To run it blindly just copy the command in README.md and run it in your console.
For a more detailed explanation check out my blog post http://dacamo76.com/blog/2012/12/07/installing-scikit-learn-on-amazon-ec2 which details what each step does.
I copied the above link but it still doesn't work. Does it depend on Python version?
@rongyuan124 it depends on your OS, among other things. Are you on Redhat or the Amazon Linux OS? If not, you may need to change the yum install to apt-get install
I recommend adding
pip install -U pip
command before doing any of the pip install stuff.
There seems to be some issue with the default pip version, which give out the following error sometimes when installing scipy
Traceback (most recent call last):

Tamaki thanks for your input.
It really helped me.
This script did not install scikit-learn for me, I instead made my own bootstrap script:
#!/bin/bash
sudo pip install numpy
sudo pip install scipy
sudo pip install -U scikit-learn
Hello, I am trying to run mrjob script on amazon ec2 and in order to do that, I need to install scikit learn on amazon. Can you please explain how exactly to run your code, I am pretty new to this. Thanks!
