… and our Python installation provides an utility named python-config, that knows everything about libraries and include directories: $ python3-config -includes Users/xperience/.pyenv/versions/3.9.5/bin/python3 Pyenv itself can tell us where the binary is for Python, that’s one down: $ pyenv which python3 This presents a problem: Where can we find these paths, assuming we have a non-system python? (Don’t forget that if you’re doing this locally the paths can be different than those shown below.) Now, we should provide these 3 options to cmake to get python3 module built:
PYTHON FOR MAC M1 INSTALL
First, we’ll set the active version of Python to 3.9.5, make sure pip is up to date, and then install the python packages needed for the build: $ pyenv local 3.9.5 I installed python 3.9 from pyenv – as easy as: $ pyenv install 3.9.5 After that, I started doing the build – not the Python package, initially, but OpenCV itself with the Python bindings. Starting in the evening, I opened my laptop, connected via ssh to the M1 machine, checked that all the tools were ready and cloned the OpenCV repository. Using the above tools, we have all we need to set up our requirements and move on to building. Using this Ansible collection that allows you to install any GUI application from Apple store we will set up XCode which is, of course, Apple’s recommended IDE. That said, having a compiler isn’t enough, we need an IDE. Let’s not forget we still may need some GUI applications – yes, this machine is for CI, but imagine that at some point you’d like to debug some functionality. Ansible is one of the most used tools in this area, and has a good track record, so we’ll go with it. On top of that, automation requires some glue between different tools to configure them, provide the needed setup, and report issues in standing up new machines. The free Homebrew is great third-party package manager for macOS which we’ll use for this purpose.

Since we’re talking about automation, we need to be able to install software from the command-line to efficiently manage dependencies. My tool of choice when it comes to managing python interpreters on one machine is pyenv (yes, we know there are others).
Since we want to support multiple Python versions, chances are we’ll have more machines in the future, so we’ll want to automate the environment setup. However, for our continuous integration machine, we need to do a few additional steps. I started with the official tutorial on building the current version of OpenCV for macOS.
PYTHON FOR MAC M1 HOW TO
How to set up macOS for OpenCV development Not the ones prior to it.Grigory Serebryakov is OpenCV AI Chief Development Officer. In another forum I learnt that 3.9.1 is the python supported for Monterey. Make: *** No targets specified and no makefile found. noĬonfigure: error: Unexpected output of 'arch' on OSX noĬhecking whether pthread_key_t is compatible with int. Results logged to /var/folders/3f/l881d_r17qj_2q0kt5_6ll9h0000gn/T/Ĭhecking whether to enable large file support.
However, when I used brew install for all packages including pyenv, pyenv-virtualenv - I was able to have multiple python virtual environments on 2.7.18, 3.9.9 on latest Monterey using M1 silicon 14" pro.įor default Python 3.8.9, I am seeing build errors for pyenv install 3.8.9 command: pyenv install 3.8.9īUILD FAILED (OS X 12.0.1 using python-build 20180424)
PYTHON FOR MAC M1 UPDATE
An update on /intro-to-pyenv/ I had issues with pyenchant not being able to find enchant C library when I used pyenv installer as suggested in this link.
