- **Description:** A Document Loader for MongoDB
- **Issue:** n/a
- **Dependencies:** Motor, the async driver for MongoDB
- **Tag maintainer:** n/a
- **Twitter handle:** pigpenblue
Note that an initial mongodb document loader was created 4 months ago,
but the [PR ](https://github.com/langchain-ai/langchain/pull/4285)was
never pulled in. @leo-gan had commented on that PR, but given it is
extremely far behind the master branch and a ton has changed in
Langchain since then (including repo name and structure), I rewrote the
branch and issued a new PR with the expectation that the old one can be
closed.
Please reference that old PR for comments/context, but it can be closed
in favor of this one. Thanks!

## Description
As of now, when instantiating and during inference, `LlamaCppEmbeddings`
outputs (a lot of) verbose when controlled from Langchain binding - it
is a bit annoying when computing the embeddings of long documents, for
instance.
This PR adds `verbose` for `LlamaCppEmbeddings` objects to be able
**not** to print the verbose of the model to `stderr`. It is natively
supported by `llama-cpp-python` and directly passed to the library – the
PR is hence very small.
The value of `verbose` is `True` by default, following the way it is
defined in [`LlamaCpp` (`llamacpp.py`
#L136-L137)](c87e9fb2ce/libs/langchain/langchain/llms/llamacpp.py (L136-L137))
## Issue
_No issue linked_
## Dependencies
_No additional dependency needed_
## To see it in action
```python
from langchain.embeddings import LlamaCppEmbeddings
MODEL_PATH = "<path_to_gguf_file>"
if __name__ == "__main__":
llm_embeddings = LlamaCppEmbeddings(
model_path=MODEL_PATH,
n_gpu_layers=1,
n_batch=512,
n_ctx=2048,
f16_kv=True,
verbose=False,

Based on the customers' requests for native langchain integration,
SearchApi is ready to invest in AI and LLM space, especially in
open-source development.
- This is our initial PR and later we want to improve it based on
customers' and langchain users' feedback. Most likely changes will
affect how the final results string is being built.
- We are creating similar native integration in Python and JavaScript.
- The next plan is to integrate into Java, Ruby, Go, and others.
- Feel free to assign @SebastjanPrachovskij as a main reviewer for any
SearchApi-related searches. We will be glad to help and support
langchain development.
- **Description:**
- Make running integration test for opensearch easy
- Provide a way to use different text for embedding: refer to #11002 for
more of the use case and design decision.
- **Issue:** N/A
- **Dependencies:** None other than the existing ones.
Both black and mypy expect a list of files or directories as input.
As-is the Makefile computes a list files changed relative to the last
commit; these are passed to black and mypy in the `format_diff` and
`lint_diff` targets. This is done by way of the Makefile variable
`PYTHON_FILES`. This is to save time by skipping running mypy and black
over the whole source tree.
When no changes have been made, this variable is empty, so the call to
black (and mypy) lacks input files. The call exits with error causing
the Makefile target to error out with:
```bash
$ make format_diff
poetry run black
Usage: black [OPTIONS] SRC ...
One of 'SRC' or 'code' is required.
make: *** [format_diff] Error 1
```
This is unexpected and undesirable, as the naive caller (that's me! 😄 )
will think something else is wrong. This commit smooths over this by
short circuiting when `PYTHON_FILES` is empty.
- **Description:** The types of 'destination_chains' and 'default_chain'
in 'MultiPromptChain' were changed from 'LLMChain' to 'Chain'. and
removed variables declared overlapping with the parent class
- **Issue:** When a class that inherits only Chain and not LLMChain,
such as 'SequentialChain' or 'RetrievalQA', is entered in
'destination_chains' and 'default_chain', a pydantic validation error is
raised.
