# community: Fix AttributeError in RankLLMRerank (`list` object has no
attribute `candidates`)
## **Description**
This PR fixes an issue in `RankLLMRerank` where reranking fails with the
following error:
```
AttributeError: 'list' object has no attribute 'candidates'
```
The issue arises because `rerank_batch()` returns a `List[Result]`
instead of an object containing `.candidates`.
### **Changes Introduced**
- Adjusted `compress_documents()` to support both:
- Old API format: `rerank_results.candidates`
- New API format: `rerank_results` as a list
- Also fix wrong .txt location parsing while I was at it.
---
## **Issue**
Fixes **AttributeError** in `RankLLMRerank` when using
`compression_retriever.invoke()`. The issue is observed when
`rerank_batch()` returns a list instead of an object with `.candidates`.
**Relevant log:**
```
AttributeError: 'list' object has no attribute 'candidates'
```
## **Dependencies**
- No additional dependencies introduced.
---
## **Checklist**
- [x] **Backward compatible** with previous API versions
- [x] **Tested** locally with different RankLLM models
- [x] **No new dependencies introduced**
- [x] **Linted** with `make format && make lint`
- [x] **Ready for review**
---
## **Testing**
- Ran `compression_retriever.invoke(query)`
## **Reviewers**
If no review within a few days, please **@mention** one of:

The build in #29867 is currently broken because `langchain-cli` didn't
add download stats to the provider file.
This change gracefully handles sorting packages with missing download
counts. I initially updated the build to fetch download counts on every
run, but pypistats [requests](https://pypistats.org/api/) that users not
fetch stats like this via CI.

Fix the syntax for SQL-based metadata filtering in the [Google BigQuery
Vector Search
docs](https://python.langchain.com/docs/integrations/vectorstores/google_bigquery_vector_search/#searching-documents-with-metadata-filters).
Also add a link to learn more about BigQuery operators that can be used
here.
I have been using this library, and have found that this is the correct
syntax to use for the SQL-based filters.
**Issue**: no open issue.
**Dependencies**: none.
**Twitter handle**: none.
No tests as this is only a change to the documentation.

## **Description**
This PR updates the LangChain documentation to address an issue where
the `HuggingFaceEndpoint` example **does not specify the required `task`
argument**. Without this argument, users on `huggingface_hub == 0.28.1`
encounter the following error:
```
ValueError: Task unknown has no recommended model. Please specify a model explicitly.
```
---
## **Issue**
Fixes#29685
---
## **Changes Made**
✅ **Updated `HuggingFaceEndpoint` documentation** to explicitly define
`task="text-generation"`:
```python
llm = HuggingFaceEndpoint(
repo_id=GEN_MODEL_ID,
huggingfacehub_api_token=HF_TOKEN,
task="text-generation" # Explicitly specify task
)
```
✅ **Added a deprecation warning note** and recommended using
`InferenceClient`:
```python
from huggingface_hub import InferenceClient
from langchain.llms.huggingface_hub import HuggingFaceHub
client = InferenceClient(model=GEN_MODEL_ID, token=HF_TOKEN)
llm = HuggingFaceHub(
repo_id=GEN_MODEL_ID,
huggingfacehub_api_token=HF_TOKEN,
client=client,
)
```
---
## **Dependencies**
- No new dependencies introduced.
- Change only affects **documentation**.
---
## **Testing**
- ✅ Verified that adding `task="text-generation"` resolves the issue.
- ✅ Tested the alternative approach with `InferenceClient` in Google
Colab.

## Description
- Removed broken link for the API Reference
- Added `OPENAI_API_KEY` setter for the chains to properly run
- renamed one of our examples so it won't override the original
retriever and cause confusion due to it using a different mode of
retrieving
- Moved one of our simple examples to be the first example of our
retriever :)
**PR title**: "community: Option to pass auth_file_location for
oci_generative_ai"
**Description:** Option to pass auth_file_location, to overwrite config
file default location "~/.oci/config" where profile name configs
present. This is not fixing any issues. Just added optional parameter
called "auth_file_location", which internally supported by any OCI
client including GenerativeAiInferenceClient.

