This has been a bugbear of mine for sometime now. I like using Python 3.x. I like teaching kids how to use Pygame. Trying to get all three to play nicely with each other has been impossible for me up to now. I've trawled through web pages and blog posts that recommend all manner of ways in which you can install Pygame on a Mac for Python 3, I've tried numerous solutions on StackOverflow, and I've even tried angrily shouting at my computer and threatening to throw it out of my classroom window. None of them worked.
Today I finally nailed it, and I have Pygame running. Here' what I did. 1) Install XCode and command line tools 2) Install Homebrew (ruby -e '$(curl -fsSL 3) brew install Python3 4) brew install git 5) brew install sdl sdlimage sdlmixer sdlttf portmidi 6) Install XQuartz - 7) brew tap homebrew/headonly 8) brew install -HEAD smpeg 9) brew install python (needed to install mercurial) 10) brew install mercurial 11) pip3 install hg+And that's it. If you have any problems yourself or a better way then please let me know in the comments.
Step 2) Double click on the installer and follow the instructions for installing Python 3.2.3 on your Mac. Step 3) Now, when you open up terminal and type in 'python', version 2.7 still appears. To open the version you just installed, type 'python3' and this will open the latest version of Python 3.x.x. When a neuron is trained to act like a simple classifier, we call it “perceptron”. A neural network consists of a lot of perceptrons interconnected with each other. Let’s say we have a bunch of inputs and the corresponding desired outputs.

Note: the smpeg install is failing for me at the moment, so I'll look into this a little more. Pygame seems to be working without it though.
Update I had some brew doctor issues (around 20!), which might have been due to me trying to install Pygame from source earlier and therefore manually installing all the dependencies, which then conflicted with homebrew. I deleted everything brew doctor suggested and overwrote all links as suggested. The brew install -HEAD smpeg suddenly worked (although that might have been because I was no longer behind a proxy). I then did a brew unlink jpeg and brew link -overwrite jpeg. Everything is working perfectly for now.

How to Install XGBoost for Python on macOS Photo by, some rights reserved. Tutorial Overview This tutorial is divided into 3 parts; they are:. Install MacPorts. Build XGBoost. Install XGBoost Note: I have used this procedure for years on a range of different macOS versions and it has not changed.
This tutorial was written and tested on macOS High Sierra (10.13.1). Install MacPorts You need GCC and a Python environment installed in order to build and install XGBoost for Python. I recommend GCC 7 and Python 3.6 and I recommend installing these prerequisites using.
For help installing MacPorts and a Python environment step-by-step, see this tutorial:. 2. After MacPorts and a working Python environment are installed, you can install and select GCC 7 as follows.
