What is Transformer Engine?
===========================
.. overview-begin-marker-do-not-remove

Transformer Engine (TE) is a library for accelerating Transformer models on NVIDIA GPUs, including
using 8-bit floating point (FP8) precision on Hopper, Ada, and Blackwell GPUs, to provide better
performance with lower memory utilization in both training and inference. TE provides a collection
of highly optimized building blocks for popular Transformer architectures and an automatic mixed
precision-like API that can be used seamlessly with your framework-specific code. TE also includes a
framework agnostic C++ API that can be integrated with other deep learning libraries to enable FP8
support for Transformers.

As the number of parameters in Transformer models continues to grow, training and inference for
architectures such as BERT, GPT and T5 become very memory and compute-intensive. Most deep learning
frameworks train with FP32 by default. This is not essential, however, to achieve full accuracy for
many deep learning models. Using mixed-precision training, which combines single-precision (FP32)
with lower precision (e.g. FP16) format when training a model, results in significant speedups with
minimal differences in accuracy as compared to FP32 training. With Hopper GPU
architecture FP8 precision was introduced, which offers improved performance over FP16 with no
degradation in accuracy. Although all major deep learning frameworks support FP16, FP8 support is
not available natively in frameworks today.

TE addresses the problem of FP8 support by providing APIs that integrate with popular Large Language
Model (LLM) libraries. It provides a Python API consisting of modules to easily build a Transformer
layer as well as a framework-agnostic library in C++ including structs and kernels needed for FP8
support. Modules provided by TE internally maintain scaling factors and other values needed for FP8
training, greatly simplifying mixed precision training for users.

Highlights
==========

* Easy-to-use modules for building Transformer layers with FP8 support
* Optimizations (e.g. fused kernels) for Transformer models
* Support for FP8 on NVIDIA Hopper, Ada, and Blackwell GPUs
* Support for optimizations across all precisions (FP16, BF16) on NVIDIA Ampere GPU architecture generations and later

Installation Methods
^^^^^^^^^^^^^^^^^^^^

Docker (Recommended)
^^^^^^^^^^^^^^^^^^^^
The quickest way to get started with Transformer Engine is by using Docker images on
`NVIDIA GPU Cloud (NGC) Catalog <https://catalog.ngc.nvidia.com/orgs/nvidia/containers/pytorch>`_.


For example to use the NGC PyTorch container interactively,

.. code-block:: bash

    docker run --gpus all -it --rm nvcr.io/nvidia/pytorch:26.01-py3

For example to use the NGC JAX container interactively,

.. code-block:: bash

    docker run --gpus all -it --rm nvcr.io/nvidia/jax:26.01-py3

Where 26.01 (corresponding to January 2026 release) is the container version.

We recommend updating to the latest NGC container available here:

* https://catalog.ngc.nvidia.com/orgs/nvidia/containers/pytorch
* https://catalog.ngc.nvidia.com/orgs/nvidia/containers/jax

If you run any examples, please ensure you are using a matching version of TransformerEngine. TransformerEngine is pre-built and packaged inside the containers with examples available at ``/opt/transformerengine`` or ``/opt/transformer-engine``. If you would like to use examples from TE main branch and are running into import errors, please try the latest pip package or building from source, although NGC containers are recommended for ease-of-use for most users.

**Benefits of using NGC containers:**

* All dependencies pre-installed with compatible versions and optimized configurations
* NGC PyTorch 23.08+ containers include FlashAttention-2

pip Installation
^^^^^^^^^^^^^^^^

**Prerequisites for pip installation:**

* A compatible C++ compiler
* CUDA Toolkit with cuDNN and NVCC (NVIDIA CUDA Compiler) if installing from source.

To install the latest stable version with pip:

.. code-block:: bash

    # For PyTorch integration
    pip install --no-build-isolation transformer_engine[pytorch]
    
    # For JAX integration
    pip install --no-build-isolation transformer_engine[jax]
    
    # For both frameworks
    pip install --no-build-isolation transformer_engine[pytorch,jax]

Alternatively, install directly from the GitHub repository:

.. code-block:: bash

    pip install --no-build-isolation git+https://github.com/NVIDIA/TransformerEngine.git@stable

When installing from GitHub, you can explicitly specify frameworks using the environment variable:

.. code-block:: bash

    NVTE_FRAMEWORK=pytorch,jax pip install --no-build-isolation git+https://github.com/NVIDIA/TransformerEngine.git@stable

conda Installation
^^^^^^^^^^^^^^^^^^

To install the latest stable version with conda from conda-forge:

.. code-block:: bash

    # For PyTorch integration
    conda install -c conda-forge transformer-engine-torch
    
    # JAX integration (coming soon)

Source Installation
^^^^^^^^^^^^^^^^^^^

`See the installation guide <https://docs.nvidia.com/deeplearning/transformer-engine/user-guide/installation.html#installation-from-source>`_

Environment Variables
^^^^^^^^^^^^^^^^^^^^^
These environment variables can be set before installation to customize the build process:

* **CUDA_PATH**: Path to CUDA installation
* **CUDNN_PATH**: Path to cuDNN installation
* **CXX**: Path to C++ compiler
* **NVTE_FRAMEWORK**: Comma-separated list of frameworks to build for (e.g., ``pytorch,jax``)
* **MAX_JOBS**: Limit number of parallel build jobs (default varies by system)
* **NVTE_BUILD_THREADS_PER_JOB**: Control threads per build job
* **NVTE_CUDA_ARCHS**: Semicolon-separated list of CUDA compute architectures to compile for (e.g., ``80;90`` for A100 and H100). If not set, automatically determined based on CUDA version. Setting this can significantly reduce build time and binary size.

