# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, caste, color, religion, or sexual
identity and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the overall
community
Examples of unacceptable behavior include:
* The use of sexualized language or imagery, and sexual attention or advances of
any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email address,
without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
conduct@langchain.dev.
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series of
actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or permanent
ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within the
community.

## 🚀 Quick Start
This quick start guide explains how to run the repository locally.
For a [development container](https://containers.dev/), see the [.devcontainer folder](https://github.com/langchain-ai/langchain/tree/master/.devcontainer).
> **Note:** You can run this repository locally (which is described below) or in a [development container](https://containers.dev/) (which is described in the [.devcontainer folder](https://github.com/hwchase17/langchain/tree/master/.devcontainer)).
### Dependency Management: Poetry and other env/dependency managers
This project uses [Poetry](https://python-poetry.org/) as a dependency manager. Check out Poetry's [documentation on how to install it](https://python-poetry.org/docs/#installation) on your system before proceeding.
This project utilizes [Poetry](https://python-poetry.org/) v1.6.1+ as a dependency manager.
❗Note: If you use `Conda` or `Pyenv` as your environment / package manager, avoid dependency conflicts by doing the following first:
1. *Before installing Poetry*, create and activate a new Conda env (e.g. `conda create -n langchain python=3.9`)
2. Install Poetry (see above)
3. Tell Poetry to use the virtualenv python environment (`poetry config virtualenvs.prefer-active-python true`)
4. Continue with the following steps.
❗Note: *Before installing Poetry*, if you use `Conda`, create and activate a new Conda env (e.g. `conda create -n langchain python=3.9`)
There are two separate projects in this repository:
- `langchain`: core langchain code, abstractions, and use cases
- `langchain.experimental`: more experimental code
Install Poetry: **[documentation on how to install it](https://python-poetry.org/docs/#installation)**.
Each of these has their OWN development environment.
In order to run any of the commands below, please move into their respective directories.
For example, to contribute to `langchain` run `cd libs/langchain` before getting started with the below.
❗Note: If you use `Conda` or `Pyenv` as your environment/package manager, after installing Poetry,
tell Poetry to use the virtualenv python environment (`poetry config virtualenvs.prefer-active-python true`)
### Core vs. Experimental
This repository contains two separate projects:
- `langchain`: core langchain code, abstractions, and use cases.
- `langchain.experimental`: see the [Experimental README](https://github.com/langchain-ai/langchain/tree/master/libs/experimental/README.md) for more information.
Each of these has its own development environment. Docs are run from the top-level makefile, but development
is split across separate test & release flows.
For this quickstart, start with langchain core:
To install requirements:
```bash
cd libs/langchain
poetry install -E all
```
### Local Development Dependencies
This will install all requirements for running the package, examples, linting, formatting, tests, and coverage. Note the `-E all` flag will install all optional dependencies necessary for integration testing.
Install langchain development requirements (for running langchain, running examples, linting, formatting, tests, and coverage):
❗Note: If you're running Poetry 1.4.1 and receive a `WheelFileValidationError` for `debugpy` during installation, you can try either downgrading to Poetry 1.4.0 or disabling "modern installation" (`poetry config installer.modern-installation false`) and re-install requirements. See [this `debugpy` issue](https://github.com/microsoft/debugpy/issues/1246) for more details.
Now, you should be able to run the common tasks in the following section. To double check, run `make test`, all tests should pass. If they don't you may need to pip install additional dependencies, such as `numexpr` and `openapi_schema_pydantic`.
## ✅ Common Tasks
Type `make` for a list of common tasks.
### Code Formatting
Formatting for this project is done via a combination of [Black](https://black.readthedocs.io/en/stable/) and [isort](https://pycqa.github.io/isort/).
To run formatting for this project:
```bash
poetry install --with test
```
Then verify dependency installation:
```bash
make test
```
If the tests don't pass, you may need to pip install additional dependencies, such as `numexpr` and `openapi_schema_pydantic`.
If during installation you receive a `WheelFileValidationError` for `debugpy`, please make sure you are running
Poetry v1.6.1+. This bug was present in older versions of Poetry (e.g. 1.4.1) and has been resolved in newer releases.
If you are still seeing this bug on v1.6.1, you may also try disabling "modern installation"
(`poetry config installer.modern-installation false`) and re-installing requirements.
See [this `debugpy` issue](https://github.com/microsoft/debugpy/issues/1246) for more details.
### Testing
_some test dependencies are optional; see section about optional dependencies_.
Unit tests cover modular logic that does not require calls to outside APIs.
If you add new logic, please add a unit test.
To run unit tests:
```bash
make test
```
To run unit tests in Docker:
```bash

## Working with Optional Dependencies
### Coverage
Code coverage (i.e. the amount of code that is covered by unit tests) helps identify areas of the code that are potentially more or less brittle.
To get a report of current coverage, run the following:
```bash
make coverage
```
### Working with Optional Dependencies
Langchain relies heavily on optional dependencies to keep the Langchain package lightweight.
If you're adding a new dependency to Langchain, assume that it will be an optional dependency, and
that most users won't have it installed.
Users who do not have the dependency installed should be able to **import** your code without
any side effects (no warnings, no errors, no exceptions).

## Adding a Jupyter Notebook
### Testing
If you are adding a Jupyter Notebook example, you'll want to install the optional `dev` dependencies.
See section about optional dependencies.
#### Unit Tests
Unit tests cover modular logic that does not require calls to outside APIs.
To run unit tests:
```bash
make test
```
To run unit tests in Docker:
```bash

```
If you add new logic, please add a unit test.
#### Integration Tests
Integration tests cover logic that requires making calls to outside APIs (often integration with other services).
**warning** Almost no tests should be integration tests.
Tests that require making network connections make it difficult for other
developers to test the code.
Instead favor relying on `responses` library and/or mock.patch to mock
requests using small fixtures.
To run integration tests:
```bash
make integration_tests

