From 9031da842de6b5bef9d78b8cc24b2364b48fe367 Mon Sep 17 00:00:00 2001 From: ehsan Date: Fri, 11 Sep 2026 17:07:00 -0700 Subject: [PATCH] Migrate to langchain >=0.1.0,<0.3 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - **langchain.{vectorstores,document_loaders,utilities,tools,retrievers,chat_models,llms,embeddings,docstore,graphs,storage,agent_toolkits}.*** → `langchain_community.` (29 sites): Third-party integrations moved to langchain-community with identical module paths. - **langchain.chat_models.ChatOpenAI / langchain.llms.OpenAI / langchain.embeddings.OpenAIEmbeddings (+ Azure variants)** → `langchain_openai.{ChatOpenAI, OpenAI, OpenAIEmbeddings, AzureChatOpenAI, AzureOpenAI, AzureOpenAIEmbeddings}` (17 sites): OpenAI integrations moved to the langchain-openai partner package. - **langchain.text_splitter** → `langchain_text_splitters` (8 sites): Text splitters moved to their own package (0.2). Files touched: 30; files the mechanical pass matched but did not need to change: 7. Deterministic rewrites from a machine-readable MigrationSpec for this upgrade, then a review pass on the semantic residue; every changed file was parsed and checked with pyflakes for new undefined names before this PR was prepared. No behaviour beyond the migration was touched: no reformatting, no import reordering, no unrelated code. Happy to adjust anything — if the project deliberately pins the old major version, say so and I will close this. --- docs/langchain-retrieval-agent.ipynb | 2 +- docs/langchain-retrieval-augmentation.ipynb | 2 +- .../better-rag/02a-alt-chunking-methods.ipynb | 4 ++-- learn/generation/better-rag/xx-serverless-rag.ipynb | 6 +++--- learn/generation/chatbots/chatbot.ipynb | 6 +++--- .../conversational-agents/langchain-lex-agent.ipynb | 6 +++--- .../langchain/00-azure-openai-retrieval.ipynb | 6 +++--- .../generation/langchain/00b-azure-openai-simple.ipynb | 4 ++-- .../handbook/03-langchain-conversational-memory.ipynb | 2 +- .../langchain/handbook/03a-token-counter.ipynb | 2 +- .../handbook/05-langchain-retrieval-augmentation.ipynb | 2 +- .../langchain/handbook/06-langchain-agents.ipynb | 2 +- .../handbook/08-langchain-retrieval-agent.ipynb | 6 +++--- .../09-langchain-streaming.ipynb | 4 ++-- .../langchain/handbook/09-langchain-streaming/main.py | 4 ++-- .../langchain/handbook/10-langchain-multi-query.ipynb | 8 ++++---- .../handbook/11-langchain-expression-language.ipynb | 8 ++++---- .../langchain/handbook/xx-langchain-chunking.ipynb | 10 +++++----- .../langgraph/02-ollama-langgraph-agent/pyproject.toml | 5 ++++- .../llm-field-guide/falcon/falcon-40b-chatbot.ipynb | 4 ++-- .../gpt-j-6b/gpt-j-6b-huggingface-langchain.ipynb | 2 +- .../llama-2/llama-2-13b-retrievalqa.ipynb | 6 +++--- .../llama-2/llama-2-70b-chat-agent.ipynb | 4 ++-- .../llm-field-guide/mpt/mpt-30b-chatbot.ipynb | 2 +- .../mpt/mpt-7b-huggingface-langchain.ipynb | 2 +- .../open-llama/open-llama-huggingface-langchain.ipynb | 2 +- .../retrieval-augmentation-open-llama-langchain.ipynb | 6 +++--- .../openai/chatgpt/plugins/langchain-docs-plugin.ipynb | 4 ++-- .../gpt-3.5-agent-training/00-fine-tuning.ipynb | 2 +- learn/generation/openai/gpt-4-langchain-docs.ipynb | 2 +- .../rag-for-hybrid/rag-for-hybrid-search.ipynb | 4 ++-- .../structured-data/vectorizing-structured-data.ipynb | 2 +- learn/search/namespaces/namespaces_demo.ipynb | 6 +++--- pyproject.toml | 2 +- 34 files changed, 71 insertions(+), 68 deletions(-) diff --git a/docs/langchain-retrieval-agent.ipynb b/docs/langchain-retrieval-agent.ipynb index 17def8a6..29ac56db 100644 --- a/docs/langchain-retrieval-agent.ipynb +++ b/docs/langchain-retrieval-agent.ipynb @@ -70,7 +70,7 @@ "\n", " import requests\n", " from IPython.display import Image, display\n", -
