Ok, it compiles and runs fine for me on MacOSX Sierra 10.12.1
The things I did to get it to compile:
- install gcc 5.2.0 with
brew install gcc --without-multilib - Change line 9 of CMakeLists.txt in
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS} -O3 -fPIC -ffast-math -funroll-loops -lstdc++") - compile with command
export CC="/usr/local/Cellar/gcc/5.2.0/bin/gcc-5"; export CXX="/usr/local/Cellar/gcc/5.2.0/bin/gcc-5"; python setup.py install
Thank for this work, it is really fast indeed !

thanks @thomwolf worked for me, except the current gcc version is 6.1.0, so: export CC="/usr/local/Cellar/gcc/6.1.0/bin/gcc-6"; export CXX="/usr/local/Cellar/gcc/6.1.0/bin/gcc-6"; python setup.py install
overall this is faster. for my task i see about 20% speedup to 8m45s running on 8 logical cores, compared to 11m for bh_tsne.

You're welcome @kylemcdonald, by the way I am a huge fan (and user) of your OF/sound work ! So thank you too (not to hijack this github issue :) )

I do not have mac, but you can try to modify cmake comand inside setup.py according to

Hey, thanks for that link. I managed to get cmake to use a gcc instead of clang my modifying the setup script:
os.system('mkdir -p multicore_tsne/release ; rm -r multicore_tsne/release/* ; cd multicore_tsne/release ; cmake -DCMAKE_C_COMPILER=/usr/local/bin/gcc-6 -DCMAKE_CXX_COMPILER=/usr/local/bin/gcc-6 -DCMAKE_BUILD_TYPE=RELEASE .. ; make VERBOSE=1')
that seems to work, but I get a different error message that looks like there's something broken somewhere else:

Can you try to remove this line ?

You shouldn't have to change the installation script. If you specify the path to GCC in the CC environment variable before running the installation script, it should use the right compiler.
In other words, typing the following in your terminal should do the trick:
export CC="/usr/local/bin/gcc-6"; python setup.py install
from multicore-tsne.

Hi @adelr, that isn't right. cmake doesn't listen to CC or CXX options. in any case, it doesn't solve the problem (please see error above)

Hi @sg-s, starting from the original (non-modified) setup script, on Mac OS 10.11.6 (with anaconda python 3.5.2 or 2.7.12) I get an error similar to your original one because clang is being used by default:

thanks @DmitryUlyanov, but that problem is when I used gcc5.4.
earlier, I had a different error, perhaps, linked to this:

I end up with the same error compiling with gcc 5.2.0 on MacOSX Sierra 10.12.1 (Undefined symbols for architecture x86_64).

Success! Thank you so much. Very, very excited to use this. Quick question, is this implementation analagous to the original author's implementation or based on the scikit-learn version because I stumbled across this github issue: scikit-learn/scikit-learn#8766 when I was trying to figure out if the learning rate was adaptive scikit-learn/scikit-learn#7215

Awesome 🙌🏽 That is the one I have been using. One last question, can a random seed be used with this version? Does that warrant a separate feature request ticket? Thanks again for your help.

Solved the same issues by installing gcc-mp-4.7 with Macports and building "by hand":
cd multicore_tsne/release
cmake -DCMAKE_C_COMPILER=/opt/local/bin/gcc-mp-4.7 -DCMAKE_CXX_COMPILER=/opt/local/bin/gcc-mp-4.7 -DCMAKE_BUILD_TYPE=RELEASE ..
cd ..
make VERBOSE=1
