These need to be set to equal for embedding models. * The embedding.cpp example has an assertion to make sure these are always equal. * Apparently this is not being done properly in llama-cpp-python. With `n_batch` set to 8, if more than 8 tokens are passed the batch runs out of space and it crashes. This also explains why the CPU compute buffer size was small: raw client with default `n_batch=512` ``` llama_new_context_with_model: CPU input buffer size = 3.51 MiB llama_new_context_with_model: CPU compute buffer size = 21.00 MiB ``` langchain with `n_batch=8` ``` llama_new_context_with_model: CPU input buffer size = 0.04 MiB llama_new_context_with_model: CPU compute buffer size = 0.33 MiB ``` We can work around this by passing `n_batch=512`, but this will not be obvious to some users: ``` embedding = LlamaCppEmbeddings(model_path=embd_model_path, n_batch=512) ``` From discussion w/ @cebtenzzre.

This is in part due to a small bug in pyright (https://github.com/microsoft/pyright/issues/7448 ) - however, the `Type` bound in the typevar `C = TypeVar("C", Type, Callable)` is not doing anything - classes are `Callables` by default, so by my understanding binding to `Type` does not actually provide any more safety - the modified annotation still works correctly for both functions, properties, and classes. --------- Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	5 months ago

Davide Menini	f7042321f1	community[patch]: gather token usage info in BedrockChat during generation (#19127 ) This PR allows to calculate token usage for prompts and completion directly in the generation method of BedrockChat. The token usage details are then returned together with the generations, so that other downstream tasks can access them easily. This allows to define a callback for tokens tracking and cost calculation, similarly to what happens with OpenAI (see [OpenAICallbackHandler](https://api.python.langchain.com/en/latest/_modules/langchain_community/callbacks/openai_info.html#OpenAICallbackHandler). I plan on adding a BedrockCallbackHandler later. Right now keeping track of tokens in the callback is already possible, but it requires passing the llm, as done here: https://how.wtf/how-to-count-amazon-bedrock-anthropic-tokens-with-langchain.html. However, I find the approach of this PR cleaner. Thanks for your reviews.

Also, changed to use map() which is more than twice as fast compared to the current implementation. ``` import timeit # Sample retriever_docs with varying lengths of sublists retriever_docs = [[i for i in range(j)] for j in range(1, 1000)] # First code snippet code1 = ''' max_docs = max(len(docs) for docs in retriever_docs) ''' # Second code snippet code2 = ''' max_docs = max(map(len, retriever_docs), default=0) ''' # Benchmarking time1 = timeit.timeit(stmt=code1, globals=globals(), number=10000) time2 = timeit.timeit(stmt=code2, globals=globals(), number=10000) # Output print(f"Execution time for code snippet 1: {time1} seconds") print(f"Execution time for code snippet 2: {time2} seconds") ``` - Dependencies: none	5 months ago

Christian Galo	1adaa3c662	community[minor]: Update Azure Cognitive Services to Azure AI Services (#19488 ) This is a follow up to #18371. These are the changes: - New Azure AI Services toolkit and tools to replace those of Azure Cognitive Services. - Updated documentation for Microsoft platform. - The image analysis tool has been rewritten to use the new package `azure-ai-vision-imageanalysis`, doing a proper replacement of `azure-ai-vision`. These changes: - Update outdated naming from "Azure Cognitive Services" to "Azure AI Services". - Update documentation to use non-deprecated methods to create and use agents. - Removes need to depend on yanked python package (`azure-ai-vision`) There is one new dependency that is needed as a replacement to `azure-ai-vision`: - `azure-ai-vision-imageanalysis`. This is optional and declared within a function. There is a new `azure_ai_services.ipynb` notebook showing usage; Changes have been linted and formatted.

