xx bytes lost due to alignment. To avoid this loss, please make sure the tensor_arena is 16 bytes aligned

I get this error message I get when I basically replicate the gesture recognition tutorial in [Arduino ML guide](https://blog.arduino.cc/2019/10/15/get-started-with-machine-learning-on-arduino/).

More importantly, though the arduino sketch builds, the model doesn't appear to be working, since the serial output doesn't report any gestures.

The workaround that worked for me was to change the header in the model.h encoding in the Google Colab ML notebook:

Original: !echo "const unsigned char model[] = {"

What worked for me: !echo "alignas(8)const unsigned char model[] = {"

The addition of alignas(8) fixed the issue in that the arduino sketch build is now working, and I am able to classify gestures.

Beginne mit dem Google Colab ML-Notebook-Befehl, der model.h generiert, und dem Arduino-Sketch, der die tensor_arena-Ausrichtungswarnung meldet. Reproduziere den Build zur Gestenerkennung und die serielle Ausgabe. Überprüfe anschließend, dass der generierte Modell-Header korrekt ausgerichtet ist und Gesten ohne die Warnung klassifiziert werden.

Vom Indexierungsmodell aus dem Issue-Text verfasst.