- - codes
```
retrieval_chain = ConversationalRetrievalChain(
retriever=doc_retriever,
combine_docs_chain=combine_docs_chain,
question_generator=question_gen_chain,
)
destination_chains = {
'retrieval': retrieval_chain,
}
main_chain = MultiPromptChain(
router_chain=router_chain,
destination_chains=destination_chains,
default_chain=default_chain,
verbose=True,
)
```

My PR is passing linting and testing before submitting.
This adds `input_schema` and `output_schema` properties to all
runnables, which are Pydantic models for the input and output types
respectively. These are inferred from the structure of the Runnable as
much as possible, the only manual typing needed is
- optionally add type hints to lambdas (which get translated to
input/output schemas)
- optionally add type hint to RunnablePassthrough
These schemas can then be used to create JSON Schema descriptions of
input and output types, see the tests
- [x] Ensure no InputType and OutputType in our classes use abstract
base classes (replace with union of subclasses)
- [x] Implement in BaseChain and LLMChain
- [x] Implement in RunnableBranch
- [x] Implement in RunnableBinding, RunnableMap, RunnablePassthrough,
RunnableEach, RunnableRouter
- [x] Implement in LLM, Prompt, Chat Model, Output Parser, Retriever
- [x] Implement in RunnableLambda from function signature

Adds LangServe package
* Integrate Runnables with Fast API creating Server and a RemoteRunnable
client
* Support multiple runnables for a given server
* Support sync/async/batch/abatch/stream/astream/astream_log on the
client side (using async implementations on server)
* Adds validation using annotations (relying on pydantic under the hood)
-- this still has some rough edges -- e.g., open api docs do NOT
generate correctly at the moment
* Uses pydantic v1 namespace
Known issues: type translation code doesn't handle a lot of types (e.g.,
TypedDicts)

- **Description:** Prompt wrapping requirements have been implemented on
the service side of AWS Bedrock for the Anthropic Claude models to
provide parity between Anthropic's offering and Bedrock's offering. This
overnight change broke most existing implementations of Claude, Bedrock
and Langchain. This PR just steals the the Anthropic LLM implementation
to enforce alias/role wrapping and implements it in the existing
mechanism for building the request body. This has also been tested to
fix the chat_model implementation as well. Happy to answer any further
questions or make changes where necessary to get things patched and up
to PyPi ASAP, TY.

this is actually an oversight - this merges all dfs into one df. we DO
NOT want to do this - the idea is we work and manipulate multiple dfs
This removes the use of the intermediate df list and directly
concatenates the dataframes if path is a list of strings. The pd.concat
function combines the dataframes efficiently, making it faster and more
memory-efficient compared to appending dataframes to a list.

This is not correct. We should be able to expect that the vectorsotre
now includes doc1_1, doc1_2, and doc2, but not doc1_1, doc1_2, and
doc1_2.
# Reason
In `index`, the original code is
```python
uids = []
docs_to_index = []
for doc, hashed_doc, doc_exists in zip(doc_batch, hashed_docs, exists_batch):
if doc_exists:
# Must be updated to refresh timestamp.
record_manager.update([hashed_doc.uid], time_at_least=index_start_dt)
num_skipped += 1
continue
uids.append(hashed_doc.uid)
docs_to_index.append(doc)
```
In the aforementioned example, `len(doc_batch) == 4`, but
`len(hashed_docs) == len(exists_batch) == 3`. This is because the
deduplication of input documents [doc1_1, doc1_2, doc1_2, doc2] is
[doc1_1, doc1_2, doc2]. So `index` insert doc1_1, doc1_2, doc1_2 with
the uid of doc1_1, doc1_2, doc2.

This PR makes `ChatAnthropic.anthropic_api_key` a `pydantic.SecretStr`
to avoid inadvertently exposing API keys when the `ChatAnthropic` object
is represented as a str.
**Description**
Fixes broken link to `CONTRIBUTING.md` in `libs/langchain/README.md`.
Because`libs/langchain/README.md` was copied from the top level README,
and because the README contains a link to `.github/CONTRIBUTING.md`, the
copied README's link relative path must be updated. This commit fixes
that link.

