I was trying to install python package scikit-learn. I keep get an error.
I tried
pip install scikit-learn
The error looks like following. What is the problem of my installation?

I had the same trouble today, after trying many things the one that worked me was setting some environment variables before installing with pip resolved the issue for me:
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
And then install with sudo:
sudo -E pip install -U scikit-learn
it's seems to be a problem with xcode update (5.1.1 for me), it does not accept '-mno-fused-madd' as an argument, before it threw it a warning, know is an error, the first two commands ignore the unused arguments witch are the same that throw the error.
Hope it helps, any comments/corrections are welcome.

I'm trying to upgrade the scipy (currently I have version '0.11.0') on my machine, but I'm getting some compiler error that I can not work around:
When I invoke:
sudo pip install --upgrade scipy

Good day to everyone,
I've an error trying to compile and install Pygraphviz 1.2 in OS X 10.9

As you can see I've already installed graphviz with Homebrew.
The error is in clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]
Solution from clang error: unknown argument: '-mno-fused-madd' (python package installation failure) is:
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

Any idea what might be going on here?
This is a known issue with OSX and recent Xcode upgrade.
Instructions how to avoid the issue are here:

This should do the trick::

I am trying to install matplotlib on my machine with OS X 10.8 and XCode 5.0.2. I get these weird errors of which I am not able to make sense. I used pip install matplotlib to install the package, but then it returns the following errors at the end. I am clueless on what to do. Please help me proceed. I tried to install scipy through the same process and the same error stream prevails.

Although the installatoion proceeds a bit further, I get an error stream at a different point now.

That's a common problem, the last macos updates make clang generate errors instead of warnings for unknown compiler options. As a temporary workaround you could set ARCHFLAGS environment variable, before running pip:
export ARCHFLAGS='-Wno-error=unused-command-line-argument-hard-error-in-future'
I prefer to use Canopy as a python environment on OS X since it is usually harder to install python packages on a Mac.
You can get it here : https://www.enthought.com/downloads/.
MatPlotLib is installed by default, and many more packages are easier to install after installing Canopy.

I got this error while installing Cython from setup.py.
I was installing the scikit-learn package while get the same error. (-mno-fused-madd unknown argument)
Is there anything, any package needed before I install cython?
Many thanks
You need probably need to install another C compiler. Try compiling it with GCC.
clang: error: unknown argument: '-mno-fused-madd'
Alternatively, you can edit the configure script and change the compiler flags.
On a side note, this seems like it is a bug you should report.
