Convert model to tflite

I’m trying to convert one of those models to tflite ( all those models are related to Naruto Hand Sign detection )

I’m beginning so sorry if I’m asking stupid questions !!!

my understanding is that after converting to tflite the expected result should be one of 12 classes ( bird, boar, dog, dragon, hare, horse,monkey,ox,ram,rat, snake, tiger) with score :

Like :bird : 0.99 % or dragon : 0.80 % …

but as output I have array [[0. 0. 1. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0.]] for any input image !

Please can someone help how I can convert correctly one of those model to tflite with example of python code that take image as input and return correct result like ( dragon=0.95, boar=0.0, dog=0.0, dragon=0.0, hare=0.0, horse=0.0,monkey=0.0,ox=0.0,ram=0.0,rat=0.0, snake=0.0, tiger=0.0)

input image can be something like this :

or any image from :
