- **Description:**
be able to use langchain with other version than tiktoken 0.3.3 i.e
0.5.1
- **Issue:**
cannot installed the conda-forge version since it applied all optional
dependency:
https://github.com/conda-forge/langchain-feedstock/pull/85
replace "^0.3.2" by "">=0.3.2,<0.6.0" and "^3.9" by python=">=3.9"
Tested with python 3.10, langchain=0.0.288 and tiktoken==0.5.0

## 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,
)
```

# Description
Adds logic for NotionDBLoader to correctly populate `last_edited_time`
and `created_time` fields from [page
properties](https://developers.notion.com/reference/page#property-value-object).
There are no relevant tests for this code to be updated.

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,
)
```
✅ `make format`, `make lint` and `make test`
## Description
Expanded the upper bound for `networkx` dependency to allow installation
of latest stable version. Tested the included sample notebook with
version 3.1, and all steps ran successfully.

Adds support for the `$vectorSearch` operator for
MongoDBAtlasVectorSearch, which was announced at .Local London
(September 26th, 2023). This change maintains breaks compatibility
support for the existing `$search` operator used by the original
integration (https://github.com/langchain-ai/langchain/pull/5338) due to
incompatibilities in the Atlas search implementations.

We noticed that as we have been moving developers to the new
`ElasticsearchStore` implementation, we want to keep the
ElasticVectorSearch class still available as developers transition
slowly to the new store.
To speed up this process, I updated the blurb giving them a better
recommendation of why they should use ElasticsearchStore.
