Running DepthAI on Apple M1 Based Macs

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 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.

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.

Hernia Please let us know if the above command work for you, so we can release the new M1 wheels to pypi
Thanks, Erik

Did receive this warning:

note: This is an issue with the page at the URL mentioned above.
hint: You might need to reach out to the owner of that package index, to get this fixed. See https://github.com/pypa/pip/issues/10825 for context.

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!

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:

drwxr-xr-x 5 gregflurry staff 160 Jun 16 15:21 depthai

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.

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!
Erik

erik Here is the latest:

(venv) gregflurry@Gregorys-MBP examples % python install_requirements.py

RuntimeError: There are no prebuilt wheels for M1 processors. Please open the following link for a solution - https://discuss.luxonis.com/d/69-running-depthai-on-apple-m1-based-macs

I was running in a native Terminal, the same one where I ran the installation of the wheel(s). I seem to be missing something. I am certainly confused!

@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.

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

erik This time, I'll apologize up front. I know very little about git, pip, etc. I've done some searching, including Luxonis documentation, but I cannot determine the proper parameters for the 'git checkout' command.

I looked at the install_requirements on my system, and I can see that simply assumes the M1 wheels don't exist. So, I believe that the checkout downloads new code that does not make that assumption. That said, due to my lack of skills, I'm not sure where git will put the new code and what I do with the old code.

I've reached a point of guilt about taking up too much of your time on this. After today, it will be more than a week before I can do anything on this (vacation). I wonder if it might be better for me to wait until the entire arm64 native install has been defined, tested, and documented. That way you don't waste valuable time guiding clueless me through the process one step at a time. That said, I'm still willing to continue the "one step at a time" until I have to quit.

@gregflurry Could you try the following:

1. Open a terminal, navigate to depthai-python folder
2. Execute git checkout mac_arm64_wheels
3. Execute python examples/install_requirements.py
4. Execute python examples/ColorCamera/rgb_preview.py

erik Step 2 failed. I started with a new native Terminal. There must be something I'm not doing properly. Here is what I get:

gregflurry@Gregorys-MBP ~ % cd depthai-python
gregflurry@Gregorys-MBP depthai-python % git checkout mac_arm64_wheels

Step 2 seems to continue to run the old code that simply asserts M1 wheels don't exist.