- **Description:** This PR introduces the `langchain-pull-md` package to
the LangChain community. It includes a new document loader that utilizes
the pull.md service to convert URLs into Markdown format, particularly
useful for handling web pages rendered with JavaScript frameworks like
React, Angular, or Vue.js. This loader helps in efficient and reliable
Markdown conversion directly from URLs without local rendering, reducing
server load.
- **Issue:** NA

Add a retriever to interact with Dappier APIs with an example notebook.
The retriever can be invoked with:
```python
from langchain_dappier import DappierRetriever
retriever = DappierRetriever(
data_model_id="dm_01jagy9nqaeer9hxx8z1sk1jx6",
k=5
)
retriever.invoke("latest tech news")
```
To retrieve 5 documents related to latest news in the tech sector. The
included notebook also includes deeper details about controlling filters
such as selecting a data model, number of documents to return, site
domain reference, minimum articles from the reference domain, and search
algorithm, as well as including the retriever in a chain.
The integration package can be found over here -
https://github.com/DappierAI/langchain-dappier
Problem:
"Optional" object is used in one example without importing, which raises
the following error when copying the example into IDE or Jupyter Lab
Solution:
Just importing Optional from typing_extensions module, this solves the
problem!

package, following LangChain's new guidelines for community
integrations.
**Notes:**

This pull request updates the documentation in
`docs/docs/how_to/custom_tools.ipynb` to reflect the recommended
approach for generating JSON schemas in Pydantic. Specifically, it
replaces instances of the deprecated `schema()` method with the newer
and more versatile `model_json_schema()`.
## Description
To integrate ModelScope inference API endpoints for both Embeddings,
LLMs and ChatModels, install the package
`langchain-modelscope-integration` (as discussed in issue #28928 ). This
is necessary because the package name `langchain-modelscope` was already
registered by another party.
ModelScope is a premier platform designed to connect model checkpoints
with model applications. It provides the necessary infrastructure to
share open models and promote model-centric development. For more
information, visit GitHub page:

- Title: Fix typo to correct "embedding" to "embeddings" in PGVector
initialization example
- Problem: There is a typo in the example code for initializing the
PGVector class. The current parameter "embedding" is incorrect as the
class expects "embeddings".
- Correction: The corrected code snippet is:
vector_store = PGVector(
embeddings=embeddings,
collection_name="my_docs",
connection="postgresql+psycopg://...",
)
Hi Erick. Coming back from a previous attempt, we now made a separate
package for the CrateDB adapter, called `langchain-cratedb`, as advised.
Other than registering the package within `libs/packages.yml`, this
patch includes a minimal amount of documentation to accompany the advent
of this new package. Let us know about any mistakes we made, or changes
you would like to see. Thanks, Andreas.
## About
- **Description:** Register a new database adapter package,
`langchain-cratedb`, providing traditional vector store, document
loader, and chat message history features for a start.
- **Addressed to:** @efriis, @eyurtsev
- **References:** GH-27710
- **Preview:** [Providers » More »
CrateDB](https://langchain-git-fork-crate-workbench-register-la-4bf945-langchain.vercel.app/docs/integrations/providers/cratedb/)
## Status
- **PyPI:** https://pypi.org/project/langchain-cratedb/
- **GitHub:** https://github.com/crate/langchain-cratedb
- **Documentation (CrateDB):**
https://cratedb.com/docs/guide/integrate/langchain/
- **Documentation (LangChain):** _This PR._
## Backlog?
Is this applicable for this kind of patch?
> - [ ] **Add tests and docs**: If you're adding a new integration,
please include
> 1. a test for the integration, preferably unit tests that do not rely
on network access,
> 2. an example notebook showing its use. It lives in
`docs/docs/integrations` directory.
## Q&A
1. Notebooks that use the LangChain CrateDB adapter are currently at
[CrateDB LangChain
Examples](https://github.com/crate/cratedb-examples/tree/main/topic/machine-learning/llm-langchain),
and the documentation refers to them. Because they are derived from very
old blueprints coming from LangChain 0.0.x times, we guess they need a
refresh before adding them to `docs/docs/integrations`. Is it applicable
to merge this minimal package registration + documentation patch, which
already includes valid code snippets in `cratedb.mdx`, and add
corresponding notebooks on behalf of a subsequent patch later?
2. How would it work getting into the tabular list of _Integration
Packages_ enumerated on the [documentation entrypoint page about
Providers](https://python.langchain.com/docs/integrations/providers/)?
/cc Please also review, @ckurze, @wierdvanderhaar, @kneth,

