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.
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.
Single edit to: models/text_embedding/examples/openai.ipynb - Line 88:
changed from: "embeddings = OpenAIEmbeddings(model_name=\"ada\")" to
"embeddings = OpenAIEmbeddings()" as model_name is no longer part of the
OpenAIEmbeddings class.
@vowelparrot @hwchase17 Here a new implementation of
`acompress_documents` for `LLMChainExtractor ` without changes to the
sync-version, as you suggested in #3587 / [Async Support for
LLMChainExtractor](https://github.com/hwchase17/langchain/pull/3587) .
I created a new PR to avoid cluttering history with reverted commits,
hope that is the right way.
Happy for any improvements/suggestions.
(PS:
I also tried an alternative implementation with a nested helper function
like
``` python
async def acompress_documents_old(
self, documents: Sequence[Document], query: str
) -> Sequence[Document]:
"""Compress page content of raw documents."""
async def _compress_concurrently(doc):
_input = self.get_input(query, doc)
output = await self.llm_chain.apredict_and_parse(**_input)
return Document(page_content=output, metadata=doc.metadata)
outputs=await asyncio.gather(*[_compress_concurrently(doc) for doc in documents])
compressed_docs=list(filter(lambda x: len(x.page_content)>0,outputs))
return compressed_docs
```
But in the end I found the commited version to be better readable and
more "canonical" - hope you agree.
Related to [this
issue.](https://github.com/hwchase17/langchain/issues/3655#issuecomment-1529415363)
The `Mapped` SQLAlchemy class is introduced in SQLAlchemy 1.4 but the
migration from 1.3 to 1.4 is quite challenging so, IMO, it's better to
keep backwards compatibility and not change the SQLAlchemy requirements
just because of type annotations.
This PR fixes the "SyntaxError: invalid escape sequence" error in the
pydantic.py file. The issue was caused by the backslashes in the regular
expression pattern being treated as escape characters. By using a raw
string literal for the regex pattern (e.g., r"\{.*\}"), this fix ensures
that backslashes are treated as literal characters, thus preventing the
error.

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

### Summary
Adds `UnstructuredAPIFileLoaders` and `UnstructuredAPIFIleIOLoaders`
that partition documents through the Unstructured API. Defaults to the
URL for hosted Unstructured API, but can switch to a self hosted or
locally running API using the `url` kwarg. Currently, the Unstructured
API is open and does not require an API, but it will soon. A note was
added about that to the Unstructured ecosystem page.
### Testing
```python
from langchain.document_loaders import UnstructuredAPIFileIOLoader
filename = "fake-email.eml"
with open(filename, "rb") as f:
loader = UnstructuredAPIFileIOLoader(file=f, file_filename=filename)
docs = loader.load()
docs[0]
```
```python
from langchain.document_loaders import UnstructuredAPIFileLoader
filename = "fake-email.eml"
loader = UnstructuredAPIFileLoader(file_path=filename, mode="elements")
docs = loader.load()
docs[0]
```
- 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()
```

Modified Modern Treasury and Strip slightly so credentials don't have to
be passed in explicitly. Thanks @mattgmarcus for adding Modern Treasury!
