Predrag Gruevski	aa3f4a9bc8	Remove the CLI package's pydantic compatibility tests. (#12675 ) They aren't necessary, since the CLI package doesn't have a direct dependency on pydantic.	11 months ago
Predrag Gruevski	e8b99364b3	Use `ruff` for both linting and formatting in `langchain-cli`. (#12672 ) Prior to this PR, `ruff` was used only for linting and not for formatting, despite the names of the commands. This PR makes it be used for both linting code and autoformatting it.	11 months ago

Noam Gat	14e8c74736	LM Format Enforcer Integration + Sample Notebook (#12625 ) ## Description This PR adds support for [lm-format-enforcer](https://github.com/noamgat/lm-format-enforcer) to LangChain. ![image](https://raw.githubusercontent.com/noamgat/lm-format-enforcer/main/docs/Intro.webp) The library is similar to jsonformer / RELLM which are supported in Langchain, but has several advantages such as - Batching and Beam search support - More complete JSON Schema support - LLM has control over whitespace, improving quality - Better runtime performance due to only calling the LLM's generate() function once per generate() call. The integration is loosely based on the jsonformer integration in terms of project structure. ## Dependencies No compile-time dependency was added, but if `lm-format-enforcer` is not installed, a runtime error will occur if it is trying to be used. ## Tests Due to the integration modifying the internal parameters of the underlying huggingface transformer LLM, it is not possible to test without building a real LM, which requires internet access. So, similar to the jsonformer and RELLM integrations, the testing is via the notebook. ## Twitter Handle [@noamgat](https://twitter.com/noamgat) Looking forward to hearing feedback! --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	11 months ago
Stefano Lottini	a4e4b5a86f	Relax python version and remove need for explicit setup step (#12637 ) This PR addresses what seems like a unnecessary Python version restriction in the pyroject.toml specs within both Cassandra (/Astra DB) templates. With "^3.11" I got some version incompatibilities with the latest "langchain add [...]" commands, so these are now relaxed in line with the other templates I could inspect. Incidentally, in the "entomology" template, the need for an explicit "setup" step for the user to carry on has been removed, replaced by a check-and-execute-if-necessary instruction on app startup. Thank you for your attention!	11 months ago

Predrag Gruevski	f94e24dfd7	Install and use `ruff format` instead of black for code formatting. (#12585 ) Best to review one commit at a time, since two of the commits are 100% autogenerated changes from running `ruff format`: - Install and use `ruff format` instead of black for code formatting. - Output of `ruff format .` in the `langchain` package. - Use `ruff format` in experimental package. - Format changes in experimental package by `ruff format`. - Manual formatting fixes to make `ruff .` pass.	11 months ago
William FH	bfd719f9d8	bind_functions convenience method (#12518 ) I always take 20-30 seconds to re-discover where the `convert_to_openai_function` wrapper lives in our codebase. Chat langchain [has no clue](https://smith.langchain.com/public/3989d687-18c7-4108-958e-96e88803da86/r) what to do either. There's the older `create_openai_fn_chain` , but we haven't been recommending it in LCEL. The example we show in the [cookbook](https://python.langchain.com/docs/expression_language/how_to/binding#attaching-openai-functions) is really verbose. General function calling should be as simple as possible to do, so this seems a bit more ergonomic to me (feel free to disagree). Another option would be to directly coerce directly in the class's init (or when calling invoke), if provided. I'm not 100% set against that. That approach may be too easy but not simple. This PR feels like a decent compromise between simple and easy. ``` from enum import Enum from typing import Optional from pydantic import BaseModel, Field class Category(str, Enum): """The category of the issue.""" bug = "bug" nit = "nit" improvement = "improvement" other = "other" class IssueClassification(BaseModel): """Classify an issue.""" category: Category other_description: Optional[str] = Field( description="If classified as 'other', the suggested other category" ) from langchain.chat_models import ChatOpenAI llm = ChatOpenAI().bind_functions([IssueClassification]) llm.invoke("This PR adds a convenience wrapper to the bind argument") # AIMessage(content='', additional_kwargs={'function_call': {'name': 'IssueClassification', 'arguments': '{\n "category": "improvement"\n}'}}) ```	11 months ago
