You can install it by running <code>python -m pip install --upgrade pip</code>.</p> <p>This is an important and disruptive release -- we <a href="https://pyfound.blogspot.com/2019/12/moss-czi-support-pip.html" rel="nofollow">explained why in a blog post last year</a>. We've even made <a href="https://www.youtube.com/watch?v=B4GQCBBsuNU" rel="nofollow">a video about it</a>.</p> <p><iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" frameborder="0" height="315" src="https://www.youtube-nocookie.com/embed/B4GQCBBsuNU" width="560"></iframe></p> <h2 style="text-align: left;">Highlights</h2> <ul><li> <p><b>DISRUPTION</b>: Switch to the new dependency resolver by default.

To keep the previous behavior, users should use the new <code>--exclude</code> option.</p> </li><li> <p>Substantial improvements in new resolver for performance, output and error messages, avoiding infinite loops, and support for constraints files.</p> </li><li> <p>Support for PEP 600: Future <code>manylinux</code> Platform Tags for Portable Linux Built Distributions.</p> </li><li> <p>Documentation improvements: Resolver migration guide, quickstart guide, and new documentation theme.</p> </li><li> <p>Add support for MacOS Big Sur compatibility tags.</p> </li></ul> <p>The new resolver is now <i>on by default</i> for Python 3 users. It is significantly stricter and more consistent when it receives incompatible instructions, and reduces support for certain kinds of constraints files, so some workarounds and workflows may break.

This has helped the team make decisions to improve pip, such as <a href="https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies">error messages and documentation to help you fix dependency conflicts</a>.</p> <p>Our team has put together a <a href="https://pip.pypa.io/en/latest/ux_research_design/">User Experience (UX) section in pip's documentation</a> to tell you about this UX work. It covers what has happened so far, how you can contribute, and what is coming in the future.</p> <h3>Contribute to current UX work</h3> <p>Right now, you can take part in a number of studies about:</p> <ol><li>What pip features do you use most, and what pip feature you'd like to see - <a href="https://docs.google.com/forms/d/1N-sE0LxdfZb2OUsBcwNILabnpPsb71IRAMWD9CKY6Uk/">give your input by completing this survey</a></li><li>How "<span style="font-family: courier;">pip force install</span>" should behave - <a href="https://docs.google.com/forms/d/1otpC59Yo667l9fiPPLPz8ivKr4GO3atXwy-B6pFhL1U">give your input by completing this survey</a></li><li>How "<span style="font-family: courier;">pip --force-reinstall</span>" should behave - <a href="https://docs.google.com/forms/d/1S2sAQMCmqJiS4Qp4HnRH196ph4oiS0nRhg9FgZMJzbg">give your input by completing this survey</a></li><li>Help create a design brief for a pip logo - <a href="https://docs.google.com/forms/d/17zzrIQVt-UymVSWPlKVZdci1HqNIvSGXmhNJbL9DYdA">give your input by completing this survey</a></li><li>What is your experience of using pip search - <a href="https://docs.google.com/forms/d/1-4kiVV8NnlkBrCr6x7eb8SobnS1RVRAR2xEl8iUeu24">give your input by completing this survey</a></li></ol> <p>If you have time, the team asks for you to answer all of these surveys. You can do them in your own time, all at once or over a few days.</p> <p>At the end of these surveys you can give your email address to be contacted for a short interview. These interviews will be via web conference/videocall.</p> <h3>Contribute to future pip UX work</h3> <p>If you want to contribute to our UX work in the future, please <a href="https://bit.ly/pip-ux-studies">sign up to become a member of the UX Studies group</a>.</p> <p>After you join, we'll notify you about future UX Studies (surveys and interviews).