hello, sorry if this has been asked before
i’m trying to use libraries from tensorflow followed by this article
https://towardsdatascience.com/tensorflow-meet-the-esp32-3ac36d7f32c7

there’s some slight modification to the steps since the new tensorflow lite is no longer an experimental

i moved all the libs from the compilation to the “lib” folder in the project you can see the structure below

Libs
Libs226×576 6.06 KB

and after doing that i tried to include the libs but it doesn’t recognized by the IDE
libs2
i tried to compile it anyway but i got error saying “no such file or dirrectory”

did i placed the libs incorrectly ?
i changed the lib_ldf_mode = deep still didnt fix it

English is not my main language sorry if there’s some part you didn’t understand, really apreciate help from this community thankyou

Their sample project is up at GitHub - wezleysherman/ESP32-TensorFlow-Lite-Sample: Sample project for deploying TensorFlow Lite models on the ESP32 using Platformio and you can look at the folder structure there. It’s different to yours since it has lib/tfmicro/tensorflow/lite in it, but you’re doing lib/tensorflow/lite/micro.

i make some adjustment according to the GitHub Page turns out the problem is because i didn’t include the

libs_deps = tfmicro

in platformio.ini

the dependency is now fixed but i got another problem, i think it has to do with the toolchain the error
the code looks like this

Code_aK35jFT9qR

the problem

Code_IzKtLV12QZ

and the compile log

Code_IyAaV704DM
Code_IyAaV704DM1149×298 45 KB

tried to change the “include” with
#include <tgmath.h>
i get more errors instead

So have you just tried enabling the other codepath and use std::max instead of std::fmax. Because that at least auto-completes for me in the ESP32 environment.

Adding something like || defined(ARDUINO) would suffice in the #if defined check expresson. Or ARDUINO_ARCH_ESP32 if you want to be precise and limiting to ESP32-Arduino.

Same for fmin().

adding the defined(arduino) fixed the problem for me thankyou
