Kacper Łukawski	d4f719c34b	Convert numpy arrays to lists in HuggingFaceEmbeddings (#714) ... `SentenceTransformer` returns a NumPy array, not a `List[List[float]]` or `List[float]` as specified in the interface of `Embeddings`. That PR makes it consistent with the interface.	1 year ago
Kacper Łukawski	97c3544a1e	Hotfix: Qdrant.from_text embeddings (#713) ... I'm providing a hotfix for Qdrant integration. Calculating a single embedding to obtain the vector size was great idea. However, that change introduced a bug trying to put only that single embedding into the database. It's fixed. Right now all the embeddings will be pushed to Qdrant.	1 year ago

Scott Leibrand	34932dd211	remove legacy embedding model name (#703) ... Now that OpenAI has deprecated all embeddings models except text-embedding-ada-002, we should stop specifying a legacy embedding model in the example. This will also avoid confusion from people (like me) trying to specify model="text-embedding-ada-002" and having that erroneously expanded to text-search-text-embedding-ada-002-query-001	1 year ago

xloem	36b6b3cdf6	HuggingFacePipeline: Forward model_kwargs. (#696) ... Since the tokenizer and model are constructed manually, model_kwargs needs to be passed to their constructors. Additionally, the pipeline has a specific named parameter to pass these with, which can provide forward compatibility if they are used for something other than tokenizer or model construction.	1 year ago

vertinski	65f3a341b0	Prompt fix for empty intermediate steps in summarization (#660) ... Adding quotation marks around {text} avoids generating empty or completely random responses from OpenAI davinci-003. Empty or completely unrelated intermediate responses in summarization messes up the final result or makes it very inaccurate. The error from OpenAI would be: "The model predicted a completion that begins with a stop sequence, resulting in no output. Consider adjusting your prompt or stop sequences." This fix corrects the prompting for summarization chain. This works on API too, the images are for demonstrative purposes. This approach can be applied to other similar prompts too. Examples: 1) Without quotation marks  2) With quotation marks 	1 year ago

Nicolas	91d7fd20ae	feat: add custom prompt for QAEvalChain chain (#610) ... I originally had only modified the `from_llm` to include the prompt but I realized that if the prompt keys used on the custom prompt didn't match the default prompt, it wouldn't work because of how `apply` works. So I made some changes to the evaluate method to check if the prompt is the default and if not, it will check if the input keys are the same as the prompt key and update the inputs appropriately. Let me know if there is a better way to do this. Also added the custom prompt to the QA eval notebook.	1 year ago

Yongtae723	f48ab642be	replace forbid into ignore (#539) ... this is the second PR of #519. in #519 I suggested deleting Extra.forbid. I was very confused but I replaced Extra.forbid to Extra.ignore, which is the default of pydantic. Since the [BaseLLM](4b7b8229de/langchain/llms/base.py (L20)) from which it is inherited is set in Extra.forbid, I wanted to avoid having the Extra.forbid settings inherited by simply deleting it.	1 year ago
Yongtae723	4b7b8229de	add logger (#529) ... As talking #519, I made 2 PRs. this is the first PR for adding a logger. I am concerned about the following two points and would appreciate your opinion. 1. Since the logger is not formatted, the statement itself is output like a print statement, and I thought it was difficult to understand that it was a warning, so I put WARNING! at the beginning of the warning statement. After the logger formatting is done properly, the word WARNING can be repeated. 2. Statement `Please confirm that {field_name} is what you intended.` can be replaced like `If {field_name} is intended parameters, enter it to model_kwargs` thank you! Yongtae	1 year ago

Harrison Chase	985496f4be	Docs refactor (#480) ... Big docs refactor! Motivation is to make it easier for people to find resources they are looking for. To accomplish this, there are now three main sections: - Getting Started: steps for getting started, walking through most core functionality - Modules: these are different modules of functionality that langchain provides. Each part here has a "getting started", "how to", "key concepts" and "reference" section (except in a few select cases where it didnt easily fit). - Use Cases: this is to separate use cases (like summarization, question answering, evaluation, etc) from the modules, and provide a different entry point to the code base. There is also a full reference section, as well as extra resources (glossary, gallery, etc) Co-authored-by: Shreya Rajpal <ShreyaR@users.noreply.github.com>	1 year ago

andersenchen	5267ebce2d	Add LLMCheckerChain (#281) ... Implementation of https://github.com/jagilley/fact-checker. Works pretty well. <img width="993" alt="Screenshot 2022-12-07 at 4 41 47 PM" src="https://user-images.githubusercontent.com/101075607/206302751-356a19ff-d000-4798-9aee-9c38b7f532b9.png"> Verifying this manually: 1. "Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater." https://www.scientificamerican.com/article/extreme-monotremes/ 2. "An [Echidna] egg weighs 1.5 to 2 grams (0.05 to 0.07 oz)[[19]](https://en.wikipedia.org/wiki/Echidna#cite_note-19) and is about 1.4 centimetres (0.55 in) long." https://en.wikipedia.org/wiki/Echidna#:~:text=sleep%20is%20suppressed.-,Reproduction,a%20reptile%2Dlike%20egg%20tooth. 3. "A [platypus] lays one to three (usually two) small, leathery eggs (similar to those of reptiles), about 11 mm (7⁄16 in) in diameter and slightly rounder than bird eggs." https://en.wikipedia.org/wiki/Platypus#:~:text=It%20lays%20one%20to%20three,slightly%20rounder%20than%20bird%20eggs. 4. Therefore, an Echidna is the mammal that lays the biggest eggs. cc @hwchase17	1 year ago

Samantha Whitmore	315b0c09c6	wip: add method for both docstore and embeddings (#119) ... this will break atm but wanted to get thoughts on implementation. 1. should add() be on docstore interface? 2. should InMemoryDocstore change to take a list of documents as init? (makes this slightly easier to implement in FAISS -- if we think it is less clean then could expose a method to get the number of documents currently in the dict, and perform the logic of creating the necessary dictionary in the FAISS.add_texts method.
