Support running on M1 Macs [Python] #915

FabianBruengerPexon · 2021-02-16T20:39:55Z

Hey,

i am running into issues with python azure function under VSCode. FYI the same example I will present is working fine with JS.

Set up:
Mac M1 Big Sur v11.2.1
python 3.9.1
Core Tools Version: 3.0.3284

I am following the usual workflow: func init, func new, func start. When I start the function, this is what I get:

Found Python version 3.9.1 (python3).

I would appreciate some advice here!

anthonychu · 2021-10-30T07:09:06Z

Looks like Core Tools is able to run in x64 emulation but it’s starting the python worker in ARM. The worker uses x64 binaries in some places and that’s where it appears to be failing. Are you able to run the entire stack with x64 emulation? I only have an Intel Mac so I can’t try this out.

/cc @vrdmr

anthonychu · 2021-10-30T07:13:58Z

For Node.js we were able to fix this by using a pure JS implementation of gRPC that doesn’t rely on platform specific binaries.
Not sure if same exists for Python. Azure/azure-functions-nodejs-worker#386

simon-tarr · 2021-11-02T18:07:16Z

Unable to test this at present but (thinking out loud here): I'm wondering if running everything in a conda environment of some description would help in the interim? Using conda environments has solved a ton of (unrelated) problems for me over the past few months while x86 and arm64 code is living side by side.

This was a good hint, thank you! I was able to start func start host without an error on my M1 Macbook Pro.

What have I done?

Enable Rosetta in iTerm so that you get the following output:

$ arch
i386

install the intel homebrew with:

$ arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

refer to https://stackoverflow.com/questions/64882584/how-to-run-the-homebrew-installer-under-rosetta-2-on-m1-macbook
3. install azure-functions-core-tools@4 and python in this homebrew
4. setting python path to the rosetta python
5. run the command:

$ arch -x86_64 /usr/local/bin/func start host

ejizba · 2021-11-18T19:29:29Z

Cleaning up M1 Mac issues at the moment. This one seemed like the most detailed Python issue, so I've transferred it here to track any Python-specific work. Main core tools issue is here: Azure/azure-functions-core-tools#2834

Also this comment from @vrdmr seems particularly relevant: Azure/azure-functions-core-tools#2394 (comment)

Fyi @vrdmr I've created an arm64 build of core tools and I now see this error when running on an M1 Mac:

Failed to initialize worker provider for: /Users/erijiz/tools/func-arm/workers/python
Microsoft.Azure.WebJobs.Script: Architecture Arm64 is not supported for language python.

I believe that's because Arm64 is not listed in the worker config here. Let me know when you have an arm64 build of the worker and I'd be happy to test for you.

felixnext · 2022-03-21T08:32:26Z

Running into the same issue as @ericdwkim. Also noted that this works with python 3.8 environments, but not with python 3.9. Is there an ETA for the fix @ejizba?

yugyesh · 2022-03-23T08:18:58Z

The best work around I have found is to use python interpreter installed in conda environment

1. Create a conda environment with supported python version

2. Go to the root directory of the project

3. Remove .venv folder

4. Activate the newly created conda environment

5. Create new virtual environment using `python -m venv .venv/`

kentongray · 2022-04-11T21:15:27Z

For the wary traveller, I have tried a bunch of these without success and wasn't willing to switch to x86, this trick, while maybe bad practice, worked for me (basically copying over the binary):

Any updates on this? Silver lining is it's forced me to write more testing harnesses 😬 , but it's getting a little tricky to troubleshoot in some scenarios..

shreyabatra4 · 2022-05-12T19:16:07Z

Hi, this issue should be resolved with the release of support for Python 3.10 in Functions, which is planned for end of May.

kijewskimateusz · 2022-06-05T11:06:41Z

Hi @shreyabatra4 Do you maybe have any info on estimated release date for Function App Python3.10 support?

^I have the same question

kijewskimateusz · 2022-06-07T17:09:37Z

@danielw1534 In the meantime you can try this workaround

BadrElfarri · 2022-06-10T07:44:30Z

Is this fixed? non of the workaround works for me

iPypeNB · 2023-10-31T14:19:06Z

I do not want to sound hater, but seriously I have not known functionality that has had so many delays, it is incredible that since 2021 is promising that this functionality will come out and nothing. It already seems to me a lack of respect to all users that they have decided not to respond so as not to continue to look bad. please report what is happening with this new release?

shreyabatra4 · 2023-11-09T19:45:38Z

Hi everyone - thank you again for all your patience with this release! I empathize with your comments on the multiple delays of this release, and we really appreciate your understanding and feedback.

I do have some good news - support for ARM 64 is now released! Please upgrade to the newest Core Tools (4.0.5455) to try it out.