Nuno Campos	fdfb51ad8d	core: Two updates to chat model interface (#19684 ) - .stream() and .astream() call on_llm_new_token, removing the need for subclasses to do so. Backwards compatible because now we don't pass run_manager into ._stream and ._astream - .generate() and .agenerate() now handle `stream: bool` kwarg for _generate and _agenerate. Subclasses handle this arg by delegating to ._stream(), now one less thing they need to do. Backwards compat because this is an optional arg that we now never pass to the subclasses - .generate() and .agenerate() now inspect callback handlers to decide on a default value for stream:bool if not passed in. This auto enables streaming when using astream_events and astream_log - as a result of these three changes any usage of .astream_events and .astream_log should now yield chat model stream events - In future PRs we can update all subclasses to reflect these two things now handled by base class, but in meantime all will continue to work	5 months ago

mwmajewsk	f7a1fd91b8	community: better support of pathlib paths in document loaders (#18396 ) So this arose from the https://github.com/langchain-ai/langchain/pull/18397 problem of document loaders not supporting `pathlib.Path`. This pull request provides more uniform support for Path as an argument. The core ideas for this upgrade: - if there is a local file path used as an argument, it should be supported as `pathlib.Path` - if there are some external calls that may or may not support Pathlib, the argument is immidiately converted to `str` - if there `self.file_path` is used in a way that it allows for it to stay pathlib without conversion, is is only converted for the metadata.

Yuki Watanabe	cfecbda48b	community[minor]: Allow passing `allow_dangerous_deserialization` when loading LLM chain (#18894 ) ### Issue Recently, the new `allow_dangerous_deserialization` flag was introduced for preventing unsafe model deserialization that relies on pickle without user's notice (#18696). Since then some LLMs like Databricks requires passing in this flag with true to instantiate the model. However, this breaks existing functionality to loading such LLMs within a chain using `load_chain` method, because the underlying loader function [load_llm_from_config](`f96dd57501/libs/langchain/langchain/chains/loading.py (L40)`) (and load_llm) ignores keyword arguments passed in. ### Solution This PR fixes this issue by propagating the `allow_dangerous_deserialization` argument to the class loader iff the LLM class has that field. --------- Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com> Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com>	5 months ago

Shotaro Sano	55c624a694	infra: Resolve the endless dependency resolution during the build of `dev.Dockerfile` by copying `poetry.lock` (#19465 ) ## Description This PR proposes a modification to the `libs/langchain/dev.Dockerfile` configuration to copy the `libs/langchain/poetry.lock` into the working directory. The change aims to address the issue where the Poetry install command, the last command in the `dev.Dockerfile`, takes excessively long hours, and to ensure the reproducibility of the poetry environment in the devcontainer. ## Problem The `dev.Dockerfile`, prepared for development environments such as `.devcontainer`, encounters an unending dependency resolution when attempting the Poetry installation. ### Steps to Reproduce Execute the following build command: ```bash docker build -f libs/langchain/dev.Dockerfile . ``` ### Current Behavior The Docker build process gets stuck at the following step, which, in my experience, did not conclude even after an entire night: ``` => [langchain-dev-dependencies 4/6] COPY libs/community/ ../community/ 0.9s => [langchain-dev-dependencies 5/6] COPY libs/text-splitters/ ../text-splitters/ 0.0s => [langchain-dev-dependencies 6/6] RUN poetry install --no-interaction --no-ansi --with dev,test,docs 12.3s => => # Updating dependencies => => # Resolving dependencies... ``` ### Expected Behavior The Docker build completes in a realistic timeframe. By applying this PR, the build finishes within a few minutes. ### Analysis The complexity of LangChain's dependencies has reached a point where Poetry is required to resolve dependencies akin to threading a needle. Consequently, poetry install fails to complete in a practical timeframe. ## Solution The solution for dependency resolution is already recorded in `libs/langchain/poetry.lock`, so we can use it. When copying `project.toml` and `poetry.toml`, the `poetry.lock` located in the same directory should also be copied. ```diff # Copy only the dependency files for installation -COPY libs/langchain/pyproject.toml libs/langchain/poetry.toml ./ +COPY libs/langchain/pyproject.toml libs/langchain/poetry.toml libs/langchain/poetry.lock ./ ``` ## Note I am not intimately familiar with the historical context of the `dev.Dockerfile` and thus do not know why `poetry.lock` has not been copied until now. It might have been an oversight, or perhaps dependency resolution used to complete quickly even without the `poetry.lock` file in the past. However, if there are deliberate reasons why copying `poetry.lock` is not advisable, please just close this PR.	5 months ago

