Anirudh Suresh	03ac39368f	Fixing DeepLake Overwrite Flag (#4683 ) # Fix DeepLake Overwrite Flag Issue Fixes Issue #4682: essentially, setting overwrite to False in the DeepLake constructor still triggers an overwrite, because the logic is just checking for the presence of "overwrite" in kwargs. The fix is simple--just add some checks to inspect if "overwrite" in kwargs AND kwargs["overwrite"]==True. Added a new test in tests/integration_tests/vectorstores/test_deeplake.py to reflect the desired behavior.

Evan Jones	f668251948	parameterized distance metrics; lint; format; tests (#4375 ) # Parameterize Redis vectorstore index Redis vectorstore allows for three different distance metrics: `L2` (flat L2), `COSINE`, and `IP` (inner product). Currently, the `Redis._create_index` method hard codes the distance metric to COSINE. I've parameterized this as an argument in the `Redis.from_texts` method -- pretty simple. Fixes #4368 ## Before submitting I've added an integration test showing indexes can be instantiated with all three values in the `REDIS_DISTANCE_METRICS` literal. An example notebook seemed overkill here. Normal API documentation would be more appropriate, but no standards are in place for that yet. ## Who can review? Not sure who's responsible for the vectorstore module... Maybe @eyurtsev / @hwchase17 / @agola11 ?	1 year ago

Eugene Yurtsev	2ceb807da2	Add PDF parser implementations (#4356 ) # Add PDF parser implementations This PR separates the data loading from the parsing for a number of existing PDF loaders. Parser tests have been designed to help encourage developers to create a consistent interface for parsing PDFs. This interface can be made more consistent in the future by adding information into the initializer on desired behavior with respect to splitting by page etc. This code is expected to be backwards compatible -- with the exception of a bug fix with pymupdf parser which was returning `bytes` in the page content rather than strings. Also changing the lazy parser method of document loader to return an Iterator rather than Iterable over documents. ## Before submitting <!-- If you're adding a new integration, include an integration test and an example notebook showing its use! --> ## Who can review?

Mike Wang	c3044b1bf0	[test] Add integration_test for PandasAgent (#4056 ) - confirm creation - confirm functionality with a simple dimension check. The test now is calling OpenAI API directly, but learning from @vowelparrot that we’re caching the requests, so that it’s not that expensive. I also found we’re calling OpenAI api in other integration tests. Please lmk if there is any concern of real external API calls. I can alternatively make a fake LLM for this test. Thanks	1 year ago

Jon Saginaw	ea64b1716d	Enhancement: option to Get All Tokens with a single Blockchain Document Loader call (#3797 ) The Blockchain Document Loader's default behavior is to return 100 tokens at a time which is the Alchemy API limit. The Document Loader exposes a startToken that can be used for pagination against the API. This enhancement includes an optional get_all_tokens param (default: False) which will: - Iterate over the Alchemy API until it receives all the tokens, and return the tokens in a single call to the loader. - Manage all/most tokenId formats (this can be int, hex16 with zero or all the leading zeros). There aren't constraints as to how smart contracts can represent this value, but these three are most common. Note that a contract with 10,000 tokens will issue 100 calls to the Alchemy API, and could take about a minute, which is why this param will default to False. But I've been using the doc loader with these utilities on the side, so figured it might make sense to build them in for others to use.	1 year ago

Mike Wang	ec21b7126c	[agent][property type] Change allowed_tools to Set as Duplicate doesn’t make sense (#3840 ) - ActionAgent has a property called, `allowed_tools`, which is declared as `List`. It stores all provided tools which is available to use during agent action. - This collection shouldn’t allow duplicates. The original datatype List doesn’t make sense. Each tool should be unique. Even when there are variants (assuming in the future), it would be named differently in load_tools. Test: - confirm the functionality in an example by initializing an agent with a list of 2 tools and confirm everything works. ```python3 def test_agent_chain_chat_bot(): from langchain.agents import load_tools from langchain.agents import initialize_agent from langchain.agents import AgentType from langchain.chat_models import ChatOpenAI from langchain.llms import OpenAI from langchain.utilities.duckduckgo_search import DuckDuckGoSearchAPIWrapper chat = ChatOpenAI(temperature=0) llm = OpenAI(temperature=0) tools = load_tools(["ddg-search", "llm-math"], llm=llm) agent = initialize_agent(tools, chat, agent=AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION, verbose=True) agent.run("Who is Olivia Wilde's boyfriend?
