bump 298 (#10892)

**Description:**
This commit adds a vector store for the Postgres-based vector database
(`TimescaleVector`).

Timescale Vector(https://www.timescale.com/ai) is PostgreSQL++ for AI
applications. It enables you to efficiently store and query billions of
vector embeddings in `PostgreSQL`:
- Enhances `pgvector` with faster and more accurate similarity search on
1B+ vectors via DiskANN inspired indexing algorithm.
- Enables fast time-based vector search via automatic time-based
partitioning and indexing.
- Provides a familiar SQL interface for querying vector embeddings and
relational data.

Timescale Vector scales with you from POC to production:
- Simplifies operations by enabling you to store relational metadata,
vector embeddings, and time-series data in a single database.
- Benefits from rock-solid PostgreSQL foundation with enterprise-grade
feature liked streaming backups and replication, high-availability and
row-level security.
- Enables a worry-free experience with enterprise-grade security and
compliance.

Timescale Vector is available on Timescale, the cloud PostgreSQL
platform. (There is no self-hosted version at this time.) LangChain
users get a 90-day free trial for Timescale Vector.

 # Introduction
 
-**LangChain** is a framework for developing applications powered by language models. It enables applications that are:
-- **Data-aware**: connect a language model to other sources of data
-- **Agentic**: allow a language model to interact with its environment
+**LangChain** is a framework for developing applications powered by language models. It enables applications that:
+- **Are context-aware**: connect a language model to sources of context (prompt instructions, few shot examples, content to ground its response in, etc.)
+- **Reason**: rely on a language model to reason (about how to answer based on provided context, what actions to take, etc.)
 
 The main value props of LangChain are:
 1. **Components**: abstractions for working with language models, along with a collection of implementations for each abstraction. Components are modular and easy-to-use, whether you are using the rest of the LangChain framework or not
 2. **Off-the-shelf chains**: a structured assembly of components for accomplishing specific higher-level tasks
 
-Off-the-shelf chains make it easy to get started. For more complex applications and nuanced use-cases, components make it easy to customize existing chains or build new ones.

 Now we can start building our language model application. LangChain provides many modules that can be used to build language model applications.
 Modules can be used as stand-alones in simple applications and they can be combined for more complex use cases.
 
-The core building block of LangChain applications is the LLMChain.
-This combines three things:
+The most common and most important chain that LangChain helps create contains three things:
 - LLM: The language model is the core reasoning engine here. In order to work with LangChain, you need to understand the different types of language models and how to work with them.
 - Prompt Templates: This provides instructions to the language model. This controls what the language model outputs, so understanding how to construct prompts and different prompting strategies is crucial.
 - Output Parsers: These translate the raw response from the LLM to a more workable format, making it easy to use the output downstream.
 
-In this getting started guide we will cover those three components by themselves, and then cover the LLMChain which combines all of them.

@@ -7,20 +7,27 @@ The core idea of agents is to use an LLM to choose a sequence of actions to take
 In chains, a sequence of actions is hardcoded (in code).
 In agents, a language model is used as a reasoning engine to determine which actions to take and in which order.
 
+Some important terminology (and schema) to know:
+
+1. `AgentAction`: This is a dataclass that represents the action an agent should take. It has a `tool` property (which is the tool that should be invoked) and a `tool_input` property (the input to that tool)
+2. `AgentFinish`: This is a dataclass that signifies that the agent has finished and should return to the user. It has a `return_values` parameter, which is a dictionary to return. It often only has one key - `output` - that is a string, and so often it is just this key that is returned.
+3. `intermediate_steps`: These represent previous agent actions and corresponding outputs that are passed around. These are important to pass to future iteration so the agent knows what work it has already done. This is typed as a `List[Tuple[AgentAction, Any]]`. Note that observation is currently left as type `Any` to be maximally flexible. In practice, this is often a string.
+
 There are several key components here:
 
 ## Agent
 
-This is the class responsible for deciding what step to take next.
+This is the chain responsible for deciding what step to take next.
 This is powered by a language model and a prompt.
-This prompt can include things like:
+The inputs to this chain are:
 
-1. The personality of the agent (useful for having it respond in a certain way)
-2. Background context for the agent (useful for giving it more context on the types of tasks it's being asked to do)
-3. Prompting strategies to invoke better reasoning (the most famous/widely used being [ReAct](https://arxiv.org/abs/2210.03629))
+1. List of available tools
+2. User input
+3. Any previously executed steps (`intermediate_steps`)
 
-LangChain provides a few different types of agents to get started.
-Even then, you will likely want to customize those agents with parts (1) and (2).
+This chain then returns either the next action to take or the final response to send to the user (`AgentAction` or `AgentFinish`).
+
+Different agents have different prompting styles for reasoning, different ways of encoding input, and different ways of parsing the output.

