DeadBranch	8fa1764c60	docs: update gpt index references to LlamaIndex (#1856 ) The GPT Index project is transitioning to the new project name, LlamaIndex. I've updated a few files referencing the old project name and repository URL to the current ones. From the [LlamaIndex repo](https://github.com/jerryjliu/llama_index): > NOTE: We are rebranding GPT Index as LlamaIndex! We will carry out this transition gradually. > > 2/25/2023: By default, our docs/notebooks/instructions now reference "LlamaIndex" instead of "GPT Index". > > 2/19/2023: By default, our docs/notebooks/instructions now use the llama-index package. However the gpt-index package still exists as a duplicate! > > 2/16/2023: We have a duplicate llama-index pip package. Simply replace all imports of gpt_index with llama_index if you choose to pip install llama-index. I'm not associated with LlamaIndex in any way. I just noticed the discrepancy when studying the lanchain documentation.	2 years ago

Philipp Schmid	064be93edf	[Embeddings] Add SageMaker Endpoint Embedding class (#1859 ) # What does this PR do? This PR adds similar to `llms` a SageMaker-powered `embeddings` class. This is helpful if you want to leverage Hugging Face models on SageMaker for creating your indexes. I added a example into the [docs/modules/indexes/examples/embeddings.ipynb](https://github.com/hwchase17/langchain/compare/master...philschmid:add-sm-embeddings?expand=1#diff-e82629e2894974ec87856aedd769d4bdfe400314b03734f32bee5990bc7e8062) document. The example currently includes some `_### TEMPORARY: Showing how to deploy a SageMaker Endpoint from a Hugging Face model ###_ ` code showing how you can deploy a sentence-transformers to SageMaker and then run the methods of the embeddings class. @hwchase17 please let me know if/when i should remove the `_### TEMPORARY: Showing how to deploy a SageMaker Endpoint from a Hugging Face model ###_` in the description i linked to a detail blog on how to deploy a Sentence Transformers so i think we don't need to include those steps here. I also reused the `ContentHandlerBase` from `langchain.llms.sagemaker_endpoint` and changed the output type to `any` since it is depending on the implementation.	2 years ago

Matt Tucker	a92344f476	Use regex match for bash process error output test assertion. (#1837 ) I was getting the same issue reported in #1339 by [MacYang555](https://github.com/MacYang555) when running the test suite on my Mac. I implemented the fix they suggested to use a regex match in the output assertion for the scenario under test. Resolves #1339	2 years ago
Tomoko Uchida	b706966ebc	Add setup instruction in Getting Started for Indexing (#1847 ) `VectorstoreIndexCreator` [uses Chroma as the vectorstore by default](`1c22657256/langchain/indexes/vectorstore.py (L49)`). It may be helpful to add a short note for the setup.

Wenbin Fang	a7e09d46c5	Add podcast api tool to use NLP to search all podcasts or episodes. (#1833 ) Use the following code to test: ```python import os from langchain.llms import OpenAI from langchain.chains.api import podcast_docs from langchain.chains import APIChain # Get api key here: https://openai.com/pricing os.environ["OPENAI_API_KEY"] = "sk-xxxxx" # Get api key here: https://www.listennotes.com/api/pricing/ listen_api_key = 'xxx' llm = OpenAI(temperature=0) headers = {"X-ListenAPI-Key": listen_api_key} chain = APIChain.from_llm_and_api_docs(llm, podcast_docs.PODCAST_DOCS, headers=headers, verbose=True) chain.run("Search for 'silicon valley bank' podcast episodes, audio length is more than 30 minutes, return only 1 results") ``` Known issues: the api response data might be too big, and we'll get such error: `openai.error.InvalidRequestError: This model's maximum context length is 4097 tokens, however you requested 6733 tokens (6477 in your prompt; 256 for the completion). Please reduce your prompt; or completion length.`	2 years ago
Matt Tucker	fa2e546b76	Add workaround for debugpy install issue to contrib docs. (#1835 ) When following the Quick Start instructions in the contributing docs, I was getting a "WheelFileValidationError" on installation of debugpy which was blocking the installation of a number of other deps. Google turned up this [GitHub issue](https://github.com/microsoft/debugpy/issues/1246) indicating a regression in Poetry 1.4.1 and workarounds. This PR updates the contrib docs noting the issue and the workarounds.	2 years ago

Bernat Felip i Díaz	262d4cb9a8	Use embedding instead of embedding function in ElasticVectorStore (#1692 ) While it might be a bit more restrictive, I find that using the Embedding interface as an input for the vector store creation is better than an embedding function because we can use bulk requests and possibly the retry logic if needed. I have seen that some vector store implementations use Embedding while others use embedding function so I don't know what is the criteria to have one or the other, in my opinion they should all just be Embedding or have a way more complex embedding function that accepts multiple texts instead of one by one. --------- Co-authored-by: Bernat Felip <bernat.felip@rea.ch>	2 years ago

(#1753 ) Regarding [this issue](https://github.com/hwchase17/langchain/issues/1754), the code in the document [Creating a custom prompt template](https://langchain.readthedocs.io/en/latest/modules/prompts/examples/custom_prompt_template.html) is no longer functional and outdated. To address this, I have made the following changes: 1. Updated the guide in the document to use `StringPromptTemplate` instead of `BasePromptTemplate`. 2. Exposed `StringPromptTemplate` in `prompts/__init__.py` for easier importing.	2 years ago
hitoshi44	e635c86145	Slightly modified the docstring in `BasePromptTemplate` and `StringPromptTemplate`. (#1755 ) Regarding [this issue](https://github.com/hwchase17/langchain/issues/1754), `BasePromptTample` class docstring is a little outdated, thus it requires new method `format_prompt` for now. As such, I have made some modifications to the docstring to bring it up to date. I tried to adhere to the established document style, and would appreciate you for taking a look at this PR.	2 years ago

LeoGrin	3701b2901e	use namespace argument in Pinecone constructor (#1757 ) Fix #1756 Use the `namespace` argument of `Pinecone.from_exisiting_index` to set the default value of `namespace` for other methods. Leads to more expected behavior and easier integration in chains. For the test, I've added a line to delete and rebuild the `langchain-demo` index at the beginning of the test. I'm not 100% sure if it's a good idea but it makes the test reproducible.	2 years ago