I will close this issue out alongside our official announcement for this feature! Please comment and let us know if you have any feedback when trying it out.

himanshu-ram-punjabi · 2023-11-09T20:17:00Z

Thank you for the update, Shreya. I look forward to the official documentation to try this on the MacBook.

dzsquared · 2023-11-09T20:28:17Z

available in brew, thanks @shreyabatra4!

Yurockkk · 2023-11-10T20:22:48Z

Worked like a charm, all I need to do is to upgrade to the latest version of azure-functions-core-tool. thanks @shreyabatra4!

lucasfijen · 2023-11-14T10:45:28Z

Thank you for releasing this @shreyabatra4!
I'm still running into some issues when trying to get this version installed on a devcontainer on a mac:
E: Unable to locate package azure-functions-core-tools-4
Could it be that the azure function is not released in the packages to ARM64 folder?
When checking the packages in https://packages.microsoft.com/debian/11/prod/dists/bullseye/main/binary-arm64/ I don't see any azure-functions-core-tools mentioned, while the https://packages.microsoft.com/debian/11/prod/dists/bullseye/main/binary-amd64/ Does contain the latest version.

Are these supposed to be there, or am I asking something impossible here?

Works like a charm for me. Thanks so much!

r-findley · 2023-11-14T18:25:04Z

The new solution worked (mostly) great for me. Has anyone gotten the warning "Customer packages not in sys path. This should never happen!" when running the func start command? I get this from any Azure Function project, both ones that I have created a new environment for since the update and those from prior to the update. I do not, however, get this on any other Python project on my computer, suggesting this could be related to the Core Tools.

vrdmr · 2023-11-14T18:56:47Z

@lucasfijen - For your issue - are you installing core tools inside docker running on your Mac?

Install script used in docker building script which works on a amd64 computer, but not on a arm64 macbook:

@r-findley - This is an issue that we caused due to incorrect logging, and the fix (#1335 from @hallvictoria) will be part of the next release of the Functions (host + core tools). Please ignore this log for the time being - it is a red herring.

vrdmr · 2023-11-14T18:59:40Z

Closing this issue - Apologies for the delay, and we will work towards ensuring faster releases and getting them out sooner.

Thanks a lot for continuing to use Python Functions and we'd love to hear your feedback on M1 and other features.

@vrdmr

@lucasfijen - For your issue - are you installing core tools inside docker running on your Mac?

I'm trying to install it indeed at the building scripts of my devcontainer.

I tried this in 2 ways, either with:
the feature "ghcr.io/jlaundry/devcontainer-features/azure-functions-core-tools:1": "latest", in devcontainer.json,

or with a postcreatecommand in which I added:

DEBIAN_VERSION=11

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget -q https://packages.microsoft.com/config/debian/$DEBIAN_VERSION/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list

sudo apt-get update
sudo apt-get install azure-functions-core-tools-4

Both return the same unable to locate azure-functions-core-tools.

I think the issue is that brew is not available in a debian based devcontainer, but as for the links in my previous command, the arm64 based debian packages are not published where these methods will be searching.

I can confirm I no longer need to use emulation and an "arch -x86_64" version of homebrew to run func core tools on apple silicon. Thanks for implementing this.

krutilins · 2024-02-23T23:21:12Z

It would be helpful to publish the arm64 version to Debian packages, if that's possible :)

Currently, we must use emulation to run Debian-based devcontainer

I could successfully run "func start" with .venv. But couldn't run it with conda environment.

python -m venv .venv
source .venv/bin/activate
pip3 install virtualenv
.venv/bin/python -m pip install --upgrade pip
pip install -r requirements.txt

I still see the issue with apple 4.0.5907

jan-ri · 2024-07-16T13:36:04Z

Same for me, getting errors with version 4.0.5907 on M2 using Python 3.11.9.

shreyabatra4 · 2024-07-16T15:05:39Z

@yogeshg and @jan-ri Can you please provide the error messages you are seeing?

jan-ri · 2024-07-16T17:10:07Z

Okay nvm... Seems to be a problem after an update. I've done a reinstall in Homebrew at first, which didn't solve the problem. After I performed an uninstall and then install to get a clean reinstall it worked perfectly fine.

Having the same issue on M2 Pro python3.10 and core tools 4.0.5907

ramiayoub-priv · 2024-08-14T13:03:45Z

As a workaround you can install grpcio using pip in your venv and the copy the whole directory .venv/lib/python3./site-packages/grpc/ to /opt/homebrew/Cellar/azure-functions-core-tools@4/<x.x.xxxx>/workers/python/3./OSX/Arm64/grpc if you installed azure-fuctions-core-tools using homebrew. Otherwise it might be in a different location but the concept is the same. The whole directory needs to be copied to replace the grpc version provided in azure-function-core-tools with the correct one. Not sure why it is broken in core-tools for M1 but been like that for a while.