Clément Tamines	a6cbb755a7	community[patch]: fix semantic answer bug in AzureSearch vector store (#18938 ) - Description: The `semantic_hybrid_search_with_score_and_rerank` method of `AzureSearch` contains a hardcoded field name "metadata" for the document metadata in the Azure AI Search Index. Adding such a field is optional when creating an Azure AI Search Index, as other snippets from `AzureSearch` test for the existence of this field before trying to access it. Furthermore, the metadata field name shouldn't be hardcoded as "metadata" and use the `FIELDS_METADATA` variable that defines this field name instead. In the current implementation, any index without a metadata field named "metadata" will yield an error if a semantic answer is returned by the search in `semantic_hybrid_search_with_score_and_rerank`. - Issue: https://github.com/langchain-ai/langchain/issues/18731 - Prior fix to this bug: This bug was fixed in this PR https://github.com/langchain-ai/langchain/pull/15642 by adding a check for the existence of the metadata field named `FIELDS_METADATA` and retrieving a value for the key called "key" in that metadata if it exists. If the field named `FIELDS_METADATA` was not present, an empty string was returned. This fix was removed in this PR https://github.com/langchain-ai/langchain/pull/15659 (see `ed1ffca911`#). @lz-chen: could you confirm this wasn't intentional? - New fix to this bug: I believe there was an oversight in the logic of the fix from [#1564](https://github.com/langchain-ai/langchain/pull/15642) which I explain below. The `semantic_hybrid_search_with_score_and_rerank` method creates a dictionary `semantic_answers_dict` with semantic answers returned by the search as follows. `5c2f7e6b2b/libs/community/langchain_community/vectorstores/azuresearch.py (L574-L581)` The keys in this dictionary are the unique document ids in the index, if I understand the [documentation of semantic answers](https://learn.microsoft.com/en-us/azure/search/semantic-answers) in Azure AI Search correctly. When the method transforms a search result into a `Document` object, an "answer" key is added to the document's metadata. The value for this "answer" key should be the semantic answer returned by the search from this document, if such an answer is returned. The match between a `Document` object and the semantic answers returned by the search should be done through the unique document id, which is used as a key for the `semantic_answers_dict` dictionary. This id is defined in the search result's field named `FIELDS_ID`. I added a check to avoid any error in case no field named `FIELDS_ID` exists in a search result (which shouldn't happen in theory). A benefit of this approach is that this fix should work whether or not the Azure AI Search Index contains a metadata field. @levalencia could you confirm my analysis and test the fix? @raunakshrivastava7 do you agree with the fix?

For example, this causes it unable to parse the `https://python.langchain.com/docs`, as it returns the 404 page, and `https://python.langchain.com/docs/get_started/introduction` has no child routes to parse. `base_url` allows setting the `https://python.langchain.com/docs` to filter by, while the starting URL is anything inside, that contains relevant links to continue crawling. I understand that for this case, the docusaurus loader could be used, but it's a common issue with many websites. --------- Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	5 months ago

Chris Papademetrious	305d74c67a	core: implement a batch_size parameter for CacheBackedEmbeddings (#18070 ) Description: Currently, `CacheBackedEmbeddings` computes vectors for all uncached documents before updating the store. This pull request updates the embedding computation loop to compute embeddings in batches, updating the store after each batch. I noticed this when I tried `CacheBackedEmbeddings` on our 30k document set and the cache directory hadn't appeared on disk after 30 minutes. The motivation is to minimize compute/data loss when problems occur: * If there is a transient embedding failure (e.g. a network outage at the embedding endpoint triggers an exception), at least the completed vectors are written to the store instead of being discarded. * If there is an issue with the store (e.g. no write permissions), the condition is detected early without computing (and discarding!) all the vectors. Issue: Implements enhancement #18026. Testing: I was unable to run unit tests; details in [this post](https://github.com/langchain-ai/langchain/discussions/15019#discussioncomment-8576684). --------- Signed-off-by: chrispy <chrispy@synopsys.com> Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>	5 months ago
