<p>Although we’ve tried to keep breaking changes to a minimum, upgrading from
spaCy v2.x to v3.x may still require some changes to your code base. For
details see the sections on <a class="link_root__1Me7D" href="/usage/v3#incompat">backwards incompatibilities</a>
and <a class="link_root__1Me7D" href="/usage/v3#migrating">migrating</a>. Also remember to download the new
trained pipelines, and retrain your own pipelines.</p>
</div></div></aside><p>When updating to a newer version of spaCy, it’s generally recommended to start
with a clean virtual environment. If you’re upgrading to a new major version,
make sure you have the latest <strong>compatible trained pipelines</strong> installed, and
that there are no old and incompatible packages left over in your environment,
as this can often lead to unexpected results and errors. If you’ve trained your
own models, keep in mind that your train and runtime inputs must match. This
means you’ll have to <strong>retrain your pipelines</strong> with the new version.</p><p>spaCy also provides a <a class="link_root__1Me7D link_nowrap__H7Oxl link_with-icon__NAVDA" href="/api/cli#validate"><code class="code_inline-code__Bq7ot">validate</code><svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" viewBox="0 0 20 20" class="icon_root__EGBLT link_icon__h3DMr icon_inline__1Eo2w" aria-hidden="true"><path d="M15.5 11h-11c-0.275 0-0.5 0.225-0.5 0.5v1c0 0.276 0.225 0.5 0.5 0.5h11c0.276 0 0.5-0.224 0.5-0.5v-1c0-0.275-0.224-0.5-0.5-0.5zM15.5 7h-11c-0.275 0-0.5 0.225-0.5 0.5v1c0 0.276 0.225 0.5 0.5 0.5h11c0.276 0 0.5-0.224 0.5-0.5v-1c0-0.275-0.224-0.5-0.5-0.5zM10.5 15h-6c-0.275 0-0.5 0.225-0.5 0.5v1c0 0.276 0.225 0.5 0.5 0.5h6c0.276 0 0.5-0.224 0.5-0.5v-1c0-0.275-0.224-0.5-0.5-0.5zM15.5 3h-11c-0.275 0-0.5 0.225-0.5 0.5v1c0 0.276 0.225 0.5 0.5 0.5h11c0.276 0 0.5-0.224 0.5-0.5v-1c0-0.275-0.224-0.5-0.5-0.5z"></path></svg></a> command, which lets you

Windows-style ones (CRLF) during file checkout (and the reverse when
