Tensorflow on Artik710

[ogeraisi]

Hello,

Up until now I've been running Tensorflow 1.8.0 on a board with Artik710 (AARCH64) using the pre-compiled wheel in the releases section (Python 3.5.2, Ubuntu 16.04).

When trying to upgrade to 1.14 or newer (2.2.0 / 2.3.0) I get "Illegal Instruction" when trying to load the pb model I have trained.
I was wondering if you would have any idea to what causes that? If maybe something has changed in the build process that might have caused it.

I tried running the same code / model with Tensorflow 1.8.0, 1.12.0 and 1.14.0, it worked on the first two but not on the latter.
Is it maybe something that was changed in the config in that specific release or what could be causing this issue?
