This does not involve a separator, and will naively chunk input text at the appropriate boundaries in token space. This is helpful if we have strict token length limits that we need to strictly follow the specified chunk size, and we can't use aggressive separators like spaces to guarantee the absence of long strings. CharacterTextSplitter will let these strings through without splitting them, which could cause overflow errors downstream. Splitting at arbitrary token boundaries is not ideal but is hopefully mitigated by having a decent overlap quantity. Also this results in chunks which has exact number of tokens desired, instead of sometimes overcounting if we concatenate shorter strings. Potentially also helps with langchain-ai#528.
add ability to retry when certain exceptions are raised by `openai.Completions.create` Test plan: ran all OpenAI integration tests.

Just noticed this little typo while reading the docs, thought I'd open a PR!
The re.DOTALL flag in Python's re (regular expression) module makes the . (dot) metacharacter match newline characters as well as any other character. Without re.DOTALL, the . metacharacter only matches any character except for a newline character. With re.DOTALL, the . metacharacter matches any character, including newline characters.
Was passing prompt in directly as string and getting nonsense outputs. Had to inspect source code to realize that first arg should be a list. Could be nice if there was an explicit error or warning, seems like this could be a common mistake.
PR to fix outdated environment details in the docs, see issue langchain-ai#897 I added code comments as pointers to where users go to get API keys, and where they can find the relevant environment variable.

…angchain-ai#1187) Fixes issue langchain-ai#1186. For some reason, langchain-ai#1117 didn't seem to fix it.
### Description This PR adds a wrapper which adds support for the OpenSearch vector database. Using opensearch-py client we are ingesting the embeddings of given text into opensearch cluster using Bulk API. We can perform the `similarity_search` on the index using the 3 popular searching methods of OpenSearch k-NN plugin: - `Approximate k-NN Search` use approximate nearest neighbor (ANN) algorithms from the [nmslib](https://github.com/nmslib/nmslib), [faiss](https://github.com/facebookresearch/faiss), and [Lucene](https://lucene.apache.org/) libraries to power k-NN search. - `Script Scoring` extends OpenSearch’s script scoring functionality to execute a brute force, exact k-NN search. - `Painless Scripting` adds the distance functions as painless extensions that can be used in more complex combinations. Also, supports brute force, exact k-NN search like Script Scoring. ### Issues Resolved langchain-ai#1054 --------- Signed-off-by: Naveen Tatikonda <[email protected]>
Lets a chain prompt the user for more input as a part of its execution.
Added a GitBook document loader. It lets you both, (1) fetch text from any single GitBook page, or (2) fetch all relative paths and return their respective content in Documents. I've modified the `scrape` method in the `WebBaseLoader` to accept custom web paths if given, but happy to remove it and move that logic into the `GitbookLoader` itself.
For persistence, it's convenient to have a default collection name which gets used everywhere.
langchain-ai#1153) It is useful to be able to specify `verbose` or `memory` while still keeping the chain's overall structure. --------- Co-authored-by: Francisco Ingham <>

When I try to import the Class HuggingFaceEndpoint I get an Import Error: cannot import name 'HuggingFaceEndpoint' from 'langchain'. (langchain version 0.0.88) These two imports work fine: from langchain import HuggingFacePipeline and from langchain import HuggingFaceHub. So I corrected the import statement in the example. There is probably a better solution to this, but this fixes the Error for me.