</p> <h3>Contacting the pip UX Team</h3> <p>You can contact the pip UX Team <a class="notion-link-token notion-enable-hover" data-reactroot="" data-token-index="2" href="mailto:pip-ux@pypa.io?subject=Contact%20from%20PSF%20blog" rel="noopener noreferrer" style="color: inherit; cursor: pointer; overflow-wrap: break-word; text-decoration: inherit;" target="_blank"><span style="border-bottom: 0.05em solid rgba(55, 53, 47, 0.4); border-color: rgba(55, 53, 47, 0.4); opacity: 0.7;">by</span></a><a class="notion-link-token notion-enable-hover" data-reactroot="" data-token-index="3" href="mailto:pip-ux@pypa.io" rel="noopener noreferrer" style="color: inherit; cursor: pointer; overflow-wrap: break-word; text-decoration: inherit;" target="_blank"><span style="border-bottom: 0.05em solid rgba(55, 53, 47, 0.4); border-color: rgba(55, 53, 47, 0.4); opacity: 0.7;"> email</span></a>. <br /></p> <p>We look forward to talking with you!</p><p style="text-align: right;">-Bernard Tyers, user experience, pip team </p><p style="text-align: right;">Sumana Harihareswara, project manager, pip team<br /></p> <div style='clear: both;'></div> </div> <div class='post-footer'> <div class='post-footer-line post-footer-line-1'> <span class='post-author vcard'> Posted by <span class='fn' itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://www.blogger.com/profile/08002085909817689325' itemprop='url'/> <a class='g-profile' href='https://www.blogger.com/profile/08002085909817689325' rel='author' title='author profile'> <span itemprop='name'>Sumana Harihareswara</span> </a> </span> </span> <span class='post-timestamp'> at <meta content='https://pyfound.blogspot.com/2020/09/answer-surveys-improve-pip-ux.html' itemprop='url'/> <a class='timestamp-link' href='https://pyfound.blogspot.com/2020/09/answer-surveys-improve-pip-ux.html' rel='bookmark' title='permanent link'><abbr class='published' itemprop='datePublished' title='2020-09-15T08:17:00-04:00'>9/15/2020 08:17:00 AM</abbr></a> </span> <span class='post-comment-link'> </span> <span class='post-icons'> <span class='item-control blog-admin pid-1436657185'> <a href='https://www.blogger.com/post-edit.g?blogID=8520&postID=7077217817458778019&from=pencil' title='Edit Post'> <img alt='' class='icon-action' height='18' src='https://resources.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/> </a> </span> </span> <div class='post-share-buttons goog-inline-block'> </div> </div> <div class='post-footer-line post-footer-line-2'> <span class='post-labels'> Labels: <a href='https://pyfound.blogspot.com/search/label/grant' rel='tag'>grant</a>, <a href='https://pyfound.blogspot.com/search/label/grants' rel='tag'>grants</a>, <a href='https://pyfound.blogspot.com/search/label/open%20source' rel='tag'>open source</a>, <a href='https://pyfound.blogspot.com/search/label/pip' rel='tag'>pip</a>, <a href='https://pyfound.blogspot.com/search/label/user%20experience' rel='tag'>user experience</a>, <a href='https://pyfound.blogspot.com/search/label/volunteer' rel='tag'>volunteer</a> </span> </div> <div class='post-footer-line post-footer-line-3'> <span class='post-location'> </span> </div> </div> </div> </div> </div></div> <div class="date-outer"> <h2 class='date-header'><span>Monday, July 13, 2020</span></h2> <div class="date-posts"> <div class='post-outer'> <div class='post hentry uncustomized-post-template' itemprop='blogPost' itemscope='itemscope' itemtype='http://schema.org/BlogPosting'> <meta content='8520' itemprop='blogId'/> <meta content='6298634573721150667' itemprop='postId'/> <a name='6298634573721150667'></a> <h3 class='post-title entry-title' itemprop='name'> <a href='https://pyfound.blogspot.com/2020/07/pip-team-midyear-report.html'>Pip team midyear report</a> </h3> <div class='post-header'> <div class='post-header-line-1'></div> </div> <div class='post-body entry-content' id='post-body-6298634573721150667' itemprop='description articleBody'> <div class="ace-line" id="magicdomid2" spellcheck="true"> <h1> <span class="author-a-z73zgetx1z90zmorz71z06z86zjo"></span></h1> </div> <div class="ace-line" id="magicdomid3" spellcheck="true"> </div> <div class="ace-line" id="magicdomid5" spellcheck="true"> <span class="author-a-z73zgetx1z90zmorz71z06z86zjo">The <a href="https://pyfound.blogspot.com/2020/03/new-pip-resolver-to-roll-out-this-year.html">grant-funded team working on improvements to pip</a></span><span class="author-a-z73zgetx1z90zmorz71z06z86zjo"> in 2020 has now passed the halfway mark.

