Hello, Nihat. I hope you are doing well. When I installed TensorFlow in the Zybo-Z7 I used the last compiled binary available for ARM 32-bits.
However, this binary creates an error when using the model.fit method that does not allow training the model.
If you want to use a machine learning framework in a Pynq-supported board with a 32-bit ARM processor, I would suggest using PyTorch (see
https://discuss.pynq.io/t/testing-pytorch-1-8-in-zybo-z7-running-pynq-2-7/4181).
Please let me know if this is useful.
Regards,
Dorfell
