There are several ways to install Git on a Mac. The easiest is probably to install the Xcode Command Line Tools. On Mavericks (10.9) or above you can do this simply by trying to run git from the Terminal the very first time. $ git -version. If you don’t have it installed already, it will prompt you to install it.

In this walkthrough Iinstall lightgbm on the latest version of R on an older model macBook Pro withMacos Catalina 10.15.5 and I’m using homebrew.

The world of boosted tree models is growing over the past 4 years, the firstrevolution was with ‘XGBoost’ (eXtreme Gradient Boosting) in 2016, followed by‘lightGBM’ (or LGBM) from January 2017 and later that year ‘catboost’. To usethese C++ libraries in R you have to install them, and that process is slightlydifferent for different architectures.

Prep

I’m also using the amazing RSwitch tool for the Macto switch R versions: from 4.1.0 “experimental version”, to the latest stable versionR 4.0.2 ‘Taking off again’ and an older version beforethat R 3.6.3 (2020-02-29) ‘Holding the Windsock’.I’m trying to install this library on all R versions, but if you use one versionof R, this RSwitch tool is not necessary.

I’m mentioning all this because sometimes these things are really difficult todebug under different operating systems, and different R versions.For work I installed lightGBM on a macbook a year ago, and it was a lot more work then.

Installation

I’m following the instructions at lightgbm.readthedocs.ioand you should too.

First I download the code to my computer:

I deleted the lightGBM folder and re ran the git clone command.

Continuing the installation: going into the lightGBM folderand executing the build_r.R script.

And a failure, I do not have openMP (a multithreading library) installed brew install libomp.I did have it installed, it seems, but it wasn’t linked brew link --overwrite libomp.This was a bit aggressive, it overwrites all links to libomp. I may have brokenthings later, but the installation continues and is successful.

(Re)start your R session and check if you can load the library library(lightgbm).

Installing on multiple R versions using RSwitch

I than used RSwitch to switch R version to an older version of R andreran the Rscript build_r.R command in the same folder.The process reruns the installation and because RSwitch switches the R versionthe package is now installed in the older R version location:the script spews out* installing to library ‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library’

(Re)start your R session and check if you can load the library library(lightgbm).once finished and verifiedI switch to R3.6 and rerun the script again.It now installs in* installing to library ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library’

And you are done.

How to install lightgbm with renv

Install Git On Mac Os Catalina Os

renv builds a separate libraryfor your project. This is cool, because it allows you to use different packagesthat do not influence each other. However starting a new project with renvdoes not have lightgbm installed.

I’ve found the easiest is to use setwd() in your R console to move to theLightGBM folder and then ssource('build_r.R') this will build the packageagain and place it in the correct library.

I thought there would be issues with different versions of R, but the main issuesare related to architecture: system libraries that you have to install on macos.After this installation the installation of the R wrapper is not really a bigissue anymore, at least not for R 3.6, 4.0 and 4.1 (at the time of writing).

How To Install Git On Mac Catalina

A quick tutorial on how set up a simple macOS VM in QEMU, accelerated by KVM. Jump over the break to learn more…

WHAT IS KVM?

Kernel-based Virtual Machine (KVM) is a virtualization module in the Linux kernel that allows the kernel to function as a hypervisor.

KVM converts Linux into a type-1 (bare-metal) hypervisor and requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V.

DEPENDENCIES

  • Qemu 3.1 or later
  • python3
  • pip
  • KVM modules enabled
  • A Mac computer is NOT required

How Install Git On Mac

INSTALL

1. Install dependencies. You might also want to install git (not shown in the screenshot ). Depending on your distro:

  • For Ubuntu, Debian, Mint, and PopOS: sudo apt-get install qemu-system qemu-utils python3 python3-pip
  • For Arch and Arch based distros: sudo pacman -S qemu python python-pip
  • For Void: sudo xbps-install -Su qemu python3 python3-pip
  • For openSUSE Tumbleweed: sudo zypper in qemu-tools qemu-kvm qemu-x86 qemu-audio-pa python3-pip
  • For Fedora: sudo dnf install qemu qemu-img python3 python3-pip

2. Clone this git https://github.com/foxlet/macOS-Simple-KVM.git and cd to path.

3. Run jumpstart.sh to download installation media for macOS (internet connection required). The default installation uses macOS Catalina, but you can choose which version to get by adding either --high-sierra, --mojave, or --catalina. For example: ./jumpstart.sh --mojave

4. Create an empty hard disk using qemu-img, changing the name and size to preference: qemu-img create -f qcow2 MyDisk.qcow2 64G

NOTE: Change “MyDisk” to your preffered disk name. Change “64G” to your prefered disk size ( min. 20G )

5. Edit basic.sh with sudo nano basic.sh and add this at the end:

-drive id=SystemDisk,if=none,file=MyDisk.qcow2
-device ide-hd,bus=sata.4,drive=SystemDisk

Save the changes and exit.

NOTE: change “MyDisk” to your disk name set in previous step.

6. Run ./basic.sh

Install Git Osx Catalina

7. Boot into macOS Catalina Installer

8. Go to “Disk Utility” and format your disk

9. Once your disk is ready, you can install macOS Catalina. From now on, it’s your typical macOS install. No extra steps required.

10. You’re done! To fine-tune the system and improve performance, look in the docs folder for more information on adding memory, setting up bridged networking, adding passthrough hardware (for GPUs), tweaking screen resolution, and enabling sound features.
