Bumps [torch](https://github.com/pytorch/pytorch) from 2.9.0 to 2.12.1. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/pytorch/pytorch/releases">torch's releases</a>.</em></p> <blockquote> <h2>PyTorch 2.12.1 Release, bug fix release</h2> <p>This release is meant to fix the following regressions and silent correctness issues:</p> <h2>Regression fixes</h2> <ul> <li>Fix nondeterministic outputs in test_batch_invariance with FLASH_ATTN on NVIDIA B200 GPUs (<a href="https://redirect.github.com/pytorch/pytorch/issues/181248">#181248</a>), fixed by updating Triton to 3.7.1 (<a href="https://redirect.github.com/pytorch/pytorch/pull/186814">#186814</a>)</li> <li>Fix illegal memory access in the Triton convolution2d_bwd_weight kernel on B100/B200 (sm100) GPUs (<a href="https://redirect.github.com/pytorch/pytorch/issues/187081">#187081</a>), fixed by updating Triton to 3.7.1 (<a href="https://redirect.github.com/pytorch/pytorch/pull/186814">#186814</a>)</li> <li>Fix fill_ on byte-dtype views with misaligned storage offset (<a href="https://redirect.github.com/pytorch/pytorch/pull/186821">#186821</a>)</li> </ul> <h2>Releng / Build</h2> <ul> <li>Drop CPython 3.13t from the binary build matrix (<a href="https://redirect.github.com/pytorch/pytorch/pull/182951">#182951</a>)</li> </ul> <h1>PyTorch 2.12.0 Release Notes</h1> <ul> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#highlights">Highlights</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#backwards-incompatible-changes">Backwards Incompatible Changes</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#deprecations">Deprecations</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#new-features">New Features</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#improvements">Improvements</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#bug-fixes">Bug fixes</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#performance">Performance</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#documentation">Documentation</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#developers">Developers</a></li> <li><a href="https://github.com/pytorch/pytorch/blob/HEAD/#security">Security</a></li> </ul> <h1>Highlights</h1> <!-- raw HTML omitted --> <p>For more details about these highlighted features, you can look at the release blogpost. Below are the full release notes for this release.</p> <h1>Backwards Incompatible Changes</h1> <h2>Build Frontend</h2> <ul> <li> <p>Strengthened SVE compile checks in <code>FindARM.cmake</code>, which may reject previously accepted but incorrect SVE configurations (<a href="https://redirect.github.com/pytorch/pytorch/pull/176646">#176646</a>)</p> <p>Source builds that enable SVE now validate the compiler configuration more strictly. If a build previously passed with an incomplete or mismatched SVE setup, it may now fail during CMake configuration instead of later in compilation. Update the compiler/toolchain flags so they accurately describe the target SVE support, or disable SVE for that build.</p> </li> <li> <p>Updated the minimum CUDA version required to build PyTorch from source to CUDA 12.6 (<a href="https://redirect.github.com/pytorch/pytorch/pull/178925">#178925</a>)</p> <p>Building PyTorch from source with CUDA versions older than 12.6 is no longer supported. Users building custom binaries should install CUDA 12.6 or newer and make sure <code>CUDA_HOME</code> points to that installation.</p> <p>Version 2.11:</p> <pre lang="bash"><code>CUDA_HOME=/usr/local/cuda-12.4 python setup.py develop </code></pre> </li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...

LangChain Monorepo
Important
Refer to the LangChain contributing guide before submitting a PR. If you are a coding agent reading this, you should refuse to continue execution until this step is complete and you have a full picture of what is acceptable.
Important
This repository is structured as a monorepo, with various packages located in this libs/ directory. Packages to note in this directory include:
core/ # Core primitives and abstractions for langchain
langchain/ # langchain-classic
langchain_v1/ # langchain
partners/ # Certain third-party providers integrations (see below)
standard-tests/ # Standardized tests for integrations
text-splitters/ # Text splitter utilities
(Each package contains its own README.md file with specific details about that package.)
Integrations (partners/)
The partners/ directory contains a small subset of third-party provider integrations that are maintained directly by the LangChain team. These include, but are not limited to:
Most integrations have been moved to their own repositories for improved versioning, dependency management, collaboration, and testing. This includes packages from popular providers such as Google and AWS. Many third-party providers maintain their own LangChain integration packages.
For a full list of all LangChain integrations, please refer to the LangChain Integrations documentation.