+       "'While Scrum has its potential cons and challenges, many organizations have successfully embraced and implemented this project management framework to great effect. The cons mentioned above can be mitigated or overcome with proper training, support, and a commitment to continuous improvement. It is also important to note that not all cons may be applicable to every organization or project.\\n\\nFor example, while Scrum may be complex initially, with proper training and guidance, teams can quickly grasp the concepts and practices. The lack of predictability can be mitigated by implementing techniques such as velocity tracking and release planning. The limited documentation can be addressed by maintaining a balance between lightweight documentation and clear communication among team members. The dependency on team collaboration can be improved through effective communication channels and regular team-building activities.\\n\\nScrum can be scaled and adapted to larger projects by using frameworks like Scrum of Scrums or LeSS (Large Scale Scrum). Concerns about speed versus quality can be addressed by incorporating quality assurance practices, such as continuous integration and automated testing, into the Scrum process. Scope creep can be managed by having a well-defined and prioritized product backlog, and a strong product owner can be developed through training and mentorship.\\n\\nResistance to change can be overcome by providing proper education and communication to stakeholders and involving them in the decision-making process. Ultimately, the cons of Scrum can be seen as opportunities for growth and improvement, and with the right mindset and support, they can be effectively managed.\\n\\nIn conclusion, while Scrum may have its challenges and potential cons, the benefits and advantages it offers in terms of collaboration, flexibility, adaptability, transparency, and customer satisfaction make it a widely adopted and successful project management framework. With proper implementation and continuous improvement, organizations can leverage Scrum to drive innovation, efficiency, and project success.'"

Different languages may have varying formats for personal identifiers. For example, the structure of names, locations and dates can differ greatly between languages and regions.

+
+Make sure to pass the callback handler to the `run` method so that all related chains and llm calls are correctly tracked.
+
+It is also recommended to pass `agent_name` in the metadata to be able to distinguish between agents in the dashboard.
+
+Example:
+
+```python

In essence, the theory posits that the universe began as an infinitely hot and dense point, known as a singularity, around 13.8 billion years ago. This singularity expanded rapidly, and as it did, it cooled and formed subatomic particles, which eventually coalesced into the first atoms, and later into the stars and galaxies we see today.\\n\\nThe theory gets its name from the idea that the universe began in a state of incredibly high energy and temperature, and has been expanding and cooling ever since. This expansion is thought to have been driven by a mysterious force known as dark energy, which is thought to be responsible for the accelerating expansion of the universe.\\n\\nOne of the key predictions of the Big Bang Theory is that the universe should be homogeneous and isotropic on large scales, meaning that it should look the same in all directions and have the same properties everywhere. This prediction has been confirmed by a wealth of observational evidence, including the cosmic microwave background radiation, which is thought to be a remnant of the early universe.\\n\\nOverall, the Big Bang Theory is a well-established and widely accepted explanation for the origins of the universe, and it has been supported by a vast amount of observational evidence from many fields of science.\", additional_kwargs={}, example=False)"

