For now I have renamed the one call in the <em>installed</em> pytest at Subaru.</p> PIPE2D-597 DRP and ICS have conflicting requirements for {{attrs}} package version Task Normal Open Unresolved price cloomis Wed, 3 Jun 2020 00:47:39 +0000 Mon, 12 Sep 2022 14:35:40 +0000 0 3 <p>To be clear I think we can skate on this one: the hack is gross but <b>really</b> limited both in size and location. It will never become a support issue outside of me and Arnaud. </p> <p>It would be nice to know whether there are any plans to update the pytest package.</p> <p>I don't intend to update the pytest package explicitly, but it will be updated as a side effect of upgrading the LSST stack in the future.</p> <p>Moved this to top of backlog for moment. </p> <p>To be prescriptive:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>(lsst-scipipe-1172c30) -bash-4.2$ diff ./3.6.2.lsst2+2/lib/python/pytest-3.6.2-py3.7.egg/_pytest/mark/structures.py~ ./3.6.2.lsst2+2/lib/python/pytest-3.6.2-py3.7.egg/_pytest/mark/structures.py 284c284 &lt; _marks = attr.ib(convert=list) --- &gt; _marks = attr.ib(converter=list) </pre> </div></div> <p>Forgot to explicitly add that the <tt>attrs</tt> conda package does need to be updated. 19.3.0 is what we have tested with.</p> <p><a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=cloomis" class="user-hover" rel="cloomis">cloomis</a>: Is this still a problem?</p> Blocks PIPE2D-506 Development Rank 0|02qpq3:r3s00001 Story Points 4.0
