Hello All, I have been trying to compile a tensorflow lite for microcontroller example in the Arduino Web Editor, but I got the following compilation issue: /home/builder/opt/libraries/latest/harvard_tinymlx_1_2_3_alpha/src/OV767X_TinyMLx.cpp: In member function 'int OV767X::begin(int, int, int, i…

Hi @gimmy987 . Which Arduino board are you compiling for (i.e., which board do you have selected from the menu on the Arduino Web Editor toolbar)?

@gimmy987 would it be possible for you to provide me with your model.h file? I tried to investigate but I'm not at all knowledgeable with Jupyter so it was slow going trying to generate the model just so I can compile the sketch. I think I got it all set up correctly, but I was dumb enough to do th…

Hi @ptillisch , thank you again for having a look at this issue. As requested, I attach the model.h to reproduce the issue in the Arduino Web Editor with Raspberry Pi Pico model.h (115.5 KB)

By the way, I compiled with Arduino Nano 33 BLE sense, and the sketch has been compiled correctly. I suspect that the issue may come from the Raspberry Pi Pico and some missing macro guards in the file where I got the compilation failure.? :thinking:

I'll start with the fix, then follow with "the boring details": The Fix Download the version of the "Arduino_TensorFlowLite" library that was created by Arduino from this link: https://downloads.arduino.cc/libraries/github.com/bcmi-labs/Arduino_TensorFlowLite-2.4.0-ALPHA.zip Wait for the download…

That was extremely helpful! I managed to fix my problem, and now I can use Arduino Nano 33 BLE Sense and Raspberry Pi Pico with the latest TFLite Micro. I used the Google Arduino library project. To make it work, I had to remove some Arduino Nano 33 BLE Sense dependencies in the peripherals. Withou…

[image] gimmy987: In particular, the following line does not allow to compile of the library for any Arduino boards except the Arduino Nano 33 BLE Sense: I also ran into that. It is really unfortunate the library maintainers allowed such a degradation to the flexibility of the library. I reve…

Hi gimmy, I need your help. Could you give me more details about how to fix the latest TFLite Micro for RPi Pico? I tried to remove the lines what you said but still don't work for me. Thanks for your support.

Hi @ajsoto89 ! More than happy! Did you download and upload this version of TFLu in the Arduino IDE? https://downloads.arduino.cc/libraries/github.com/bcmi-labs/Arduino_TensorFlowLite-2.4.0-ALPHA.zip I think, download that version is the simplest way to use TensorFlow Lite for Microcontrollers wit…
