
