zsh: illegal hardware instruction python when Installing TensorFlow for M1

[MalteSil]

I've followed these steps :

• install a venv: python3 -m venv venv.
• drag the install_venv.sh (which is located within the downloaded folder) file to the terminal, add -p at the end.
• select the directory of the venv as the location where tensorflow should be installed.
• activate the venv.
• type "python".
• try to import tensorflow: import tensorflow as tf.

I'm using Python 3.8 and I'm running my terminal not rosetta:
(base) user@useros ~ % uname -m
arm64
When I activate my environment I still get:
(venv) (base) user@useros ~ % uname -m
arm64

If I run file $(which python) I get the following:
On base:
(base) user@useros ~ % file $(which python)
/Users/user/opt/anaconda3/bin/python: Mach-O 64-bit executable x86_64

On venv:
(venv) (base) user@useros ~ % file $(which python)
/Users/user/venv/bin/python: Mach-O 64-bit executable x86_64

Why do I get 'Mach-O 64-bit executable x86_64' here even though I get 'arm64' before?
This confuses me and is probably the reason why my code is not working.

So, I got it working yesterday after a long time of similar problems.
What helped me was the following:

1. Use the python 3.8 version that was preinstalled by Apple, which should be python 3.8.2.
2. Deactivate conda conda deactivate
3. Create new virtualenv by python3 -m venv .venv
4. Change all files in tensorflow_macos/arm64 from *_11_0_*.whl to *_10_16_*.whl
5. Change all filenames in install_venv.sh to *_10_16*.whl
6. Run install_venv.sh

Then it should work! I hope that helps!

Edit: I just forked the repo and added my own instructions on how to properly install it for future reference. Maybe that will help you more: https://github.com/andy-96/tensorflow_macos

Thank you! My Conda environment was indeed active, will try it later.
What is the reason behind changing the files and filenames?

Tbh, I don't know...

Python3 is shipped with 2 architectures in M1.

$ file $(which python3)
/usr/bin/python3: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64e:Mach-O 64-bit executable arm64e]
/usr/bin/python3 (for architecture x86_64):	Mach-O 64-bit executable x86_64
/usr/bin/python3 (for architecture arm64e):	Mach-O 64-bit executable arm64e

Here, you might need to specify which one to use. You can do this by installing the script like this:

arch -arm64 bash install_venv.sh my_tf_env

if you have multiple python installations, use:

arch -arm64 bash install_venv.sh --python=/usr/bin/python3 my_tf_env

You can replace my_tf_env with any other name/path you choose.

@Alyetama is right, I got this issue fixed in my repo, just make sure you have installed Xcode (download the latest version and install it): https://developer.apple.com/download/more/?=command%20line%20tools

Then in a terminal paste
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/chinitaberrio/tensorflow_macos/master/scripts/download_and_install.sh)"
That should fix the issue :)

uninstalling tensorflow worked for me

You can install all the following modules by creating a Virtual Environment, and then installing all these modules inside that Virtual Environment.

1. Install Matplotlib

1.1 Install Homebrew
Type in your terminal (not in rosetta environment):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Then add homebrew's path to the variable path:

echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/bcghostpc/.zprofile eval $(/opt/homebrew/bin/brew shellenv)

1.2 Install libjpeg

brew install libjpeg

1.3 Install Matplotlib

In the virtual environment, type:

pip install matplotlib

2. Install tensorflow

Type in terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/apple/tensorflow_macos/master/scripts/download_and_install.sh)"
then name your virtual environment's folder

3. Install pandas

In your virtual environment, type:

pip install cython
git clone https://github.com/pandas-dev/pandas.git
cd pandas
python3 setup.py install

4. Install jupyter notebook

In your virtual environment, type:

pip install notebook
Then go to lib/python3.8/site-packages/ipykernel

Edit the eventloops.py file using nano eventloops.py

In the _use_appnope() function, edit the return line as follows:

return sys.platform == 'darwin' and V(platform.mac_ver()[0]) >= V('10.9') and platform.mac_ver()[2] != 'arm64'

Appendix

About Installing Different Modules
You can install any module using pip inside Virtual Environment:

pip install <moduleName>

About Virtual Environment

You can create a virtual environment by:

python3 -m venv <name>
After creating the environment, you can activate the environment by:

source <name>/bin/activate
To exit the environment, type:

deactivate

I'll give that a shot.

There might also be a fix by upgrading to this tensorflow alpha, but I haven't trie dit because it requires that I down grade to 3.8 of python.
