Tensorflow Lite for Teensy 4

[randomvibe]

Given T4's clock speed and inference benchmarks, I'm surprised teensy did not make the "supported platforms" list:

https://www.tensorflow.org/lite/microcontrollers

Machine learning and inferencing on a microcontroller is an important subject and hugely relevant. It's here to stay. Any plans on adding a T4 friendly version of Tensorflow Lite in the teensyduino webpage with a solid example?

You might want to take a look at <this> forum thread (& there are others . . . just search for "tensorflow").

I did look at your reference plus many others prior to starting this thread. The @andrewpiepenbrink thread says "...it was a rough experience; lots of thrashing around with Makefiles, spurious clobbered newlines, and other evils..." Thought I'd check with PJRC first to see if a worked out TFLite library is in the works. I think the user community would love to see it the PJRC Library page that works out of the box.

It goes without saying that Machine Learning is a major field. One of TFLite's supported platforms is the Arduino-Nano-33-BL, and it's SOLD OUT in sparkfun and the arduino shop. I'd rather buy and try it on Teensy 4. The benchmarks out there show it's the fastest.

You might try this on the T4: https://github.com/mjs513/Arduino_TensorFlowLite_t4, it can confirm it works on a Teensy Micromod - should work on the T4 as well. May have to adjust the examples if you test with video.

Wow - the original over 2 years ago when that was tried ... and remember trying to get my CAT id'd on the T_MM with camera.

Also one reason might be the TF.org link led to github.com/tensorflow/tflite-micro/blob/main/LICENSE that is "Apache-2.0 License" where prefers MIT for inclusion and support - plus way too much else taking time those past years.
