🚀 Features

Templates Supported

The Sinapsis Langchain module provides wrapper templates for Langchain's community data loaders, making them seamlessly usable within Sinapsis.

Note

Each loader template supports one attribute:

• add_document_as_text_packet (bool, default: False): Whether to add the loaded document as a text packet. Other attributes can be dynamically assigned through the class initialization dictionary (class init attributes).

Tip

Use CLI command sinapsis info --all-template-names to show a list with all the available Template names installed with Sinapsis Langchain.

Tip

Use CLI command sinapsis info --example-template-config TEMPLATE_NAME to produce an example Agent config for the Template specified in TEMPLATE_NAME.

For example, for WikipediaLoaderWrapper use sinapsis info --example-template-config WikipediaLoaderWrapper to produce the following example config:

agent:
  name: agent to load Wikipedia documents using WikipediaLoaderWrapper template
templates:
- template_name: InputTemplate
  class_name: InputTemplate
  attributes: {}
- template_name: WikipediaLoaderWrapper
  class_name: WikipediaLoaderWrapper
  template_input: InputTemplate
  attributes:
    add_document_as_text_packet: false
    wikipedialoader_init:
        query: the query for wikipedia
        lang: en
        load_max_docs: 5000
        load_all_available_meta: False
        doc_content_chars_max: 4000,

A complete list of available document loader classes in LangChain can be found at: LangChain Community Document Loaders