**Description:**
With current HTML splitters, they rely on secondary use of the
`RecursiveCharacterSplitter` to further chunk the document into
manageable chunks. The issue with this is it fails to maintain important
structures such as tables, lists, etc within HTML.
This Implementation of a HTML splitter, allows the user to define a
maximum chunk size, HTML elements to preserve in full, options to
preserve `<a>` href links in the output and custom handlers.
The core splitting begins with headers, similar to `HTMLHeaderSplitter`.
If these sections exceed the length of the `max_chunk_size` further
recursive splitting is triggered. During this splitting, elements listed
to preserve, will be excluded from the splitting process. This can cause
chunks to be slightly larger then the max size, depending on preserved
length. However, all contextual relevance of the preserved item remains
intact.
**Custom Handlers**: Sometimes, companies such as Atlassian have custom
HTML elements, that are not parsed by default with `BeautifulSoup`.
Custom handlers allows a user to provide a function to be ran whenever a
specific html tag is encountered. This allows the user to preserve and
gather information within custom html tags that `bs4` will potentially
miss during extraction.
**Dependencies:** User will need to install `bs4` in their project to
utilise this class
I have also added in `how_to` and unit tests, which require `bs4` to
run, otherwise they will be skipped.
Flowchart of process:

Issue: integrations related to a provider can be spread across several
packages and classes. It is very hard to find a provider using only
ToCs.
Fix: we have a very useful and helpful tool to search by provider name.
It is the `Search` field. So, I've added recommendations for using this
field. It seems obvious but it is not.

**Description:**
This PR addresses the `TypeError: sequence item 0: expected str
instance, FluentValue found` error when invoking `WikidataQueryRun`. The
root cause was an incompatible version of the
`wikibase-rest-api-client`, which caused the tool to fail when handling
`FluentValue` objects instead of strings.
The current implementation only supports `wikibase-rest-api-client<0.2`,
but the latest version is `0.2.1`, where the current implementation
breaks. Additionally, the error message advises users to install the
latest version: [code
reference](https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/utilities/wikidata.py#L125C25-L125C32).
Therefore, this PR updates the tool to support the latest version of
`wikibase-rest-api-client`.
Key changes:
- Updated the handling of `FluentValue` objects to ensure compatibility
with the latest `wikibase-rest-api-client`.
- Removed the restriction to `wikibase-rest-api-client<0.2` and updated
to support the latest version (`0.2.1`).
**Issue:**
Fixes [#24093](https://github.com/langchain-ai/langchain/issues/24093) –
`TypeError: sequence item 0: expected str instance, FluentValue found`.
**Dependencies:**
- Upgraded `wikibase-rest-api-client` to the latest version to resolve
the issue.

~Note that this PR is now Draft, so I didn't add change to `aindex`
function and didn't add test codes for my change.
After we have an agreement on the direction, I will add commits.~
`batch_size` is very difficult to decide because setting a large number
like >10000 will impact VectorDB and RecordManager, while setting a
small number will delete records unnecessarily, leading to redundant
work, as the `IMPORTANT` section says.
On the other hand, we can't use `full` because the loader returns just a
subset of the dataset in our use case.
I guess many people are in the same situation as us.
So, as one of the possible solutions for it, I would like to introduce a
new argument, `scoped_full_cleanup`.
This argument will be valid only when `claneup` is Full. If True, Full
cleanup deletes all documents that haven't been updated AND that are
associated with source ids that were seen during indexing. Default is
False.
This change keeps backward compatibility.

**Description:**
- **Memgraph** no longer relies on `Neo4jGraphStore` but **implements
`GraphStore`**, just like other graph databases.
- **Memgraph** no longer relies on `GraphQAChain`, but implements
`MemgraphQAChain`, just like other graph databases.
- The refresh schema procedure has been updated to try using `SHOW
SCHEMA INFO`. The fallback uses Cypher queries (a combination of schema
and Cypher) → **LangChain integration no longer relies on MAGE
library**.
- The **schema structure** has been reformatted. Regardless of the
procedures used to get schema, schema structure is the same.
- The `add_graph_documents()` method has been implemented. It transforms
`GraphDocument` into Cypher queries and creates a graph in Memgraph. It
implements the ability to use `baseEntityLabel` to improve speed
(`baseEntityLabel` has an index on the `id` property). It also
implements the ability to include sources by creating a `MENTIONS`
relationship to the source document.
- Jupyter Notebook for Memgraph has been updated.

