Applications which integrate NVTX can use NVIDIA Nsight Systems and Nsight Compute to capture and visualize these events and time ranges. .. figure:: docs/images/nvtx_demo.jpg The NVTX ranges are added by wrapping regions of the computation graph with nvtx start and end operations. .. figure:: docs/images/nvtx_graph.svg NVTX Plugins also provides Keras callbacks and session hooks.

Building the documentation ^^^^^^^^^^^^^^^^^^^^^^^^^^ The documentation is built by running: .. code-block:: bash cd docs pip install -r requirements.txt make html The documentation files will be generated in `docs/build/html` Building the documentation does not require NVTX Plugins to be installed. Nonetheless, due to an issue in Sphinx **only Python 3.7 is supported** to build the documentation. ---- Quick start guide ----------------- Adding markers to the graph ^^^^^^^^^^^^^^^^^^^^^^^^^^^ Markers are added by wrapping parts of the computation graph with start and end operations. The operations are identity ops (passing the input to the output without modification) but they have a side effect of generating nvtx markers. .. code-block:: python import nvtx.plugins.tf as nvtx_tf x, nvtx_context = nvtx_tf.ops.start(x, message='Dense 1-3', domain_name='Forward', grad_domain_name='Gradient') x = tf.layers.dense(x, 1000, activation=tf.nn.relu, name='dense_1') x = tf.layers.dense(x, 1000, activation=tf.nn.relu, name='dense_2') x = tf.layers.dense(x, 1000, activation=tf.nn.relu, name='dense_3') x = nvtx_tf.ops.end(x, nvtx_context) x = tf.layers.dense(x, 1000, activation=tf.nn.relu, name='dense_4') For convenience, the package also provides a function dectorator: .. code-block:: python @nvtx_tf.ops.trace(message='Dense Block', domain_name='Forward', grad_domain_name='Gradient') def dense_block(x): x = tf.layers.dense(x, 1000, activation=tf.nn.relu, name='dense_1') x = tf.layers.dense(x, 1000, activation=tf.nn.relu, name='dense_2') x = tf.layers.dense(x, 1000, activation=tf.nn.relu, name='dense_3') return x More detailed examples can be found in `examples/`, also, check the Documentation_ for more information about other workflows including session hooks, Keras layers and callbacks. Visualizing the ranges ^^^^^^^^^^^^^^^^^^^^^^ NVTX requires a logger to register the generated events and ranges, we will use NVIDIA Nsight Systems to capture these event. Run your code with `nsys` (pre-installed in NVIDIA's NGC TensorFlow container) to generate a `qdrep` file: .. code-block:: bash nsys profile -d 60 \ -w true \ --sample=cpu \ -t 'nvtx,cuda' \ -o ./generated_timeline \ python ./network.py The generated qdrep can be viewed using Nsight Systems. Nsight Systems and `nsys` can also be downloaded and from the `NVIDIA''s developer website `_. More details about nsys and Nsight Systems can be found `here `_. ---- Documentation ------------- More details about NVTX Plugins can be found on here: https://nvtx-plugins.readthedocs.io/en/latest/ ---- Acknowledgments --------------- The project structure is heavily influenced by the TensorFlow custom-op example: https://github.com/tensorflow/custom-op ---- Disclaimer ---------- The project is in beta stage, breaking changes are to be expected in the future. ---- Contributions ------------- Contributions to NVTX Plugins are more than welcome. To contribute code, please submit a `pull request `_ against the master branch from a local fork. We appreciate feedback, questions or bug reports. If you need help with the code, create a `GitHub issue `_. Please follow the process outlined in the Stack Overflow ``_ document. Ensure that the posted examples are: - **minimal**: Use as little code as possible that still produces the same problem. - **complete**: Provide all parts needed to reproduce the problem. Check if you can strip external dependency and still show the problem. The less time we spend on reproducing the problems, the more time we can dedicate to the fixes. - **verifiable**: Test the code you are about to provide, to make sure that it reproduces the problem. Remove all other problems that are not related to your request. ---- Copyright and License --------------------- This project is released under the Apache License, Version 2.0 .. |License| image:: https://img.shields.io/badge/License-Apache%202.0-blue.svg :target: https://opensource.org/licenses/Apache-2.0 .. |Documentation| image:: https://readthedocs.com/projects/nvidia-nvtx-plugins/badge/?version=latest :target: https://nvidia-nvtx-plugins.readthedocs-hosted.com/deeplearning/frameworks/nvtx-plugins/user-guide/docs/en/latest/?badge=latest :alt: Documentation Status .. |Release| image:: https://img.shields.io/github/release/nvidia/nvtx-plugins.svg :target: https://github.com/NVIDIA/nvtx-plugins/releases/ .. |PyPI-Version| image:: https://img.shields.io/pypi/pyversions/nvtx-plugins.svg :target: https://pypi.org/project/nvtx-plugins/ :alt: PyPI - Implementation .. |PyPI-Implementation| image:: https://img.shields.io/pypi/implementation/nvtx-plugins.svg :target: https://pypi.org/project/nvtx-plugins/ :alt: PyPI - Implementation .. |Circle-CI| image:: https://circleci.com/gh/NVIDIA/nvtx-plugins.svg?style=shield :target: https://circleci.com/gh/NVIDIA/nvtx-plugins