### Description
- Add support for streaming with `Bedrock` LLM and `BedrockChat` Chat
Model.
- Bedrock as of now supports streaming for the `anthropic.claude-*` and
`amazon.titan-*` models only, hence support for those have been built.
- Also increased the default `max_token_to_sample` for Bedrock
`anthropic` model provider to `256` from `50` to keep in line with the
`Anthropic` defaults.
- Added examples for streaming responses to the bedrock example
notebooks.
**_NOTE:_**: This PR fixes the issues mentioned in #9897 and makes that
PR redundant.
- **Description:** QianfanEndpoint bugs for SystemMessages. When the

This PR addresses the limitation of Azure OpenAI embeddings, which can
handle at maximum 16 texts in a batch. This can be solved setting
`chunk_size=16`. However, I'd love to have this automated, not to force
the user to figure where the issue comes from and how to solve it.
Closes#4575.

**Description:** This PR adds HTTP PUT support for the langchain openapi
agent toolkit by leveraging existing structure and HTTP put request
wrapper. The PUT method is almost identical to HTTP POST but should be
idempotent and therefore tighter than POST which is not idempotent. Some
APIs may consider to use PUT instead of POST which is unfortunately not
supported with the current toolkit yet.

print(output)
# {'fields': {'colors': ['blue', 'yellow']},
'preferences': {'style': 'Make it in a style of a weather forecast.'},
'text': "Good morning! Today's weather forecast brings a beautiful combination of colors to the sky, with hues of blue and yellow gently blending together like a mesmerizing painting."}

**Issue:** I need to use the latest version of that dependency in my

to the lockfiles as it was the first time it was with the

## Description
This PR updates the `NeptuneGraph` class to start using the boto API for
connecting to the Neptune service. With boto integration, the graph
class now supports authenticating requests using Sigv4; this is
encapsulated with the boto API, and users only have to ensure they have
the correct AWS credentials setup in their workspace to work with the
graph class.
This PR also introduces a conditional prompt that uses a simpler prompt
when using the `Anthropic` model provider. A simpler prompt have seemed
to work better for generating cypher queries in our testing.
**Note**: This version will require boto3 version 1.28.38 or greater to
work.
**Description:**
This commit enriches the `WeaviateHybridSearchRetriever` class by
introducing a new parameter, `hybrid_search_kwargs`, within the
`_get_relevant_documents` method. This parameter accommodates arbitrary
keyword arguments (`**kwargs`) which can be channeled to the inherited
public method, `get_relevant_documents`, originating from the
`BaseRetriever` class.
This modification facilitates more intricate querying capabilities,
allowing users to convey supplementary arguments to the `.with_hybrid()`
method. This expansion not only makes it possible to perform a more
nuanced search targeting specific properties but also grants the ability
to boost the weight of searched properties, to carry out a search with a
custom vector, and to apply the Fusion ranking method. The documentation
has been updated accordingly to delineate these new possibilities in
detail.
In light of the layered approach in which this search operates,
initiating with `query.get()` and then transitioning to
`.with_hybrid()`, several advantageous opportunities are unlocked for
the hybrid component that were previously unattainable.
Here’s a representative example showcasing a query structure that was
formerly unfeasible:
[Specific Properties
Only](https://weaviate.io/developers/weaviate/search/hybrid#selected-properties-only)
"The example below illustrates a BM25 search targeting the keyword
'food' exclusively within the 'question' property, integrated with
vector search results corresponding to 'food'."
