title: Unable to convert YOLOv4 to tflite
body: <p>I'm trying to use <code>yolo4</code> in my android project but I'm having problems with conversion.
  The code from: <a href="https://pypi.org/project/yolov4/" rel="nofollow noreferrer">https://pypi.org/project/yolov4/</a> has worked well on <code>Google-Colab</code>, though it had some problem with my <code>CUDA</code> version on <code>Jupyter</code> notebook.</p>
  <p>I got conversion error from:</p>
  <pre class="lang-py prettyprint-override"><code>yolo.save_as_tflite(&quot;yolov4.tflite&quot;)
  </code></pre>
  <p>Error was long and I am not sure which part I should paste here.</p>
  <p>Can someone recommend some alternative method to convert <code>tflite</code> version of yolo4 (preferably working on <code>colab</code>)?</p>
