Error compiling for Teensy 4.1

[SebyR]

Hello, when I verify the code with the Teensy 4.1 board selected I get the following error: In file included from c:\Users\Sebi\Documents\Arduino\libraries\EloquentTinyML\src\eloquent_tinyml\tensorflow\arm\tensorflow\lite\micro\micro_utils.cpp:17: c:\Users\Sebi\Documents\Arduino\libraries\EloquentTinyML\src/eloquent_tinyml/tensorflow/arm/tensorflow/lite/micro/micro_utils.h: In function 'T tflite::FloatToQuantizedType(float, float, int)': c:\Users\Sebi\Documents\Arduino\libraries\EloquentTinyML\src/eloquent_tinyml/tensorflow/arm/tensorflow/lite/micro/micro_utils.h:39:42: error: 'numeric_limits' is not a member of 'std' 39 | std::max(static_cast(std::numeric_limits::min()), result); | ^~~~~~ c:\Users\Sebi\Documents\Arduino\libraries\EloquentTinyML\src/eloquent_tinyml/tensorflow/arm/tensorflow/lite/micro/micro_utils.h:39:58: error: expected primary-expression before '>' token 39 | std::max(static_cast(std::numeric_limits::min()), result); | ^ c:\Users\Sebi\Documents\Arduino\libraries\EloquentTinyML\src/eloquent_tinyml/tensorflow/arm/tensorflow/lite/micro/micro_utils.h:39:61: error: '::min' has not been declared; did you mean 'std::min'?

Just compile with the flag -D TF_LITE_USE_GLOBAL_MIN set

Just compile with the flag -D TF_LITE_USE_GLOBAL_MIN set

Where should I insert the flag? P.S I am also Romanian but i will write in English

How do you compile the files more exactly? If you just do it from Arduino IDE, better do this inside min.h and max.h files:

if defined(TF_LITE_USE_GLOBALMIN) || defined(ZEPHYR) || defined(ARDUINO)_

if defined(TF_LITE_USE_GLOBALMAX) || defined(ZEPHYR) || defined(ARDUINO)_

I think the latest TF package has updated the code as above.

I am using Arduino IDE. I modified the eloquent library where you sugested but no succes, it still shows the same error.

[vladBaciu]

Try to add in micro_utils.h #include <limits>

I don't use the Teensy board (although I have one). Do you use Arduino IDE or Teensyduino IDE?

Sorry for the late answer, I had a lot of schoolwork to do. I am using Arduino IDE with a Teensy 4.1 board. It was a problem with only the 2.4.0 library. When I used one of the older libraries it worked. Now I will try to use the 3.0.1 library, but I will remake the training because the model (the one that I used with the 2.4.0 library) isn't compatible anymore.