date that is similar to the date when the file was actually last modified,
assuming the actual modification date and its commit date are close.

# TODO:
# - Add -z on git whatchanged/ls-files, so we don't deal with filename decoding
# - When Python is bumped to 3.7, use text instead of universal_newlines on subprocess
# - Update "Statistics for some large projects" with modern hardware and repositories.
# - Create a README.md for git-restore-mtime alone. It deserves extensive documentation
# - Move Statistics there
# - See git-extras as a good example on project structure and documentation
# FIXME:
# - When current dir is outside the worktree, e.g. using --work-tree, `git ls-files`
# assume any relative pathspecs are to worktree root, not the current dir. As such,
# relative pathspecs may not work.
# - Renames are tricky:
# - R100 should not change mtime, but original name is not on filelist. Should
# track renames until a valid (A, M) mtime found and then set on current name.
# - Should set mtime for both current and original directories.
# - Check mode changes with unchanged blobs?
# - Check file (A, D) for the directory mtime is not sufficient:
# - Renames also change dir mtime, unless rename was on a parent dir
# - If most recent change of all files in a dir was a Modification (M),
# dir might not be touched at all.
# - Dirs containing only subdirectories but no direct files will also
# not be touched. They're files' [grand]parent dir, but never their dirname().
# - Some solutions:
# - After files done, perform some dir processing for missing dirs, finding latest
# file (A, D, R)
# - Simple approach: dir mtime is the most recent child (dir or file) mtime
# - Use a virtual concept of "created at most at" to fill missing info, bubble up
# to parents and grandparents
# - When handling [grand]parent dirs, stay inside <pathspec>
# - Better handling of merge commits. `-m` is plain *wrong*. `-c/--cc` is perfect, but
# painfully slow. First pass without merge commits is not accurate. Maybe add a new
# `--accurate` mode for `--cc`?

Git stores paths as UTF-8 normalization form C.
If path contains non-ASCII or non-printable characters, git outputs the UTF-8
in octal-escaped notation, escaping double-quotes and backslashes, and then
double-quoting the whole path.
https://git-scm.com/docs/git-config#Documentation/git-config.txt-corequotePath
This function reverts this encoding, so:
normalize(r'"Back\\slash_double\"quote_a\303\247a\303\255"') =>
r'Back\slash_double"quote_açaí')
Paths with invalid UTF-8 encoding, such as single 0x80-0xFF bytes (e.g, from
Latin1/Windows-1251 encoding) are decoded using surrogate escape, the same
method used by Python for filesystem paths. So 0xE6 ("æ" in Latin1, r'\\346'
from Git) is decoded as "\udce6". See https://peps.python.org/pep-0383/ and
https://vstinner.github.io/painful-history-python-filesystem-encoding.html
Also see notes on `windows/non-ascii-paths.txt` about path encodings on
non-UTF-8 platforms and filesystems.

# - That dependency used to be required, so it may have been cached.
# When restoring the venv packages from cache, that dependency gets included.

