Nante Nantero	41047fe4c3	fix(DynamoDBChatMessageHistory): correct delete_item method call (#10383 ) Description: Fixed a bug introduced in version 0.0.281 in `DynamoDBChatMessageHistory` where `self.table.delete_item(self.key)` produced a TypeError: `TypeError: delete_item() only accepts keyword arguments`. Updated the method call to `self.table.delete_item(Key=self.key)` to resolve this issue. Please see also [the official AWS documentation](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/dynamodb/table/delete_item.html#) on this delete_item method - only `kwargs` are accepted. See also the PR, which introduced this bug: https://github.com/langchain-ai/langchain/pull/9896#discussion_r1317899073 Please merge this, I rely on this delete dynamodb item functionality (because of GDPR considerations).

James Barney	50128c8b39	Adding File-Like object support in CSV Agent Toolkit (#10409 ) If loading a CSV from a direct or temporary source, loading the file-like object (subclass of IOBase) directly allows the agent creation process to succeed, instead of throwing a ValueError. Added an additional elif and tweaked value error message. Added test to validate this functionality. Pandas from_csv supports this natively but this current implementation only accepts strings or paths to files. https://pandas.pydata.org/docs/user_guide/io.html#io-read-csv-table --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Michael Haddad	c6b27b3692	add konko chat_model files (#10267 ) _Thank you to the LangChain team for the great project and in advance for your review. Let me know if I can provide any other additional information or do things differently in the future to make your lives easier 🙏 _ @hwchase17 please let me know if you're not the right person to review 😄 This PR enables LangChain to access the Konko API via the chat_models API wrapper. Konko API is a fully managed API designed to help application developers: 1. Select the right LLM(s) for their application 2. Prototype with various open-source and proprietary LLMs 3. Move to production in-line with their security, privacy, throughput, latency SLAs without infrastructure set-up or administration using Konko AI's SOC 2 compliant infrastructure _Note on integration tests:_ We added 14 integration tests. They will all fail unless you export the right API keys. 13 will pass with a KONKO_API_KEY provided and the other one will pass with a OPENAI_API_KEY provided. When both are provided, all 14 integration tests pass. If you would like to test this yourself, please let me know and I can provide some temporary keys. ### Installation and Setup 1. First you'll need an API key 2. Install Konko AI's Python SDK 1. Enable a Python3.8+ environment `pip install konko` 3. Set API Keys Option 1: Set Environment Variables You can set environment variables for 1. KONKO_API_KEY (Required) 2. OPENAI_API_KEY (Optional) In your current shell session, use the export command: `export KONKO_API_KEY={your_KONKO_API_KEY_here}` `export OPENAI_API_KEY={your_OPENAI_API_KEY_here} #Optional` Alternatively, you can add the above lines directly to your shell startup script (such as .bashrc or .bash_profile for Bash shell and .zshrc for Zsh shell) to have them set automatically every time a new shell session starts. Option 2: Set API Keys Programmatically If you prefer to set your API keys directly within your Python script or Jupyter notebook, you can use the following commands: ```python konko.set_api_key('your_KONKO_API_KEY_here') konko.set_openai_api_key('your_OPENAI_API_KEY_here') # Optional ``` ### Calling a model Find a model on the [[Konko Introduction page](https://docs.konko.ai/docs#available-models)](https://docs.konko.ai/docs#available-models) For example, for this [[LLama 2 model](https://docs.konko.ai/docs/meta-llama-2-13b-chat)](https://docs.konko.ai/docs/meta-llama-2-13b-chat). The model id would be: `"meta-llama/Llama-2-13b-chat-hf"` Another way to find the list of models running on the Konko instance is through this [[endpoint](https://docs.konko.ai/reference/listmodels)](https://docs.konko.ai/reference/listmodels). From here, we can initialize our model: ```python chat_instance = ChatKonko(max_tokens=10, model = 'meta-llama/Llama-2-13b-chat-hf') ``` And run it: ```python msg = HumanMessage(content="Hi") chat_response = chat_instance([msg]) ```	1 year ago

maks-operlejn-ds	274c3dc3a8	Multilingual anonymization (#10327 ) ### Description Add multiple language support to Anonymizer PII detection in Microsoft Presidio relies on several components - in addition to the usual pattern matching (e.g. using regex), the analyser uses a model for Named Entity Recognition (NER) to extract entities such as: - `PERSON` - `LOCATION` - `DATE_TIME` - `NRP` - `ORGANIZATION` [[Source]](https://github.com/microsoft/presidio/blob/main/presidio-analyzer/presidio_analyzer/predefined_recognizers/spacy_recognizer.py) To handle NER in specific languages, we utilize unique models from the `spaCy` library, recognized for its extensive selection covering multiple languages and sizes. However, it's not restrictive, allowing for integration of alternative frameworks such as [Stanza](https://microsoft.github.io/presidio/analyzer/nlp_engines/spacy_stanza/) or [transformers](https://microsoft.github.io/presidio/analyzer/nlp_engines/transformers/) when necessary. ### Future works - automatic language detection - instead of passing the language as a parameter in `anonymizer.anonymize`, we could detect the language/s beforehand and then use the corresponding NER model. We have discussed this internally and @mateusz-wosinski-ds will look into a standalone language detection tool/chain for LangChain 😄 ### Twitter handle @deepsense_ai / @MaksOpp ### Tag maintainer @baskaryan @hwchase17 @hinthornw	1 year ago
