Tensorflow on macOS Apple M1 - macos

Question

I am trying to install tensor flow on my macOS M1.
As per chip compatibility I know that not all the pip images of tensor flow works or are even compatible. But I found this repository
https://github.com/apple/tensorflow_macos
Which is supposed to be working on Apple M1.
After the installation, I downgraded my python to version 3.8 and start the installation, everything went just fine without any issue.
just for testing purpose, I found this script online.

Failed to load the native TensorFlow runtime.
See https://www.tensorflow.org/install/errors
for some common reasons and solutions. Include the entire stack trace
above this error message when asking for help.
The error is about the architecture but I have no idea how to fix. Did anyone found a solution to this problem?
Thank you so much for any help you can provide.

Things should work better now.
As of Oct. 25, 2021 macOS 12 Monterey is generally available.
Upgrade your machine to Monterey or newer OS if you haven't already.
If you have conda installed, I would probably uninstall it. You can have multiple conda versions installed but things can get tricky.
Then follow the instructions from Apple here. I cleaned them up a bit below:
Download and install Conda from Miniforge:
chmod +x ~/Downloads/Miniforge3-MacOSX-arm64.sh
sh ~/Downloads/Miniforge3-MacOSX-arm64.sh
source ~/miniforge3/bin/activate
In an active conda environment, install the TensorFlow dependencies, base TensorFlow, and TensorFlow metal:
conda install -c apple tensorflow-deps
pip install tensorflow-macos
pip install tensorflow-metal
You should be good to go with fast training speeds.