## 🚨Breaking Changes for select chains (SQLDatabase) on 7/28
In an effort to make `langchain` leaner and safer, we are moving select chains to `langchain_experimental`.
This migration has already started, but we are remaining backwards compatible until 7/28.
On that date, we will remove functionality from `langchain`.

"# How to use a SmartLLMChain\n",
"\n",
"A SmartLLMChain is a form of self-critique chain that can help you if have particularly complex questions to answer. Instead of doing a single LLM pass, it instead performs these 3 steps:\n",
"1. Ideation: Pass the user prompt n times through the LLM to get n output proposals (called \"ideas\"), where n is a parameter you can set \n",
"2. Critique: The LLM critiques all ideas to find possible flaws and picks the best one \n",
"3. Resolve: The LLM tries to improve upon the best idea (as chosen in the critique step) and outputs it. This is then the final output.\n",
"\n",
"SmartLLMChains are based on the SmartGPT workflow proposed in https://youtu.be/wVzuvf9D9BU.\n",
"\n",
"Note that SmartLLMChains\n",
"- use more LLM passes (ie n+2 instead of just 1)\n",
"- only work then the underlying LLM has the capability for reflection, which smaller models often don't\n",
"- only work with underlying models that return exactly 1 output, not multiple\n",

"A black hole is a region in space where gravity is extremely strong, so strong that nothing, not even light, can escape its gravitational pull. It is formed when a massive star collapses under its own gravity during a supernova explosion. The collapse causes an incredibly dense mass to be concentrated in a small volume, creating a gravitational field that is so intense that it warps space and time. Black holes have a boundary called the event horizon, which marks the point of no return for anything that gets too close. Beyond the event horizon, the gravitational pull is so strong that even light cannot escape, hence the name \"black hole.\" While we have a good understanding of black holes, there is still much to learn, especially about what happens inside them.\n"

"Thank you for your kind words! I will do my best to break down the concept of a path integral for you.\n",
"\n",
"In mathematics and physics, a path integral is a mathematical tool used to calculate the probability amplitude or wave function of a particle or system of particles. It was introduced by Richard Feynman and is an integral over all possible paths that a particle can take to go from an initial state to a final state.\n",
"\n",
"To understand the concept better, let's consider an example. Suppose we have a particle moving from point A to point B in space. Classically, we would describe this particle's motion using a definite trajectory, but in quantum mechanics, particles can simultaneously take multiple paths from A to B.\n",
"\n",
"The path integral formalism considers all possible paths that the particle could take and assigns a probability amplitude to each path. These probability amplitudes are then added up, taking into account the interference effects between different paths.\n",
"\n",
"To calculate a path integral, we need to define an action, which is a mathematical function that describes the behavior of the system. The action is usually expressed in terms of the particle's position, velocity, and time.\n",
"\n",
"Once we have the action, we can write down the path integral as an integral over all possible paths. Each path is weighted by a factor determined by the action and the principle of least action, which states that a particle takes a path that minimizes the action.\n",
"\n",
"Mathematically, the path integral is expressed as:\n",
"\n",
"∫ e^(iS/ħ) D[x(t)]\n",
"\n",
"Here, S is the action, ħ is the reduced Planck's constant, and D[x(t)] represents the integration over all possible paths x(t) of the particle.\n",
"\n",
"By evaluating this integral, we can obtain the probability amplitude for the particle to go from the initial state to the final state. The absolute square of this amplitude gives us the probability of finding the particle in a particular state.\n",
"\n",
"Path integrals have proven to be a powerful tool in various areas of physics, including quantum mechanics, quantum field theory, and statistical mechanics. They allow us to study complex systems and calculate probabilities that are difficult to obtain using other methods.\n",
"\n",
"I hope this explanation helps you understand the concept of a path integral. If you have any further questions, feel free to ask!\n"

# Cookbook
import DocCardList from "@theme/DocCardList";
Example code for accomplishing common tasks with the LangChain Expression Language (LCEL). These examples show how to compose different Runnable (the core LCEL interface) components to achieve various tasks. If you're just getting acquainted with LCEL, the [Prompt + LLM](/docs/expression_language/cookbook/prompt_llm_parser) page is a good place to start.

"'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.'"

