BOLT for python 3?

[Sun694]

I was unable to get BOLT working on python three after a bit of debugging.

I finally tried pip installing it, and see an error message stating only python 2.6+ is supported.

Is there any way to get python 3 supported?

I should be more verbose: All I'm trying to do is calculate a fast dot product between a given query and a set of keys.

When trying to do python setup.py install, I get a string of errors ending with:

This might be completely unrelated to python2/3, and if you have a solution to this issue instead, then all is perfect 👍
Thanks

Update: This error happens even on Google Colab with Python=2.7, so I don't think this is actually a python version issue.

That being the case, have any ideas?

@dblalock -- I'm getting the same error as @Sun694.

For what it's worth, I was able to install your swig-numpy-example repo and successfully run python test.py. So I think my swig install is working fine.

In addition, I tried forcing clang++, which again led to the error above. But unlike the person in Issue #4, compiling your simple main.cpp with clang++ main.cpp -o main.out -std=c++14 -stdlib=libc++ works for me.

I'm getting a similar error in Colab, is there a fix?

Thanks for the bug report! Running out of time tonight, but will look into this tomorrow.

[dpalbrecht]

@dblalock thanks very much! Looking forward to running it

It looks like this is the same issue as #4? Going to keep further discussion over there to get it all in one place.

Feel free to reopen if it looks like this is a separate problem.