## Description
First of all, thanks for the great framework that is LangChain!
At [Linkup](https://www.linkup.so/) we're working on an API to connect
LLMs and agents to the internet and our partner sources. We'd be super
excited to see our API integrated in LangChain! This essentially
consists in adding a LangChain retriever and tool, which is done in our
own [package](https://pypi.org/project/langchain-linkup/). Here we're
simply following the [integration
documentation](https://python.langchain.com/docs/contributing/how_to/integrations/)
and update the documentation of LangChain to mention the Linkup
integration.
We do have tests (both units & integration) in our [source
code](https://github.com/LinkupPlatform/langchain-linkup), and tried to
follow as close as possible the [integration
documentation](https://python.langchain.com/docs/contributing/how_to/integrations/)
which specifically requests to focus on documentation changes for an
integration PR, so I'm not adding tests here, even though the PR
checklist seems to suggest so. Feel free to correct me if I got this
wrong!
By the way, we would be thrilled by being mentioned in the list of
providers which have standalone packages
[here](https://langchain-git-fork-linkupplatform-cj-doc-langchain.vercel.app/docs/integrations/providers/),
is there something in particular for us to do for that? 🙂

Hi Langchain team!
I'm the co-founder and mantainer at
[ScrapeGraphAI](https://scrapegraphai.com/).
By following the integration
[guide](https://python.langchain.com/docs/contributing/how_to/integrations/publish/)
on your site, I have created a new lib called
[langchain-scrapegraph](https://github.com/ScrapeGraphAI/langchain-scrapegraph).
With this PR I would like to integrate Scrapegraph as provider in
Langchain, adding the required documentation files.
Let me know if there are some changes to be made to be properly
integrated both in the lib and in the documentation.
Thank you 🕷️🦜

This PR updates the Pinecone client to `5.4.0`, as well as its
dependencies (`pinecone-plugin-inference` and
`pinecone-plugin-interface`).
Note: `pinecone-client` is now simply called `pinecone`.
**Question for reviewer(s):** should this PR also update the `pinecone`
dep in [the root dir's `poetry.lock`
file](https://github.com/langchain-ai/langchain/blob/master/poetry.lock#L6729)?
Was unsure. (I don't believe so b/c it seems pinned to a lower version
likely based on 3rd-party deps (e.g. Unstructured).)

In collaboration with @rlouf I build an
[outlines](https://dottxt-ai.github.io/outlines/latest/) integration for
langchain!
I think this is really useful for doing any type of structured output
locally.
[Dottxt](https://dottxt.co) spend alot of work optimising this process
at a lower level
([outlines-core](https://pypi.org/project/outlines-core/0.1.14/) written
in rust) so I think this is a better alternative over all current
approaches in langchain to do structured output.
It also implements the `.with_structured_output` method so it should be
a drop in replacement for a lot of applications.
The integration includes:
- **Outlines LLM class**
- **ChatOutlines class**
- **Tutorial Cookbooks**
- **Documentation Page**
- **Validation and error messages**
- **Exposes Outlines Structured output features**
- **Support for multiple backends**
- **Integration and Unit Tests**
Dependencies: `outlines` + additional (depending on backend used)
I am not sure if the unit-tests comply with all requirements, if not I
suggest to just remove them since I don't see a useful way to do it
differently.

