I did finally get it to install, with any of 3.9, 3.10, or 3.11 with the following sequence
conda create --name raft python=3.10
conda activate raft
python -m pip install -U pip
conda install -c apple tensorflow-deps
python -m pip install tensorflow
python -m pip install tensorflow-metal
[also tried forcing version 2.15.1)
But I get this error when I try to import tensorflow
import tensorflow as tf
