Mike McGarry	ddd595fe81	feature/4493 Improve Evernote Document Loader (#4577 ) # Improve Evernote Document Loader When exporting from Evernote you may export more than one note. Currently the Evernote loader concatenates the content of all notes in the export into a single document and only attaches the name of the export file as metadata on the document. This change ensures that each note is loaded as an independent document and all available metadata on the note e.g. author, title, created, updated are added as metadata on each document. It also uses an existing optional dependency of `html2text` instead of `pypandoc` to remove the need to download the pandoc application via `download_pandoc()` to be able to use the `pypandoc` python bindings.

Eugene Yurtsev	06e524416c	power bi api wrapper integration tests & bug fix (#4983 ) # Powerbi API wrapper bug fix + integration tests - Bug fix by removing `TYPE_CHECKING` in in utilities/powerbi.py - Added integration test for power bi api in utilities/test_powerbi_api.py - Added integration test for power bi agent in agent/test_powerbi_agent.py - Edited .env.examples to help set up power bi related environment variables - Updated demo notebook with working code in docs../examples/powerbi.ipynb - AzureOpenAI -> ChatOpenAI Notes: Chat models (gpt3.5, gpt4) are much more capable than davinci at writing DAX queries, so that is important to getting the agent to work properly. Interestingly, gpt3.5-turbo needed the examples=DEFAULT_FEWSHOT_EXAMPLES to write consistent DAX queries, so gpt4 seems necessary as the smart llm. Fixes #4325 ## Before submitting Azure-core and Azure-identity are necessary dependencies check integration tests with the following: `pytest tests/integration_tests/utilities/test_powerbi_api.py` `pytest tests/integration_tests/agent/test_powerbi_agent.py` You will need a power bi account with a dataset id + table name in order to test.

Parses the semantic XML into chunks, with additional metadata capturing chunk semantics 3. Adds a detailed notebook showing how you can use additional metadata returned by Docugami for techniques like the [self-querying retriever](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/self_query_retriever.html) 4.

Li Yuanzheng	3b6206af49	Respect User-Specified User-Agent in WebBaseLoader (#4579 ) # Respect User-Specified User-Agent in WebBaseLoader This pull request modifies the `WebBaseLoader` class initializer from the `langchain.document_loaders.web_base` module to preserve any User-Agent specified by the user in the `header_template` parameter. Previously, even if a User-Agent was specified in `header_template`, it would always be overridden by a random User-Agent generated by the `fake_useragent` library. With this change, if a User-Agent is specified in `header_template`, it will be used. Only in the case where no User-Agent is specified will a random User-Agent be generated and used. This provides additional flexibility when using the `WebBaseLoader` class, allowing users to specify their own User-Agent if they have a specific need or preference, while still providing a reasonable default for cases where no User-Agent is specified. This change has no impact on existing users who do not specify a User-Agent, as the behavior in this case remains the same. However, for users who do specify a User-Agent, their choice will now be respected and used for all subsequent requests made using the `WebBaseLoader` class.

Samuli Rauatmaa	66828ad231	add the existing OpenWeatherMap tool to the public api (#4292 ) [OpenWeatherMapAPIWrapper](`f70e18a5b3/docs/modules/agents/tools/examples/openweathermap.ipynb`) works wonderfully, but the _tool_ itself can't be used in master branch. - added OpenWeatherMap tool to the public api, to be loadable with `load_tools` by using "openweathermap-api" tool name (that name is used in the existing [docs](`aff33d52c5/docs/modules/agents/tools/getting_started.md`), at the bottom of the page) - updated OpenWeatherMap tool's description to make the input format match what the API expects (e.g. `London,GB` instead of `'London,GB'`) - added [ecosystem documentation page for OpenWeatherMap](`f9c41594fe/docs/ecosystem/openweathermap.md`) - added tool usage example to [OpenWeatherMap's notebook](`f9c41594fe/docs/modules/agents/tools/examples/openweathermap.ipynb`) Let me know if there's something I missed or something needs to be updated!

Prerit Das	2747ccbcf1	Allow custom base Zapier prompt (#4213 ) Currently, all Zapier tools are built using the pre-written base Zapier prompt. These small changes (that retain default behavior) will allow a user to create a Zapier tool using the ZapierNLARunTool while providing their own base prompt. Their prompt must contain input fields for zapier_description and params, checked and enforced in the tool's root validator. An example of when this may be useful: user has several, say 10, Zapier tools enabled. Currently, the long generic default Zapier base prompt is attached to every single tool, using an extreme number of tokens for no real added benefit (repeated). User prompts LLM on how to use Zapier tools once, then overrides the base prompt. Or: user has a few specific Zapier tools and wants to maximize their success rate. So, user writes prompts/descriptions for those tools specific to their use case, and provides those to the ZapierNLARunTool. A consideration - this is the simplest way to implement this I could think of... though ideally custom prompting would be possible at the Toolkit level as well. For now, this should be sufficient in solving the concerns outlined above.	1 year ago
Paresh Mathur	e2bc836571	Fix #4087 by setting the correct csv dialect (#4103 ) The error in #4087 was happening because of the use of csv.Dialect.* which is just an empty base class. we need to make a choice on what is our base dialect. I usually use excel so I put it as excel, if maintainers have other preferences do let me know. Open Questions: 1. What should be the default dialect? 2. Should we rework all tests to mock the open function rather than the csv.DictReader? 3. Should we make a separate input for `dialect` like we have for `encoding`? --------- Co-authored-by: = <=>	1 year ago

