Issue Summary
I am trying to use ConversationSummaryMemory in LangChain, but the documentation link appears to be broken and the import path shown in tutorials does not work with the latest versions.
What I Tried
Using this import results in:
from langchain.memory import ConversationSummaryMemoryError:
Import "langchain.memory" could not be resolved
I also tried:
from langchain_community.memory import ConversationSummaryMemorybut I couldn't find any official documentation confirming this change.
Broken Documentation Link
When I search Google and follow links (example):
https://api.python.langchain.com/en/latest/langchain/memory/langchain.memory.summary.ConversationSummaryMemory.html
I get this browser error:
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
"This site can’t provide a secure connection"