```python
response = (
client.query
.get("JeopardyQuestion", ["question", "answer"])
.with_hybrid(
query="food",
properties=["question"], # Will now be possible moving forward
alpha=0.25
)
.with_limit(3)
.do()
)
```
This functionality is now accessible through my alterations, by
conveying `hybrid_search_kwargs={"properties": ["question", "answer"]}`
as an argument to
`WeaviateHybridSearchRetriever.get_relevant_documents()`. For example:
```python
import os
from weaviate import Client
from langchain.retrievers import WeaviateHybridSearchRetriever
client = Client(
url=os.getenv("WEAVIATE_CLIENT_URL"),
additional_headers={
"X-OpenAI-Api-Key": os.getenv("OPENAI_API_KEY"),
"Authorization": f"Bearer {os.getenv('WEAVIATE_API_KEY')}",
},
)
index_name = "Document"
text_key = "content"
attributes = ["title", "summary", "header", "url"]
retriever = ExtendedWeaviateHybridSearchRetriever(
client=client,
index_name=index_name,
text_key=text_key,
attributes=attributes,
)
# Warning: to utilize properties in this way, each use property must also be in the list `attributes + [text_key]`.
hybrid_search_kwargs = {"properties": ["summary^2", "content"]}
query_text = "Some Query Text"
relevant_docs = retriever.get_relevant_documents(
query=query_text,
hybrid_search_kwargs=hybrid_search_kwargs
)
```
In my experience working with the `weaviate-client` library, I have
found that these supplementary options stand as vital tools for
refining/finetuning searches, notably within multifaceted datasets. As a
final note, this implementation supports both backwards and forward
(within reason) compatiblity. It accommodates any future additional
parameters Weaviate may add to `.with_hybrid()`, without necessitating
further alterations.

auto-encoding introduced in

"MacRoman" instead of the (correct) "UTF-8".
To address this, I've added the ability to disable the auto-encoding, as

process. This allows users to include custom configurations when
utilizing LangChain features like LLMChain.
- It also fixes some format issues for the docstrings.
Hello @hwchase17
**Issue**:
The class WebResearchRetriever accept only
RecursiveCharacterTextSplitter, but never uses a specification of this

- tools invoked in async methods would not work due to missing await
- RunnableSequence.stream() was creating an extra root run by mistake,
and it can simplified due to existence of default implementation for
.transform()

Hello,
this PR improves coverage for caching by the two Cassandra-related
caches (i.e. exact-match and semantic alike) by switching to the more
general `dumps`/`loads` serdes utilities.
This enables cache usage within e.g. `ChatOpenAI` contexts (which need
to store lists of `ChatGeneration` instead of `Generation`s), which was
not possible as long as the cache classes were relying on the legacy
`_dump_generations_to_json` and `_load_generations_from_json`).
Additionally, a slightly different init signature is introduced for the
cache objects:
- named parameters required for init, to pave the way for easier changes
in the future connect-to-db flow (and tests adjusted accordingly)
- added a `skip_provisioning` optional passthrough parameter for use
cases where the user knows the underlying DB table, etc already exist.
Thank you for a review!
Adding support for Neo4j vector index hybrid search option. In Neo4j,
you can achieve hybrid search by using a combination of vector and
fulltext indexes.

`langchain.agents.openai_functions[_multi]_agent._parse_ai_message()`
incorrectly extracts AI message content, thus LLM response ("thoughts")
is lost and can't be logged or processed by callbacks.

This PR addresses a few minor issues with the Cassandra vector store
implementation and extends the store to support Metadata search.
Thanks to the latest cassIO library (>=0.1.0), metadata filtering is
available in the store.
Further,
- the "relevance" score is prevented from being flipped in the [0,1]
interval, thus ensuring that 1 corresponds to the closest vector (this
is related to how the underlying cassIO class returns the cosine
difference);
- bumped the cassIO package version both in the notebooks and the
pyproject.toml;
- adjusted the textfile location for the vector-store example after the
reshuffling of the Langchain repo dir structure;
- added demonstration of metadata filtering in the Cassandra vector
store notebook;
- better docstring for the Cassandra vector store class;
- fixed test flakiness and removed offending out-of-place escape chars
from a test module docstring;
To my knowledge all relevant tests pass and mypy+black+ruff don't
complain. (mypy gives unrelated errors in other modules, which clearly
don't depend on the content of this PR).
Thank you!
Stefano
