FYI, tf-nightly 2.15.0.dev20230817 picked up the required fix. Not sure if anyone has raised a PR to re-enable the tflite tests.

[hanhanW]

@jpienaar I've seen you bumped tf-nightly couple times, could you help bump tf-nightly version and re-enable the tests and benchmarks?

[jpienaar]

@rsuderman is already working on this AFAIK

[hanhanW]

Hey @rsuderman I'd like check in what's the status about this? I have a couple PRs that needs to test if there are regression. It would be awesome if this is prioritized.

I'm trying to bump it. It looks like we need to bump python to 3.9 as well.
