<h1>PyTorch Contribution Guide<a class="headerlink" href="#pytorch-contribution-guide" title="Permalink to this headline">¶</a></h1>
<p>PyTorch is a GPU-accelerated Python tensor computation package for
building deep neural networks built on tape-based autograd systems.</p>
<div class="section" id="the-pytorch-contribution-process">
<h2>The PyTorch Contribution Process<a class="headerlink" href="#the-pytorch-contribution-process" title="Permalink to this headline">¶</a></h2>
<p>The PyTorch organization is governed by <a class="reference internal" href="governance.html"><span class="doc">PyTorch
Governance</span></a>.</p>
<p>The PyTorch development process involves a healthy amount of open
discussions between the core development team and the community.</p>
<p>PyTorch operates similar to most open source projects on GitHub.
However, if you’ve never contributed to an open source project before,
here is the basic process.</p>
<ul class="simple">
<li><p><strong>Figure out what you’re going to work on.</strong> The majority of open
source contributions come from people scratching their own itches.
However, if you don’t know what you want to work on, or are just
looking to get more acquainted with the project, here are some tips
for how to find appropriate tasks:</p>
<ul>
<li><p>Look through the <a class="reference external" href="https://github.com/pytorch/pytorch/issues/">issue
tracker</a> and see if
there are any issues you know how to fix. Issues that are
confirmed by other contributors tend to be better to investigate.
We also maintain some labels for issues which are likely to be
good for new people, e.g., <strong>bootcamp</strong> and <strong>1hr</strong>, although
these labels are less well maintained.</p></li>
<li><p>Join us on Slack and let us know you’re interested in getting to
know PyTorch. We’re very happy to help out researchers and
partners get up to speed with the codebase.</p></li>
</ul>
</li>
<li><p><strong>Figure out the scope of your change and reach out for design
comments on a GitHub issue if it’s large.</strong> The majority of pull
requests are small; in that case, no need to let us know about what
you want to do, just get cracking. But if the change is going to be
large, it’s usually a good idea to get some design comments about it
first.</p>
<ul>
<li><p>If you don’t know how big a change is going to be, we can help you
figure it out! Just post about it on issues or Slack.</p></li>
<li><p>Some feature additions are very standardized; for example, lots of
people add new operators or optimizers to PyTorch. Design
discussion in these cases boils down mostly to, “Do we want this
operator/optimizer?” Giving evidence for its utility, e.g., usage
in peer reviewed papers, or existence in other frameworks, helps a
bit when making this case.</p>
<ul>
<li><p><strong>Adding operators / algorithms from recently-released research</strong>
is generally not accepted, unless there is overwhelming evidence that
this newly published work has ground-breaking results and will eventually
become a standard in the field. If you are not sure where your method falls,
open an issue first before implementing a PR.</p></li>
</ul>
</li>
<li><p>Core changes and refactors can be quite difficult to coordinate,
as the pace of development on PyTorch master is quite fast.
Definitely reach out about fundamental or cross-cutting changes;
we can often give guidance about how to stage such changes into
more easily reviewable pieces.</p></li>
</ul>
</li>
<li><p><strong>Code it out!</strong></p>
<ul>
<li><p>See the technical guide for advice for working with PyTorch in a
technical form.</p></li>
</ul>
</li>
<li><p><strong>Open a pull request.</strong></p>
<ul>
<li><p>If you are not ready for the pull request to be reviewed, tag it
with [WIP]. We will ignore it when doing review passes. If you are
working on a complex change, it’s good to start things off as WIP,
because you will need to spend time looking at CI results to see
if things worked out or not.</p></li>
<li><p>Find an appropriate reviewer for your change. We have some folks
who regularly go through the PR queue and try to review
everything, but if you happen to know who the maintainer for a
given subsystem affected by your patch is, feel free to include
them directly on the pull request. You can learn more about this
structure at PyTorch Subsystem Ownership.</p></li>
</ul>
</li>
<li><p><strong>Iterate on the pull request until it’s accepted!</strong></p>
<ul>
<li><p>We’ll try our best to minimize the number of review roundtrips and
block PRs only when there are major issues. For the most common
issues in pull requests, take a look at <a class="reference external" href="#common-mistakes-to-avoid">Common Mistakes</a>.</p></li>
<li><p>Once a pull request is accepted and CI is passing, there is
nothing else you need to do; we will merge the PR for you.</p></li>

