Import FTRL fails

[voglinio]

I have tried to install from source both 1.3.3 and 1.3.5 versions. When issuing the import FTRL commands I get a strange "Ilegal instruction" message.

I am working on an Ubuntu 14.01 system and install python3.6 in a virtualenv. Other than some warnings:

wordbatch/models/fm_ftrl.c:2916:10: note: ‘__pyx_v_d’ was declared here
   double __pyx_v_d;

I don't see any suspicious in the installation.
This is the message I get:

(python36) voglis:~$ python3
Python 3.6.5 (default, Mar 29 2018, 00:00:00)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import wordbatch
>>> from wordbatch.models import FTRL
Illegal instruction (core dumped)

And this is my Python package list:

(python36) voglis:~$ pip list
