error while Inputting image in tensorflow input to do classification with tflite micro

[sisimonis 5 1 1]

Hello,

I'm currently using a tflite micro model on arduino to make animals classification with image of size 2242243.

After taking photo, i converted it to rgb to have usable pixels. I am trying to put these pixels in the input tensor of the interpreter.

The input tensor is pretty large (150k) and when i reach the ~ 120kth, i'm facing this error :

I think it's a stack size problem because when i just take one by one the input, there is no problem, but in a loop, i have this.

If you have any idea, that could help a lot !

Thanks

Hey, @sisimonis-5-1-1
Here is a forum post that teaches you how to change stack size using the CLI:

https://forum.developer.sony.com/topic/624/error-in-running-tflite-program/3

Try using 8192 for stack size.
