@BenjaminDannegard can you take a look at the comments from Per and test it out and adjust the content?

The IMU Classifier sketch at the end of the tutorial fails to compile when using the updated library version:

C:\Users\per\Documents\Arduino\IMUClassifier\IMUClassifier.ino:23:10: fatal error: tensorflow/lite/version.h: No such file or directory
 #include <tensorflow/lite/version.h>
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

exit status 1

Compilation error: tensorflow/lite/version.h: No such file or directory

As you can see, the library does not contain this file:

https://github.com/tensorflow/tflite-micro-arduino-examples/tree/4056e5f13aafb4dd3eda46cec273133a1d5e9593/src/tensorflow/lite

I also found there is a problem with the "Setup Python Environment" step of the Jupyter notebook:

@per1234 could we get in contact with the Tensorflow people and ask them if they can take a look at the library issue and fix it on their end? Do you know anyone over there we could talk to about this?

Hi @BenjaminDannegard. I don't know anyone involved with the TensorFlow project. I only received the library removal request from them as part of my duties maintaining the Arduino Library Manager index as a whole.

@BenjaminDannegard can you make a copy of the now incorrect example, and then remove it from the article for now? Like we discussed earlier.

@BenjaminDannegard I manually added in version.h which I got from here: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/public/version.h

and my project compiled. if you're looking for some quick and dirty fix this may work for you.
