Cannot get scikit-learn installed on OS X

问题

I would like to use scikit-learn on an upcoming project and I absolutely cannot install it. I can install other packages either by building them from source or through pip without a problem. For scikit-learn, I've tried cloning the project on GitHub and installing via pip without success. Can anyone please help? Here is part of my pip.log:

Install SciPy Superpack or EPD to get all the required dependencies in one shot under OSX.

I came across this nice tutorial and with just a few straight forward steps you can install it via PIP like this:

(Only the outlines. For details visit the authors page.)

install Xcode
install pip
install brew
install NumPy
install gfortran (important!)
install SciPy
install matplotlib (useful)
install scikit-learn
test

Also see the comments on the authors page for how to install PIP and Virtualenv.

If you use Homebrew, then these two commands should do it for you:

brew tap homebrew/python
brew install scipy

回答4:

You can use pip to install scikit.
