Same here.
I’ve installed Tensorflow as per the Apple docs:
  
      

      Apple Developer
  

  
    

Tensorflow Plugin - Metal - Apple Developer 4

  Find presentations, documentation, sample code, and resources for building macOS, iOS, and tvOS apps with the Metal framework.


  

  
    
    
  

  


and then tried to install tflite-model-maker and get the same issue as the OP. If I edit requirements.txt to change the dependency to tensorflow-macos instead of tensorflow, I get an error with tflite-support.
Is there a working guide on how to install tflite-model-maker on a M1 Macbook? I’m not too bothered about using the M1 neural capabilities just yet.
