title: How to suppress all autograph warnings from Tensorflow?
body: <p>I'm getting a warning which I cannot find a solution to.
  Apparently this:</p>
  <pre class="lang-py prettyprint-override"><code>import os
  os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'  # or any {'0', '1', '2'}
  import tensorflow as tf
  os.environ['AUTOGRAPH_VERBOSITY'] = '1'
  </code></pre>
  <p>is not enough to stop this annoying message:</p>
  <pre class="lang-py prettyprint-override"><code>WARNING:tensorflow:AutoGraph could not transform &lt;function Model.make_train_function.&lt;locals&gt;.train_function at 0x00000281A55264C8&gt; and will run it as-is.
  Please report this to the TensorFlow team. When filing the bug, set the verbosity to 10 (on Linux, `export AUTOGRAPH_VERBOSITY=10`) and attach the full output.
  Cause: Bad argument number for Name: 4, expecting 3
  To silence this warning, decorate the function with @tf.autograph.experimental.do_not_convert
  </code></pre>
  <p>which pops up after every single epoch.</p>
  <p>And yes, I've decorated every function I have with <code>@tf.autograph.experimental.do_not_convert</code> and the message still pops up. I am currently using Tensorflow 2.2.0</p>
  <p>If you know the reason why this is happening, that would be great. I have no clue what &quot;Name&quot; is, as nothing is called that anywhere in any of my files.</p>
