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>	12 months 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.	12 months ago

Matvey Arye	6e02c45ca4	Add integration for Timescale Vector(Postgres) (#10650 ) Description: This commit adds a vector store for the Postgres-based vector database (`TimescaleVector`). Timescale Vector(https://www.timescale.com/ai) is PostgreSQL++ for AI applications. It enables you to efficiently store and query billions of vector embeddings in `PostgreSQL`: - Enhances `pgvector` with faster and more accurate similarity search on 1B+ vectors via DiskANN inspired indexing algorithm. - Enables fast time-based vector search via automatic time-based partitioning and indexing. - Provides a familiar SQL interface for querying vector embeddings and relational data. Timescale Vector scales with you from POC to production: - Simplifies operations by enabling you to store relational metadata, vector embeddings, and time-series data in a single database. - Benefits from rock-solid PostgreSQL foundation with enterprise-grade feature liked streaming backups and replication, high-availability and row-level security. - Enables a worry-free experience with enterprise-grade security and compliance. Timescale Vector is available on Timescale, the cloud PostgreSQL platform. (There is no self-hosted version at this time.) LangChain users get a 90-day free trial for Timescale Vector. --------- Co-authored-by: Bagatur <baskaryan@gmail.com> Co-authored-by: Avthar Sewrathan <avthar@timescale.com>	1 year ago
