added Wikipedia retriever (#4302)
- added `Wikipedia` retriever. It is effectively a wrapper for
`WikipediaAPIWrapper`. It wrapps load() into get_relevant_documents()
- sorted `__all__` in the `retrievers/__init__`
- added integration tests for the WikipediaRetriever
- added an example (as Jupyter notebook) for the WikipediaRetriever

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! -->

Update qdrant interface (#3971)
Hello

1) Passing `embedding_function` as a callable seems to be outdated and
the common interface is to pass `Embeddings` instance

2) At the moment `Qdrant.add_texts` is designed to be used with
`embeddings.embed_query`, which is 1) slow 2) causes ambiguity due to 1.
It should be used with `embeddings.embed_documents`

This PR solves both problems and also provides some new tests

[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

JSON loader (#4067)
This implements a loader of text passages in JSON format. The `jq`
syntax is used to define a schema for accessing the relevant contents
from the JSON file. This requires dependency on the `jq` package:

Update WhatsAppChatLoader regex to handle multiple date-time formats (#4186)
This PR updates the `message_line_regex` used by `WhatsAppChatLoader` to
support different date-time formats used in WhatsApp chat exports;
resolves #4153.

The new regex handles the following input formats:
```terminal
[05.05.23, 15:48:11] James: Hi here
[11/8/21, 9:41:32 AM] User name: Message 123
1/23/23, 3:19 AM - User 2: Bye!
1/23/23, 3:22_AM - User 1: And let me know if anything changes
```

Tests have been added to verify that the loader works correctly with all
formats.

Refactor TelegramChatLoader and FacebookChatLoader classes and add tests (#3863)
This PR includes two main changes:

- Refactor the `TelegramChatLoader` and `FacebookChatLoader` classes by
removing the dependency on pandas and simplifying the message filtering
process.

- Add test cases for the `TelegramChatLoader` and `FacebookChatLoader`
classes. This test ensures that the class correctly loads and processes
the example chat data, providing better test coverage for this
functionality.

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.

[Breaking] Migrate GPT4All to use PyGPT4All (#3934)
Seems the pyllamacpp package is no longer the supported bindings from
gpt4all. Tested that this works locally.

Given that the older models weren't very performant, I think it's better
to migrate now without trying to include a lot of try / except blocks

[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? What is his current age raised to the 0.23 power?")
test_agent_chain_chat_bot()
```

Add ChatModel, LLM, and Embeddings for Google's PaLM APIs (#3575)
- Add langchain.llms.GooglePalm for text completion,
 - Add langchain.chat_models.ChatGooglePalm for chat completion,
- Add langchain.embeddings.GooglePalmEmbeddings for sentence embeddings,
- Add example field to HumanMessage and AIMessage so that users can feed
in examples into the PaLM Chat API,
 - Add system and unit tests.

Note async completion for the Text API is not yet supported and will be
included in a future PR.

Happy for feedback on any aspect of this PR, especially our choice of
adding an example field to Human and AI Message objects to enable
passing example messages to the API.

Enhancement: Blockchain Document Loader with better Metadata support (#3710)
This PR includes some minor alignment updates, including:

- metadata object extended to support contractAddress, blockchainType,
and tokenId
- notebook doc better aligned to standard langchain format
- startToken changed from int to str to support multiple hex value types
on the Alchemy API

The updated metadata will look like the below. It's possible for a
single contractAddress to exist across multiple blockchains (e.g.
Ethereum, Polygon, etc.) so it's important to include the
blockchainType.

```
 metadata = {"source": self.contract_address, 
                      "blockchain": self.blockchainType,
                      "tokenId": tokenId}

Fix/issue 2695 (#3608)
## Background
fixes #2695  

## Changes
The `add_text` method uses the internal embedding function if one was
passes to the `Weaviate` constructor.
NOTE: the latest merge on the `Weaviate` class made the specification of
a `weaviate_api_key` mandatory which might not be desirable for all
users and connection methods (for example weaviate also support Embedded
Weaviate which I am happy to add support to here if people think it's
desirable). I wrapped the fetching of the api key into a try catch in
order to allow the `weaviate_api_key` to be unspecified. Do let me know
if this is unsatisfactory.

## Test Plan
added test for `add_texts` method.