<div class="section" id="about-open-source-development">
<h2>About open source development<a class="headerlink" href="#about-open-source-development" title="Permalink to this headline">¶</a></h2>
<p>If this is your first time contributing to an open source project, some
aspects of the development process may seem unusual to you.</p>
<ul class="simple">
<li><p><strong>There is no way to “claim” issues.</strong> People often want to “claim”
an issue when they decide to work on it, to ensure that there isn’t
wasted work when someone else ends up working on it. This doesn’t
really work too well in open source, since someone may decide to work
on something, and end up not having time to do it. Feel free to give
information in an advisory fashion, but at the end of the day, we
will take running code and rough consensus.</p></li>
<li><p><strong>There is a high bar for new functionality that is added.</strong> Unlike
in a corporate environment, where the person who wrote code
implicitly “owns” it and can be expected to take care of it in the
beginning of its lifetime, once a pull request is merged into an open
source project, it immediately becomes the collective responsibility
of all maintainers on the project. When we merge code, we are saying
that we, the maintainers, are able to review subsequent changes and
make a bugfix to the code. This naturally leads to a higher standard
of contribution.</p></li>
</ul>
</div>
<div class="section" id="common-mistakes-to-avoid">
<h2>Common Mistakes To Avoid<a class="headerlink" href="#common-mistakes-to-avoid" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li><p><strong>Did you add tests?</strong> (Or if the change is hard to test, did you
describe how you tested your change?)</p>
<ul>
<li><p>We have a few motivations for why we ask for tests:</p>
<ol class="arabic simple">
<li><p>to help us tell if we break it later</p></li>
<li><p>to help us tell if the patch is correct in the first place
(yes, we did review it, but as Knuth says, “beware of the
following code, for I have not run it, merely proven it
correct”)</p></li>
</ol>
</li>
<li><p>When is it OK not to add a test? Sometimes a change can’t be
conveniently tested, or the change is so obviously correct (and
unlikely to be broken) that it’s OK not to test it. On the
contrary, if a change is seems likely (or is known to be likely)
to be accidentally broken, it’s important to put in the time to
work out a testing strategy.</p></li>
</ul>
</li>
<li><p><strong>Is your PR too long?</strong></p>
<ul>
<li><p>It’s easier for us to review and merge small PRs. Difficulty of
reviewing a PR scales nonlinearly with its size.</p></li>
<li><p>When is it OK to submit a large PR? It helps a lot if there was a
corresponding design discussion in an issue, with sign off from
the people who are going to review your diff. We can also help
give advice about how to split up a large change into individually
shippable parts. Similarly, it helps if there is a complete
description of the contents of the PR: it’s easier to review code
if we know what’s inside!</p></li>
</ul>
</li>
<li><p><strong>Comments for subtle things?</strong> In cases where behavior of your code
is nuanced, please include extra comments and documentation to allow
us to better understand the intention of your code.</p></li>
<li><p><strong>Did you add a hack?</strong> Sometimes a hack is the right answer. But
usually we will have to discuss it.</p></li>
<li><p><strong>Do you want to touch a very core component?</strong> In order to prevent
major regressions, pull requests that touch core components receive
extra scrutiny. Make sure you’ve discussed your changes with the team
before undertaking major changes.</p></li>
<li><p><strong>Want to add a new feature?</strong> If you want to add new features,
comment your intention on the related issue. Our team tries to
comment on and provide feedback to the community. It’s better to have
an open discussion with the team and the rest of the community prior
to building new features. This helps us stay aware of what you’re
working on and increases the chance that it’ll be merged.</p></li>
<li><p><strong>Did you touch unrelated code to the PR?</strong> To aid in code review,
please only include files in your pull request that are directly
related to your changes.</p></li>
</ul>
</div>
<div class="section" id="frequently-asked-questions">
<h2>Frequently asked questions<a class="headerlink" href="#frequently-asked-questions" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li><p><strong>How can I contribute as a reviewer?</strong> There is lots of value if
community developer reproduce issues, try out new functionality, or
otherwise help us identify or troubleshoot issues. Commenting on
tasks or pull requests with your environment details is helpful and
appreciated.</p></li>
<li><p><strong>CI tests failed, what does it mean?</strong> Maybe you need to merge with
master or rebase with latest changes. Pushing your changes should
re-trigger CI tests. If the tests persist, you’ll want to trace
through the error messages and resolve the related issues.</p></li>
<li><p><strong>What are the most high risk changes?</strong> Anything that touches build
configuration is an risky area. Please avoid changing these unless
you’ve had a discussion with the team beforehand.</p></li>
<li><p><strong>Hey, a commit showed up on my branch, what’s up with that?</strong>
Sometimes another community member will provide a patch or fix to
your pull request or branch. This is often needed for getting CI tests
to pass.</p></li>

<h3>C++ Docs<a class="headerlink" href="#c-docs" title="Permalink to this headline">¶</a></h3>

are built on a special server and the resulting files are copied to the

<h2>Tutorials<a class="headerlink" href="#tutorials" title="Permalink to this headline">¶</a></h2>
<p>PyTorch tutorials are documents used to help understand using PyTorch to
accomplish specific tasks or to understand more holistic concepts.
Tutorials are built using
<a class="reference external" href="https://sphinx-gallery.readthedocs.io/en/latest/index.html">Sphinx-Gallery</a>
from executable python sources files, or from restructured-text (rst)
files.</p>

<h3>Tutorials Build Overview<a class="headerlink" href="#tutorials-build-overview" title="Permalink to this headline">¶</a></h3>
<p>For tutorials, <a class="reference external" href="https://github.com/pytorch/tutorials/pulls">pull
requests</a> trigger a
rebuild the entire site using CircleCI to test the effects of the
change. This build is sharded into 9 worker builds and takes around 40
minutes total. At the same time, we do a Netlify build using <em>make
html-noplot</em>, which builds the site without rendering the notebook
output into pages for quick review.</p>
<p>After a PR is accepted, the site is rebuilt and deployed from CircleCI.</p>
