<p dir="auto">I am building my codes with tensorflow_lite_gpu.framework on iPhone 7. The codes is just like Google recommends:</p>

<p dir="auto">When I use the model mobilenet_v1_1.0_224.tflite which Google provides, I get warning: <code class="notranslate">WARNING: 25 cannot be handled by this delegate.  Only the first 30 ops will run on the GPU, and the remaining 1 on the CPU</code> from console after excuting <code class="notranslate">_interpreter-&gt;ModifyGraphWithDelegate(_delegate)</code>. But the model deeplabv3_257_mv_gpu.tflite is good which Google provides too. As for my own model, the result is like mobilenet_v1_1.0_224.tflite does. Someone please help me.</p>
