So we got our Mac mini M1, and gave it a quick try running DepthAI on it. Got our prebuilt wheels (for Intel CPUs - x86_64) working very well using the Rosetta emulator. First, the native Apple Silicon support for Homebrew is still being actively worked on (with several issues still existing), so I didn't attempted installing it / building from sources. See https://github.com/Homebrew/brew/issues/7857 The steps followed: Install Rosetta (note it may be already installed, for example attempting to install other apps (current TeamViewer) may prompt to install Rosetta first): softwareupdate --install-rosetta To run commands with x86_64 emulation, it is possible to prefix them with arch -x86_64 But there's an easier way, to open the terminal app directly using Rosetta. For example, I copied Terminal to Desktop, renamed it to Terminal-x86_64 , and tick the checkbox Open using Rosetta : Then after opening the terminal, it can be checked under what architecture it runs using uname -m with Rosetta it prints: x86_64 native: arm64 After that, it's just the standard procedure to install Brew (it installed python 3.8.2 by default), clone depthai repo, running ./install_requirements.py , and finally ./depthai_demo.py . Cheers, The Luxonis Team

I was able to follow the instructions here for Mac with no issues on my M1 Macbook Air, however I used iterm2, and not terminal. I also did not run it in rosetta mode. I am, however, having issues with connectivity on both a USBA-> C cable that came with the camera with an additional USBA->C adapter, and a short USBC/Thunderbolt cable (which I would assume would work) Running with --force_usb2 works for now.

smd58tex Thanks for following up!

With a new Oak-D-Lite on my Mac Mini M1 Monterey, using a 2nd Rosetta enabled Terminal that shows "uname -m" is x86_64, I was unable to run "python3 -m pip install depthai", apparently due to conflict with the "default" installation in /opt/homebrew.

Hello RobotRoss , what do you mean by 2nd Rosetta enabled terminal? We should have prebuilt wheels for that (x86_64), so I am not sure why it's trying to build new wheels for that. Which python version are you using? Thanks, Erik

Erik, Tnx for response. My (Homebrew) installed python3 from arm64 terminal.app (uname -m arm6) is: which python3 /opt/homebrew/bin/python3 Ross@Kepler-2 ~ % python3 --version Python 3.9.9 From x86_64 terminal-rosetta2.app which python /usr/bin/python Ross@Kepler-2 ~ % python3 --version Python 3.9.9 I have a 1st native “terminal.app”, uname -m arm64. Homebrew is installed in /opt/homebrew & there is text in the PATH environment to this folder. This is the default, per this response to 'brew config" from the Native arm64 and Rosetta x86_64 terminal. From arm64 terminal.app Ross@Kepler-2 ~ % brew doctor Your system is ready to brew.

There is a 2nd homebrew installed in the pre-M1 folder /use/local/homebrew This text is not in the PATH. I ran the python3 -m install_requirements.py from this Rosetta2 enabled terminal, with the earlier posted result. The system seems to want to run the arm64 version of Homebrew Python to build your depth wheels, even while using the x86_64 terminal, probably because of the PATH text , with the resulting errors. Is there a way to force the system to stay with the x86_64 terminal Homebrew for running python3 ? So since the Mac M1 has been out for over a year now and presumably Homebrew has matured, can you release a native arm64 depthai wheel? I’d rather not potentially break my current Homebrew jury rigging the x86_64 Rosetta2 terminal. I note there are other Data Scientist packages in arm64 Homebrew , such as numpy, scipy. Regards RobotRoss

To all users of M1 Mac that would like to use DepthAI, I recommend you to build a VM with Ubuntu ARM. My OAK-D works like a charm on it!

Yes, I can confirm the same success with a Ubuntu 20.04 VM on my Mac M1 and that the scripts run fast. As described for a Linux installation, must enable the udev rule. I will look forward, though for release of a native MAC arm64 Homebrew wheel installation. I’ve also installed the depthai on a Jetson Nano B01 Ubuntu 18.04 and Raspberry Pi 4/4G Raspi OS Buster 32 bit arm7.( though the compile takes 35 mins)

Hello RobotRoss , looking at piwheels , we should have 2.13.2 pre-built wheels for arm6/arm7 (python 3.7/3.9), as on the img below. Thanks, Erik

Hi everyone!! Yesterday I received my flaming new OAK-D Lite, and after 30 minutes my experience is not that D-Litefull ;-). And I haven't even plugged it in 😅 . I've followed Brandon instructions and copied a Terminal app on the desktop, selected Open using Rosetta, checked that the uname -m was X84_64 , and still get the following error (exactly the same I had before re-creating the "Rosetta Terminal"): Error: Cannot install under Rosetta 2 in ARM default prefix (/opt/homebrew)! To rerun under ARM use: arch -arm64 brew install ... To install under x86_64, install Homebrew into /usr/local. I have checked that there is a Homebrew folder in /usr/local, but I guess the code is using the native Homebrew installation. Any ideas or suggestions EDIT: I have fixed this with: export PATH=/usr/local/Homebrew/bin:$PATH in case it helps someone.

