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
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

Nikhil Jha	dff24285ea	Comprehend Moderation 0.2 (#11730 ) This PR replaces the previous `Intent` check with the new `Prompt Safety` check. The logic and steps to enable chain moderation via the Amazon Comprehend service, allowing you to detect and redact PII, Toxic, and Prompt Safety information in the LLM prompt or answer remains unchanged. This implementation updates the code and configuration types with respect to `Prompt Safety`. ### Usage sample ```python from langchain_experimental.comprehend_moderation import (BaseModerationConfig, ModerationPromptSafetyConfig, ModerationPiiConfig, ModerationToxicityConfig ) pii_config = ModerationPiiConfig( labels=["SSN"], redact=True, mask_character="X" ) toxicity_config = ModerationToxicityConfig( threshold=0.5 ) prompt_safety_config = ModerationPromptSafetyConfig( threshold=0.5 ) moderation_config = BaseModerationConfig( filters=[pii_config, toxicity_config, prompt_safety_config] ) comp_moderation_with_config = AmazonComprehendModerationChain( moderation_config=moderation_config, #specify the configuration client=comprehend_client, #optionally pass the Boto3 Client verbose=True ) template = """Question: {question} Answer:""" prompt = PromptTemplate(template=template, input_variables=["question"]) responses = [ "Final Answer: A credit card number looks like 1289-2321-1123-2387. A fake SSN number looks like 323-22-9980. John Doe's phone number is (999)253-9876.", "Final Answer: This is a really shitty way of constructing a birdhouse. This is fucking insane to think that any birds would actually create their motherfucking nests here." ] llm = FakeListLLM(responses=responses) llm_chain = LLMChain(prompt=prompt, llm=llm) chain = ( prompt \| comp_moderation_with_config \| {llm_chain.input_keys[0]: lambda x: x['output'] } \| llm_chain \| { "input": lambda x: x['text'] } \| comp_moderation_with_config ) try: response = chain.invoke({"question": "A sample SSN number looks like this 123-456-7890. Can you give me some more samples?"}) except Exception as e: print(str(e)) else: print(response['output']) ``` ### Output ```python > Entering new AmazonComprehendModerationChain chain... Running AmazonComprehendModerationChain... Running pii Validation... Running toxicity Validation... Running prompt safety Validation... > Finished chain. > Entering new AmazonComprehendModerationChain chain... Running AmazonComprehendModerationChain... Running pii Validation...

Predrag Gruevski	392df7b2e3	Type hints on varargs and kwargs that take anything should be `Any`. (#11950 ) Type hinting `args` as `List[Any]` means that each positional argument should be a list. Type hinting `*kwargs` as `Dict[str, Any]` means that each keyword argument should be a dict of strings. This is almost never what we actually wanted, and doesn't seem to be what we want in any of the cases I'm replacing here.	11 months ago

Qihui Xie	57ade13b2b	fix llm_inputs duplication problem in intermediate_steps in SQLDatabaseChain (#10279 ) Use `.copy()` to fix the bug that the first `llm_inputs` element is overwritten by the second `llm_inputs` element in `intermediate_steps`. *Problem description:* In [line 127]( `c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L127C17-L127C17)`), the `llm_inputs` of the sql generation step is appended as the first element of `intermediate_steps`: ``` intermediate_steps.append(llm_inputs) # input: sql generation ``` However, `llm_inputs` is a mutable dict, it is updated in [line 179](https://github.com/langchain-ai/langchain/blob/master/libs/experimental/langchain_experimental/sql/base.py#L179) for the final answer step: ``` llm_inputs["input"] = input_text ``` Then, the updated `llm_inputs` is appended as another element of `intermediate_steps` in [line 180](`c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L180)`): ``` intermediate_steps.append(llm_inputs) # input: final answer ``` As a result, the final `intermediate_steps` returned in [line 189](`c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L189C43-L189C43)`) actually contains two same `llm_inputs` elements, i.e., the `llm_inputs` for the sql generation step overwritten by the one for final answer step by mistake. Users are not able to get the actual `llm_inputs` for the sql generation step from `intermediate_steps` Simply calling `.copy()` when appending `llm_inputs` to `intermediate_steps` can solve this problem.	11 months ago

olgavrou	3b07c0cf3d	RL Chain with VowpalWabbit (#10242 ) - Description: This PR adds a new chain `rl_chain.PickBest` for learned prompt variable injection, detailed description and usage can be found in the example notebook added. It essentially adds a [VowpalWabbit](https://github.com/VowpalWabbit/vowpal_wabbit) layer before the llm call in order to learn or personalize prompt variable selections. Most of the code is to make the API simple and provide lots of defaults and data wrangling that is needed to use Vowpal Wabbit, so that the user of the chain doesn't have to worry about it. - Dependencies: [vowpal-wabbit-next](https://pypi.org/project/vowpal-wabbit-next/), - sentence-transformers (already a dep) - numpy (already a dep) - tagging @ataymano who contributed to this chain - Tag maintainer: @baskaryan - Twitter handle: @olgavrou Added example notebook and unit tests	11 months ago
maks-operlejn-ds	2aae1102b0	Instance anonymization (#10501 ) ### Description Add instance anonymization - if `John Doe` will appear twice in the text, it will be treated as the same entity. The difference between `PresidioAnonymizer` and `PresidioReversibleAnonymizer` is that only the second one has a built-in memory, so it will remember anonymization mapping for multiple texts: ``` >>> anonymizer = PresidioAnonymizer() >>> anonymizer.anonymize("My name is John Doe. Hi John Doe!") 'My name is Noah Rhodes. Hi Noah Rhodes!' >>> anonymizer.anonymize("My name is John Doe. Hi John Doe!") 'My name is Brett Russell. Hi Brett Russell!' ``` ``` >>> anonymizer = PresidioReversibleAnonymizer() >>> anonymizer.anonymize("My name is John Doe. Hi John Doe!") 'My name is Noah Rhodes.