We aim to roll it out later this year. (<i>Updated 29 September</i> to add: <a href="https://pip.pypa.io/en/latest/user_guide/#resolver-changes-2020">see our migration guide</a>.) As part of that work, there will be some major changes to how pip determines what to install, based on package requirements. In this post we share:</p><p><b><a href="#what-will-change">What will change</a></b><br /> <b><a href="#what-you-can-do-to-help">What you can do to help</a></b><br /> <b><a href="#when-this-will-be-happening">When this will be happening</a></b></p><p>To understand what pip does and why we’re working on it, please read <a href="https://pyfound.blogspot.com/2019/12/moss-czi-support-pip.html">our earlier overview post</a>.</p><h2 id="what-will-change">What will change</h2><p>The most significant changes to the resolver will be:</p><ul><li>It will <b>reduce inconsistency</b>: it will <i>no longer install a combination of packages that is mutually inconsistent</i>. At the moment, it is possible for pip to install a package which does not satisfy the declared requirements of another installed package. For example, right now, <code>pip install "six<1.12" "virtualenv==20.0.2"</code> does the wrong thing, “successfully” installing <code>six==1.11</code>, even though <code>virtualenv==20.0.2</code> requires <code>six>=1.12.0,<2</code> (<a href="https://github.com/pypa/virtualenv/blob/20.0.2/setup.cfg#L42-L50">defined here</a>). The new resolver would, instead, outright reject installing anything if it got that input.</li> <li>It will be <b>stricter</b> - if you ask pip to install two packages with incompatible requirements, it will refuse (rather than installing a broken combination, like it does now).</li> </ul><p>Also, this is <b>a major change to a key part of pip</b> - it’s quite possible there will initially be bugs. We would like to make sure that those get caught <i>before</i> people start using the new version in production.</p><p>(For deep technical details, see <a href="https://github.com/pypa/pip/projects/5">this in-progress GitHub milestone</a>.)</p><h2 id="what-you-can-do-to-help">What you can do to help</h2><p>We recognize that everyone’s work is being disrupted by the COVID-19 pandemic, and that many data scientists and medical researchers use Python and pip in their work. We want to make the upgrade process as smooth and bug-free as possible for our users; if you can help us, you’ll be helping each other.</p><ol type="1"><li><p>First and most fundamentally, <a href="https://bit.ly/pip-ux-studies">please help us understand how you use pip by <b>talking with our user experience researchers</b></a>. You can do this right now! You can take a survey, or have a researcher interview you over a video call. <a href="https://bit.ly/pip-ux-studies">Please sign up and spread the word</a> to anyone who uses pip (even a little bit).</p></li> <li><p>Right now, even before we release the new resolver as a beta, you can help by <b>running <code>pip check</code> on your current environment</b>. This will report if you have any inconsistencies in your set of installed packages. Having a clean installation will make it much less likely that you will hit issues when the new resolver is released (and may address hidden problems in your current environment!). If you run <code>pip check</code> and run into stuff you can’t figure out, please <a href="https://pip.pypa.io/">ask for help in our issuetracker or chat</a>.</p></li> <li><p>Please make time to <b><i>test</i> the new version of pip, probably in May</b> (see below). While we have tried to make sure that pip’s test suite covers as many cases as we can, we are very aware that there are people using pip with many different workflows and build processes, and we will not be able to cover all of those without your help.</p><ul><li>If you use pip to install your software, try out the new resolver and let us know if it works for you.</li> <li>If you have a build pipeline that depends on pip installing your dependencies for you, check that the new resolver does what you need.</li> <li>Run your project’s CI (test suite, build process, etc.) using the new resolver, and let us know of any issues.</li> <li>If you have encountered resolver issues with pip in the past, check whether the new resolver fixes them. Also, let us know if the new resolver has issues with any workarounds you put in to address the current resolver’s limitations. We’ll need to ensure that people can transition off such workarounds smoothly.</li> </ul><p>As you and your colleagues plan for the next few months, please set aside time, ideally in May, to test the new resolver and <a href="https://tools.simplysecure.org/survey/index.php?r=survey/index&sid=989272&lang=en">tell us whether it breaks anything for your setup by filling out this survey</a>. If you maintain an open source project or use pip at your job, you can make a ticket now and put it in your backlog.</p></li> <li><p><b>Spread the word!</b> If you know of other people who rely on pip, who might not have seen this message, let them know. You can do this right now.</p></li> <li><p>And if you develop or support a tool that wraps pip or uses it to deliver part of your functionality, please make time to <b>test your integration with our beta in May</b>, and sure that the new resolver doesn’t cause you any issues. (It shouldn’t, as the resolver is an internal component of pip and shouldn’t be visible to people embedding pip, but we’d like to be sure of that.)</p></li> </ol><h2 id="when-this-will-be-happening">When this will be happening</h2><p>We intend to release the new resolver early in the second half of 2020. We will provide <b>alpha and beta releases</b> before that point as the work progresses (probably starting in <b>May</b>), and we’ll provide a GitHub issue tracker and an email address where you can report bugs. We would appreciate as much feedback as we can get on the betas when they become available.</p><p>(We were already working as a distributed team. The COVID-19 pandemic and related disruptions are affecting us – for instance, we were aiming to meet, work together, and test and discuss our work at PyCon US. But we still anticipate releasing the new resolver in the second half of 2020.)</p><p>To find out when the new beta is available for testing, and how to report problems, <b><a href="https://mail.python.org/mailman3/lists/pypi-announce.python.org/">subscribe to the pypi-announce mailing list</a></b>. It’s very low-traffic.</p><p>(Why now? The Python Software Foundation’s Packaging Working Group <a href="https://pyfound.blogspot.com/2019/12/moss-czi-support-pip.html">obtained funding for this work</a> because it’s sorely needed; <a href="https://wiki.python.org/psf/Fundable%20Packaging%20Improvements#Finish_dependency_resolver_for_pip">many other features and tools are blocked waiting for this fix</a>.