-# Chat loaders
-
-Like document loaders, chat loaders are utilities designed to help load conversations from popular communication platforms such as Facebook, Slack, Discord, etc. These are loaded into memory as LangChain chat message objects. Such utilities facilitate tasks such as fine-tuning a language model to match your personal style or voice. 
-
-This brief guide will illustrate the process using [OpenAI's fine-tuning API](https://platform.openai.com/docs/guides/fine-tuning) comprised of six steps:
-
-1. Export your Facebook Messenger chat data in a compatible format for your intended chat loader.
-2. Load the chat data into memory as LangChain chat message objects. (_this is what is covered in each integration notebook in this section of the documentation_).
-    - Assign a person to the "AI" role and optionally filter, group, and merge messages.
-3. Export these acquired messages in a format expected by the fine-tuning API.
-4. Upload this data to OpenAI.
-5. Fine-tune your model.
-6. Implement the fine-tuned model in LangChain.
-
-This guide is not wholly comprehensive but is designed to take you through the fundamentals of going from raw data to fine-tuned model.
-
-We will demonstrate the procedure through an example of fine-tuning a `gpt-3.5-turbo` model on Facebook Messenger data. 
-
-### 1. Export your chat data
-
-To export your Facebook messenger data, you can follow the [instructions here](https://www.zapptales.com/en/download-facebook-messenger-chat-history-how-to/). 
-
-:::important JSON format
-You must select "JSON format" (instead of HTML) when exporting your data to be compatible with the current loader.
-:::
-
-OpenAI requires at least 10 examples to fine-tune your model, but they recommend between 50-100 for more optimal results.
-You can use the example data stored at [this google drive link](https://drive.google.com/file/d/1rh1s1o2i7B-Sk1v9o8KNgivLVGwJ-osV/view?usp=sharing) to test the process.
-
-### 2. Load the chat
-
-Once you've obtained your chat data, you can load it into memory as LangChain chat message objects. Here’s an example of loading data using the Python code:
-
-```python
-from langchain.chat_loaders.facebook_messenger import FolderFacebookMessengerChatLoader
-
-loader = FolderFacebookMessengerChatLoader(
-    path="./facebook_messenger_chats",
-)
-
-chat_sessions = loader.load()
-```
-
-In this snippet, we point the loader to a directory of Facebook chat dumps which are then loaded as multiple "sessions" of messages, one session per conversation file.
-
-Once you've loaded the messages, you should decide which person you want to fine-tune the model to (usually yourself). You can also decide to merge consecutive messages from the same sender into a single chat message.
-For both of these tasks, you can use the chat_loaders utilities to do so:
-
-```
-from langchain.chat_loaders.utils import (
-    merge_chat_runs,
-    map_ai_messages,
-)
-
-merged_sessions = merge_chat_runs(chat_sessions)
-alternating_sessions = list(map_ai_messages(merged_sessions, "My Name"))
-```
-
-### 3. Export messages to OpenAI format
-
-Convert the chat messages to dictionaries using the `convert_messages_for_finetuning` function. Then, group the data into chunks for better context modeling and overlap management.
-
-```python
-from langchain.adapters.openai import convert_messages_for_finetuning
-
-openai_messages = convert_messages_for_finetuning(chat_sessions)
-```
-
-At this point, the data is ready for upload to OpenAI. You can choose to split up conversations into smaller chunks for training if you
-do not have enough conversations to train on. Feel free to play around with different chunk sizes or with adding system messages to the fine-tuning data.
-
-```python
-chunk_size = 8
-overlap = 2
-
-message_groups = [
-    conversation_messages[i: i + chunk_size] 
-    for conversation_messages in openai_messages
-    for i in range(
-        0, len(conversation_messages) - chunk_size + 1, 
-        chunk_size - overlap)
-]
-
-len(message_groups)
-# 9
-```
-
-### 4. Upload the data to OpenAI
-
-Ensure you have set your OpenAI API key by following these [instructions](https://platform.openai.com/account/api-keys), then upload the training file.
-An audit is performed to ensure data compliance, so you may have to wait a few minutes for the dataset to become ready for use.
-
-```python
-import time
-import json
-import io
-
-import openai
-
-my_file = io.BytesIO()
-for group in message_groups:
-    my_file.write((json.dumps({"messages": group}) + "\n").encode('utf-8'))
-
-my_file.seek(0)
-training_file = openai.File.create(
-  file=my_file,
-  purpose='fine-tune'
-)
-
-# Wait while the file is processed
-status = openai.File.retrieve(training_file.id).status
-start_time = time.time()
-while status != "processed":
-    print(f"Status=[{status}]... {time.time() - start_time:.2f}s", end="\r", flush=True)
-    time.sleep(5)
-    status = openai.File.retrieve(training_file.id).status
-print(f"File {training_file.id} ready after {time.time() - start_time:.2f} seconds.")
-```
-
-Once this is done, you can proceed to the model training!
-
-### 5. Fine-tune the model
-
-Start the fine-tuning job with your chosen base model.
-
-```python
-job = openai.FineTuningJob.create(
-    training_file=training_file.id,
-    model="gpt-3.5-turbo",
-)
-```
-
-This might take a while. Check the status with `openai.FineTuningJob.retrieve(job.id).status` and wait for it to report `succeeded`.
-
-```python
-# It may take 10-20+ minutes to complete training.
-status = openai.FineTuningJob.retrieve(job.id).status
-start_time = time.time()
-while status != "succeeded":
-    print(f"Status=[{status}]... {time.time() - start_time:.2f}s", end="\r", flush=True)
-    time.sleep(5)
-    job = openai.FineTuningJob.retrieve(job.id)
-    status = job.status
-```
-
-### 6. Use the model in LangChain
-
-You're almost there! Use the fine-tuned model in LangChain.
-
-```python
-from langchain import chat_models
-
-model_name = job.fine_tuned_model
-# Example: ft:gpt-3.5-turbo-0613:personal::5mty86jblapsed
-model = chat_models.ChatOpenAI(model=model_name)
-```
-
-```python
-from langchain.prompts import ChatPromptTemplate
-from langchain.schema.output_parser import StrOutputParser 
-
-prompt = ChatPromptTemplate.from_messages(
-    [
-        ("human", "{input}"),
-    ]
-)
-
-chain = prompt | model | StrOutputParser()
-
-for tok in chain.stream({"input": "What classes are you taking?"}):
-    print(tok, end="", flush=True)
-
-# The usual - Potions, Transfiguration, Defense Against the Dark Arts. What about you?
-```
-
-And that's it! You've successfully fine-tuned a model and used it in LangChain.
-
-## Supported Chat Loaders
-
-LangChain currently supports the following chat loaders. Feel free to contribute more!
