Installing Tensorflow on macOS on an Arm MBP

When attempting to install tensorflow on an ARM M1 MacBookPro, I am seeing the following issues:

% pip install tensorflow
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow

After searching around, I found a package called tensorflow-macos which produces the following issues:

Unfortunately I couldn't work out a solution to the 'faltivec' issue. I also found a tensorflow package made by Apple that seems specifically geared for M1's, however going by this tutorial produces the following issues:

% pip install --upgrade --force --no-dependencies https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_addons_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl
ERROR: tensorflow_addons_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl is not a supported wheel on this platform.

After this, I am a bit stuck. I have upgraded pip to 21.1.3, and my python version is Python 3.9.6.

Tensorflow-macos and Tensorflow-metal Install

Currently, to harness the M1 GPU you need to install Tensorflow-macos and TensorFlow-metal as opposed to Tensorflow, the install steps are detailed here, they can be summarized as follows using mini-forge:

conda create -n tf python=3.8 -y
conda activate tf
conda install -c apple tensorflow-deps -y
# Navigate the issue with conda environments
# built against pre-macOS 11 SDK use (Just in case)
# this solves the Intel / M1 install issues:
SYSTEM_VERSION_COMPAT=0 pip install tensorflow-macos 
SYSTEM_VERSION_COMPAT=0 pip install tensorflow-metal

to test all is well we can run:

#!/usr/bin/env bash

PYCMD=$(cat <<EOF
import tensorflow as tf

tf.config.list_physical_devices()
with tf.device('/GPU'):
  a = tf.random.normal(shape=(2,), dtype=tf.float32)
  b = tf.nn.relu(a)

print(a)
print(b)

EOF
)

python3 -c "$PYCMD" 2>/dev/null

the expected output for my test machine:

>./val.sh
Metal device set to: Apple M1

systemMemory: 16.00 GB
maxCacheSize: 5.33 GB

tf.Tensor([-0.4044231   0.08157467], shape=(2,), dtype=float32)
tf.Tensor([0.         0.08157467], shape=(2,), dtype=float32)

ok, everything is (assumed) to be working...

Side-Note: Package Install Issues:

One thing to note is that that packages that rely on tensorflow will try to install tensorflow as they will likely not have an explicit dependency on tensorflow-macos or tensorflow-metal.

When you install tensorflow dependent packages or code you'll likely have to review the requirements.txt file before running:

python3 pip install -r requirements.txt

The requirements.txt will try to install the tensorflow package, not the tensorflow-macosx or tensorflow-metal packages which will result in a host of issues if you run the requirements.txt file unchanged. That and explicit versions of packages == which can also cause problems.

Hopefully, this points you in the right direction in thinking about the hurdles involved in getting python to work with the Apple-M1 laptops using the TensorFlow metal plugin to harness the M1 GPU features.

Stay safe and well.
