So I finally merged this longstanding tensorflow-lite series.
Thanks again!

The version merged here is a bit outdated already. See:
https://github.com/tensorflow/tensorflow/releases/tag/v2.11.0
from November 2022.

For reference, the latest version, as of today is v2.18.0:
https://github.com/tensorflow/tensorflow/releases/tag/v2.18.0
from October 2024.

So it would be really nice to see updates towards this newer version.
This will probably bring new dependencies too.

Also, for information, tensorflow-lite is in a process to be
renamed to LiteRT. See:
https://developers.googleblog.com/en/tensorflow-lite-is-now-litert/
https://github.com/google-ai-edge/litert

It seems this process will take some time, so I merged this
package with its "old" name anyway.

Best regards,

Julien.

Yeah, now that it's merged it should be a bit easier to bring up to
date, with so many new dependencies even for the older version
I wanted to try and keep the series as small as possible.

Yeah, it seems changes are getting pushed to the old and new
locations still.
