Clément Sicard	1b48d6cb8c	`LlamaCppEmbeddings`: adds `verbose` parameter, similar to `llms.LlamaCpp` class (#11038) ... ## 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, ) ``` Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Michael Landis	a8db594012	fix: short-circuit black and mypy calls when no changes made (#11051) ... 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.	1 year ago

Eugene Yurtsev	b05bb9e136	LangServe (#11046) ... 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) --------- Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com>	1 year ago
Nuno Campos	77ce9ed6f1	Support using async callback handlers with sync callback manager (#10945) ... The current behaviour just calls the handler without awaiting the coroutine, which results in exceptions/warnings, and obviously doesn't actually execute whatever the callback handler does <!-- Thank you for contributing to LangChain!

Jonathan Evans	23065f54c0	Added prompt wrapping for Claude with Bedrock (#11090) ... - **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. - **Issue:** No issue opened at the moment, though will update when these roll in. - **Dependencies:** None --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago
xiaoyu	b87cc8b31e	add 3 property types in metadata for notiondb loader (#8509) ... ### Description: NotionDB supports a number of common property types. I have found three common types that are not included in notiondb loader. When programs loaded them with notiondb, which will cause some metadata information not to be passed to langchain. Therefore, I added three common types: - date - created_time - last_edit_time. ### Issue: no ### Dependencies: No dependencies added :) ### Tag maintainer: @rlancemartin, @eyurtsev ### Twitter handle: @BJTUTC	1 year ago