This foundational, transformational work will release Python developers and users to concentrate on the tools they're making and using, instead of troubleshooting dependency conflicts.

So, when programmers share software, we have to precisely describe those installation prerequisites, and our installation tools need to navigate tricky situations where they're getting conflicting instructions. This project will make pip, a package installer for Python, better at handling that tricky logic, and easier for people to use and troubleshoot.<br /> <br /> Millions of people and organizations use tools written in Python, and nearly the entire ecosystem of Python software projects depends on pip. Our project will help everyone more easily install software, diagnose and fix problems, and maintain infrastructure.<br /> <br /> The Chan Zuckerberg Initiative funding is, in particular, aimed at improving <a href="https://chanzuckerberg.com/eoss/">Essential Open Source Software for Science</a>. Scientists use many tools written in Python --<a href="https://chanzuckerberg.com/newsroom/chan-zuckerberg-initiative-awards-5-million-for-open-source-software-projects-essential-to-science/"> many of CZI's awardees in this round are written in Python</a> -- but, also, researchers often want to write tools and share them with each other to help science advance faster. Our work will include research and improvements so the installation process will be easier to use and understand, which will enable researchers to build better applications and compose complex toolchains more easily.<br /> <br /> We've laid out a detailed three-phase work plan on<a href="https://wiki.python.org/psf/Pip2020DonorFundedRoadmap"> our pip 2020 Donor-funded Roadmap wiki page</a>. To summarize:<br /> <br /> <ul> <li><b>Mozilla</b> is awarding PSF a<a href="https://mozilla.org/moss"> Mozilla Open Source Support Award</a> (<a href="https://www.mozilla.org/en-US/moss/foundational-technology/">Track I: Foundational Technology</a>) for $207,000, which is paying for 5 months of: </li> <ul> <li><b>Python development work</b>: Reviewing and responding to open issues and pull requests, refactoring build logic, collaborating with downstream projects and users about config flags and transition schedules, working on the dependency resolver itself and fixing bugs. </li> </ul> <ul> <li><b>Initial user experience research and design work</b>: Reading existing bug reports and posts about Python package management confusion, interviewing users and running user tests, developing user journey maps and workflows, and working with maintainers to write documentation and help messages and to design resolver user experience. </li> </ul> <li><b>CZI</b> is giving PSF an<a href="https://chanzuckerberg.com/eoss/"> Essential Open Source Software for Science</a> grant for $200,000, which is paying for: </li> <ul> <li>12 months of <b>Python development, test infrastructure, and project maintenance</b>: Triaging bugs and reviewing pull requests, writing test cases, testing lead developers' work, building test infrastructure, investigating and fixing bugs, and writing the raw material for documentation to help future maintainers onboard better. </li> </ul> <ul> <li>4 months of <b>Phase III user experience research and design work</b>: Training maintainers in UX design, doing further user tests on the new pip, developing a checklist for developing new features, and making templates for commands, error messages, output, documentation, and config files. </li> <li><b>Travel</b> for initial developer onboarding and for some contributors to attend<a href="https://us.pycon.org/2020/"> PyCon North America</a>. </li> </ul> <li>And both CZI and Mozilla are paying for <b>project management</b> (planning, testing, editing, coordinating, communicating with stakeholders, announcing, reporting to funders, and getting obstacles out of everyone's way) and <b>PSF administrative work</b> (recruiting and overseeing contractors, project oversight, and financial processing). </li> </ul> The Packaging Working Group is<a href="https://github.com/python/request-for/blob/master/2020-pip/RFP.md"> currently selecting contractors for the programming parts of this work</a>. The