You can train any model with <code>model.train()</code> and <code>model.predict()</code>.</p><h2 class="anchor anchorWithStickyNavbar_mojV" id="prepare-python-environment-to-run-submarine-sdk">Prepare Python Environment to run Submarine SDK<a class="hash-link" href="#prepare-python-environment-to-run-submarine-sdk" title="Direct link to heading">β</a></h2><p>Submarine SDK requires Python3.7+. |