When `ToolNode` hyperlink is clicked, it does not automatically scroll
to the section due to incorrect reference to the heading / id in the
LangGraph documentation
Think it's worth adding a quick guide and including in the table in the
concepts page. `StrOutputParser` can make it easier to deal with the
union type for message content. For example, ChatAnthropic with bound
tools will generate string content if there are no tool calls and
`list[dict]` content otherwise.
I'm also considering removing the output parser section from the
["quickstart"
tutorial](https://python.langchain.com/docs/tutorials/llm_chain/); we
can link to this guide instead.
For me, the [Pydantic
example](https://python.langchain.com/docs/how_to/structured_output/#choosing-between-multiple-schemas)
does not work (tested on various Python versions from 3.10 to 3.12, and
`Pydantic` versions from 2.7 to 2.9).
The `TypedDict` example (added in this PR) does.
----
Additionally, fixed an error in [Using PydanticOutputParser
example](https://python.langchain.com/docs/how_to/structured_output/#using-pydanticoutputparser).
Was:
```python
query = "Anna is 23 years old and she is 6 feet tall"
print(prompt.invoke(query).to_string())
```
Corrected to:
```python
query = "Anna is 23 years old and she is 6 feet tall"
print(prompt.invoke({"query": query}).to_string())

**Description:**
This PR modifies the documentation regarding the configuration of the
VLLM with the LoRA adapter. The updates aim to provide clear
instructions for users on how to set up the LoRA adapter when using the
VLLM.
- before
```python
VLLM(..., enable_lora=True)
```
- after
```python
VLLM(...,
vllm_kwargs={
"enable_lora": True
}
)
```
This change clarifies that users should use the vllm_kwargs to enable
the LoRA adapter.

# OCR-based PDF loader
This implements [Zerox](https://github.com/getomni-ai/zerox) PDF
document loader.
Zerox utilizes simple but very powerful (even though slower and more
costly) approach to parsing PDF documents: it converts PDF to series of
images and passes it to a vision model requesting the contents in
markdown.
It is especially suitable for complex PDFs that are not parsed well by
other alternatives.
## Example use:
```python
from langchain_community.document_loaders.pdf import ZeroxPDFLoader
os.environ["OPENAI_API_KEY"] = "" ## your-api-key
model = "gpt-4o-mini" ## openai model
pdf_url = "https://assets.ctfassets.net/f1df9zr7wr1a/soP1fjvG1Wu66HJhu3FBS/034d6ca48edb119ae77dec5ce01a8612/OpenAI_Sacra_Teardown.pdf"
loader = ZeroxPDFLoader(file_path=pdf_url, model=model)
docs = loader.load()
```
The Zerox library supports wide range of provides/models. See Zerox
documentation for details.

## Description
This PR adds support for Memcached as a usable LLM model cache by adding
the ```MemcachedCache``` implementation relying on the
[pymemcache](https://github.com/pinterest/pymemcache) client.
Unit test-wise, the new integration is generally covered under existing
import testing. All new functionality depends on pymemcache if
instantiated and used, so to comply with the other cache implementations
the PR also adds optional integration tests for ```MemcachedCache```.
Since this is a new integration, documentation is added for Memcached as
an integration and as an LLM Cache.
## Issue
This PR closes#27275 which was originally raised as a discussion in
#27035
## Dependencies
There are no new required dependencies for langchain, but
[pymemcache](https://github.com/pinterest/pymemcache) is required to
instantiate the new ```MemcachedCache```.
## Example Usage
```python3
from langchain.globals import set_llm_cache
from langchain_openai import OpenAI
from langchain_community.cache import MemcachedCache
from pymemcache.client.base import Client
llm = OpenAI(model="gpt-3.5-turbo-instruct", n=2, best_of=2)
set_llm_cache(MemcachedCache(Client('localhost')))
# The first time, it is not yet in cache, so it should take longer
llm.invoke("Which city is the most crowded city in the USA?")
# The second time it is, so it goes faster
llm.invoke("Which city is the most crowded city in the USA?")

## What this PR does?
### Currently `O365BaseLoader` (and consequently both derived loaders)
are limited to `pdf`, `doc`, `docx` files.
- **Solution: here we introduce _handlers_ attribute that allows for
custom handlers to be passed in. This is done in _dict_ form:**
**Example:**
```python
from langchain_community.document_loaders.parsers.documentloader_adapter import DocumentLoaderAsParser
# PR for DocumentLoaderAsParser here: https://github.com/langchain-ai/langchain/pull/27749
from langchain_community.document_loaders.excel import UnstructuredExcelLoader
xlsx_parser = DocumentLoaderAsParser(UnstructuredExcelLoader, mode="paged")
# create dictionary mapping file types to handlers (parsers)
handlers = {
"doc": MsWordParser()
"pdf": PDFMinerParser()
"txt": TextParser()
"xlsx": xlsx_parser
}
loader = SharePointLoader(document_library_id="...",
handlers=handlers # pass handlers to SharePointLoader
)
documents = loader.load()
# works the same in OneDriveLoader
loader = OneDriveLoader(document_library_id="...",
handlers=handlers
)
```
This dictionary is then passed to `MimeTypeBasedParser` same as in the
[current
implementation](5a2cfb49e0/libs/community/langchain_community/document_loaders/parsers/registry.py (L13)).
### Currently `SharePointLoader` and `OneDriveLoader` are separate
loaders that both inherit from `O365BaseLoader`
However both of these implement the same functionality. The only
differences are:
- `SharePointLoader` requires argument `document_library_id` whereas
`OneDriveLoader` requires `drive_id`. These are just different names for
the same thing.
- `SharePointLoader` implements significantly more features.
- **Solution: `OneDriveLoader` is replaced with an empty shell just
renaming `drive_id` to `document_library_id` and inheriting from
`SharePointLoader`**
**Dependencies:** None

### Description/Issue:
I had problems filtering when setting up a local Milvus db and noticed
that the `filter` option in the `similarity_search` and
`similarity_search_with_score` appeared to do nothing. Instead, the
`expr` option should be used.
The `expr` option is correctly used in the retriever example further
down in the documentation.
The `expr` option seems to be correctly passed on, for example
[here](447c0dd2f0/libs/community/langchain_community/vectorstores/milvus.py (L701))
### Solution:
Update the documentation for the functions mentioned to show intended
