<p>We just saw a bug in Telescope where YAPF changed out from under us and started causing build breaks.</p>

<p><a href="https://github.com/m-lab/telescope/issues/76" class="issue-link" title="Fix travis config to tie YAPF to a specific version">m-lab/telescope#76</a></p>

<p>Fortunately YAPF v0.4.0 and v0.5.0 format Observatory exactly the same, but we should fix the version so that we're using an explicit version of YAPF.</p>