other two contractors have already been selected:<br /> <ul> <li><i><a href="https://simplysecure.org/">Simply Secure</a></i> is "an educational nonprofit 501(c)3 that supports practitioners in designing ethically-informed, values-driven technology that protects human rights." As experts in open source user experience, Simply Secure will bring UX research and design skills to the command-line experience of Python package management. </li> <li><i><a href="https://changeset.nyc/">Changeset Consulting, LLC</a></i>, providing project management, is a returning contractor, having previously worked on<a href="http://pyfound.blogspot.com/2017/11/the-psf-awarded-moss-grant-pypi.html"> the PyPI rewrite launch</a> and<a href="https://pyfound.blogspot.com/2019/03/commencing-security-accessibility-and.html"> improvements to PyPI's accessibility, security, and internationalization</a>. Changeset lead Sumana Harihareswara was also the lead grantwriter for these funding proposals. </li> </ul> <h3>  </h3> <h3> Why this and why now?</h3> We're partway through a next-generation rewrite of pip's dependency resolver. The project ran into massive technical debt, but the refactoring is nearly finished and prototype functionality is in alpha now.<br /> <br /> We need to finish the resolver<a href="https://wiki.python.org/psf/Fundable%20Packaging%20Improvements#Finish_dependency_resolver_for_pip"> because many other packaging improvements are blocked on it, it'll fix many dependency issues for Python users, and it'll fix installation problems for conda, certbot, WebSocket, and many other projects</a>. And we need to improve pip's UX<a href="https://wiki.python.org/psf/Fundable%20Packaging%20Improvements#Improve_pip_user_experience"> by providing better error messages and prompts, logs, output, and reporting, consistently across features, to fit users' mental models better, make hairy problems easier to untangle, and reduce unintended data loss</a>.<br /> <br /> The<a href="https://wiki.python.org/psf/PackagingWG"> Packaging Working Group</a> looks for<a href="https://wiki.python.org/psf/Fundable%20Packaging%20Improvements"> potential improvements in Python packaging and distribution that are well-scoped, have community consensus, and could be expedited through funding</a>. In the past three years, the Packaging WG has received funding for<a href="https://wiki.python.org/psf/PackagingWG#Past%20projects"> several improvements to PyPI</a> -- $170,000 from Mozilla, $80,000 from OTF, and $100,000 from Facebook -- and is seeking to help other packaging tools. In June,<a href="https://github.com/pypa/pip/issues/6536"> pip maintainers and Packaging Working Group members discussed the importance and difficulty of rolling out the new resolver</a>. We worked together to write and submit proposals to Mozilla and the Chan Zuckerberg Initiative.<br /> <h3>  </h3> <h3> What's next?</h3> This work will start by early January 2020. Day-to-day work will mostly happen in<a href="https://github.com/pypa/pip/"> pip's GitHub repository</a> and<a href="https://python.zulipchat.com/"> the Python developers' Zulip livechat</a>. You can check for regular reports at<a href="https://blog.python.org/"> the Python Insider blog</a> and<a href="https://discuss.python.org/c/packaging"> the Packaging category of Python's Discourse developer forum</a>, archived at<a href="https://wiki.python.org/psf/PackagingWG"> the Packaging WG's wiki page</a>. And we'll publicize calls for volunteers, especially for user interviews and tests, on this blog, on<a href="https://www.python.org/community/lists/"> community mailing lists</a>, and on<a href="https://twitter.com/ThePSF"> Twitter</a>.<br /> <br /> The Packaging WG will continue to seek funding for<a href="https://wiki.python.org/psf/Fundable%20Packaging%20Improvements#Packaging_improvements_that_could_be_funded"> future improvements in pip, manylinux, setuptools, the Python Packaging User Guide, PyPI, etc.</a><br /> <h3>  </h3> <h3> Thanks</h3> This award continues our relationship with Mozilla, which supported Python packaging tools with<a href="https://pyfound.blogspot.com/2017/11/the-psf-awarded-moss-grant-pypi.html"> a Mozilla Open Source Support Award in 2017 for Warehouse</a>.