Zander Chase	0c6ed657ef	Convert Chain to a Chain Factory (#4605 ) ## Change Chain argument in client to accept a chain factory The `run_over_dataset` functionality seeks to treat each iteration of an example as an independent trial. Chains have memory, so it's easier to permit this type of behavior if we accept a factory method rather than the chain object directly. There's still corner cases / UX pains people will likely run into, like: - Caching may cause issues - if memory is persisted to a shared object (e.g., same redis queue) , this could impact what is retrieved - If we're running the async methods with concurrency using local models, if someone naively instantiates the chain and loads each time, it could lead to tons of disk I/O or OOM	1 year ago

Roma	d15f481352	Add unit test to output parsers (#3911 ) This pull request adds unit tests for various output parsers (BooleanOutputParser, CommaSeparatedListOutputParser, and StructuredOutputParser) to ensure their correct functionality and to increase code reliability and maintainability. The tests cover both valid and invalid input cases. Changes: Added unit tests for BooleanOutputParser. Added unit tests for CommaSeparatedListOutputParser. Added unit tests for StructuredOutputParser. Testing: All new unit tests have been executed, and they pass successfully. The overall test suite has been run, and all tests pass. Notes: These tests cover both successful parsing scenarios and error handling for invalid inputs. If any new output parsers are added in the future, corresponding unit tests should also be created to maintain coverage.	1 year ago

Mike Wang	512c24fc9c	[annotation improvement] Make AgentType->Class Conversion More Scalable (#3749 ) In the current solution, AgentType and AGENT_TO_CLASS are placed in two separate files and both manually maintained. This might cause inconsistency when we update either of them. — latest — based on the discussion with hwchase17, we don’t know how to further use the newly introduced AgentTypeConfig type, so it doesn’t make sense yet to add it. Instead, it’s better to move the dictionary to another file to keep the loading.py file clear. The consistency is a good point. Instead of asserting the consistency during linting, we added a unittest for consistency check. I think it works as auto unittest is triggered every time with clear failure notice. (well, force push is possible, but we all know what we are doing, so let’s show trust. :>) ~~This PR includes~~ - ~~Introduced AgentTypeConfig as the source of truth of all AgentType related meta data.~~ - ~~Each AgentTypeConfig is a annotated class type which can be used for annotation in other places.~~ - ~~Each AgentTypeConfig can be easily extended when we have more meta data needs.~~ - ~~Strong assertion to ensure AgentType and AGENT_TO_CLASS are always consistent.~~ - ~~Made AGENT_TO_CLASS automatically generated.~~ ~~Test Plan:~~ - ~~since this change is focusing on annotation, lint is the major test focus.~~ - ~~lint, format and test passed on local.~~	1 year ago

Rafal Wojdyla	160bfae93f	Add `DocstoreFn` - lookup doc via arbitrary function (#3760 ) This partially addresses https://github.com/hwchase17/langchain/issues/1524, but it's also useful for some of our use cases. This `DocstoreFn` allows to lookup a document given a function that accepts the `search` string without the need to implement a custom `Docstore`. This could be useful when: * you don't want to implement a `Docstore` just to provide a custom `search` * it's expensive to construct an `InMemoryDocstore`/dict * you retrieve documents from remote sources * you just want to reuse existing objects	1 year ago

Zander Chase	da7b51455c	Dynamic tool -> single purpose (#3697 ) I think the logic of https://github.com/hwchase17/langchain/pull/3684#pullrequestreview-1405358565 is too confusing. I prefer this alternative because: - All `Tool()` implementations by default will be treated the same as before. No breaking changes. - Less reliance on pydantic magic - The decorator (which only is typed as returning a callable) can infer schema and generate a structured tool - Either way, the recommended way to create a custom tool is through inheriting from the base tool	1 year ago
Zander Chase	4654c58f72	Add validation on agent instantiation for multi-input tools (#3681 ) Tradeoffs here: - No lint-time checking for compatibility - Differs from JS package - The signature inference, etc. in the base tool isn't simple - The `args_schema` is optional Pros: - Forwards compatibility retained - Doesn't break backwards compatibility - User doesn't have to think about which class to subclass (single base tool or dynamic `Tool` interface regardless of input) - No need to change the load_tools, etc. interfaces Co-authored-by: Hasan Patel <mangafield@gmail.com>	1 year ago
