pip install, error building wheel for annoy

[jdmoore7]

Hi team, this looks an incredible tool and I'm really looking forward to using it.

I've tried pip install skills-ml and it almost works, up until it tries to build a wheel for the package, annoy, at which point the installation runs into a fatal error and quits. I've installed annoy separately without any issues, however, pip3 does not seem to be able to locate this when attempting to install skills-ml.

Is there a precompiled version of skills-ml available, dependencies and all?

I experienced the same error and was able to get this to work. The issue is that the required dependency is listed as Annoy 1.14.0 which I guess no longer has the whl file to build from in pypi. When you separetely installed annoy, you probably installed 1.16.0 which installs correctly. To allow for this project to install, I downloaded the repo and changed the Annoy dependency version and then installed the local copy. I'm not sure yet if updating this package will break other things but doing so will resolve that error.

I had the same problem, and I can confirm that @nickcastro suggestion worked for me as well, and after running pip install . in the project folder, the package was successfully installed. Thanks!

Also note that the requirements appear to be missing wrapt package, which was required once I tried from skills_ml.ontologies.onet import Onet. This can, however, be easily fixed.

I have the same problem, but due to gcc version.
I did

yum install centos-release-scl
yum install devtoolset-7-gcc*
scl enable devtoolset-7 bash
which gcc
gcc --version

then pip install . again and it is solved :)
