Compile a TF Javascript model for Google Coral Edge TPU module

Question

I'd like to run a precompiled Google Teachable Machine TF Javascript model on a Raspberry Pi with an USB Google Coral Edge TPU module.

I've compiled a Colab Notebook (this). It compiles all the way through to the TFlite Edgetpu format.

Now when I try to run it with the adequate script (this) I get the following error:

File "classify_image.py", line 76, in main raise ValueError('Only support uint8 input type.') ValueError: Only support uint8 input type.

Anybody any idea on how to fix this?
