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.

Inizia con il comando del notebook Google Colab ML che genera model.h e con lo sketch Arduino che segnala l’avviso di allineamento di tensor_arena. Riproduci la build per il riconoscimento dei gesti e l’output seriale, quindi verifica che l’header del modello generato sia allineato correttamente e che i gesti vengano classificati senza l’avviso.

Scritto dal modello di indicizzazione a partire dal testo della issue.
