I was trying to follow this tutorial and ran into a problem compiling on the Arduino IDE with an ESP32 board. https://eloquentarduino.github.io/2019/12/how-to-do-gesture-identification-on-arduino/
I end up getting multiple lines of error from Arduino saying:
Error: operand 2 of 'l32r' has out of range value '4294704916'
The code that its struggling to compile is the converted SVM model generated from SciPy. The file is very long, but here is a snippet of what it looks like:
#include "model.h"
#include <cstdarg>
int SVM::predict(float *x) {
float kernels[92] = { 0 };
float decisions[21] = { 0 };
int votes[7] = { 0 };
kernels[0] = compute_kernel(x, 1.2 , -1.79 , -1.1 , 1.22 , -1.36 , 0.26 , 1.0 , -1.57 , -0.81 , 1.08 , -1.45 , -0.18 , 1.18 , -1.77 , -0.31 , 1.59 , -1.69 , 0.55 , 6.74 , 0.71 , -13.06 , 6.31 , 12.0 , -4.34 , 1.55 , -0.16 , 0.0 , 1.38 , 1.91 , 1.02 , 0.96 , -2.28 , -0.45 , 1.3 , -2.12 , -0.49 , 0.83 , -0.18 , -0.79 , 0.92 , -0.73 , 1.34 , 2.59 , -4.15 , -3.4 , 2.22 , -0.2 , 1.41 , 0.61 , -3.91 , -1.39 , 9.29 , 1.85 , -16.0 , 2.4 , -1.02 , -0.75 , 1.87 , 0.18 , 0.47 , 1.38 , -2.06 , 0.06 , 1.32 , -2.16 , 0.1 , 1.63 , -2.2 , -0.16 , 1.47 , -1.49 , -0.08 , 0.98 , -1.51 , -0.55 , 1.3 , -1.53 , -0.12 , 1.32 , -1.61 , -0.47 , 1.18 , -1.26 , -0.2 , 1.43 , -1.06 , 0.06 , 1.3 , -1.18 , -0.59 , 0.94 , -0.1 , 1.04 , 1.28 , -1.41 , -0.55 , 1.26 , -1.3 , -0.18 , 1.28 , -1.65 , -0.39 , 1.26 , -1.36 , 0.63 , 1.45 , -1.45 , -0.57 , 1.65 , -1.32 , -0.63 , 1.3 , -1.28 , -0.35 , 1.22 , -1.3 , -0.31 , 1.22 , -1.02 , 0.16 , 1.12 , -1.43 , -0.39 , 1.1 , -0.96 , 0.43 , 0.92 , -1.12 , -0.37 , 1.24 , -0.86 , 0.0 , 1.1 , -1.12 , -0.24 , 1.12 , -1.34 , -0.2 , 1.16 , -1.14 , -0.1 , 1.14 , -1.12 , -0.24 , 1.24 , -1.1 , -0.26 , 1.16 , -1.39 , -0.24 );

//and so on
decisions[0] = 1.245222806707
+ kernels[1] * 0.00090445776
+ kernels[2] * 0.000488112628
+ kernels[8] * 0.000123322494
//and so on
I have the following flags enabled on the compiler:
compiler.c.extra_flags=-mlongcalls -mtext-section-literals
It just won't compile for some reason and gives me the same l32r message. Can someone please help? Much is appreciated.
