Pip install: Problems on OSX (Symbol not found: _cs_di_norm)

FWIW the issue exists in python 2.7.11

Python 2.7.11 (default, Dec 12 2015, 14:38:46) 
[GCC 4.2.1 Compatible Apple LLVM 7.0.2 (clang-700.1.81)] on darwin

pip install is not stable yet, and I'm surprised you found it ;) .
Currently only linux binaries are available on pip. I'm not sure if it's possible to "deactivate" pip for osx.
I'll open an issue with a detailed description about the current state of pip install asap.

I recommend to use the source install for osx in the meantime.

Thanks @ibayer. I don't have any experience with platform specific packaging but this link might be helpful:

I think egg might work on Mac OS X because it builds on installation.

[ibayer]

I just managed to build and upload wheels with travis. 😄
https://github.com/ibayer/fastFM-fork/releases
They work on linux. We could add this to master and I could upload platform specific wheel to pip
if this works on osx too.

[merrellb]

An OSX specific wheel would be great (happy to do some testing)

Strangely I note that the current pip install creates a file called

site-packages/ffm.cpython-35m-darwin.so

which seems very Mac specific given the lack of binary OSX support (perhaps this is just some pip "magic" renaming the Linux library?)

[ibayer]

OSX specific wheels are available here:
https://github.com/ibayer/fastFM-fork/releases
You could try them
Python 2.7
pip install https://github.com/ibayer/fastFM-fork/releases/download/v.1.5/fastFM-0.1.1-cp27-none-macosx_10_5_x86_64.whl
Python 3.5
pip install https://github.com/ibayer/fastFM-fork/releases/download/v.1.5/fastFM-0.1.1-cp35-cp35m-macosx_10_5_x86_64.whl

[merrellb]

Both seem to work great. Thanks!

On my Mac OS X which is Yosemite 10.10.5, fastFM could not install with wheel.

pip install https://github.com/ibayer/fastFM-fork/releases/download/v.1.5/fastFM-0.1.1-cp35-cp35m-macosx_10_5_x86_64.whl
fastFM-0.1.1-cp35-cp35m-macosx_10_5_x86_64.whl is not a supported wheel on this platform.

Result of pip freeze is here.

[merrellb]

You sure you are using Python 3.5?

[chezou]

Oh, sorry. I used Python 3.4.4

[chezou]

I confirmed I can use fastFM on Python 3.5!