Compiling with FlashAttention
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Transformer Engine supports both FlashAttention-2 and FlashAttention-3 in PyTorch for improved performance. FlashAttention-3 was added in release v1.11 and is prioritized over FlashAttention-2 when both are present in the environment.

You can verify which FlashAttention version is being used by setting these environment variables:

.. code-block:: bash

    NVTE_DEBUG=1 NVTE_DEBUG_LEVEL=1 python your_script.py

It is a known issue that FlashAttention-2 compilation is resource-intensive and requires a large amount of RAM (see `bug <https://github.com/Dao-AILab/flash-attention/issues/358>`_), which may lead to out of memory errors during the installation of Transformer Engine. Please try setting **MAX_JOBS=1** in the environment to circumvent the issue.

.. troubleshooting-begin-marker-do-not-remove

Troubleshooting
^^^^^^^^^^^^^^^

**Common Issues and Solutions:**

1. **ABI Compatibility Issues:**

   * **Symptoms:** ``ImportError`` with undefined symbols when importing transformer_engine
   * **Solution:** Ensure PyTorch and Transformer Engine are built with the same C++ ABI setting. Rebuild PyTorch from source with matching ABI.
   * **Context:** If you're using PyTorch built with a different C++ ABI than your system's default, you may encounter these undefined symbol errors. This is particularly common with pip-installed PyTorch outside of containers.

2. **Missing Headers or Libraries:**

   * **Symptoms:** CMake errors about missing headers (``cudnn.h``, ``cublas_v2.h``, ``filesystem``, etc.)
   * **Solution:** Install missing development packages or set environment variables to point to correct locations:

     .. code-block:: bash

         export CUDA_PATH=/path/to/cuda
         export CUDNN_PATH=/path/to/cudnn

   * If CMake can't find a C++ compiler, set the ``CXX`` environment variable.
   * Ensure all paths are correctly set before installation.

3. **Build Resource Issues:**

   * **Symptoms:** Compilation hangs, system freezes, or out-of-memory errors
   * **Solution:** Limit parallel builds:

     .. code-block:: bash

         MAX_JOBS=1 NVTE_BUILD_THREADS_PER_JOB=1 pip install ...

4. **Verbose Build Logging:**

   * For detailed build logs to help diagnose issues:

     .. code-block:: bash

         cd transformer_engine
         pip install -v -v -v --no-build-isolation .

**Problems using UV or Virtual Environments:**

1. **Import Error:**

   * **Symptoms:** Cannot import ``transformer_engine``
   * **Solution:** Ensure your UV environment is active and that you have used ``uv pip install --no-build-isolation <te_pypi_package_or_wheel_or_source_dir>`` instead of a regular pip install to your system environment.

2. **cuDNN Sublibrary Loading Failed:**

   * **Symptoms:** Errors at runtime with ``CUDNN_STATUS_SUBLIBRARY_LOADING_FAILED``
   * **Solution:** This can occur when TE is built against the container's system installation of cuDNN, but pip packages inside the virtual environment pull in pip packages for ``nvidia-cudnn-cu12/cu13``. To resolve this, when building TE from source please specify the following environment variables to point to the cuDNN in your virtual environment.
   
   
     .. code-block:: bash

        export CUDNN_PATH=$(pwd)/.venv/lib/python3.12/site-packages/nvidia/cudnn
        export CUDNN_HOME=$CUDNN_PATH
        export LD_LIBRARY_PATH=$CUDNN_PATH/lib:$LD_LIBRARY_PATH

3. **Building Wheels:**

   * **Symptoms:** Regular TE installs work correctly but UV wheel builds fail at runtime.
   * **Solution:** Ensure that ``uv build --wheel --no-build-isolation -v`` is used during the wheel build as well as the pip installation of the wheel. Use ``-v`` for verbose output to verify that TE is not pulling in a mismatching version of PyTorch or JAX that differs from the UV environment's version.

**JAX-specific Common Issues and Solutions:**

1. **FFI Issues:**

   * **Symptoms:** ``No registered implementation for custom call to <some_te_ffi> for platform CUDA``
   * **Solution:** Ensure ``--no-build-isolation`` is used during installation. If pre-building wheels, ensure that the wheel is both built and installed with ``--no-build-isolation``. See "Problems using UV or Virtual Environments" above if using UV.

Breaking Changes
================

v1.7: Padding mask definition for PyTorch
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In an effort to unify the definition and usage of the attention mask across all three frameworks in Transformer Engine, the padding mask has changed from `True` meaning inclusion of the corresponding position in attention to exclusion of that position in our PyTorch implementation. Since v1.7, all attention mask types follow the same definition where `True` means masking out the corresponding position and `False` means including that position in attention calculation.

An example of this change is,

.. code-block:: bash

    # for a batch of 3 sequences where `a`s, `b`s and `c`s are the useful tokens
    # and `0`s are the padding tokens,
    [a, a, a, 0, 0,
     b, b, 0, 0, 0,
     c, c, c, c, 0]
    # the padding mask for this batch before v1.7 is,
    [ True,  True,  True, False, False,
      True,  True, False, False, False,
      True,  True,  True,  True, False]
    # and for v1.7 onwards it should be,
    [False, False, False,  True,  True,
     False, False,  True,  True,  True,
     False, False, False, False,  True]

FP8 Convergence
===============

FP8 has been tested extensively across different model architectures and configurations and we found **no significant difference** between FP8 and BF16 training loss curves. FP8 has also been validated for accuracy on downstream LLM tasks (e.g. LAMBADA and WikiText). Below are examples of models tested for convergence across different frameworks.
