intermediate tensors allocated by <code>fn</code> except those returned by <code>fn</code>.
<code>fn</code> must not return a Promise (async functions not allowed). The returned
result can be a complex object.</p>
<p>Using this method helps avoid memory leaks. In general, wrap calls to
operations in <code>tf.tidy</code> for automatic memory cleanup.</p>
<p>NOTE: Variables do <em>not</em> get cleaned up when inside a tidy(). If you want to
dispose variables, please use <code>tf.disposeVariables</code> or call dispose()
directly on variables.</p>
