problem on M1 building wheels for depthai

nicsandiland

I'm new to the Oak-D and have depthai working fine on my older intel Mac. However, I'm constantly having problems trying to install on a new M1 Mac which keeps reporting the following:

ERROR: Could not build wheels for depthai, which is required to install pyproject.toml-based projects

any suggestions as to how to resolve the issue?
thanks.

Hi nicsandiland ,
What version of depthai are you trying to install? As we have added prebuilt wheels for our library some time ago (see here).
Thanks, Erik

HI Eric,
I was using the following script to install:
python3 -m pip install opencv-python --force- reinstall --no-cache-dir
presumably, this would install the latest version?
thanks,
Nic

Hi nicsandiland ,
That's for opencv-python, not for depthai. I am not sure about the status of prebuilt m1 wheels of opencv.
Thanks, Erik

Sorry I pasted the wrong line:

Hi nicsandiland ,
What's the version of your python? From the pypi (link above) I found prebuilt wheels for mac arm64 (m1) for python versions 3.9, 3.10 and 3.11. If you have those - could you try force reinstall it?
Thanks, Erik

depthai-2.20.2.0-cp39-cp39-macosx_11_0_arm64.whl
depthai-2.20.2.0-cp310-cp310-macosx_11_0_arm64.whl
depthai-2.20.2.0-cp311-cp311-macosx_11_0_arm64.whl

Hi Erik,
I've been trying different versions of Python installing and uninstalling using pyenv. I currently have 3.11:

(venv) nicsandiland@Nics-MacBook-Pro pythonProject % pyenv versions

system (set by /Users/nicsandiland/.pyenv/version)
3.11.1
(venv) nicsandiland@Nics-MacBook-Pro pythonProject %

I've downloaded the respective file you suggested but am getting an 'unsupported' error:

(venv) nicsandiland@Nics-MacBook-Pro pythonProject % pip3 install depthai-2.20.2.0-cp311-cp311-macosx_11_0_arm64.whl
ERROR: depthai-2.20.2.0-cp311-cp311-macosx_11_0_arm64.whl is not a supported wheel on this platform.

thanks,
Nic

Hi nicsandiland , which macbook pro do you have? This year's one? We will take a look at this issue.
Thanks, Erik

I've literally just bought it, though it's not the most recent model:
14" 2021 M1 Pro 16GB
Monterery 12.6.3

thanks

@nicsandiland thanks for the report. Do you mind running these:

pip3 --version
python3 -m pip --version
python3 -c 'import platform; print(platform.machine())'
python3 --version

and pasting the output?