Some examples of interactions:\\n\\n- Ask general knowledge questions and LangChain will try to answer factually. For example \"What is the capital of France?\"\\n\\n- Have conversations on topics by taking turns speaking. You can prompt the start of a conversation by saying something like \"Let\\'s discuss machine learning\"\\n\\n- Ask for summaries or high-level explanations on subjects. For example \"Can you summarize the main themes in Shakespeare\\'s Hamlet?\" \\n\\n- Give creative writing prompts or requests to have LangChain generate text in different styles. For example \"Write a short children\\'s story about a mouse\" or \"Generate a poem in the style of Robert Frost about nature\"\\n\\n- Correct LangChain if it makes an inaccurate statement and provide the right information.

# LangChain Expression Language (LCEL)
LangChain Expression Language or LCEL is a declarative way to easily compose chains together.
There are several benefits to writing chains in this manner (as opposed to writing normal code):
**Async, Batch, and Streaming Support**
Any chain constructed this way will automatically have full sync, async, batch, and streaming support.
This makes it easy to prototype a chain in a Jupyter notebook using the sync interface, and then expose it as an async streaming interface.
**Fallbacks**
The non-determinism of LLMs makes it important to be able to handle errors gracefully.
With LCEL you can easily attach fallbacks to any chain.
**Parallelism**
Since LLM applications involve (sometimes long) API calls, it often becomes important to run things in parallel.
With LCEL syntax, any components that can be run in parallel automatically are.
**Seamless LangSmith Tracing Integration**
As your chains get more and more complex, it becomes increasingly important to understand what exactly is happening at every step.
With LCEL, **all** steps are automatically logged to [LangSmith](https://smith.langchain.com) for maximal observability and debuggability.

# Why use LCEL?
The LangChain Expression Language was designed from day 1 to **support putting prototypes in production, with no code changes**, from the simplest “prompt + LLM” chain to the most complex chains (weve seen folks successfully running in production LCEL chains with 100s of steps). To highlight a few of the reasons you might want to use LCEL:
- first-class support for streaming: when you build your chains with LCEL you get the best possible time-to-first-token (time elapsed until the first chunk of output comes out). For some chains this means eg. we stream tokens straight from an LLM to a streaming output parser, and you get back parsed, incremental chunks of output at the same rate as the LLM provider outputs the raw tokens. Were constantly improving streaming support, recently we added a [streaming JSON parser](https://twitter.com/LangChainAI/status/1709690468030914584), and more is in the works.
- first-class async support: any chain built with LCEL can be called both with the synchronous API (eg. in your Jupyter notebook while prototyping) as well as with the asynchronous API (eg. in a [LangServe](https://github.com/langchain-ai/langserve) server). This enables using the same code for prototypes and in production, with great performance, and the ability to handle many concurrent requests in the same server.
- optimised parallel execution: whenever your LCEL chains have steps that can be executed in parallel (eg if you fetch documents from multiple retrievers) we automatically do it, both in the sync and the async interfaces, for the smallest possible latency.
- support for retries and fallbacks: more recently weve added support for configuring retries and fallbacks for any part of your LCEL chain. This is a great way to make your chains more reliable at scale. Were currently working on adding streaming support for retries/fallbacks, so you can get the added reliability without any latency cost.
- accessing intermediate results: for more complex chains its often very useful to access the results of intermediate steps even before the final output is produced. This can be used let end-users know something is happening, or even just to debug your chain. Weve added support for [streaming intermediate results](https://x.com/LangChainAI/status/1711806009097044193?s=20), and its available on every LangServe server.
- [input and output schemas](https://x.com/LangChainAI/status/1711805322195861934?s=20): input and output schemas give every LCEL chain Pydantic and JSONSchema schemas inferred from the structure of your chain. This can be used for validation of inputs and outputs, and is an integral part of LangServe.
- tracing with LangSmith: all chains built with LCEL have first-class tracing support, which can be used to debug your chains, or to understand whats happening in production. To enable this all you have to do is add your [LangSmith](https://www.langchain.com/langsmith) API key as an environment variable.

"# Fallbacks\n",
"\n",
"When working with language models, you may often encounter issues from the underlying APIs, whether these be rate limiting or downtime. Therefore, as you go to move your LLM applications into production it becomes more and more important to safeguard against these. That's why we've introduced the concept of fallbacks. \n",

"A **fallback** is an alternative plan that may be used in an emergency.\n",
"\n",
"Crucially, fallbacks can be applied not only on the LLM level but on the whole runnable level. This is important because often times different models require different prompts. So if your call to OpenAI fails, you don't just want to send the same prompt to Anthropic - you probably want to use a different prompt template and send a different version there."
