Question

I am a newbie and learning python. Can someone help me- how to install xgboost in python. Im using Mac 10.11. I read online and did the below mentioned step, but not able to

Answer 1

For Python-3.x, do the following in Mac

Make sure gcc-6 (and g++-6) is installed, if not do so with

brew install gcc

Then, do the following

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost/
make -j4
cd python-package
python3 setup.py install

If you are using Anaconda and haven't yet configured your path to use the binaries in ~/anaconda/bin, then run the last line as

/path/to/anaconda/bin/python3 setup.py install

Answer 2

All the other ways described here failed in my case. I managed to install by following the official installation described here: http://xgboost.readthedocs.io/en/latest/build.html#building-on-macos

My system is MacOS Serria so I followed the instruction of "Building on macOS".

However, instead of "replacing these two lines into(5 or 6 or 7; depending on your gcc-version" w.r.t. the config.mk file, I did:

export CC = gcc-5
export CXX = g++-5

Even though gcc-version showed Apple LLVM version 9.0.0.

After that by following the official instruction of "Python Package Installation" I was able to run the package in Python.

Im running Mac OS Mojave 10.14.5 and following the "advanced method" instructions for Mac OS at https://xgboost.readthedocs.io/en/latest/build.html# worked for me. In short:

brew install cmake 
brew install gcc@8
git clone --recursive https://github.com/dmlc/xgboost
mkdir xgboost/my_build
cd xgboost/my_build
CC=gcc-8 CXX=g++-8 cmake ..
make -j4
cd ../python_package
python3 setup.py install