If the Terminal is enabled for x86_64 ("Use with Rosetta" box checked" and there is NO previous Homebrew installed in the native arm64 Mac, this may work. The problem I had was that I had apreviously installed Homebrew which goes into /opt/homebrew space and sets "HOMEBREW_PREFIX: /opt/homebrew " and matching "PATH" locations. This apparently confuses the depthai installation scripts which installs another homebrew stack in "/usr/local/homebrew" space but does not completely configure the default paths . Execute " % brew config" to see your default path settings. While I have NOT yet followed these instructions, check out the #macos for posts by whab which uses a virtual environment: https://discord.com/channels/790680891252932659/924798973519216651/934391777811636294 .

weiYao

still no further progress in new M1 chips?I mean native.-_-.

erik

Hello weiYao ,
M1 runners aren't yet supported by Github, that's why we haven't yet added support for native M1, more info here. As soon as that comes out we will also add support for M1 on depthai.
Thank you for understanding, Erik

gregflurry

I am trying to migrate from a working DepthAI/OAK-D on an older (X86-based) MacBook to a new (M1 Max-based) MacBook. Using the standard (and naive, in retrospect) migration approach left me with nothing working, due to several issues, including Python locations and versions, non-functional Homebrew, etc. I think I've got all issues resolved, except for the lack of M1 native DepthAI. Based on this discussion thread and the DepthAI documentation, I seem to have 3 options I can: (1) run the X86 DepthAI using Rosetta; (2) build the M1 native wheels; (3) wait for Luxonis to produce the M1 native wheels.

My needs are currently not urgent; I'm not wild about Rosetta dependencies; from the thread it seems that with my level of system skills I'd never succeed at building M1 native wheels. That leaves waiting for Luxonis to produce the M1 native wheels. Is there an estimate of when that might happen? Thanks!

Brandon

This is not going to be automatically built:
https://github.com/luxonis/depthai-python/pull/604

And sorry for missing your comment @gregflurry . Fortunately this will now be done as soon as this finishes building (i.e. tomorrow).

gregflurry

Brandon This sounds exciting! That said, I don't fully understand. The GitHub link appears to suggest that M1-specific (not universal) wheels will get produced; that I think works for me. I'm unsure what you statement "This is not going to be automatically built" means. Does it refer to some Github restriction?

Assuming the wheels do become available somehow, can you estimate when the relevant documentation will get updated? Thanks.

erik

Hello gregflurry ,
We have just implemented building these wheels today. Could you try it out as well?
python3 -mpip install --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/ depthai==2.16.0.0.dev0+fc472bd13f9c853148e7a35fc956f4bc0dbf49ae

Thanks, Erik

Brandon

Yes it means that M1 will just install w/out having any other work. Will be equivalent to x86 Mac, or x86 Linux and/or all the standard builds we have now.

So this should be fully out this week when we do another release with this system.

gregflurry

erik Here is the latest:

Thank you for bringing support to the M series processors and latest Macs. My camera is sitting beside my new iMac, hopefully the two will be on speaking terms soon.

erik And more flailing .... I realized that I made yet another mistake; I did not execute the proper command from a new Terminal; sigh. When I opened a new terminal and ran the command with Python 3.9, the command succeeded. In the folder /Users/gregflurry/.pyenv/versions/3.9.5/lib/python3.9/site-packages, the command produced the following:

So, I think the native wheel(s) did get loaded. I'm now off to clone the repository. Then I'll test in a manual virtual environment, and then in PyCharm.

I attempted to install in what should appear to be a system with no DepthAI presence. For other reasons, I already had homebrew installed natively, and had Rosetta installed. I attempted to follow the installation instructions here using a native Terminal. I foolishly ran the command to install dependencies, and then read the paragraph after the command. During execution of the install script, I saw "Running in native arm64 mode, will prefix commands with: arch -x86_64", "Warning: Running in non-interactive mode because $CI is set.", "==> Installation successful!", " >> arch -x86_64 brew install python3 git", "Error: Cannot install under Rosetta 2 in ARM default prefix (/opt/homebrew)!"

I'm not sure what this means and how to proceed. All I can tell for sure is that I now have two copies of homebrew, one for arm64 and one for x86_64, plus a git installation, presumably for x86_64. I was unable to extract any useful hints from the link in the installation instructions regarding having a native homebrew. I would like to be able to remove the x86_64 homebrew installation. I don't know what to do about git; I have not checked if an arm64 git exists.

Despite my ignorance, I proceeded to attempt install depthAI using pip. That failed with the following:

I guess I need HELP!

gregflurry Sorry I should have mentioned that these wheels are (AFAIK) only for Python version 3.9 and 3.10 - so the second time it used 3.9 and wheels got downloaded correctly. Let us know if it works as expected, thanks!

@gregflurry instead of calling install_requirements, please try the command below. And just try running python examples/ColorCamera/rgb_preview.py after installing the wheel.

python -mpip install --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local/ depthai==2.16.0.0.dev0+fc472bd13f9c853148e7a35fc956f4bc0dbf49ae

erik Progress. Running rgb_preview does not complain about wheels now. However, now I have much more mundane problems; I'm missing the OpenCV and numpy libraries.

I think I successfully installed numpy the virtual environment. However, I don't know how to install OpenCV. Everything I read suggests I must build it, and, per earlier posts, I don't have cmake. Not sure how to proceed. And let me apologize up front for being such a pain.

erik

Hi gregflurry ,
I think opencv has wheels for M1 as well. Could you try git checkout to latest commit on mac_arm64_wheels branch and calling python examples/install_requirements.py (this will install opencv/depthai M1 wheels) and then python examples/ColorCamera/rgb_preview.py?
THanks, Erik
